MEASURES TO PREVENT ACCIDENTS WITH LIFEBOATS
 
Guidelines for developing "Operation and Maintenance Manual for a Lifeboat System"
 
Submitted by Japan
 
SUMMARY
Executive summary: This document proposes development of appropriate "guidelines for developing operation and maintenance manual for a lifeboat system" to prevent casualty with life boats
 
Action to be taken: Paragraph 12
 
Related documents: DE 46/9/7, DE 46/32, DE 47/5/3, DE 47/25 and DE 47/WP.9
 
Background
 
1 As mentioned at DE 46, Japan investigated the reports of specific casualties with lifeboats and considered that standardization of "operation and maintenance manual for lifeboat release gear systems" was one of the essential and immediate tasks of the Sub-Committee for preventing such casualties (c.f. DE 46/9/7). The Sub-Committee supported the proposal in general and noted the intention of Japan to submit the draft manual to DE 47 for consideration (c.f. paragraph 9.3 of DE 46/32).
 
2 At DE 47, Japan submitted "draft guidelines for developing operation and maintenance manual for on-load/off-load release gear system of lifeboat" (DE 47/5/3) and invited the Sub-Committee to consider the scope of guidelines for developing manuals. During discussions at plenary, it was agreed that such guidelines for life boat systems overall was preferable (DE 47/WP.9 paragraph 17).
 
3 The drafting group agreed that, to develop such guidelines, the following tasks are necessary:
 
.1 determination of the scope of the guidelines;
 
.2 consideration on items (table of contents) which will be included in the guidelines;
 
.3 consideration on requirements/precautions for developing such manuals; and
 
.4 development of example(s) of such manuals.
 
4 Then, Japan volunteered to further refine the draft guidelines submitted at annex to DE 47/5/3, taking into account discussions in plenary and in the drafting group, with a view to submitting it to a future session of the Sub-Committee. The group was of the view that such manuals are different from each other and that the requirements/precautions should not be too specific in detail and invited the Sub-Committee to endorse the group's action (DE 47/WP.9 paragraph 18).
 
5 The group recommended that the Sub-Committee invite Member Governments and international organizations to submit information and comments on the above-mentioned issues, including examples of such manuals, if possible, to DE 48, taking into account DE 47/5/3 (DE 47/WP.9 paragraph 19).
 
Draft guidelines for developing operation and maintenance manual for a lifeboat system
 
6 After the forty-seventh session of the Sub-Committee, Japan continued the work on these issues and prepared the draft guidelines for developing operation and maintenance manual for a lifeboat system as set out in the annex to this document for consideration by the Sub-Committee.
 
Important aspects on operation and maintenance manual for a lifeboat system
 
7 Based on the results of our investigation on casualties with lifeboat systems, it was concluded that the following aspects were important for such manuals to prevent misunderstanding of seafarers on operation and maintenance of lifeboat systems:
 
.1 collaboration of manufacturers of the lifeboat and the launching appliances;
 
.2 use of standardized wordings; and
 
.3 use of figures for explanation.
 
8 Regarding collaboration of manufacturers of the lifeboat and the launching appliances, manuals for a lifeboat and for its launching appliance are often separated, while a lifeboat and its launching appliances are used at once. In such cases, sometimes, different words are used for expressing one gear, e.g., release lever and release handle. Such variety of wording in a pair of manuals for a lifeboat and for a launching appliance may result in misunderstanding of seafarers. In view of this, consistency on expression in these manuals is important. It is preferable to incorporate these manuals into one comprehensive manual.
 
9 Use of standardized wordings is effective, not only for keeping wording consistent in a set of manuals, but also for familiarization of seafarers to the operation and maintenance of lifeboats and launching appliances un-experienced. Taking into account that seafarers often changes ships, it is important to use standardized wordings in manuals for various lifeboat systems.
 
10 Use of enough number of figures for explanation in a manual is also important to make the manual more user-friendly. In view of this, use of standardized pictograms or schematic diagram for indicating essential gears of lifeboats and their launching appliances are important to prevent miss-operation.
 
Information on maintenance contained in a manual
 
11 At the meeting in Japan on the draft guidelines, the information on maintenance was discussed. Then it was consequently decided that detailed information on maintenance is not necessary in the manual by the following reasons:
 
.1 revised regulation III/20.3.1, which requires that maintenance of life-saving appliances shall be carried out based on the guidelines developed by the Organization, will enter into force on 1 July 2006;
 
.2 in accordance with the guidelines, i.e., MSC/Circ.1093, it is required that all inspections, servicing and repair, other than weekly and monthly ones, should be conducted by the manufacturer's representative or a person appropriately trained and certified by the manufacturer for the work to be done; and
 
.3 the scope of on-board manual can therefore be limited for weekly and monthly works in regard to maintenance.
 
