• List of GLF Customers

Our principal customers are major integrated oil and natural gas companies, large independent oil and natural gas exploration and production companies working in international markets, and foreign government-owned or controlled oil and natural gas companies. Additionally, our customers also include companies that provide logistic, construction and other services to such oil and natural gas companies and foreign government organizations. Generally, our contracts are industry standard time charters for periods ranging from a few days or months up to ten years. Contract terms vary and often are similar within geographic regions with certain contracts containing cancellation provisions (in some cases permitting cancellation for any reason including, without limitation, convenience) and others containing non-cancellable provisions except in the case of unsatisfactory performance by the vessel. We had revenue from BG Group and Anadarko Petroleum Corporation in our North Sea and Americas regions.

Contract or charter durations vary from single-day to multi-year in length, based upon many different factors that vary by market. Additionally, there are “evergreen” charters (also known as “life of field” or “forever” charters), and at the other end of the spectrum, there are “spot” charters and “short duration” charters, which can vary from a single voyage to charters of less than six months. Longer duration charters are more common where equipment is not as readily available or specific equipment is required. In the North Sea region, multi-year charters are more common and historically have constituted a significant portion of that market. Term charters in the Southeast Asia region have historically been less common than in the North Sea and generally have terms of less than two years. In addition, charters for vessels in support of floating production are typically life of field or “full production horizon” charters. In the Americas, particularly in the U.S. Gulf of Mexico, charters vary in length from short-term to multi-year periods, many with thirty day cancellation clauses. In Brazil, Mexico and Trinidad contracts are generally multi-year term contracts. As a result of options and frequent renewals, the stated duration of charters may have little correlation with the length of time the vessel is actually contracted to provide services to a particular customer.
