Built in Singapore in 2013, the Britoil D-Class series of five sister Anchor Handling Tug Supply (AHTS) vessels was designed for versatility, reliability, and offshore performance. Over the years, the vessels operated across different fleets in some of the most demanding offshore environments worldwide, undertaking a wide variety of duties including offshore wind farm support, accommodation support, and the range of AHTS services for the oil and gas sector.

At the start of 2025, Britoil successfully brought the entire series together by welcoming Britoil Dominance and Britoil Dignity to join their sisters, Britoil Dragon, Britoil Destiny, and Britoil Diamond, under the Britoil flag, completing the collection.

Each vessel delivers approximately 7,000 BHP, a 650 m² clear deck, and around 90 t bollard pull, with DP2-class capability and accommodation for 66 personnel. Purpose-built for anchor handling, towing, and offshore support, the Britoil D-Class series continues to set the standard at sea, reflecting Britoil’s commitment to delivering excellence offshore through reliable and sustainable services.

Together, they embody what it means to Be Outstanding at Sea
