ABSTRACT

Dubai Petroleum Company operates two SBM crude oil loading systems in the Arabian Gulf. The entire facility, including storage, is located 58 miles offshore and is completely self-contained. SBM 1, capable of offloading rates of 35,000 barrels per hour, has been in operation since 1969. SBM 2, with an offloading capacity of 100,000 barrels per hour, has been in operation since February, 1973. At the time of installation SBM 2 had probably the highest loading rate capacity of any SBM installation in the world. Operating experience to date indicates that loading rates of 93,000 barrels per hour can safely be obtained and that berth occupancy and tanker turnaround times can be significantly reduced.

INTRODUCTION

Dubai Petroleum Company is a wholly-owned subsidiary of Continental Oil Company and is the operator of a concession located offshore Dubai, a member country of the United Arab Emirates in the southern end of the Arabian Gulf(Fig. 1). International firms participating in the concession with Continental Oil Company are Compagnie Francaise des Petroles, Hispanoil of Spain, Deutsche Texaco A.G., Dubai Sun Oil Company and Delfzee Dubai Petroleum N.V.

Oil was first discovered in 1966 at a location fifty-eight miles offshore and designated as Fateh Field (Fig. 2). Facilities were installed and the field commenced production in 1969. Facilities initially consisted of a well platform containing six wells, a central production platform, three storage vessels, and a SBM system (Fig. 3). Three additional well platforms were subsequently drilled and increased the production system rate to a maximum of 140,000 barrels oil per day. The storage vessels have a total capacity of 1.1 million barrels and include Majmaa 1(280,000 bbls), Majmaa 2(340,000 bbls) and Khazzan 1(490,000 bbls). The Majmaas are tanker fore-bodies which have been modified to floating storage vessels and Khazzan 1 is an underwater storage tank which rests on the sea floor in 140 feet of water. The 35,000 barrel per hour loading system has accommodated 250,000 DWT tankers. Operational aspects of this facility have previously been reviewed in other technical papers (Ref. 1, 3).

In 1970 a discovery well was drilled 10 miles to the south west. Due to the close proximity of the new South West Fateh Field and because of expanded development within the Fateh Field, it was necessary to install additional production, storage and off loading facilities. This expansion phase was completed early in 1973 and provided for an additional 300,000 barrel per day separation capacity, two additional submerged storage tanks (1.0 million barrels) and an additional SBM rated at 100,000 barrels per hour.
