What safety protocol must be strictly adhered to before commencing any maintenance work on a submerged tidal turbine?

The most critical safety protocol that must be strictly adhered to before commencing any maintenance work on a submerged tidal turbine is the complete Lockout/Tagout (LOTO) procedure to ensure the turbine is de-energized and cannot be restarted accidentally, along with confirmation of environmental conditions and clear communication protocols. The Lockout/Tagout (LOTO) procedure involves isolating the turbine from all energy sources, including electrical, mechanical, and hydraulic, and physically locking and tagging the energy isolation devices to prevent accidental re-energizatio....
