Guidelines for the Inspection and Maintenance of Double Hull Tanker Structures
This manual is sub-divided into eight chapters. The general design aspects of the double hull tanker are discussed initially indicating their origins from both strength and statutory considerations. This is followed by concentrating on specific areas within the structural arrangement that would be deemed to be more critical during the service life of the ship by reason of stress concentration, fatigue, corrosion, etc. Additional information is provided on damages to other double hull ships in service to complement this knowledge. Having defined the overall areas of concern, the manual addresses the means to protect the internal structures from corrosion and the necessary permanent access facilities that need to be incorporated into the ship at the time of build to ensure that adequate inspection, monitoring and maintenance can be carried throughout the service life of the ship.
