Wärtsilä has been contracted to supply its Direct Electric Heating (Wärtsilä DEH) system for Chevron Overseas Congo Limited's Lianzi offshore development project, located off the Republic of Congo and Angolan coasts.
The 9000kW system will be used to heat the 43 km long 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 Congo, and the BBLT platform is located in Angola. The pipeline lies in some 900 metres of water. DEH is a flow assurance tool used to avoid ice-like structures called hydrate plugs and the appearance of wax in production flow lines.
