High Pressure, High Temperature
Scroll down for more
HPHT developments are typically defined as having a reservoir pressure > 690 bara and temperature >150oC. We have developed designs and development concepts for pressures and temperatures well above this (over 1,000 bara and 180°C).
We offer a systems approach looking at facilities, pipelines, overpressure protection and operational and production issues, for example:
Topsides process design implications and HP/LP management
Development of overpressure protection philosophies
Flare capacity studies
Advanced Finite Element Analysis (FEA) of the HPHT pipeline system over a hazardous seabed
Materials selection for subsea and surface components
Thermo mechanical design of flowlines, jumpers, PLETs and wellbay
Choke valve specification and failure analysis including dynamic simulation to quantify transient flow.
We have the experience to undertake and manage SIL assessments and have progressed both subsea and topsides HIPPS systems through to testing and commissioning.
We keep up to date with equipment and material capabilities, and regulatory requirements, to ensure we successfully address our clients’ future needs.
