1. Background
1.1 The Maritime Safety Committee at its 89th session adopted MSC Resolution 317(89), introducing new requirements under SOLAS regulation III/1.5 for Lifeboat Release and Retrieval Systems (LRRS). The requirements apply to on-load release mechanisms installed on all ships, i.e. both new and existing cargo and passenger ships. The Committee also adopted MSC Resolutions 320(89) and 321(89) which contain amendments to the Life Saving Appliances (LSA) Code requirements and for the testing and approval of LRRS.
1.2 In addition, the Committee approved circular MSC.1/Circ.1392 ‘Guidelines for Evaluation and Replacement of Lifeboat Release and Retrieval Systems’. Existing systems that do not comply with the revised LSA Code in accordance with SOLAS regulation III/1.5, are to be replaced no later than the first scheduled dry-docking of the ship after 1 July 2014, but in no case later than 1 July 2019.
1.3 In accordance with MSC.1/Circ.1392, the MCA strongly urges that all UK vessels fitted with lifeboat on-load release systems should be equipped with FPDs pending the evaluation of the systems for compliance with the requirements of the revised LSA Code. FPDs should be fitted in accordance with MSC.1/Circ.1327 ‘Guidelines for the fitting and use of fall preventer devices (FPDs)’.
2. Using an FPD
2.1 On each UK vessel, FPDs in accordance with MSC.1/Circ.1327 should be employed for each existing lifeboat release and retrieval system until the system is:
.1 Evaluated and found compliant in accordance with MSC.1/Circ.1392; or
.2 modified then evaluated and found compliant in accordance with MSC.1/Circ.1392; or
.3 replaced by a new lifeboat release and retrieval system.
2.2 The MCA recognises the responsibility of the Master to make decisions with respect to safety, as set out in the ISM Code 5.2, and consequently the use of FPD should be advocated by the ship Owner/Management Company and Master. In such cases procedures for use, inspection and maintenance are to be available and documented in the ship's Safety Management System (SMS) and training documents.
2.3 Subject to 2.2 above, the professional judgement of the Master is necessary in deciding the occasions and circumstances when FPDs are used. However, the FPD manufacturer’s limitations for use should be taken into account when making this decision.
2.4 Decisions relating to the fitting and use of FPDs should be documented in the vessel’s SMS and training manual. Where a different procedure is followed during routine drills compared with an abandon ship situation, this should be clearly described.
2.5 UK Port State Control officers should rely on the ship’s Master, SMS and training documents as a guide to the individual vessel’s operations regarding the fitting and use of FPDs.
2.6 In the event that an FPD cannot be fitted, then other mitigating safety measures should be taken such as those in MSC.1/Circ.1326 “Clarification of SOLAS Regulation III/19” whereby assigned operating crew should not be required to be on board lifeboats during launching. In such cases procedures are to be available and documented in the ship's Safety Management System (SMS) and training documents.
2.7 The guidance contained in this document should be followed on-board all UK vessels fitted with lifeboat on-load release systems by their next Safety Equipment Survey.
3. Type approval and Modification of LRRS to Accommodate an FPD
3.1 No modification of an LRRS or a lifeboat on-board a ship can be made, unless the Notified Body authorised to carry out the approval under the Marine Equipment Directive (MED) Regulations has agreed the change. Only the manufacturer of the equipment may make proposals for changes to their equipment. Any unauthorised modifications to either the LRRS or lifeboat will be seen as a change to the equipment and, subsequently, its compliance to the LSA Code, resulting in invalidating the approval and requiring the equipment to be re-tested and approved.
3.2 Where changes involve modifications to individual type approved components of the system such as an on-load release mechanism, the manufacturer should contact the Notified Body that approved the equipment, to verify that the changes are acceptable, and if any additional tests are required for the equipment. Where changes are made that have been agreed by the Notified Body, they must be fully documented in the technical file.
3.3 For information on the approval of marine equipment and Notified Bodies appointed by the United Kingdom, Merchant Shipping Notice (MSN) 1734 should be consulted. For pre MED equipment approved by a Nominated Body or the MSA as detailed in MSN 1735, the MCA should be contacted for advice.
3.4 The MCA will not approve the modifications made to an on-load release mechanism in order to fit an FPD. This approval must come from the Nominated Body who has previously approved the equipment, having been asked to do so by the manufacturer.
4 Fitting FPDs to the Hook Assembly Hanging-off Arrangements
4.1 The LSA Code requires the minimum strength for the hanging-off arrangement to be the mass of the lifeboat when loaded with its full complement of fuel and equipment plus 1000 kg. If the hanging-off arrangement is designed to this minimum requirement, this may not be suitable for the attachment of a strop type FPD when the lifeboat is fully loaded with its occupants. The possible shock loading of the boat in the event of an inadvertent release could result in much higher dynamic load than the hanging-off arrangement is designed for, causing a subsequent failure.
4.2 For strop type FPDs attached in this way, the lifeboat and davit manufacturer should be contacted to ensure that the fixing of the FPDs will be safe in the event of an inadvertent release, and under which anticipated loading conditions of the lifeboat such an arrangement is permitted. The decision to fit an FPD in this way ultimately lies with the ship Owner/Management Company, who have responsibility to ensure a safe system of work.
5 Consideration of vessel type
5.1 Those conducting training drills and drafting ISM Code procedures should take into account that with certain types of ship such as oil, gas or chemical tankers it may not be possible to use an FPD in an abandon ship situation where the release mechanism of the device is not inside the lifeboat. In such cases, the Master should take this into account when considering when an FPD should be fitted to the lifeboat. Where a different procedure is followed during routine drills compared with an abandon ship situation, this should be clearly described in the ISM Code documentation and training manual.
5.2 On certain types of ship such as passenger vessels, dependant on the Master’s decision under paragraph 2.3, the number of FPDs carried on-board need not necessarily be the same as the total number of on-load release mechanisms fitted.
5.3 If the vessel type precludes the fitting of an FPD, such as on vessels using fire protected lifeboats, then other mitigating safety measures should be taken as per paragraph 2.6
