Parallel Big Bowl CD 600 Slim Line Hydraulic Centrifuges Installed onboard Ensco 107 at KFEL

Shipyard Singapore for Premier Oil Vietnam

CHALLENGES

Limited deck space on shaker module roof.

Share of shaker module roof with MWD / Logging Containers

Big bowl Centrifuges had to fit the same footprint deck space for duel standard 518 centrifuges

Due to combined weight of the centrifuges / MWD & Logging containers the Shaker module had to have additional strengthening carried out

Centrifuge support frame required Ensco Engineering and ABS approval, structural analysis to withstand towing conditions

Due to wide load road limitations in Singapore the Centrifuge support frame was designed as pre fabricated modular flanged sections which also reduced hot work requirements during install with consideration for a cold work de mobilization on

completion of contract

A total of 8 sacrificial welded anchor pads were fitted and to compensate for deck deviations the tie brackets were designed to adjust height prior to welding down the

sacrificial Anchor pad, The solids hoppers were pre fabricated and were flanged for ease of install and de mob multiple spray bars and Teflon sheets fitted internal to ensure the large

volume of solids discharged from the big bowl centrifuges are flushed freely overboard

Positioning and securing the Centrifuge Bowl frames to base frame

Positioning and securing the 2 pre fabricated support frames for the Centrifuge Hydraulic Power packs which will be located on the upper level of the frame

Installation of the pre fabricated walk ways / hand rails and access ladder to the Hydraulic power pack platform,

Centrifuge Hydraulic Power Packs positioned and secured on the upper level of support frame, the only hot work required to get to this stage was the 8 sacrificial anchor pads, matching

flanges for the 2 solids hoppers and deck flanges for the 2 feed tube lines everything else is flanged and bolted
