High Pressure High Temperature (HPHT)

New High Pressure High Temperature (HPHT) reservoirs continue to push subsea equipment and pipeline technology beyond current capability. Stress Subsea is actively involved in development of new technologies in this area and is committed to facilitating their use in the Gulf of Mexico. As with all new technologies, both equipment development and interface coordination with regulatory authorities play equally key roles. Stress Subsea has acted as technical consultant and interface manager on recent HPHT technology studies. In addition, Stress Subsea is actively involved in the development of recommended practices through its membership in the API 17N committee, "Subsea Production System Reliability and Technical Risk Management".

Stress Subsea is uniquely positioned to advance new technologies related to subsea systems. The organization consists of senior personnel in both subsea equipment and pipeline disciplines. Through its affiliation with Stress Engineering, significant riser and floating system capabilities further support the overall technical muscle that Stress Subsea can bring to bear on a project. Last, but certainly not least, the industry leading analysis and test capabilities of Stress Engineering, and its Mohr Engineering Division, provide rapid feedback on design performance that is essential to timely development and installation of new technologies.

Stress Subsea scope of activities has included:

    Identification of technical gaps to existing technology
    Research into HPHT systems installed elsewhere in the world
    Analysis of critical functional performance of various design          alternatives
    Identification of risks through HAZID / HAZOP analysis
    Cost-benefit analysis on technical alternatives
    Assessment of project schedule risks
    Interface with suppliers and regulators
