The Stena Carron is a monohull drillship that’s dynamically positioned and was delivered from South Korea’s Samsung Heavy Industries Shipyard in August 2008. It was the second of three drillships in the DrillMAX series, with the first in 2007 being the series’ namesake. One year later, the Forth completed the trio.
United Kingdom-flagged, the Stena Carron was built to accommodate 180 crew members and can drill in water depths reaching a maximum of 10,000 feet. It has a length of 748 feet, a breadth of 138 feet, a gross tonnage of 58,294 tons and a deadweight tonnage of 97,000 tons.
Originally beginning drilling operations for Chevron in the Shetland area of Scotland, the Stena Carron then moved on to Newfoundland to work in the Laurentian Basin. Beginning in May 2010, the drillship worked in a remote area approximately 155 miles from the Hibernia oil field. Over the course of 106 days, it completed its work, though it did sustain some minor damage above its water line.
Controversy then developed when Greenpeace activists blocked the Stena Carron’s path in the North Sea on the way to the Lagavulin oil field. That turned out to be a brief stoppage in the ship’s ability to produce and by 2012, it was working for Valiant Petroleum to drill the Handcross Prospect.
Once that work was completed, the Stena Carron was headed to Africa to work off the coast of Angola for Statoil on a three-year, $700 million contract. However, toward the end of 2014, the economic toll of limited positive results and dropping oil prices forced an abrupt cancellation of the contract.
Success returned when Exxon contracted the Stena Carron to work off the coast of Guyana on its Liza-2 well. There, a significant discover was achieved in June 2016.
