Permit to Work
Permit to Work is the formal authorization process used to control hazardous, non-routine, or interacting work on board a yacht or during a yard period. In superyacht operations it sits inside the vessel’s safety management system, the yard’s control-of-work regime, or both. The permit does not replace competence or supervision. It records that the work has been defined, the risks reviewed, the controls agreed, and the job released by the responsible person before it starts.
OCIMF’s vessel inspection guidance describes a permit to work system as one that covers all areas of the vessel, addresses crew and contractor scopes, defines the work, identifies hazards, establishes controls, links related permits or simultaneous operations, requires authorization by responsible persons, communicates the controls to those involved, and ensures control over the return to normal operations. That framework matches how PTW is used on refit-heavy yachts with many concurrent jobs.
Typical yacht permits cover hot work, enclosed-space entry, electrical work, work aloft, diving, energy isolation, and tasks that can affect fire integrity, watertight integrity, or live machinery. During a yard stay, the permit system is one of the few tools that ties ship staff, contractors, and the yard into one visible control layer. It becomes especially valuable on a yacht refit where hotel operations, guest-sensitive areas, and technical work may overlap in tight spaces.
A permit only has value when the stated controls are real: gas checks are current, isolations are in place, boundaries are understood, and the job is closed properly once the system returns to service. Weak PTW discipline usually shows up through conflicting jobs, uncontrolled openings, unexpected energization, or work continuing after the conditions of the permit have changed.
