Tanker based FPSO and FSU Experience

Global Maritime has been directly involved in tanker-based floating production, storage and shuttle systems for over twenty five years. We have undertaken feasibility studies, conceptual design works, cost estimation exercises and mooring designs. We have also advised on tanker operations, tanker conversion and conversion to dynamic positioning. A brief summary of some of our major projects appears below:
