ExxonMobil Berkut Platform – Hook-up & Commissioning Support

Scope

Sea Trucks Group (STG) was engaged to supply temporary accommodation for the hook-up and commissioning (HUC) phase of the ExxonMobil Berkut platform. To provide this capability STG we required to:

  • to mobilise, integrate and seafasten a temporary accommodation facility onto the back deck of their vessel; the integration included the interlocking mechanical items, access and stairways
  • install an extendable aluminium gangway
  • build and deliver a bespoke landing platform for connecting onto the side of the Berkut platform capable of being lifted and stowed by the platform crane
  • Build and deliver an access stairway from the landing to the platform topsides

To complicate the delivery, the vessel was swapped half way through the engineering phase.

The mobilisation (Batam) schedule was demanding with severe commercial penalties for delays. ABS class approvals for all vessel and new accommodation modifications were required before sail away.

Given the success of West Atlas salvage and Heerema access platform, Cube were engaged to  support STG with:

  • integratation of the new accomodation modules
  • seafastening of the new accommodation modules onto the back deck of their vessel
  • design a bespoke landing platform for connecting onto the side of the Berkut platform capable of being lifted and stowed by the platform crane to avoid storm wave loading
  • design an access stairway from the landing to the platform topsides

Outcome

Cube Offshore successfully integrated and collaborated with the STG project team to produce practical designs to facilitate rapid integration and seafastening of the new modular construction of the 17 tonne, 48 module accommodation block on the J34 during the mobilisation in Batam.  Cube Offshore supported STG with attendance in Batam to prepare for, and during mobilisation. Subsequently, Cube was instrumental in helping STG achieve vessel class approvals by liaising with ABS (China) in their native language.

Cube’s lead engineer travelled to Korea to survey the platform to ensure fitup of their design to the platform.

Once on location, the Gangway Landing and Access Tower structures were installed, secured and connected rapidly and without hitch.
