Varg is a Floating Production, Storage and Offloading (FPSO) unit owned by Altera Infrastructure. She is normally moored at an offshore oilfield where she is connected to an oilwell, processing the well stream into crude oil and gas. Generally, FPSOs shall stay at site during the whole life of the oilfield without being disconnected or removed from the mooring system. Consequently, inspections have to be performed on-site and under continuous operation. Survey “campaigns” are therefore developed, that minimize operation downtime across multiple vessels.
The primary concern of tank surveys, or inspections, is to ensure that there are no cracks, corrosion or other issues that can compromise safety. Surveys are carried out together with classification societies such as DNV, which must be represented on-site together with other inspection personnel. Whilst safety is of paramount importance, surveys are also expensive. Finding new technologies that maintain or improve safety while reducing cost, is therefore always interesting.
In partnership with DNV and Altera, ScoutDI performed a range of inspections and tests onboard Varg in Skipavika, a harbour terminal in Norway. The task was to demonstrate non-entry inspection and live remote participation. ScoutDI, DNV and Altera were represented on-site and at Altera’s offices in Trondheim, participating remotely.
