In-Service Monitoring

In-Service Monitoring


Validation of computational tools against full scale data is essential to confirm that the tools are performing effectively. CRS has a maturing crop of research tools, for example PRECAL-R, STRUC, COGNAC, but whilst there have been some validation exercises, CRS has not embarked upon an extensive in-service monitoring campaign since the Margrethe Maersk programme in the 1990s (SMACS WG). A one year pilot study to investigate the requirements is therefore timely and will run through the 2012 calendar year.


Planning for a long term measuring campaign of some 5 or 6 years is required. The Pilot Study aims in particular to work with the CRS workgroups and chairmen to establish current and future data requirements. This could include motion and load monitoring to measure flexible modes of vibration, slamming and whipping detection, manoeuvring performance, powering and emissions data, propeller and shaft loads, and specialised wave measurement.

The pilot group also aims to identify a candidate ship or ships to host monitoring systems – CRS members include shipbuilders and operators. Working with CRS partners experienced in monitoring the group will identify appropriate technologies to achieve the required measurements and prepare a costed specification for the instrumentation, logging and data archiving systems.

Expected Results

The group will present a proposal at the 2012 CRS Annual General Meeting for a full workgroup, tailored to the needs of CRS research, for long term In-Service Monitoring with one or more ships
