The existing hull structural monitoring system of the Aoka Mizu FPSO was extended in August last year with a time domain software tool able to provide valuable information regarding the integrity of the mooring lines.
Bluewater’s disconnectable turret moored Aoka Mizu FPSO had been operating at the Ettrick field, in the UK part of the North Sea, until the summer of 2016. It has since been contracted by Hurricane Energy for use in the Lancaster field, West of Shetland, in about 150 m water depth. The mooring system consists of three bundles with four lines each. Upgrade and life extension works to the vessel were carried out at Drydocks World, Dubai to make it suitable for long-term operations in a challenging environment such as the West of Shetlands. First oil was received in June 2019.

A DETAILED KNOWLEDGE
Following the success of the FPSO hull monitoring programmes developed over the last decades such as Monitas, Bluewater
decided to equip the FPSO with an extensive environmental and structural monitoring system. The new system was installed
during the upgrade at Drydocks World, Dubai. Its goal is also to validate predictions on several design choices and monitor the actual
fatigue life and load history of critical components of the FPSO.
