The contractor said this was the longest subsea HDPE segment pulled through apipeline in one single pull for client OXY Qatar. The pipe length was 2.5 km (1.56 mi) with a diameter of 590 mm and 15 mm wall thickness. Water depth was up to 20 m (66 ft).
The operation allowed the operator to save the cost of an expensive exotic material (Inconel) overlay/lining of the pipeline, used for produced water disposal. Work was completed in August.
