Applicability: All release mechanism manufacturers, shipyards, shipowners and managers

IACS Unified Interpretation (UI) SC 267 introduces an important interpretation of the requirements for lifeboat release and retrieval systems contained in paragraph of the LSA Code.

Specifically, the UI provides: 

  • the appropriate corrosion tests to be applied to components identified in paragraph 4.4.76
  • the grade of stainless steels that should be used
  • an appropriate corrosion resistance test standard, and
  • the Pitting Resistance Equivalent Number (PREN) of the metals that should be used in a lifeboat to demonstrate compliance as a “material corrosion resistant in the marine environment without the need for coatings or galvanizing”. 

In addition, UI SC267 Rev. 1 (which will be implemented at the same time as UI SC 267) clarifies that lifeboat control cables which are covered with a sheath and installed inside the lifeboat and therefore not exposed to a corrosive environment are not subject to the requirements of the UI.   

What does this mean for me?

Manufacturers, shipyards, shipowners and managers will need to note and apply the following:

  1. All newly approved release mechanisms are to demonstrate compliance with UI SC 267 if the certificates are issued on or after 1 January, 2016.
  2. For release mechanisms that are already approved, manufacturers are expected to be compliant with the UI when the current certificates are renewed after 1 January, 2016.
  3. For release mechanisms that are already approved, but for which the manufacturer wants to amend the certificate during its validity, the implementation of the UI is as follows:
    • For modifications to items covered in the UI, compliance with the UI is compulsory.
    • For modifications to items not covered in the UI, compliance with the UI is not compulsory.
