Method for evacuating hydrocarbon from a subsea process module

A method for evacuating hydrocarbons from a number of pockets within a subsea process module, the subsea process module having a number of upper fluid connection points and a number of lower fluid connection points, the method comprising:

• connecting a receiving container line to one of said upper fluid connection points of the subsea process module;
• connecting a liquid adding line to one of said lower fluid connection points of the subsea process module;
• displacing hydrocarbon from the subsea process module through the receiving container line by adding a liquid displacement medium through the liquid adding line;
• removing the liquid adding line from said one of said lower fluid connection points;
• connecting a gas adding line to one of said upper fluid connection points or one of said lower fluid connection points;
• connecting the receiving container line to one of said lower fluid connection points;
• and
• adding a gas medium through the gas adding line to thereby dilute a gas-phase portion of the hydrocarbon that has been trapped in at least one of said pockets within the subsea process module.
