CNOOC DF13-2 Fixed Platform

Project overview

The Dongfang 13-2 gas field is located in the Yinggehai Basin in the western South China Sea, at a water depth of about 70 m, with proven reserves of about 100 billion m³. The development deploys one central platform and two wellhead platforms with 30 production wells, producing over 3 billion m³ of natural gas per year after commissioning. The project is included in JOTUN's marine engineering solutions brochure.

Anti-corrosion (fire protection) challenge

• Construction in 70 m open sea; the jacket anticorrosive coating shall be applied once and for all at the onshore prefabrication stage;
• High temperature, high humidity and high salt spray combined with the hydrocarbon media environment of the gas field;
• The process area of the central platform has fire zoning requirements.
