Sakhalin 1 Major Turnaround 2016

Return to the previous page. Go back

In August 2016, Exxon Neftegas Limited (ENL) successfully conducted a major turnaround across all five of their Sakhalin-1 facilities. As ENL’s Electrical, Instrument and HVAC maintenance and modifications contractor, Kentech played a central role in ensuring the Turnaround’s success

Maintenance

We delivered the 10 Year Preventative Maintenance for all Medium Voltage (MV) and Low Voltage (LV) switchgear across the entire Chayvo facility. Due to the scale of the task, a team of 70 additional expatriate technicians were mobilized to execute the inspection, maintenance and testing of switchgear in over 30 switch room locations. This expatriate team had just completed a similar major turnaround for Kentech in Shell’s Qatar operations, and so were the obvious choice to support the ENL 2016 turnaround – the largest since Sakhalin-1 first started production 10 years previously.

The expatriate team were joined by Kentech’s local Russian electrical specialists to oversee the scope of works and ensure compliance to all Russian regulations and local standards.

Key Project Successes:-

  • Careful months of front-end planning
  • Critical path analysis for all technical aspects of scope
  • Detailed sequencing scenarios of electrical isolations
  • Arranging visas and cross-globe mobilization coordination of the expatriate team
  • Successful management of all aspects of health, environment, security and safety across dual language operations for 24 hour shifts of work

Modifications

Our modifications team were tasked with planning, engineering, procurement and safe execution of a number of high profile, and high risk projects. These included:-

  • the retrofit of two separate flare systems – one onshore flare upgrade of electrical and instrument monitoring and ignition systems; and another upgrade of the Berkut offshore platform’s flare heat-tracing system to eliminate ice-build up issues during the cold winter period.
  • delivering, ahead-of-schedule, the engineering, fabrication and installation of a fit-for-purpose Arc-Flash ducting system in ENL’s onshore substations, ensuring safe redirection of potential arc-flashes from switchgear to exhaust, thereby safeguarding electrical personnel working in electrical panels across the facility for the remainder of the asset lifetime.

The critical outcome of these high risk activities stretched the team to capacity, and relied on guys giving up some, or most of their leave to achieve completion. We don’t see the extra mile as extra, it’s just what we do.
