North Sea Group is a key player on the Western European downstream oil market. The company combines storage and distribution with the international trading and sale of mineral oils and biofuels. The customers, including major oil companies, the international shipping industry, trading houses and resellers, have relied on the product quality and market-oriented approach of North Sea Group for decades. By expanding into Asia and South America, the European company is further broadening its position on the increasingly global oil market, paying careful attention to issues of safety, sustainability and the environment. The Group's commercial divisions trade in all mainstream mineral oil products such as heavy fuel oil, automotive diesel, heating oil, marine diesel, kerosene and mogas. Over the past few years biofuels have become a key new product group for North Sea Group. North Sea Group was founded in January 2009 to coordinate the merger between all divisions.

One-Dyas BV engages in the exploration and production of oil and gas. The firm focuses primarily on developing and exploiting gas fields in the North Sea. The company is headquartered in Amsterdam, the Netherlands.
