Subsea 7's new pipeline spool base to support deepwater ops in GOM



Port Isabel, on the Texas coast close to the Mexican border, is the site for Subsea 7’s new US pipeline spoolbase. The facility covers 58 acres (23.5 ha) and is 5,000 ft (1,524 m) long, including a 4,000-ft (1,219-m) stalk rack and 1,000-ft (305-m) fabrication building. It will enable the company to offer an enhanced deepwater rigid pipelay service in the North America region.

The spoolbase will be able to fabricate and store individual pipe stalks up to 20-in. (50.1-cm) diameter, 16-in. (40.6-cm) steel plus 4-in. (10.2-cm) insulation coatings, in lengths up to 4,000 ft (1.2 km), with possible future expansion of up to 5,905 ft (1.8 km). It also will be equipped to weld any steel material from traditional carbon steel to duplex and clad pipe. Furthermore, the base will be able to complete fabrication of plastic lined pipe-in-pipe lines, regular steel pipe-in-pipe, and steel catenary risers (SCRs). In full production, the base will be able to hold around 19,841 tons (18,000 metric tons) of pipe stalks.
