MI-01, 8/06 REPUBLIC OF Marine Notice THE MARSHALL ISLANDS No. 2-011-41 OFFICE OF THE MARITIME ADMINISTRATOR 11/11 TO: ALL SHIPOWNERS, OPERATORS, MASTERS AND OFFICERS OF MERCHANT SHIPS, AND RECOGNIZED ORGANIZATIONS SUBJECT: Procedure for Sea Trials and Demonstrating Compliance with SOLAS Regulation II-1/28 and II-1/29. References: (a) SOLAS 74/88 Regulation II-1/28 (b) SOLAS 74/88 Regulation II-1/29 (c) IMO Resolution MSC.137(76) (d) IMO Assembly Resolution A.601(15) (e) Unified Interpretation SC 246 (June 2011) (f) MSC/Circular 1053 PURPOSE: The purpose of this Notice is to convey the policy position of the Republic of the Marshall Islands (RMI) Maritime Administrator (the “Administrator”) on SOLAS Regulations II-1/28 and II-1/29 on Sea Trials, for the benefit of all parties involved (owner, designer, builder and Recognized Organizations (ROs)), due to both regulations containing expressions which are open to interpretation. APPLICABILITY: This instruction applies to RMI passenger ships and cargo ships. REQUIREMENTS: 1.0 Full Load Sea Trials 1.1 Noting that during trials of some vessel designs it is impracticable to demonstrate the steering capability and stopping abilities of a vessel at the deepest seagoing draught, i.e. “full load”, the sea trials should be conducted as close as possible to the deepest seagoing draught as feasible, and, where it is safe to do so, should consider using floodable holds. 1.2 Drawing from paragraph 2.1.3.3 of MSC/Circular 1053, it is the Administrator’s position that “where trials are conducted in conditions other than full load…..it rests with the designer/owner to demonstrate compliance at the final full load condition.” 11/11 2 of 3 2-011-41 Republic of the Marshall Islands 1.3 As a way of demonstrating compliance, the Administrator encourages entities involved to apply paragraph 6.1 of Resolution MSC.137(76), which reads as follows: “6.1. In case the standard trials are conducted at a condition different from those specified in paragraph 5.2.3 [full load (summer load line draught), even keel condition], necessary corrections should be made in accordance with the guidelines contained in the Explanatory notes to the Standards for ship maneuverability, developed by the Organization.” 2.0 Stopping Ability 2.1 SOLAS Regulation II-1/28 uses the term “sufficient power for going astern.” To meet this requirement, the Administrator accepts the performance specified in paragraph 5.3.4 (Stopping ability) of Resolution MSC.137(76) and recommends the owner, designer, builder and RO of a vessel be guided accordingly. 2.2 Paragraph 5.3.4 reads as follows: “Stopping ability - The track reach in the full astern stopping test should not exceed 15 ship lengths. However, this value may be modified by the Administration where ships of large displacement make this criterion impracticable, but should in no case exceed 20 ship lengths.” 2.3 For unusual cases where the ship is a large displacement vessel and the predicted stopping distance exceeds 15 ship lengths, the RO should use its experience with such designs and propulsion arrangements to determine a suitable stopping distance which is no more than 20 ship lengths. 3.0 Maneuvering Data 3.1 A footnote of SOLAS Regulation II-1/28 refers to Resolution A.601(15). The Administrator requires vessels to have adequate maneuvering data for safe navigation and pilotage. This data is to be on board and available to navigators on the bridge. As a means of achieving this requirement the Administrator encourages the entities involved to follow the formats prescribed by Resolution A.601(15). 3.2 The Administrator recognizes that a period of time may be needed after sea trials in order to calculate the final maneuvering data. Therefore, the RO is permitted to allow a period of up to three (3) months for completion of calculations and subsequent availability of the data on the bridge. In the interim period provisional data should be available and carry a clear warning to navigators of its provisional status. 4.0 Steering Capability 4.1 Paragraph 3.2 and 4.2 of SOLAS Reg.II-1/29 use the term “capable of putting the rudder over.” To show compliance with this requirement, it should either be demonstrated at sea trial with the ship at its deepest seagoing draught and running ahead at maximum ahead service speed, or by one (1) of the following methods:
