This book highlights the relationship between independent and dependent ship repairing variables of various combinations under linear and nonlinear form using actual data collected from shipyards. Independent variables refer to age, deadweight, cubic number, principal dimensions, and type of ships. Dependent variables refer to repairing time, docking time, repairing labor, docking labor, hull blasting renewal area, hull painting renewal area, pipe renewal length, structural steel renewal weight, and structural steel renewal locations. Mathematical models are developed involving appropriate variables using multiple linear regression analysis technique for different combinations of variables of ship repair. Adequacy of models is tested using statistical parameters like coefficients of multiple determination and F statistic (calculated and tabulated). Also, validation is presented to determine the deviation of model value from the observed value and their statistical parameters to justifythe adequacy of the respective estimate models. The book also emphasises the importance of managing the labor force, reliable data collection and an effective management information system to manage this as well as keeping control of on-going repair contracts.

George began his career as a shipyard apprentice, gaining a BSc in Naval Architecture during this time. His early career was project managing shipyard developments mainly in North East England. He spent three years managing shipbuilding research and development at British shipbuilders, followed by work in a major international consultancy, advising private and public shipbuilders and governments. He became Technical Director and also completed an MBA. George ran his own shipyard consulting company, also developing management information software for shipbuilding and shiprepair. He joined Newcastle University, where he was awarded a chair as Professor of Shiprepair and Conversion, retiring in 2012. George remains active in teaching and consultancy in shipbuilding and repairing.
