2.3.2 Marine Repair and Maintenance 



The petroleum industry uses many types of vessels in offshore 

 activities. These vessels may be owned by the oil companies, by support- 

 ing companies, or by independent companies whose business is making 

 necessary support vessels available on a charge basis (see Figure 30). 

 A partial list of these vessels is given in Table 12. Examples of 

 typical support vessels built by a major supplier are profiled in Figure 

 31.

Shipyards, or marine repair and maintenance facilities, are used to 

 keep these vessels in good operating condition. The industry is not a 

 single firm or specific facility, but rather a range of firms that are 

 used to repair and maintain the wide variety of OCS-related vessels and 

 equipment. These firms already exist in many ports to maintain all 

 types of commercial marine vessels, and the development of OCS-related 

 activities will be an additional source of work and income to these 

 firms. Although OCS activity may stimulate additional firms, there is 

 a greater likelihood for existing firms to expand.
