What’s the water like where you sail? Every ballast water treatment system has limitations related to water conditions. (Don’t let anyone say otherwise.) Which conditions are important depends on which technology you choose: electro c hlorination or UV treatment. If you choose electrochlorinationElectrochlorination (EC) uses electric current to produce disinfecting chlorine from salt water. That means there has to be salt – and even water temperature makes a difference.Salinity (salt content)Why it matters:Without salt, an EC system can’t produce chlorine for compliance. So long as you sail in salty seas, that’s not a problem. But different areas have different amounts of salt. And if you sail into brackish or fresh waters, there’s definitely not enough of it.What it means if you sail in less salty waters:1. You’ll need to carry salt or salt water on board.2. You’ll probably have to add a tank or use the aft peaktank (APT) for storing salt water. If you use the APT, you won’t be able to optimize your trim – which means higher fuel costs. 3. If you can’t supply the system with enough salt,you won’t comply.How they affect ballast water treatment systemsUnderstanding salinity, temperature and UVTWater temperatureWhy it matters:Electrochlorination works fine in warmer waters. But not everyone sails in the tropics. The colder that water gets, the less chlorine electrochlorination produces – and the harder it is to comply.What it means if you sail in colder waters:1. You’ll need to add heating equipment to keep theballast water warm. That’s additional CAPEX that’s probably not in your supplier’s offer.2. Heating requires energy, so OPEX in colder waters willbe higher too.If you choose UV treatmentUV systems use ultraviolet light to disinfect the ballast water. No chemicals are involved, and they’re notaffected by temperature or salinity. But you do need to be aware of UVT.UVT (UV transmittance, i.e. clarity)Why it matters:For UV light to neutralize organisms, it has to be able to reach them. UVT is a measurement of water clarity, i.e. how easily UV light travels through the water. UVT varies from port to port, but it makes a big difference. If you only sail where UVT is high, most UV systems will be fine. But many ports have low UVT. In those ports, some UV systems will use more energy – and some won’t comply at all.What it means when selecting UV systems:•The lower the UVT value on a system’s typeapproval certificate, the more ports you can call on. • A system that handles lower UVT may use lesspower where UVT is high (if it offers power management).100002706-1-EN 2007How to contact Alfa LavalUp-to-date Alfa Laval contact details for all countries are always available on our website at Alfa Laval reserves the right to change specifications without prior notification.What does all this mean for Alfa Laval PureBallast 3?Here’s a quick overview of how holding time applies to Alfa Laval’s ballast water treatment solution.Salinity•No impact on PureBallast 3 (UV technology) •No additional tanks needed•Aft peak tank can still be used to optimize trim Temperature•No impact on PureBallast 3 (UV technology) •Energy-efficient compliance even in the coldestwatersUVT•PureBallast 3 handles the lowest UVTvalues of any system •Compliance down to 42% UVT inIMO-regulated waters •Compliance down to as low as 55% UVTin USCG-regulated waters** The difference compared to IMO comes from differences in type approval methods.

Wellhead Liquids Measurement, What’s an Industry To Do?Mark V. Goloby©TC Technologies6702 Green StoneHouston TX 77084Liquids measurement in the oil patch is suddenly getting a lotof attention. Some are dismayed at the low level oftechnology used to measure liquids. Today, custody transferof 80 to 85% of onshore crude and condensate production isstill documented by a hauler climbing to the top of the tankand strapping it. “That would be a fair estimate,” concursMark Davis Staff Engineer Shell Exploration and Production. The hauler straps the tank before loading his truck and again when he finishes. The producer is paid on whatever thathauler writes on the ticket.“I did not realize it was that immature,” remarked Grant Farris, Vice President Producer Services, CIMA Energy.So, why it is that immature? Simple, really. The UnitedStates is experiencing the highest level of active liquids exploration and production in 40 years. Five years agofinding an oil play at NAPE was almost impossible. Whilethe industry was diligently automating gas measurement tothe digital world via electronic flow measurement, oil at$30/bbl and 15bbls/day was not given the same level of attention nor effort. These dynamics have changed.The characteristics of produced fluid at the wellhead are justthe first hurdle to accurate liquids measurement. Full well stream production is a very complex combination of oil, gas, condensate and/or water. Measuring any one of these components accurately is difficult. In combination, theymake liquids measurement a real challenge. Furthermore, the produced fluid may undergo 2 or 3 phase separation or no separation at