The Monitas JIP aimed to develop the added value of advisory monitoring systems for integrity management by in-depth analysis of measurements, exchange experience, provides software updates, support and training.

background

From the very beginning of offshore exploration it has been well-known that permanently moored offshore installations are continuously exposed to sea actions. Despite this knowledge many FPSOs are still suffering from fatigue damage. These failures often come as a surprise to operators because there are no hull integrity monitoring systems installed. In addition, industry records show that many structural monitoring projects have floundered because they did not provide effective data processing and interpretation tools. The Monitas Joint Industry Project has changed this situation. Within this project, an Advisory Hull Monitoring System (AHMS) has been developed and successfully implemented and tested for two FPSOs.

ADVISORY HULL MONITORING SYSTEMS

An Advisory Hull Monitoring System (AHMS) is an advanced hull monitoring system which includes software named OCTOPUS-Monitas. This software shows, explains and advises on fatigue integrity of FPSOs. It explains reasons for potential deviation of the actual fatigue consumption from design predictions and translates the monitoring data into operational guidance and advice in an easily understandable format. As a consequence it also provides the designers with feedback on the quality of their design tools. A forecast module with confidence bounds for future fatigue accumulation is included in the software.

MONITAS GROUP
In order to proceed with providing Monitas related services to the industry, a group for Monitoring Advisory Systems for offshore floating structures was initiated in 2014.

The group is aiming to further develop the added value of advisory monitoring systems for integrity management by in-depth analysis of measurements, exchange experience, provides software updates, support and training. Benefits for participants are that they are well informed on the possibilities to assess fatigue, up front cooperation with key players and benefiting from industry experience and developments. The Group started as a three years project after which it was evaluated. In April 2018 a second three years phase of the project will start. The Monitas Group allows new participants to join.