Action requested of the Sub-Committee
 
12 The Sub-Committee is invited to consider the guidelines for developing operation and maintenance manuals for lifeboat systems and take action as it deems appropriate.

ANNEX
 
DRAFT MSC CIRCULAR
 
Guideline for developing "operation and maintenance manual for a lifeboat system"*
 
1 The Maritime Safety Committee, at its [eightieth session (date)], taking into account the number of casualties with lifeboat systems, further recognizing the need to improve manuals for operation and maintenance of lifeboat systems, and having considered proposals by the 48th session of the Sub-Committee on Ship Design and Equipment (DE), approved the Guideline for developing "operation and maintenance manual for a lifeboat system", as set out in the annex.
 
2 Member Governments are invited to bring the annexed Guidelines to all the parties concerned for their application, as appropriate.
 

* The draft guidelines were developed by the National Maritime Research Institute (NMRI), the Research Institute of Maritime Engineering (RIME) and the Nippon Kaiji Kyokai (NK) based on the model manual developed by Japan Ship-Machinery Quality Control Association (JSMQA) with the co-operation of lifeboats and davit manufacturers.

Guideline for developing "operation and maintenance manual for a lifeboat system"
 
1 Scope of the guideline
 
 Seafarers often change ships and sometimes are not familiar with the lifeboats on their ships. Casualties with lifeboat systems are often caused by the poor understanding of the lifeboat systems, especially on release gear systems. User-friendliness of manuals for lifeboat systems is, therefore, important to prevent casualties with the systems.
 
 The purpose of these guidelines is to provide the precautions for developing user-friendly manuals for operation and maintenance of lifeboat systems including launching appliances to make such manuals easy to understand. Manufacturers for lifeboats and for launching/recovery appliances are invited to make manuals easy to understand, taking into account these guidelines.
 
 These guidelines are not applicable to making emergency instructions required by regulation III/8, operating instructions such as posters and signs required by regulation III/9 of SOLAS Convention and other brief instructions for operation of lifeboats.
 
 These guidelines are for seafarers and do not refer to the detailed procedure for maintenance works, because all maintenance works, other than weekly and monthly ones, should be conducted by the manufacturer's representative or a person appropriately trained and certified by the manufacturer for the work to be done in accordance with MSC/Circ.1093.
 
2 Collaboration of manufacturers of the lifeboat and the launching appliances
 
 Manual for a lifeboat system including launching appliance should be developed under the collaboration of manufacturers of the lifeboat and the launching appliance and preferably be one rather than separated. At a minimum, use of difference words for the same gear/parts of the lifeboat system should be eliminated by the collaboration of manufacturers of the lifeboat and the launching appliance to prevent misunderstanding by seafarers. Hereafter, a manual for a lifeboat system including launching appliance is referred to.
 
3 Contents of a manual for lifeboat system
 
3.1 Items to be included in a manual
 
 Operation and maintenance manual for a lifeboat system, at a minimum, should include the following items:
 
.1 Explanation on the outline and the specification of the lifeboat system;
 
.2 Explanation on the structure and mechanism of major parts of the lifeboat system including release gear systems;
 
.3 Operation of the lifeboat system; and
 
.4 Maintenance and inspection of the lifeboat system.
 
3.2 Outline of a manual
 
 It is recommended to develop a manual for a lifeboat system consisting of the following:
 
1 General description on the whole lifeboat system
 
2 Launching operation
 
3 Recovery operation
 
4 On-load/off-load release gear system
 
5 Maintenance
 
3.3 Explanation on the structure and mechanism
 
 The structure and mechanism of the lifeboat system, in particular the on-load/off-load release gear, should be explained using figures and perspectives, preferably three-dimensional. In addition, representative procedures during the operation of the release mechanism should be described sequentially.
 
3.4 Operation of lifeboat system including release gear systems
 
 Operation of the lifeboat system should be shown in accordance with the following instructions:
 
.1 Flow of the operation should be explained;
 
.2 Detail of operation should be explained with figures. Operation and relevant movement of the parts of the release gear should be described with illustration/photo, preferably using marks and arrows;
 
.3 Hazards, precautions and notes should be identified with specific marks;
 
.4 In the explanation of "on-load release operation", it should be emphasized with the following wording that the operation makes the lifeboat dropped:
 
"This operation drops the lifeboat and may cause fatal casualty;"
 
and
 
.5 In the explanation of "resetting operation", it should be emphasized with the following wording that the incomplete resetting may lead to drop the lifeboat:
 
"Incomplete resetting may cause dropping of lifeboat resulting in fatal casualty."
 
3.5 Maintenance and inspection
 
 The items for weekly and monthly inspection/maintenance and other inspection/maintenance should be clarified.
