Sonsub Awarded Contracts From McDermott, Texaco

• Sonsub was awarded a contract by McDermott Incorporated to assist in the installation of a platform for Oryx Energy in High Island 385A in the Gulf of Mexico.

Sonsub will mobilize a 75-hp Triton Advanced Remotely Operated Work System (AROWS) and a Viper Remotely Operated Vehicle (ROV) to perform the work, scheduled to take place in October.

• Sonsub North Sea has been awarded a contract by Northern Ocean Services, a McDermott company, to provide trenching, ROV and survey services to support the Conoco Heidrun project.

Under this contract, Sonsub will provide a vessel, the Veslik Viking, a Flexjet II Cable and Pipeline Burial System, a ROV and positioning services.

The work includes the trenching of three 15.5-in. nominal outside diameter flexible flowlines and three four-in. diameter umbilicals.

A total distance of approximately 12.5 miles will be trenched. Work began in June.

Sonsub was awarded this contract following the successful completion of trenching operations on the Saga Tordis infield line which Sonsub North Sea performed under contract to Rockwater.

• Sonsub has been awarded an annual platform inspection contract by Texaco to inspect four platforms in the Gulf of Mexico.

Sonsub will mobilize a 20-hp Viper ROV to perform general visual fly-by inspections and Cathodic Protection (CP) surveys.

Video survey data will be recorded and analyzed using Sonsub's new video frame-grabbing software. The work began in July.

Sonsub recently completed similar platform inspection contracts for Marathon and Shell Offshore.
