The Petroleum Protection Authority Norway (PSA) has issued a report on its investigation into Equinor’s challenges with the development of the long term FPSO for its Johan Castberg area. The floating generation, storage and offloading (FPSO) facility is getting crafted by Singaporean yard Sembcorp Maritime, and the job has been dogged by really serious challenges with weld excellent. In a statement, PSA said that major breaches of Norwegian laws have been discovered and Equinor has been issued with an get requiring adjustments to its excellent-management procedures.

Johan Castberg is positioned in the Barents Sea to the northwest of Hammerfest, over the Arctic Circle, and it will be developed with an FPSO. Equinor issued a agreement for the building of the hull and living quarters to Sembcorp in late 2017.

The PSA learned of welding problems in design through the initial 50 % of 2020 of weld-quality faults in the Johan Castberg FPSO hull. The improper welding calls for a 100 p.c re-inspection of the vessel’s welds and comprehensive fix and rework.

PSA introduced an investigation into how the difficulty unfolded and was permitted to persist, and it determined multiple challenges.

Initially, Sembcorp Maritime is principally a repair yard, not a new development lawn, and it was the initially time that Equinor had worked with Sembcorp on a newbuilding job. The deal specified that fabrication and assembly ought to consider place at Sembcorp’s Tuas Boulevard Garden, but in the course of the 1st development yr, fabrication of the dwelling quarters and some of the hull modules was transferred to three other locations.

Second, Equinor’s follow-up and oversight effort and hard work was carried out with a lean job corporation, even while Equinor was informed of “high-quality, capability and knowledge issues” at Sembcorp. As soon as work was beneath way, Sembcorp concentrated on attaining building milestones and kept the project timeline on keep track of.

Essentially, PSA said, “welding expertise and excellent manage at SCM ended up inadequate.” Equinor didn’t handle this concern early enough, according to PSA, and allegedly did not be certain total implementation of the project’s governing inspection and examination strategy. Various acknowledged and determined hazards were left unresolved about a extended period, and the seriousness of some of these hazards greater.

As a consequence, welding repairs will hold off the FPSO’s completion by about a calendar year, and PSA believes that some deficiencies are now permanently baked into the facility’s composition.

“Inspection and repair are unable to compensate for insufficient welding knowledge. Complete inspection of all welds is impractical, nor is it technically feasible for inspection to identify reliably all flaws which may be existing. Wherever particulars and spots are accessible for inspection and repair service, some increase will be knowledgeable in the predicted need for maintenance and repair service. Inaccessible facts and spots will have a decreased structural reliability than would have been the circumstance if the welding had been carried out by proficient staff,” wrote PSA.

As a remedial measure, PSA has ordered Equinor to evaluation and improve its programs for determining chance and taking care of suppliers. It has issued a deadline of Oct 1 for the overhaul.
