505 - 01/07 - Lifeboat release gear mechanism - Worldwide
The examination has revealed that although the release handle was secured, i.e. the safety pin inserted, the release gear mechanisms were not fully reset. As a result, the hooks were not locked in place prior to the recovery of the lifeboat. The design of the SRS-37 type release gear mechanism made it such that it is possible to secure the release handle in the closed position without the hook being properly reset, hence giving the crew members a false sense of security.
The SRS-37 type release mechanism has been out of production for many years and an improved design has been produced since. However, according to the manufacturer, approximately 500 lifeboats with this type of release gear mechanism were fitted on ships operating worldwide.
Transport Canada are making recommendations to Port State Control Authorities that inspections should be undertaken on all ships equipped with the SRS-37 type release gear mechanisms and that the ability of the ship's crew to safely operate the release mechanism be verified accordingly.
