A Guide to Ship Repair Estimates in Man HoursBy
- Don Butler
- Don Butler
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.Don Butler has gathered the information in this book over more than twenty years in the repair field. He is a holder of the DTI Combined first class Engineers Certificate of competency for steam and motor ships and a Fellow of the Institute of Marine Engineers (F.I.Mar.E). He is also a Member of the Society of Consulting Marine Engineers and Ship Surveyors (M.C.M.S).

'This is an invaluable and rare little reference book written for those involved with costing shiprepairs. It is rare forproviding an independent maens by which repairs can be estimated without resorting to tariff rates published by individual shipyards. Invaluable because it is a very practical book containing only information necessary to fulfil the objective of obtaining a useful estimate....The format is simple. Information of the repairs is stated briefly. A table is then provided of the estimated manhours required for a particular job....This book will be a valuable tool for those involved with shiprepair. Those who would benefit in particular are superintendents and ship repair yards.' Marine Engineers Review, March 2002 'By referencing man hours rather than monetary value, the book is universally applicable and will be of extended long-term relevance. It will assist technical superintendents in compiling repair specifications with a pricing strategy, so they can build up costings for their planned repair periods...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 to be issued to the repairer.'
