Who has the authority to authorize the dismantling or removal of any MRG casing or its access openings?

The Engineer Officer is responsible for the oversight and management of engineering operations and maintenance within the naval vessel. This position includes the authority to make critical decisions regarding the maintenance and operation of machinery, including the Main Reduction Gear (MRG) system. Given the technical nature and potential safety implications involved with dismantling or removing an MRG casing or its access openings, such actions require a high level of expertise and responsibility that falls within the purview of the Engineer Officer. This ensures that safety, operational integrity, and procedural compliance are maintained during such operations.

The responsibilities of the other roles, while important, do not encompass the direct technical oversight needed in this specific scenario, making the Engineer Officer the most appropriate authority for such actions.
