A riding squad converts sea passage into repair time. Done well, a vessel arrives at her next port with the steel work closed out. Done badly, she arrives with a half-finished job, extra people to feed and a bill for both.

Scope it against the passage, not the wish list Start from the number of working days the passage actually gives — weather, watch routines and access to the space all subtract from it. A scope that needs fifteen working days on an eleven-day passage will not shrink; it will just end unfinished.

Send the consumables with the people Squads lose more time to missing consumables than to anything else. Electrodes, discs, gas, staging, blasting media, paint and PPE must sail with the team in the quantities the scope actually consumes, because nothing can be added at sea.

Agree who directs the work The chief engineer directs work on board — that has to be stated before the squad joins, along with hot-work permit routines, fire watch, access to spaces and the daily reporting line back to the office. Ambiguity there is where a good squad turns into an argument.

Close out before disembarkation Photographs, measurements, coating records and a signed job list at the disembarkation port turn the passage into something the owner can put in front of a surveyor — and something the next squad can build on rather than rediscover.
