LAUNCHING APPLIANCE - WINCH

APPROVAL CATEGORY: 160.115

APPROVAL GUIDANCE & INFORMATION: The Coast Guard technical requirements for lifesaving winches can be found in Title 46 U.S Code of Federal Regulations (CFR), Subpart 160.115, which references the IMO requirements in Chapter VI of the IMO LSA Code and the associated recommendations on testing (Resolution MSC.81(70)).

Before action is taken on any new or modified winch design, the Coast Guard will perform a pre-approval review to evaluate the design for compliance with all US and international requirements. Alternatively, plans may also be submitted to an accepted Independent Laboratory for pre-approval review, at the option and expense of the manufacturer.  A list of accepted Independent Laboratories for each approval series is available at the Coast Guard Marine Information Exchange (CGMIX) website.  (This link will take you to another USCG website.)

SUBMITTAL PACKAGE: To request pre-approval review from the Coast Guard, please submit the following to the address listed below:

To request pre-approval review from an Independent Laboratory, follow the Independent Laboratory's procedures for design review on behalf of the Coast Guard. Once the Independent Laboratory has completed preliminary design review, you must provide a copy of their assessment to this office to reserve a USCG approval number prior to scheduling prototype testing.  

Once the plans are determined to be satisfactory, the manufacturer will be authorized to build a prototype and conduct the required prototype testing and inspections under the supervision of a Coast Guard Marine Inspector.  If pre-approval review was conducted by an Independent Laboratory, forward a copy of their assessment to the cognizant Officer in Charge, Marine Inspection (OCMI) to schedule prototype testing. 

Following satisfactory prototype testing, submit the test reports (signed by a USCG Marine Inspector and/or Independent Laboratory surveyor, as required) and three sets of as built drawings to this office for review and issuance of Certificate of Approval. For prototype test reports, it is strongly recommended that manufacturers use the standardized format of MSC Circular 980.

If pre-approval plan review was conducted by an Independent Laboratory, please submit the following to the address listed below, in order to complete the application and receive a Certificate of Approval:

Please send the Submittal Package and other related information to:

Commandant (CG-ENG-4)
U.S. Coast Guard Stop 7509
2703 Martin Luther King Ave Jr SE
Washington, DC 20593-7509

Once the equipment has been approved by this office, it will receive Coast Guard Type Approval and a Certificate of Approval (COA). The COA will be issued for 5 years and may be renewed within 3 months of expiration with a statement from the manufacturer that the equipment is still being produced using the same plans and materials as originally approved and clear demonstration that all applicable production tests and inspections have been satisfactorily conducted and quality control procedures have been followed.

LIFEBOAT RELEASE MECHANISM (SOLAS)

APPROVAL CATEGORY: 160.133

APPROVAL GUIDANCE & INFORMATION: The requirements for release mechanisms* for SOLAS lifeboats and rescue boats are contained in Title 46 Code of Federal Regulations (CFR), Subpart 160.133. USCG approved release mechanisms under approval series 160.133 are primarily evaluated to the standards of the International Maritime Organization's (IMO) Resolution MSC.48(66), amended, entitled "International Life-Saving Appliance (LSA) Code", as referenced by the Safety at Life at Sea Convention (SOLAS), Chapter III. See the LSA Code Chapter IV/4.4.7.6 and 46 CFR 160.133-7 for the specific design and performance criteria.

Prototype test procedures are found in IMO Resolution MSC.81(70), amended, entitled "Revised Recommendation on Testing of Life-Saving Appliances". These IMO Resolutions, along with their amendments through 2010, are incorporated by reference in 46 CFR 160.133-7, and are published by the IMO in a handbook entitled, "Life-Saving Appliances, 2010 Edition", available for purchase from IMO publication distributors world-wide. See MSC.81(70), Part 1/6.9 “Release mechanism test” and 46 CFR 160.133-13 for the specific testing requirements.

Whether a new or modified design, before a manufacturer constructs, or even installs, a release mechanism, the Coast Guard will perform a pre-approval review to evaluate the design for compliance with all US and international requirements. Alternatively, plans may also be submitted to an accepted Independent Laboratory for pre-approval review, at the option and expense of the manufacturer.  A list of accepted Independent Laboratories for each approval series is available at the Coast Guard Marine Information Exchange (CGMIX) website.  (This link will take you to another USCG website.)

* Release mechanisms are also informally called “release hooks” which only refer to one component of the releasing system. The entire release mechanism system typically comprises a release handle at the helmsman station, hydrostatic interlock, cabling to/from the release handle, and the release hook(s) themselves.

SUBMITTAL PACKAGE: To request pre-approval review from the Coast Guard, please submit the following to the address listed below (see 46 CFR 160.133-9 for a complete description):

To request pre-approval review from an Independent Laboratory, follow the Independent Laboratory's procedures for design review on behalf of the Coast Guard.
