Perculator a unified cost estimating and economic evaluation tool, gains early insights of economic assessments in a portfolio of development options.  This tool was developed using the experience of front end estimation across a broad range of clients and developments through a collective effort spearheaded by our Field Development team supported by the Subsea Systems,Read more

Offshore pipeline installation is costly wherever it is performed but especially so in regions with high labour costs and/or distant from the major offshore working hubs. Conventional installation methods (S Lay) typically require crew sizes of 250-350 personnel offshore for extended periods of time plus considerable support . This article explores alternative installation methods someRead more

Computational Fluid Dynamics (CFD) has gained momentum since the late 20th century. Its strength as a high-fidelity predictive software combined with powerful graphics allow visualisation of multi-dimensional problems. The visualisations are often helpful in pin-pointing an issue relating to physical flow behaviour of fluid particles and their interactions with the surroundings. As such, many peopleRead more

Traditionally subsea flowlines are rated to the full shut-in tubing pressure (SITP) of the well. Most of the time, the operating pressure is far below the SITP. If the flowlines can be designed for operating pressure rather than for SITP, field development costs can be significantly reduced, especially where long tie-backs are involved in combinationRead more

Peritus has performed global dynamic analysis of two flexible risers as part of detailed design for tie-back to a spar platform. The spar platform is located in the Mississippi Canyon region of the Gulf of Mexico in a water depth of 2200ft.  Peritus’ scope for the riser analysis included: Design Premise and Analysis Summary ReportRead more

To qualify Indian pipe mills to supply linepipe for the Deepwater Pipelines pipe ring samples were collapse strength tested. Consideration was given to water depths up to 3500m and consequently subject to very high external pressures which make the pipe collapse strength a major consideration for any project. The linepipe manufacturing process involves a coldRead more

Peritus has now completed a project on pigging a subsea tie-in of a new 14” oil export pipeline into an existing 30” trunkline.  The project was part on a new field development that requires access to an existing trunkline for export to an onshore terminal.  The project was undertaken alongside a more conventional approach whereRead more
