Sakhalin – 1 Overview

Return to the previous page. Go back

The Sakhalin-1 Project is an oil and gas development on the northeast shelf of Sakhalin Island. The project area includes the Chayvo, Odoptu and Arkutun-Dagi fields. Total recoverable reserves are estimated to be 2.3 billion barrels of oil and 17.1 trillion cubic feet of natural gas.

In line with Kentech’s philosophy to support clients from the earliest stage of asset development, Kentech commenced work on Chayvo in 2003, providing engineering, procurement and construction of mechanical and electrical services to upgrade and expand the existing camp facilities in Chayvo.

In late 2004, Kentech mobilized to complete the Early Production Facility (EPF). The EPF allowed production from the field while the main OPF was under construction. Kentech was responsible for completing the mechanical, electrical and instrumentation installation of more than 55 skids, some of which were up to 60 metric tonnes for this 50,000 b/d facility.

In late 2005, Kentech signed a contract with Bouyguestroi to provide mechanical and electrical services for the construction of the ENL head office in Yuzhno.

Kentech decommissioned and mothballed the EPF in advance of its move to the Odoptu field, for the next phase of Sakhalin 1 in early 2007. The construction of the camp for the Odoptu project was also awarded to Kentech by Fluor early in 2008. The 300 man, 170 module camp was fabricated in Yuzhno and shipped to Odoptu in August and September of 2008.

In 2008 Kentech provided comprehensive electrical and instrumentation services on the Odoptu and Chayvo Production Facilities and later installed the cathodic protection system to the 92 kilometre pipeline from Odoptu to Chayvo OPF. Kentech also partnered with ECC VECO on Odoptu to provide electrical and instrumentation services for the process facility and modifications to the Chayvo Process Facility.

In 2010, Kentech were awarded a project by STSN to provide electrical and instrumentation services on the expansion of the existing distribution board and cable replacement works on the Chayvo OPF.

In 2011, Kentech completed their first commission on the Arkutan Dagi site. We installed the cathodic protection system to 92 kilometre pipeline from the North Odoptu Well Site to the Onshore Process Facility at Chayvo. 201 anodes, 92 test stations and 6.5kms of cable were installed along the length of the pipeline. We also carried out a maintenance and repair project for ENL on the 125km pipeline from Chayvo OPF to Cape Uangi on the West coast of Sakhalin.

In 2012, Kentech carried out a design and build project on behald of Fluor to provide temporary accommodation modules for the Orlan Offshore Platform. The modules were constructed in Yuzhno and transported to the Orlan for installation and commissioning. We also began the E&I contract on the Orlan Platform Well Bay Area Retrofit project for the same client. On behalf of ECC Veco we carried out the E&I installation, test and commissioning activities associated with a 2 well expansion project on Odoptu North Well Site.

In 2013, Kentech were awarded the structural, electrical, instrumentation, fiber optic cable and piping scope of work associated with the electrical and instrumentation installation for the 2013 scope of the CWSE project. Kentech were also awarded 3 contracts on the Berkut Platform. For DSME, we completed offshore hookup and commissioning activities and for Exxon we provided commissioning support works for the offshore modules moving from Korea and then to offshore Sakhalin and also specialist E&I technicians for hands on commissioning works on the onshore element.

In 2015 we were awarded the electrical, instrumentation and telecommunications construction and commissioning scope of work on the Odoptu Stage 2 project. We delivered electrical, heat tracing and instrument tubing installations for the drilling infrastructure that comprised of office facilities, warehouse, logistics building and 2 pipe racks both on the North and South Well Sites. Once the modules were set in their final location, we proceeded to complete the cable tray, cable, instrument tubing, instrument, heat trace, grounding and light installations.

Over the past 12 years and continuing today, Kentech support Exxon Neftegas Limited on a long-term service agreement for maintenance and construction services at the Chayvo Onshore Processing Facility (OPF), the offshore Orlan Platform, the DeKastri Export Terminal and single point mooring system as well as valve station locations along the crude and gas product pipelines.

From my first arrival on the Sakhalin-1 project in 2003, the team have just grown from strength to strength.
