Don Butler has compiled an invaluable list of the man-hours required for ship repair estimates. All ships must undergo regular dry-docking for examination by a third party surveyor; this is a mandatory requirement for ships which ply their trade on either world wide or coastal area basis. This dry-docking period is usually used as a time to carry out known damage repairs, cleaning and painting, upgrades and regular machinery overhauls. The author provides estimates for all situations which may arise, enabling the repair superintendent to anticipate costs, and therefore to prepare an accurate repair specification well in advance, for issue to the repairer.
