In 1986, the various companies in the Bergesen group were gathered under a holding company, Bergesen d.y. ASA. This company was listed on the Oslo Stock Exchange on 9 September 1986.

Bergesen revised its strategy in 1999 and decided to focus on two new growth areas; LNG and offshore services. Bergesen was able to utilise its competencies in its core markets to enter these two areas, which provided improved and more stable returns for the company.

This renewed focus resulted in the acquisition of 11 LNG newbuildings between 2000 and 2005, of which seven are currently under construction at Daewoo in Korea. In 2001, Bergesen entered into long-term contracts with Tractebel for the first two vessels, but the real breakthrough in LNG came in 2002, when Bergesen was awarded a contract for four LNG vessels by Nigeria LNG. An addtional four vessels were later awarded by NLNG to Bergesen LNG Ltd., a subsidiary of Bergesen Worldwide Ltd. These four vessels will be managed by Bergesen Worldwide Gas. In September 2005, a letter of intent was signed with Suez LNG for a further two vessels.

Bergesen's offshore venture started with the acquisition of Scantank Offshore in 1999. Since then, Bergesen has converted five FPSOs (floating production, storage and offloading vessel) on time and on budget. Bergesen Worldwide Offshore is now a separate company within the group, focusing on oil FPSOs and LPG FPSOs in benign waters, in addition to arctic oil FSOs.