all. These facility design decisions dictate the measurement solutions available and the degree of accuracyto anticipate.A typical production scenario has the produced fluid broughtto the surface then processed through a 2 or 3 phase separator. The result is gas goes to sales or gas-lift, water andoil goes to their respective tankage. If a 2-phase separator is used, the gas goes to sales and the oil and water combination goes to tankage for gravity separation.To develop effective solutions, producers need to help solution providers by answering questions such as: where in the production process should the liquids be measured? Since the custody transfer point for 80 to 85% of oil and condensate is by strapping the tank, does this mean tank level monitoring is more important? Will the industry entertain changing the custody transfer measurement point? Is the industry just interested in automation of the custody transfer point or does industry want more of a production monitoring tool or combination thereof? With today’s remote monitoring and automation technology what production information does industry want to gather? What decisions does industry want to make with this information? Solution providers need these answers to deliver cost effective automated liquid measurement solutions.No one defends the accuracy of the tank strap method of liquid measurement. So, how do industry suppliers develop consistent cost effective solutions? First, where in the production cycle do producers want to measure? Let’s explore some of the key aspects to consider when determining the optimum wellhead liquid measurement point then delineate a state of the technology to accomplish it.At the separator:Depending upon the separation equipment installed, comingoff the separator dump provides a good measurement on produced fluid for the hydrocarbon and/or water. This information can be quite helpful for reservoir analysis and management of production activity. However, coming out ofthe separator through the dump valve creates an issue of turbulence and flow characteristics that can affect measurement accuracy. In addition, even the most efficient separator cannot pull enough of the entrained gas out of suspension to avoid measurement. This gas will go throughthe metering equipment and be measured as a liquid component only to flash off as it sits in the tanks awaiting transport. With so many variables in play, from fluid characteristics to the type of facilities deployed, a host oftests are needed to insure accurate and repeatable measurement.At the tank battery:Tanks continue to be the custody transfer measurement point. Automated measurement of production here has distinct advantages. One is the ability to know the entire aboveground inventory. While across the field, any one tank maynot have a complete load to take to market. With the abilityto see all the tanks in the field a number of tanks can be aggregated and hauled to market. Armed with this knowledge, critical decisions based on need for cash flow, commodity price advantages and many other factors can beused to more strategically monetize production. More sophisticated measurement and software analytics canprovide more precise liquid production, but solutionproviders need the producer’s feedback to develop this incost effective packages. This information in turn can help production engineers monitor and optimize well performance. Tank level monitoring has the added advantagein that the fluid will be brought closer to atmospheric condition. Its measurement will then coincide more with the hauler’s; reducing discrepancies and the resulting reconciliation issues.At the loadline or pullout:Measurement at the load line is more a function of the producer community rethinking how liquids are exchanged than it is for the solution providers to deliver the requisite measurement equipment. However, identifying exactly how much fluid was loaded in the hauling vessel could be the ultimate liquid measurement data point that can satisfy the needs of both production and accounting. Test separators would still be required to establish baseline production per well but actual sales could tie nicely for most other reporting requirements. Such a solution could save time for the hauling companies as well. Filling up a tank truck could be as automated as your neighborhood gasoline dispenser. Capturing all the relevant custody transfer information on who, when, where and how much. Measuring at this point in the process alleviates many of the reconciliation issues between production and sales and aids tremendously with the reporting requirements of partners, royalty interests and regulatory.A variety of tools and techniques are available to measure at these points of production. From here is a brief presentation of the most common equipment, its advantages and disadvantages. All these solutions need more input from producers to perfect them.Fluid measurement off the separator:Liquid flow measurement technology abounds, but flow turbulence and fluid phases off the separator eliminate many of them. Keep in mind