The major cost components of subsea CAPEX are equipment, testing, installation, and commissioning. The key cost drivers for subsea CAPEX are number of wells, water depth, pressure rating, temperature rating, materials requirement, and availability of an installation vessel. Subsea cost refers to the cost of the whole project, which generally includes the capital expenditures (CAPEX) and operation expenditures (OPEX) of the subsea field development.
