Interim Production Facility, Sakhalin-1

Return to the previous page. Go back

Kentech was awarded a multi-disciplinary support contract for planning and executing the preservation of the Sakhalin-1 IPF.

Kentech was responsible for the construction of the IPF, which was used for early production whilst the main OPF was being constructed.  When the OPF came online, it took over the production and the IPF operation ceased.

Kentech started with the development and approval of the decommissioning plan.  The next step was the steam cleaning of the piping system and filling it with nitrogen.  Another aspect was the cleaning of the inside of the various process vessels.  This involved a whole new range of procedures, work method statements and JSA’s with a lot of specialised equipment and training.

Following completion of the mechanical works, we commenced on the electrical and instrumentation systems.

Kentech also performed periodic preventative maintenance to maintain the integrity of the facility and equipment until the future use of the IPF was established.


On 30th July 2021, Kentech acquired the Oil and Gas Business of SNC-Lavalin. This led to the exciting relaunch of our new company, now known as Kent.