most flow measurement apparatus is based on a process of continual flow in a more controlled environment. Almost none of these conditions exists at the wellhead.Practical solutions available: Turbine Meter, Coriolis Meter, Positive Displacement Meter.Turbine Meters due to their moving parts are not as accepted as they once were. The fluid passing through the meter rotates a turbine that has magnetic pick-ups which due to the hall-effect produce an electro-magnetic pulse. These pulses are counted and accumulated to produce a rate and a total produced fluid measurement. Advantages: easy to understand, install, calibrate and inexpensive. Disadvantages: moving parts make them somewhat of a maintenance issue, inaccuracy due to entrained gas still in the fluid. Flow conditioning is needed to address fluid turbulence off the dump valve through the meter.Coriolis Meters are taking the market space left by the decreased popularity for turbine meters. The property of operation is the behavior of mass on a rotating structure which responds to the Coriolis force. The rotation is provided with a vibrating tube through which the fluid flows. The fluids effect on the tangential plane of the vibrating tubes can be measured and a flow rate computed. Advantages: very accurate, no moving parts. Disadvantages: difficult to install and maintain, while accurate, susceptible to the same issues of measuring entrained gas and the rigors of wellhead operations, expensive.Positive Displacement MetersHere too is a device well known in the industry typically installed at high volume custody transfer points. The measurement concept is the fluid is passed into precise volumetric increments and those increments are then counted usually mechanically but can be digitized utilizing the hall-effect similar to a turbine meter. PD meters have the advantage of approvals by a number of regulatory bodies. However, the PD meter is more typically associated as a component in a larger LACT unit device which is precise and takes into accounts basic sediment and water, and temperature. Even so, LACT units are typically proved for each liquid transaction.Tank Level:The tank level is the primary location for custody transfer of most liquids at the wellhead. Tank level solutions are very diverse and many, if not all, have been applied in the field. Some have proven more robust and up to the rigors than others. The focus here is on tank level measurement with outputs that can be digitized for SCADA monitoring and reporting of the actual fluid in the tank not just fluid level alarm solutions for overfill or spillage avoidance. Measurement solutions considered here are ultrasonic, guided wave radar, float systems and hydrostatic pressure. Ultrasonic devices rely on a time interval of a transmitted signal to the surface of the fluid and its return to the sensor. While this has potential; foams, surface agitation and other factors have rendered it more as just a sophisticated high level alarm solution.Ultrasonic measurement only measures to fluid surface level. It cannot measure the fluid cut level of oil and water. Hydrostatic Pressure measures the fluid level based on the fluid column pressure on a transducer at or near the bottom of the tank. While accuracy can be achieved under the low level of pressures involved, there is no way to distinguish the cut level between oil and water. The appeal of the device is ease of installation, maintenance, especially submersible models, and low cost. As the industry still relies on tank strappings to capture custody transfer, this solution can be a very cost effective manner to track fluid production and movement. Float systems are also a fairly straightforward solution. A float usually with a magnetic pickup traverses a rod embedded with wiring or sensors that detects the magnetic field to locate the device that equates to the corresponding fluid level. Floats can be weighted to the specific gravity of oil or water to simultaneously track oil and water levels. Float systems are very accurate and can provide a distinct measurement of oil and water simultaneously. Installation issomewhat difficult and buildup on the rod within the fluid can cause the floats to get stuck hindering performance. Devices are somewhat expensive.Guided Wave Radar is an advancement on radar detected tank level by adding a probe or cable with which to guide the radar signal. While the insertion of a probe is required there are no moving parts within the medium measured and guided wave radar can measure the fluid cut level for oil and water. Issues are again installation within the tank and the device can be expensive compared to alternatives. Measurement at the pullout or load lineThis is a somewhat radical change and would require a big shift in the industry’s thinking on fluid measurement and transfer. However, many of the aspects of the fluid that make it difficult to measure earlier in the production process are eliminated as the hydrocarbon becomes more atmospheric thus more consistently quantifiable. Higher cost devices such as coriolis meters or PD