Wärtsilä to supply subsea heating system for offshore Africa pipeline
HELSINKI -- Wärtsilä has been contracted to supply its Direct Electric Heating (Wärtsilä DEH) system for Chevron Overseas Congo Limited's Lianzi offshore development project, off the Republic of the Congo and Angola coasts.
The 9,000-kW system will be used to heat the 43-km subsea production pipeline between the Lianzi field and the Benguela Belize Lobito Tomboco (BBLT) platform. The Lianzi field lies approximately 100 km off the coast of the Republic of the Congo, and the BBLT platform is located in Angola. The pipeline is in roughly 900 m of water. The installation of the Wärtsilä DEH is intended to improve subsea flow assurance in the pipeline.
