Subsea HIPPS and Pipeline Design
Ian Matheson, Principal Consultant, Atkins Boreas
As reservoir pressures increase, the use of Subsea HIPPS is becoming more common. A subsea HIPPS is a complex system, but deployment of a HIPPS can lead to many benefits for the pipeline designer. The overall cost savings associated with the HIPPS can be much more than the simple saving in the cost of steel. This presentation outlines the pipeline design challenges presented by a high pressure development and outlines how the use of a subsea HIPPS can deliver a more elegant and cost effective design.
Subsea Valves for HIPPS Final Elements
Chris Williamson, Director of Product Development, BEL Valves
Valves used as final elements in subsea HIPPS must be selected, designed and qualified to ensure that high reliability and high integrity is not comprised over the entire design life of a subsea HIPPS system, which may be up to, or even exceed, 30 years. This presentation discusses aspects of valve selection, functional safety, design requirements and qualification testing to ensure valve closure on demand, in the required time and to specified (zero) leakage requirements. The requirements of the recently-introduced API RP 17O 'Recommended Practice for Subsea High Integrity Pressure Protection System (HIPPS)' are highlighted throughout the presentation.
