Prelude Floating LNG Terminal


Probably the most exciting project in the world of Oil & Gas. The platform will be the largest ship ever built

High Pressure High Temperature Systems / Pipe-in-Pipe

  1. Montrose Arbroath Oil And Gas Field
    • Shaw and Cayley
    • KW1592
    • Talisman
    • 2012
    • UHB Assessment of HPHT Pipelines ranging from 10km to 17km which included insulated pipes with a design pressure at 296 bar and design inlet temperature of 110°C and outlet temperature of 90°C; a piggyback pipeline with a design pressure at 524 bar and design inlet temperature of 112°C.
  2. Orlando Oil Field
    • United Kingdom - North Sea
    • KW1459
    • MPX / Vision Oil
    • 2011
    • Concept and FEED for subsea tie back development comprising of a 6" or 8" production line from the Orlando field in the Northern North Sea to the Ninian Central Platform.
    • A 10km line will be insulated and operate at 375 bar and 110°C. Different material and configuration options were considered, including PIP.
  3. Broom Oil Field
    • United Kingdom - North Sea
    • KW1316
    • Technip
    • 2010
    • Assessment of reeling of the 12/16" PIP and effect of reeling on operation and UHB. Pressure was 207 barg and temperature 80°C.
  4. Shah Gas Development
    • U.A.E.
    • KW1110
    • GASCO / Fluor
    • 2008
    • FEED design of an onshore Sulphur Transportation System, in the UAE. The system consists of a series of insulated PIP pipelines (adding up to a total of over 800km), in which molten sulphur is transported on the inner pipe. In the annulus of the PIP system, superheated water is circulated to maintain the sulphur temperature within the range at which it can be transported in liquid format, i.e. between 125° and 150°C. The design also includes single, insulated water return pipelines to circulate the superheated water.
  5. Jasmine Gas And Condensate Field
    • North Sea
    • KW1028
    • ConocoPhillips
    • 2008
    • The Jasmine Field (nominally HPHT) is a rich gas condensate field located approximately 9km west of the existing Judy platform in ConocoPhillips J-Block operating unit.
    • Key is experience of scour and fishing in the area and previous work on Jade pipeline project. KW provided CoP with some of the Pipeline Concept Engineering Services by considering different pipeline options (i.e. single insulated pipeline and pipe-in-pipe options) and insulation coatings.
    • Different pipeline configuration options were considered such as cooling spools with pipeline trenching and backfilling, shallow burial with intermediate spools and surface snake lay option.
    • The vulnerability of different pipeline options to upheaval buckling and lateral buckling were all assessed.
