Who is the Authorizing Officer for an equipment tagout for Engineering while underway?

The Authorizing Officer for an equipment tagout for Engineering while underway is the Engineering Officer of the Watch (EOOW). The EOOW is responsible for the overall operational integrity and safety of engineering systems on board a ship during its watch. This position entails ensuring that all equipment is safe to operate and that proper procedures are followed during maintenance and repair work.

When it comes to tagouts, the EOOW has the authority to approve and manage the tagging out of equipment, which prevents the accidental operation of machinery that is undergoing maintenance. This is crucial for the safety of personnel and the proper functioning of engineering systems. The EOOW is trained and designated to make decisions regarding engineering plant operations, including initiating and managing tagout procedures effectively while the vessel is underway.

The other roles listed, while they have their own responsibilities, do not possess the specific authority required for equipment tagouts in the engineering context.
