Steady demand for AoCs



Five new mobile units received an AOC from the PSA last year, and the level of applications to obtain this green light for floaters has remained stable in 2015.

A large number of mobile units have been issued with an AoC in recent years, with Maersk Drilling’s Maersk Interceptor becoming the 56th recipient in December 2014.

Launched in the early 2000s, this acknowledgement from the PSA qualifies such facilities to work on the NCS. Maersk Drilling was the fifth and final applicant in 2014.

Supervision coordinator Odd Rune Skilbrei, who has long experience of following up mobile units, reports that several AoC requests are on their way for 2015.

“Their number will be more or less the same as in the year before. We have a good overview of newbuildings ordered for the NCS, and no reports of cancellations.”

Virtually all applications for AoCs in recent years have related to newbuildings, which accordingly come to the NCS directly from the yard. Only one of the newcomers in 2014 had served elsewhere when the AoC application was considered.

Despite the many new rigs entering the NCS, the overall number engaged there has remained stable. That primarily reflects a slowdown of the rig market, with units laid up or sent to other continental shelves.

AoC in brief
An acknowledgement of compliance (AoC) from the PSA expresses confidence that petroleum operations can be conducted by the relevant unit within the parameters set by the regulations.

Objects of this scheme include clarifying the division of responsibility between operator and contractor/unit owner.
