In April 2003, Sohmen family interests acquired a majority of the shares of Bergesen and, subsequently, launched a public offer through World Nordic APS for the remaining shares. Bergesen’s shares were delisted from the Oslo Stock Exchange and the London Stock Exchange in July 2003. Bergensen together with the Sohmen family’s World-Wide Shipping were reorganized to form Bergesen Worldwide in 2004, and in 2005 it was listed on the Oslo Stock Exchange under the name Bergesen Worldwide Gas ASA.
In 2007, Bergesen Worldwide Gas ASA was renamed BW Gas ASA as part of a re-branding exercise of the BW Group. Together, the BW Group of companies is a leading global maritime group involved in oil and gas transportation, floating gas infrastructure, environmental technologies and deepwater production. BW Group has a combined fleet of over 300 vessels which includes Very Large Crude Carriers (VLCCs), refined oil tankers, chemical tankers, LNG and LPG carriers, and floating production storage and offloading (FPSO) units.
