Cameron Highway Offshore Pipeline System

The Cameron Highway Offshore Pipeline System (CHOPS), co-owned by Enterprise Product Partners L.P (Enterprise), is a deep water crude oil transport system with a capacity of 600,000 barrels per day (BPD). It stands as the longest offshore oil pipeline in the US, measuring in excess of 390 miles. It is the first to bring multiple production streams from the Louisiana Gulf to the main hubs of Texas City and Port Arthur.

DII was contracted by Enterprise to fabricate and hook-up the Ship Shoal 332 B platform and the High Island A5C platform for the CHOPS project. Three topside components of 3,500 tons, 2,500 tons and 1,500 tons were fabricated and loaded out. To meet the aggressive schedule, DII worked almost 600,000 man hours, a 24/7 effort without incident and accident free.

A key element in DII’s success was the use of our heavy-lift tower system which allowed for fabrication and outfitting of large sections at ground level. The use of our shops in our New Iberia and Lake Charles yards for major structural and piping pre-fabrication allowed DII to minimize weather delays.