meters can make more economic sense as they can become the custody transfer point with an electronic record of when the load was taken, by whom and how much. This data can be conveyed wirelessly to all parties to the transaction. The difficulty in this scenario isn’t the measurement solution; it is the rethink the industry must make to its operations, contractual terms and reporting.In conclusion, as liquid production takes on a more significant portion of the oil and gas window, more sophisticated and updated measurement technology is needed. While a wide variety of devices and solutions to measure and collect production data are available, solution providers need input from producers, to develop and refine these tools to improve their accuracy and achieve economies of scale.Bibliography“State of the Flow Industry”, Flow Control December 2008 with abstracts from Spitzer and Boyes LLC.“Matching the Flowmeter to the Application” Greg Livelli, Flow Control August 2007 “”Coriolis Mass Flowmeters Used to Measure Bulk Condensate in Gas Field” Mark Davis, Jerry Stevens and Michael Keilty Pipeline and Gas Journal July 2010“Knowing the Limits of Ultrasonics for Crude Oil Measurement” Raymond Kalivoda Flow Control August 2008“Positioning for Market Share in Custody Transfer of Oil & Gas” Jesse Yoder and Belinda Burum Flow Control July 2011“Weighing Your Level Measurement Options” Gene Henry Flow Control July 2008The author would like to thank Jason Churchill, Venado Oil and Gas; Terry Hargrave, Chesapeake Midstream and David Pulley for their review and assistance with the article.

拖轮空放英语Tugboats, also known as towboats or simply tugs, are specialized vessels used for towing or pushing other vessels or structures. With their powerful engines and strong hulls, these boats play a crucial role in the maritime industry. In this article, we will explore the importance of tugboats and their various applications.Tugboats are primarily used for assisting larger ships in ports and harbors. They help maneuver vessels that are difficult to control due to their size, shape, or lack of propulsion. Tugboats are often called upon to guide massive cargo ships, tankers, or cruise liners through narrow channels or congested areas. Their ability to push and pull these vessels ensures safe navigation and prevents accidents or collisions.In addition to their role in port operations, tugboats are also essential in offshore industries. They assist in the installation and maintenance of offshore structures such as oil rigs, wind farms, and floating platforms. Tugboats are responsible for towing these structures to their designated locations and providing support during construction or repair activities. Their powerful engines and stability make them ideal for working in harsh weather conditions and rough seas.Another important application of tugboats is in salvage operations. When a ship is stranded, grounded, or involved in an accident, tugboats are called upon to provide assistance. They help refloat the vessel or tow it to a safe location for repairs. Tugboats are equipped with specialized equipment such as towing winches, anchors, and powerful pumps to handle these challenging situations. Their expertise in maneuvering and their ability to generate high levels of bollard pull make them invaluable in salvage operations.Tugboats are also used in the construction and maintenance of ports and waterways. They assist in dredging operations, where sediments and debris are removed from the seabed to maintain or deepen navigation channels. Tugboats tow dredgers and barges, ensuring efficient and effective dredging operations. They also play a role in the construction of bridges, underwater pipelines, and other marine infrastructure projects.Furthermore, tugboats are vital in firefighting and emergency response. Equipped with firefighting equipment such as water cannons and foam systems, these boats can quickly reach the scene of a fire on a vessel or in a port. Their agility and maneuverability enable them to provide immediate assistance and prevent the spread of fire.In conclusion, tugboats are indispensable in the maritime industry. Their versatility and strength make them essential for various tasks, including assisting large vessels in ports, supporting offshore operations, salvaging stranded ships, maintaining waterways, and responding to emergencies. Without the assistance of tugboats, many maritime activities would be significantly more challenging and dangerous. These powerful vessels continue to play a vital role in ensuring the safety and efficiency of maritime operations worldwide.。
