Yemen's multi-billion dollar oil export projects represent two of the largest projects ever undertaken by the Company: Canadian Occidental Petroleum's 1991-1994 Masila Export Project and the 1984-1987 Export Facilities Project for Hunt Oil and Exxon. Gulf provided full EPCM services for both of these projects.

Similar in scope and size, both projects were grassroots oilfield developments encompassing every component from the wellhead to the export terminal: oil gathering pipelines, a central production unit to process the oil, an export pipeline system, pumping and pressure reducing stations and a marine export terminal. The Export Facilities project used a marine loading line to fill a captive floating storage offshore (FSO) tanker to store and transfer the crude oil for export. The Masila Export Project featured onshore storage tanks and a marine loading line coupled to a mooring buoy for export tanker loading. The production capacity of each system is 120,000 barrels of oil per day. The pipeline system for the earlier project was the longer of the two at 425 kilometers, while the later project's pipeline was 140 kilometers. Both projects included large field power plants to generate the energy requirements for the central production units. The conversion of an existing oil tanker into the FSO tanker for the Export Facilities Project was a project-within-a-project.

Gulf's services began with conceptual and preliminary engineering studies for both projects to develop cost estimates and define the export systems for detailed engineering and the procurement of long-lead equipment and materials. The Export Facilities Project followed a conventional 36 month project implementation schedule, but the Masila Export Project was executed on a fast-track basis, with first oil for export achieved within 18 months of the start of detailed engineering. Gulf's project management, engineering, procurement and construction management services called for the development of large project teams and the deployment of personnel worldwide to coordinate equipment manufacturing, perform vendor shop inspections and to manage and inspect the construction in Yemen. Hundreds of engineers, technicians and other specialists, working from Houston, in project offices worldwide and on the ground in Yemen, were required to meet the logistical requirements of these complex projects and their dynamic execution demands. And all of this without the aid of e-mail or cellular telephone communications.
