Not every repair needs a dry-dock. Understanding when afloat repairs, riding squads or a full docking is the right call can save significant off-hire time.
Afloat and voyage repairs
Many repairs can be completed while the vessel stays in the water, at a berth, at anchorage, or even underway using a riding squad. Afloat repairs avoid the cost and scheduling of a dry-dock and keep the vessel earning, which is why they are often the first option for mechanical, piping, electrical and many steel works.
When a dry-dock is required
Work below the waterline, such as hull plating, propellers, rudders, sea chests and underwater coatings, generally requires a dry-dock, as do many class-driven surveys. Planning the work list early lets the owner combine class items with other works in a single docking and minimise total off-hire.
Making the decision
The right approach depends on the scope, the vessel's class survey position, the trading pattern and the cost of off-hire. A repair coordinator who understands all three options, afloat, shore-supported and dry-dock, can sequence the work to keep the vessel out of service for the shortest possible time.