APPROACH TO A LEAK ON AN LNG TANK BOTTOM Z. MEBATLACDS Research Ltd., Suite 100,565-l 7th Street, West Vancouver, B.C. V7V 3S9 (Canada) (Received December 1,1989; accepted in revised form March 5,1990)SummaryA leak on an LNG tank bottom often presents a challenge in identifying its location, type of leak and its cause. This is due to the lack of accessibility and inadequate instrumentation. Safetyconsiderations, however, dictate that at some point, the leak must be repaired and the tank certifiedfit for service. This paper addresses some of the practical considerations required to preparematerials, manpower and procedures for tank repair.IntroductionLarge liquefied natural gas (LNG) tanks are typically designed for a vapourpressure of the order of 6.9 kPa, in accordance with API 620, Appendix Q[1].The LNG is contained in a primary container, suitable for the liquid temperature,surrounded by sufficient insulation to maintain the rate of boil-off withinthe design specification.An outer tank made out of carbon steel keeps the insulation in position andprovides a vapour barrier for the boil-off gas generated in tanks with a suspendeddeck.The outer shell and roof are exposed to the site ambient conditions.A heating system installed under the outer tank bottom maintains atemperature of approximately 4℃, to prevent the frost line from penetratingthe tank foundation. Natural ventilation on elevated foundation slab designsmeet the same objective.A failure in the carbon steel outer tank bottom results in the release of boil-offgas only. The latter circulates from the tank dome space, along the annularspace, to the leaking point, for tanks with a suspended deck. Figure 1 illustratesthe tank design referred to in this paper. A failure in the primary containerbottom results in LNG liquid leakage into the tank bottom insulation. Dependingon the size of the leak, the outer tank bottom may be breached whenexposed to the cryogenic liquid at -161℃and LNG may be released into thefoundations.Typically, a leak problem on an LNG tank bottom manifests itself by lowfoundation temperature readings. When the carbon steel outer tank bottom isbreached, a gas leak is generally present at the outer tank base.Fig. 1.The 48,000 m3 LNG tank configuration.LNG tank integritySince the first LNG disaster caused by the brittle fracture of the Cleveland,Ohio, 3.5% Ni stainless steel LNG tank, in 1944, there has been a sustainedeffort in the LNG industry to improve the safety of storage tanks. On thewhole, inner tank construction materials, such as 9% Ni steel, have performedfairly well. In general, LNG tanks with a leak problem are subjected, dependingon the nature of the problem, to a strict follow-up pending permanent satisfactoryrepairs or immediate shutdown.In some cases, the confidence level in the repairs was not considered adequateand new tanks were built. This is the example of the two 150,000 m3LNG tanks on Das Island, UAE. One of the tanks developed a crack in thebottom penetration [2]. The replacement tanks were of the double integritytype, i.e., both the inner and outer tanks are capable of containing the cryogenicliquid. The provision of internal submerged pumps further eliminatedall tank penetrations below the liquid level. Most of the LNG tanks built inrecent years are of the double integrity type.Assessment of source and cause of low foundation temperatureThe first step in tackling a problem of this type is to effect an external inspectionof the tank for any indications of a problem, including checking forflammable gas and carrying out functional checks on the instrumentation toensure correct temperature readings.Thereafter, a comprehensive evaluation of the problem is carried out to determinewhat actions need to be taken:(a) Should the tank continue to be operated normally under close observation,pending eventual decommissioning for repairs?(b) Should the maximum operating level be reduced?(c) Should the tank be decommissioned immediately?(d) Can the repairs be effected without decommissioning the tank?Each leak problem determines its own requirements. For the tank referredto in this paper, it was concluded that the tank be scheduled for decommissioningto effect the necessary repairs.The nature of the problem did not lend itself to pinpointing the leak point.However, from the foundation temperature measurements shown in Fig. 2, itwas determined that the problem was confined to the bottom discharge nozzlesarea.A weighted fault tree, based on the following items, was developed to addressthe possible causes:(a) One of the fabricated discharge nozzles shown on Figs. 2 and 3 developeda crack.(b) The nozzle to inner tank floor weld failed.(c) The perlite insulation within the nozzle’s pit settled.(d) The inner tank floor plate or lap joints developed a crack.(e) The heating system failed or was inadequate.(f) Because of the bottom fill line penetration through the annular space,condensationof heavy ends may have formed on the outer tank bottom.Review of the operating history, checks on the heating system, the localizedlow temperature readings and external observations led to the conclusion that(a), (b) or (d) above was the cause of the low temperature readings.Fig. 2. Sample point temperature readings in foundations and on outer tank bottom (□) asaresult of an inner tank floor weld repair failure; (■) leak location after tank entry.Fig. 3. Discharge nozzles-crone-sectional view.Repair guidelinesRecertification of the LNG tank after repairs requires a strict control of therepair procedures:Every effort should be made to minimize tampering with the inner tank.Every step in the repair program must be preceded by thorough inspectionsand evaluations, in order to eliminate unnecessary work.The inner tank bottom entry and closure shall be conditioned by exactingprocedures including:- Marking and labelling each element removed.