Application

Operating and Maintenance Manuals (OMM) being subject of this guideline apply to shell doors such as bow doors with the associated inner doors, side shell doors and stern doors with respect to the GL Rules I – Ship Technology, 1 – Seagoing Ships, 1 – Hull Structures, Section 6, H. and J., the IACS Unified Requirements S8, S9, S15 and S16 as well as SOLAS 74 as amended.

Exceeding common operating instructions, OMM shall provide full information to the ship's staff for maintaining and monitoring the sound condition of all elements of the shell door systems, relevant for the safety of the vessel. Detailed information on the procedures of maintenance and function tests are to be prepared.

The provision of the OMM is required for:

– Ro-Ro Passenger Ships – Ro-Ro Cargo Ships with bow door, and keel laying on or after 1996-07-01, if the bow door/inner door gives access to an enclosed superstructure

– Ro-Ro Cargo Ships with side or stern door, and keel laying on or after 1997-07-01, if the side or stern door gives access to enclosed spaces

The OMM is subject to Class approval. Submission to GL in 4fold (incl. drawings) is required for the distribution of the approved copies:

– on board

– owner's office

– GL-Head Office

– national administration (upon request)

The OMM must be prepared in a language understood by the users. If this language is not English, a translation into English is to be included.

In the following a framework of the conceptual layout is described. Deviations could make sense in case of the existing design and documentation concept, e. g. with door systems of simple design.
