Effluent Treatment Plant, Pearl GTL

Return to the previous page. Go back

The Pearl Shell GTL (Gas to Liquids) Project is an integrated development of upstream gas production facilities as well as an onshore GTL plant which will produce 140,000 barrels per day of GTL products and base oils.

For this commission, Kentech had responsibility for the water treatment plant which forms an integral part of the gas to liquids process.  The onshore portion consists of a two train GRL plant divided into 8 project areas named C1 to C8.  Kentech’s commission was in the C8 section.

Our scope was to perform the necessary electrical, instrumentation, HVAC and firewater ring main construction and testing works.

The electrical works involved the procurement of electrical bulk materials including all cable ladders and glands. The installation and testing of two 20 MVA, three 12.5 MVA and eight 6.6 KVA transformers with associated switchgear, installation of cable trays and ladders as well as associated cabling. A total of 1,500 kilometres of cables were installed, 1,500 kilometres of which were underground.  The instrumentation scope involved the procurement of instruments and instrument bulk materials, calibration of instruments, plus pre-commissioning of the control system and loop checking prior to commissioning.

In relation to the HVAC works, we were responsible for the design, procurement, fabrication and installation of all duct work, dampers, grilles, diffusers, fans, plus installation of all HVAC equipment. Testing and commissioning of the HVAC system in 8 buildings including 5 dedicated process buildings was also part of our scope.

The firewater system covering the C8 plot consisted of over 2 kilometres of GRE piping, ranging in size from 4 inches to 14 inches and we were also responsible for the installation of fire hydrants and the testing of this system.  This was especially challenging, given the outdoor nature of the work and the temperature extremities.  A specialist team of certified and trained fitters completed the works, involving lamination, barcol testing, bell and spigot joint integrity and hydrotests up to 24 bar pressure.


On Tuesday 9th February 2021, we announced an agreement to acquire the oil & gas business of SNC-Lavalin’s Resources Division.

This business includes people and assets brought together through their acquisition of the Kentz and other energy services businesses. This transaction marks an exciting, ground-breaking development for Kentech to reinforce our position as a leading integrated energy services provider and introduces us to the renewable / clean power marketplace. We now move forward together with a global network of more than 10,000 professionals united by a commitment of common values and strong partnerships with clients from across the world.

By investing now, we are strategically positioning the company to take advantage of the next cycle of growth.

Our complementary businesses will join forces, creating a stronger offering across the full asset life cycle – from consulting to design and build, commissioning and start-up, through to maintenance, modification and turnaround, as well as decommissioning services.