- Recording dimensions and orientations.- Making a model of the nozzles pit inclusive of all bracing and structural elementsfor training the repair crew.- Establishing welding procedures and qualifying welders.Control of handling loads during repairs and load distribution on the tankfloor during the entire duration of the decommissioning.Investigative work with the LNG tank in serviceThe LNG tank operated without any problems for approximately 12 years.After this period the foundation thermocouples began indicating low temperaturereadings under the discharge nozzles. The temperature dropped as lowas -79℃. A sample temperature record is shown in Fig.2.Externally, therewas no evidence of any problem.A survey around the tank outer ringwall andat the entry/exit of the heating and thermocouple cable conduits indicatedthere was no flammable gas present.Although the temperature readings varied over a few months, there were nomarked variations that could be correlated to changes in liquid head or vapourpressure inside the tank.Tests on all thermocouples indicated there were no malfunctions.Fig. 4.Foundation investigation.Since there was no external indication of icing, condensation, or other symptomsof a leak, it was decided to carry out the following.(a) A 25-mm diameter hole was drilled to over 90% of the depth of the outerringwall as shown on Fig. 4. The temperature was found to decrease with depth.At 1.10m depth the temperature was -2.5℃(b) Due to the rebar steel reinforcement in the outer ringwall, the drilling wasterminated and a trench 1 m deep by 1 m wide was carefully dug under theringwall. The tank foundations, consisting of a sandy substrate, were found tobe frozen inside the ringwall, but there was no evidence of any free ice formationor other indication of frost heave.The trench was terminated at approximately 2.4m from the outer tank shell,as shown in Fig. 4. The exposed heating conduits were found to be completelycorroded. The absence of any flammable gas suggested that the outer tankbottom was not breached.A 0.90m deep hole was drilled into the foundations, at the furthest point ofthe trench, indicated a temperature of -5.5℃at 0.50m below the tank bottom.A thermocouple was installed in this hole, so that the foundation temperaturecan be monitored during tank warm-up. The trench was temporarilybackfilled.Determination of the scope of repairsSince the exact cause of the problem could not be determined prior to thetank decommissioning, procurement of materials and tooling was based on theworst case, i.e., one of the discharge nozzles has failed. A quick turn-aroundrequires thatmaterials, equipment and repair procedures are available upontank decommissioning.The assumption of a discharge nozzle failure implies a significant repaireffort which requires:(a) Removal of the inner tank bottom plates over the affected area to gainaccess into the nozzles pit shown in Fig. 3.(b) Removal of the upper concrete slabs over the bracing in the nozzles pit.(c) Removal of the fibreglass and perlite insulation in the nozzles pit.(d) Removal of the steel bracing around the failed nozzle to permit repairs orreplacement.(e) As a contingency for frost heave damage or excessive thermal stresses onthe outer tank bottom, in the area directly under the leakpoint, provisions aremade to:●Remove the concrete slabs over the outer tank bottom for inspection.●Remove the cracked outer tank bottom plates.(f) Provide adequate Foamglas blocks for replacement in case the outer tankbottom failure extends outside the nozzles pit.(g) Effect the necessary repairs and testing, and restore the tank bottom to itsoriginal state.(h) The level of planned inspection and repair activities inside the tank led toopting for a lateral opening to permit entry and exit of materials and toolingwith dimensions exceeding the diameter of the lower manhole. The access portwas positioned and sized, so that it was at least one foot away from any buttweld of the inner and outer shells. Also, to get away from the high stress areaof the shell to floor weld joint, the opening was planned on the second courseof the inner shell. This led to making provisions for replacement plates to theinner and outer shells.Inspection upon tank entryInduced residual magnetism in 9% Ni steel makes the material difficult toweld. Because of this, Magnetic Particle Non-Destructive Testing was prohibited.Magnetic equipment was also not permitted inside the tank. The inspectiontechniques used consisted of Vacuum Box, Liquid Penetrant and SoapTest.Because the problem area was fairly well defined, the leak point was identifiedalmost immediately with the Vacuum Box: A weld repair of approximately25mm dia, on a floor plate was found to be the cause of the problem. Non-Destructive Testing