Daniel Revers, Co-Founder and Managing Partner of ArcLight, stated, “The partnership with VTTI is an important milestone for Petrotank. It not only validates ArcLight’s investment strategy for Petrotank, but, more importantly, the partnership adds the world class technical and commercial capabilities and resources of a global market leader to a company that is well-positioned for continued growth. We are very pleased to have VTTI join ArcLight as an equal partner in PetroLux and look forward to an exciting future together”.
