composition of the company’s offshore service vessel fleet includes vessels that are operated under joint  ventures  as well as vessels that are stacked or withdrawn from service. The company has one of the most global operating footprints in the offshore energy industry with operations  in most of the world's significant crude oil and natural gas exploration and production regions. The company  is also one of the most experienced international operators in the offshore energy industry with over five  decades of international experience. As of March 31  2010  the company had 394 vessels (of which 10 were operated through joint ventures   83 were stacked and seven were withdrawn from service) servicing the global energy industry. Please refer  to Note 1 to Notes to Consolidated Financial Statements included in Item 8 of this report for additional  information regarding our stacked vessels and vessels withdrawn from service.  The company also operates two shipyards  which construct  modify and repair vessels. The shipyards  perform both repair work and new construction work for outside customers  as well as the construction   repair and modification of the company’s own vessels.  The company’s revenues  net earnings and cash flows from operations are largely dependent upon the  activity level of its offshore marine vessel fleet. As is the case with other energy service companies  our  business activity is driven by the level of drilling and exploration activity by our customers. Our customer's  business activity  in turn  is dependent on crude oil and natural gas prices  which fluctuate depending on  expected future levels of supply and demand for crude oil and natural gas  and on estimates of the cost to  find  develop and produce reserves. The company's worldwide headquarters and principal executive offices are located at 601 Poydras Street   New Orleans  Louisiana 70130  and its telephone number is (504) 568-1010. The company’s United States  (U.S.) marine operations are based in Amelia  Louisiana; Oxnard  California; and Houston  Texas. The  company’s shipyards and shipyard operations are located in Houma  Louisiana. We conduct our  international operations through facilities and offices located in over 30 countries. Our principal international  offices and/or warehouse facilities  most of which are leased  are located in Rio de Janeiro and Macae   Brazil; Ciudad Del Carmen  Mexico; Port of Spain  Trinidad; Aberdeen  Scotland; Cairo  Egypt; Luanda and  Cabinda  Angola; Lagos and Onne Port  Nigeria; Douala  Cameroon; Singapore; Perth  Australia; and  Dubai  United Arab Emirates. The company’s operations generally do not require highly specialized  facilities  and suitable facilities are generally available on a lease basis as required.  The company operates in two reportable segments: International and the United States. The principal  customers for each business segment are major and independent oil and natural gas exploration  field  development and production companies; drilling contractors; and other companies that provide various  services to the offshore energy industry  including but not limited to  offshore construction companies  diving  companies and well stimulation companies. The international business segment also has customers that  are foreign government-owned or -controlled organizations and companies that explore and produce oil and  natural gas.  The company’s vessels in its international segment are geographically dispersed in the major crude oil and  natural gas exploration and development areas throughout the world. Although barriers such as mobilization  costs  the availability of suitable vessels and cabotage rules in certain countries occasionally restrict the  ability of the company to move vessels between international markets  the company’s diverse  mobile asset  base and the wide geographic distribution of its vessel assets enable the company to respond relatively  quickly to changes in market conditions. As such  significant variations between international regions tend to  be of a short-term duration  as the company routinely moves vessel between and within geographic regions. The company’s internationally based vessels operate in the shallow  intermediate and deepwater offshore  markets around the world. The deepwater offshore market continues to be a growing sector of the  international offshore crude oil and natural gas markets and is the one sector that has not experienced  significant negative effects from the recent global economic recession  largely because the deepwater oil  Business Segments Offices and Facilities  -5-
