Maersk - Chissonga Hot Oil & Pigging Operations Strategy
GATE was involved in formulating the strategy for hot oil circulation and pigging operations for Chissonga. The hot oil circulation study involved optimization of the hot oil injection pressures and temperatures required to displace the cold dead leg in the pigging loop following an extended shutdown. The pigging study involved optimizing the pigging frequency, topsides injection pressures and pig velocities taking into account the production function for the entire life of the field.
