The field includes; the wellhead protector platform (WPPA) and bridge linked platform (BLPA) which are both connected back to a floating production, storage and offloading vessel (FPSO) as well as two subsea manifolds tied back and connected to the platforms by a suite of pipelines.

Katoni’s Role in Supporting Chevron

Our close relationship with Chevron has enabled us to provide support with various multi-discipline work scopes. This work scope CHEV104, was Instrumentation specific and formed part of the Captain ICSS upgrade project. Katoni was required to as-build all the Fire & Gas Cause & Effect Diagrams to accurately represent the installed Honeywell FSC Controller Fire & Gas logic.

Collaboration in action:

Understanding Chevron’s needs & Delivery: Katoni were asked to complete the as-building work scope within a very demanding schedule to meet the Client’s FAT deadline. To satisfy the client’s requirements the Cause & Effect diagrams were issued in asset packages with staggered issue dates. In total, between the 3 assets, FPSO, WPPA & BLPA there were 154 Fire Zone Logic Maps and 154 Cause & Effect’s delivered.

The Katoni Way: Working closely with our client we were able to feed back FAT results and as-build the cause and effects for each asset package whilst testing continued on another. This allowed the schedule to be adhered to and prevented FAT impacting on internal project deadlines.

-          154 Fire Zone Logic Maps & 154 Cause & Effect Diagrams

-          £86,390 Total budget
