Statoil Petroleum AS has received consent to use the COSLPromotor mobile drilling facility for drilling, completion, intervention, workover and well plugging on the Troll field.

COSLPromoter is a semi-submersible dynamically positioned drilling facility, type GM4000. The facility was built and assembled at Yantai Raffles Shipyard (YRS) in China. The drilling package was delivered by National Oilwell Varco (NOV) and built at Nymo in Grimstad.

The facility was issued with an Acknowledgement of Compliance (AoC) by the PSA in 2012.

The Petroleum Safety Authority Norway has now granted Statoil consent for well operations in accordance with Statoil's application.
