Afloat and riding-squad repairs — mechanical, piping, steel and electrical — scoped against the vessel's defect list.

Scope

• Mechanical — main and auxiliary engine overhauls, pumps, compressors, purifiers, heat exchangers, valve and pump reconditioning, alignment and chocking.
• Piping — renewal and repair of sea water, fresh water, fuel, hydraulic and steam lines, including prefabrication ashore to reduce time on board.
• Steel and welding — deck, hatch cover, tank and structural steel renewal, cropping and renewal to class requirements, carried out by qualified welders.
• Electrical and automation — motors and generators, switchboards, alarm and monitoring systems, cabling and fault-finding.

How jobs are run

• Work is quoted against the vessel's defect list, not against a generic scope. Where the list is long, we will separate what has to be done this call from what can safely wait, so the port stay isn't spent on items that could have run another voyage.
• Riding squads travel with the vessel where a job can't be completed in port. This keeps the ship trading while the work continues, and is usually the cheaper answer when the alternative is extending the port stay or arranging a second attendance.
• Where a scope grows after the vessel has berthed — which it often does once something is opened up — the practical question is whether the extra work still fits inside the existing stay. Answering that early is what avoids the expensive version of the problem.
