During this process manually brake.Check the reliability of the brake system.(4)One side anchor is to be hoisted. During hoisting process, average speed of hoisting anchor to bemeasured and recorded. (by measuring No.2 and No.3 shot of chain ) , The average speed is not less than 9m/min. Then hoist the anchor up to bell mouth with windlass.底图总号旧底图总号2.3.2 The report on chemical analysis and low calorific value to be submitted before this test.2.3.3 The ship should go straightly as possible during the F.O. consumption measurement.2.3.4 The measured F.O. consumption should be corrected according to the actual calorificvalue and ambient conditions, then be offered to owner for reference. (See Table M-6)2.4 M/E shaft power to be measured when F.O. consumption is measuring.II-3.M/E M.D.O. & H.F.O. changeover testM/E M.D.O. & H.F.O. changeover test to be executed as follows:M.D.O. --- H.F.O.(before M/E operating test for adjustment)H.F.O. --- M.D.O.(after M/E load test)II-4.Measurement of M/E lowest steady revolution(See Table M-7)M/E is adjusted to the lowest steady revolution by reducing revolution progressively atwhich the engine keep running for 5 minutes. Record the revolution of M/E andturbocharger, the graduation of the maneuvering handle and M/E fuel oil pump.Turnrudder angle to hard portside (35degree), observe change of the course.II-5.M/E reversing test(See Table M-8)M/E reversing test should be carried out while the engine running at the lowest steadyrevolution. The time for reversing should not be more than 15 seconds. The testincluding ‘ ahead –astern’ and ‘astern –ahead’ is not less than 3 times.II-6.Test for composite boiler (exhaust gas section) (See Table M-9)6.1 During M/E load test at NCR, the measurement of the evaporation of the compositeboiler (exhaust air section) to be conducted for one hour by flowmeter arranged at thedelivery side of the feed water pump. During evaporation test, composite boiler(oil-fired section) should not operate and the feed water to be kept stable.6.2 The soot blower of boiler to be tested.6.3 the safety valve popping test: Opening pressure of safety valve: 0.8 MPa6.4 Pressure accumulation test(The items tested at the mooring test stage will not be triedagain)The boiler pressure is not to rise more than 0.954 Mpa (6% above the maximum allowable working pressure) when the steam stop valve is closed under full firing condition for duration of 15 minutes. During this test no more feed water is to be supplied than that necessary to maintain a safe working water level.底图总号旧底图总号II-7.F.W. generator test (See Table M-10)7.1 During M/E NCR condition, F.W. generator to be running for one hour utilizing thewaste heat in the jacket cooling fresh water from M/E. Record the parameters asfollows:a)Vacuum and temperature of evaporation chamberb)Temperatures of cooling fresh water inlet and outletc)Temperatures of sea water inlet and outletd)Salinity in the distilled watere)Capacity(not less than 25 m3/24h,at NCR)f)Delivery pressure of sea water ejector pumpg)Delivery pressure of ejector7.2 In condition of voyage at low speed, F.W. generator to be running for function test withsteam(if some F.W. in outlet the test finished ).II-8.Shafting torsional vibration measurementThe test to be carried out from M/E lowest steady revolution to 91.0 r/min at intervals of5 r/min, and from 91.0 r/min to M/E lowest steady revolution at intervals of 5 r/min.Example: lowest steady revolution→30→35→40→45→55→60→65→70→75→80→85→91 r/min→lowest steady revolution。
