Cost effective inspection and structural maintenance for ship safety and environmental protection throughout its life cycle
For oil tankers to be more environmentally friendly along their life cycle, IMO has set forth a condition assessment scheme "CAS" for single hull tankers and is now working to develop a similar type of codefor double hull tankers, which involve huge amounts of measurement information. Performing thoseinspections efficiently requires processing measurement information on a real time basis, resulting incost savings because fast assessment of the ship condition and decision-making could be done while theship is still in the dock for maintenance.Measurement information consists of thickness measurements, visual assessment of coating and cracksdetection. In the existing situation, because there is no standardization of data, it is recorded manuallyon ship drawings or tables, which are very difficult to handle. Measurement information takes a longtime to report and to analyse, leading to some repairs being performed at the next docking of the ship.The system to be developed in this project includes such innovative features as: development of a simplified andflexible ship electronic model which can be refined to fit the needs of inspections, addition of measurementinformation in this ship model, automatic updating of the measurement information in the ship model, integrationof robotics, easy handling of measurement information using virtual reality, immediate worldwide access. Systematic comparison and consistency checks of measurement campaigns will trigger electronic alerts. Repairdecisions and residual lifetime of the structure will be calculated with modern methods of risk based maintenance modelling, with the interesting feature that the model will be updated after each measurementcampaign. The system to be developed is applicable to any ship type, but, due to the current focus on tankers and bulkcarriers, these ships will be used as the main case studies.
