Two recent conversions of semisubmersibledrilling units to floating productionfacilitieswere governed by a differentset of design requirements and operator philosophies. This paper compares them and illustrates how fabrication philosophies were chosen to produce a cost-effective project for each. OTC 7S33 HARVEV E. McBEE, RICHARDS. Hll& PEIER G.S. DOVE 7

This paper presents the key elements involved in the selection of the Ocean Victory Class semisubmersible drilling vessel by Enserch Exploration, Inc. for conversion to a Floating Production Facility (FPFJ. (t also presents an overview of the various facets of engineering required to specify and procure all mooring, production facilities and marine systems equipment, and all structural and naval architectural design work necessary to obtain ABS classification and provide a conversion specification bidpackage and detailed design.
