The Cameron subsea pressure intensifier (SPI) enables increasing the usable control fluid stored in subsea mounted accumulators by boosting the working pressure from a conventional 5,000 psi [34.5 MPa] up to the full rated pressure of 7,500 psi [51.7 MPa].
Available for new-build rigs or as a retrofittable option, the SPI is a space-saving, economical solution that enables you to
- improve shearing capability
- extend your operating work area into greater water depths
- use nitrogen gas instead of costly helium gas (stack dependent)
- minimize the weight increase on existing BOP stacks
- increase your capacity to comply with Bureau of Safety and Environmental Enforcement (BSEE) Well Control Rule and API Spec 16D.
