A circular letter is an identically-worded communication sent to all or selected groups of players in the petroleum sector, depending on whom the content is relevant for.
There have been several incidents in recent years of break-through of cuttings and fluid to the seabed from wells that for injection of cuttings and other operational fractions.
In several cases, we have become aware of incidents as a consequence of annual inspections of the facilities on the seabed, or as a consequence of discharges observed on the sea surface.
The incidents have entailed pitting on the seabed, with deposits of cuttings and flow of liquid, or, in some cases, ridges on the seabed.
