IPU

Integrated pipeline umbilical. Source: API RP 17A, Design and Operation of Subsea Production Systems—General Requirements and Recommendations, Fourth Edition, Reaffirmed 2011. Global Standards  

IPU

An IPU is typically an assembly of small-bore components such as service lines, chemical injection lines, hydraulic lines, electrical and/or fibre optic cables, etc. arranged around a larger central production, injection or service line. If flexible pipe is used for the central line, it is common to use thermoplastic hoses for the small-bore fluid lines, however metal tubes can also be used in this configuration. If such an IPU type arrangement is also used on the seabed, then typically the tail end of the IPU is simply pulled up and suspended from the FPS in order to avoid additional connections in the lines.

HAZOP

HAZOP is a rigorous and widely accepted technique for hazard identification. A system or process is studied by a team who systematically look for the cause and effect of deviations from the norm. The team will, in general, be considering the following questions: • What is the design intention of the plant? • What deviations from the design could occur? • What might cause such deviations from the design intention? • What would be the consequences of such deviations from the design intention (such as fire, toxic release, etc.)? See appendix 6 for further information on HAZOP studies.