over the affected area showed no other major defects orfailures. The discharged nozzles were checked internally with Liquid Penetrantand pressure tested to the equivalent of the maximum liquid level. Allwere found to be free of any defects.Due to the location of the leak point, it was not necessary to disturb theinner tank floor, or make a lateral access for materials and tooling. Tank entrywas effected through the lower manhole.Additional tests over the entire innertank floor and the two lower shell courses did not locate any other penetratingcracks. There remained, however, a question on the integrity of the outer tankbottom due to the excessively low temperatures recorded. The fact that thefoundation substratewas frozen may haveprevented free escape of leaking gas.After decommissioning, the tankbottom is free of flammable gas and thereforetesting for flammable gas is not a useful test.To test for the possibiity of an outer tank bottom leak, the trench under thetank was extended beyond the leak point as shown in Fig. 4. The sand andasphalt underlays beneath the outer tank bottom were removed, and the bottomsandblasted. Dye Penetrant, Soap Tests and visual inspection did not showany defects. Also the bottom plates were not corroded.Comments on weld defectThe leak was due to an inadequate weld repair in the middle of a floor platebetween the nozzle openings and the inner shell. This location was remotefrom the high stress area of the footer plate to shell weld-joint. The 2.28m×6.3mm thick plate was made of 9% Ni, Double Normalized and Tempered steel.The crack was confined to the periphery of the weld filler metal as shown inFig. 5. During the first 12 years of operation, the low temperature problem wasnot evident, suggesting that the crack developed fully at a later date.The bevelling of the plate surface preparation prior to weld repair is believedto account for crack closure with increasing liquid head, hence minimizing theeffect of the hydrostatic head on leakage rate. Thus, temperature variationswith increasing LNG level were not detected. Also, the leak point was locatedaway from the joints of the concrete slabs above and under the bracing of thenozzles pit, resulting in the small quantity of leaked LNG being spread over alarge area. This may have accounted for the outer tank bottom plate not beingbreached.Fig. 5. Inside-tank view of a weld repair leakage line.Backfill of trench under tank bottomThe confined space within the trench did not allow the backfill to be compacted.A multi-section, double-layered concrete backfill was used, as it metthe following criteria:(a) It must not significantly change the local support stiffness. This preventsintroducing a soft or hard spot into the foundations.(b) It must not produce localized relative settlement between the backfill andthe existing substrate, thus preventing the formation of voids.(c) The backfill must not transfer any bearing load to the heating elements.(d) The thermal conductivity of the backfill around the heating elements mustbe as close as possible to that of the installed sand underlay.(e) The backfill must have minimal shrinkage.In addition to the above, the asphalt underlay was reinstated over the exposedareas of the outer tank bottom.Safety considerationsTank entry after decommissioning, particularly under an air atmosphere,requires special safety measures. Although LNG tank purging principles arewell established [3,4], there has been a number of major accidents. Practicallyall accidents occurred several weeks after tank entry, when safety checks arerelaxed or not complied with. The Staten Island, New York, LNG tank explosionon February 19th, 1973 [5], illustrates this type of accident.For the LNG tank referred to in this paper, extensive safety provisions wereput in place inside and outside of the tank, and in the trench. The details ofthese provisions are outside the scope of this paper. However, it is thoughtrelevant to draw attention to the risk of asphyxia in the trench where nitrogenis used for purging. On this project, during replacement of the heating elements,it was noted that significant amounts of water was present in the conduits.Before any heating elements were installed, the conduits were dried bynitrogen purge. Because the heater conduits were perforated as a result of corrosion,the nitrogen purge was replaced with dry instrument air over the areaof the trench.The decommissioned tank was totally isolated from all process lines. ConclusionsAlthough 9% Ni steel has a good notch toughness at LNG temperature, theproblem reported herein highlights the need for a strict quality control on plates,repairs and field fabrication.A careful approach to investigative work on tank bottom leaks can eliminateunnecessary tampering with the inner containment. This approach minimizedor eliminates expensive and sometimes unacceptable full proving tests, priorto recommissioning.References1.Recommended Rules for Design and Construction of Large Welded, Low PressureStorageTanks, API Standard 620, Appendix Q, 7th edn., 1982, American Petroleum Institute.2.R.
