IMO Hook Regulations

At the 89th session of the Maritime Safety Committee (MSC 89 - May 2011), the IMO adopted amendments to SOLAS Chapter III and the LSA Code, as well as related Guidelines for the Evaluation of Existing On-load Lifeboat Release and Retrieval Systems (LRRS). These adopted requirements apply to On-load Lifeboat Release gear systems of existing lifeboats requiring that these systems will have to comply with the guidelines of IMO Circular MSC.1/Circ.1392 

LR Guidance Note on Lifeboat Release and Retrieval systems – new IMO regulations can be found  here.

Frequently Asked Questions on the latest hook regulations

Q: Which new LSA Code requirements apply to existing ships and which ones apply to new ships?
A: Existing ships: Revised Chapter IV sections to applies to existing release gear systems fitted. New ships: built on or after July 1, 2014, release gear systems have to comply with the revised LSA Code (complete section

Q: To which requirements is the PALFINGER MARINE SeaCure release gear system complying?

A: The LHR M1 release gear systems are complying to the latest requirements for existing lifeboats and the SeaCure LHR M2 release gear systems are complying to the latest requirements for both existing and new lifeboats.

Q: Is it necessary to fit Secondary Safety Systems (SSS’s)?

A: There is no mention of SSS’s in MSC89/3/4. However, during the working group discussions at DE55 the use of such arrangements was strongly supported by various NGO’s. There are indications that some customers will require (demand) such an arrangement in addition to the regulations. This is why PALFINGER MARINE has incorporated this into their hook design as an additional option.

Q: What does this mean for ship owners?

A: Ship owners should identify the types of release gear systems on their vessels and verify if their release gear systems are in compliance with the new hook regulations (revised LSA Code sections to This information can either be obtained from the manufacturer of the release gear system (preferably) or by checking the IMO GISIS list on the internet.

If found not to be compliant than the release gear system needs to be modified or replaced no later than the next scheduled dry-dock after the 1st of July 2014 but no later than the 1st of July 2019.

Every release gear system which is compliant (or compliant after modification) should be subject to an one-time follow-up overhaul examination according to annex 1 to the Measures to prevent accidents with lifeboats (MSC.1/Circ. 1206/Rev1) by the manufacturer or one of their representatives.

Q: Which release gear systems of PALFINGER MARINE are currently mentioned on the IMO GISIS list?
A: The complete LHR M1 and SeaCure LHR M2 release gear range are mentioned on the IMO GISIS list. These release gear systems are either “compliant after modification” or “fully compliant”; this depends on the type of release gear system.
