CNOOC Wenchang Oilfield Group Fixed Platform

Project overview

The Wenchang oilfield group is located in the western South China Sea. The group has built several wellhead platforms including Wenchang 13-1/13-2, 19-1D and 16-2, with jackets over 128–160 m high, of 8-leg light jacket and multi-skirt-pile construction. The project is included in JOTUN's Anticorrosive Coating Solutions for Marine Engineering Structures.

Anti-corrosion (fire protection) challenge

• The South China Sea is hot, humid and salt-laden with strong UV, demanding high topcoat weathering;
• The splash zone is subject to long-term wave impact, being the focus and difficulty of platform corrosion protection;
• The mudline section and splash zone of the jacket require zone-by-zone coating system design.
