The Ship Structural Integrity Information System (SSIIS) project examines the development of a computerized information system that assists operators in the structural management of tank ships. The integration of information offers many advantages in the in the life cycle management of marine structures; supporting inspection planning, recording inspection results, designing repairs and analyzing failure trends. Reengineering is the redesign of existing information and work flows using information technology and organizational change. This report examines the reengineering of the structural inspection, maintenance and repair process to improve the integrity and quality of operating ships structural systems. This process is detailed and a prototype developed to demonstrate the applicability of these improvements.
