COSL Drilling Europe AS

Always do better is our guiding principle leading us through the energy transition and towards our vision of becoming the preferred supplier of drilling services. We are known for having the most efficient drilling units and a strong safety performance and culture.

COSL Drilling Europe was established in 2005, and has its head office located in Stavanger, Norway. Today we operate four modern drilling units. We have a solid owner with stable ratings in China Oilfield Services Limited, listed at the Shanghai Stock Exchange, with ambitions to strengthen its foothold in the North Sea.

Our four semi-submersible drilling rigs were delivered from the yard respectively in November 2010 (COSLPioneer), November 2011 (COSLInnovator), May 2012 (COSLPromoter) and November 2014 (COSLProspector). The first drilling operations started in Norway in August 2011 and COSL Drilling Europe has since then been in continuous operation drilling and completing wells in Norway, UK, Faroe Islands and New Zealand.

The drilling units are of a similar design and have all proven strong and consistent performance deliveries.

Our rig portfolio has a proven track record of having the most efficient and best-performing rigs in the North Sea. COSL is setting a new standard in the North Sea with its energy efficiency. Our ambition is to deliver carbon neutral drilling operations within 2025.
