technologies, including a new NKK steel for low-temperature use (below -50 °C), latest welding techniques and high-strength, light-weight concrete construction technology to resist ice pressures. Mr. Yamamoto said the new mobile drilling island will be re- floatable to move to new locations, and when compared with gravel islands, features low construction cost, low operational cost and safer operation. Tenneco In Joint Venture To Operate Its Own Service Boats In Gulf Tenneco Inc., Houston, Texas, recently announced that two of its subsidiaries and a Norwegian company are forming a joint ven- ture, Argosy Offshore Ltd., to own and operate oil field service boats in the Gulf of Mexico. Tenneco Oil Exploration and Production and Philadelphia Life Insurance Company, both Tenneco Inc. subsidiaries, and Wilhelm Wilhemsen of Oslo, Norway, have agreed to a plan under which about 20 vessels will be used to support Tenneco Oil's extensive exploration and production activi- ties in the Gulf, Tenneco said. About half the vessels, Tenneco said, are relatively new and have been in limited service in the Gulf. The others are either under con- struction in the United States or are covered under construction options. Argosy Offshore will be head- quartered in Lafayette, La. Oper- ations will be headed by general manager Fred Lentjes, formerly with Tenneco Oil. Boats will oper- ate out of Intracoastal City, La., and Sabine Pass, Texas. Crews will be U.S. citizens, Tenneco said. Tenneco said it anticipates the operation will meet the require- ments of about 35 per cent of its current service boat needs. The re- mainder of its boat services will continue to be contracted from other operators. "Tenneco Oil's decision to own and operate its own boats follows studies that indicate it is econom- ically feasible to do so," explained Phil Oxley, president of Tenneco Oil Exploration and Production. The operation, Tenneco said, could provide about 150 jobs within the first year if all construction op- tions are exercised. Startup is an- ticipated during the last quarter of this year.
