Ande-Ande Lumut Wellhead Platform FEED

Client: Santos North West Natuna BV

Location: Indonesia

Ande-Ande Lumut is a forty eight (48) wellhead platform located in the North-West sector of Natuna Sea with a telescopic bridge linked FPSO to be located 45 meters away with all interfaces between being handled by catenary suspended flexible pipelines and cables.

Production at Ande-Ande Lumut will be via electrical submersible pumps (ESP’s) with production being directly transferred to the FPSO for processing. Facilities on the wellhead platform include electrical switchgear and switchroom for supplying power to the ESP control packages (transformers and variable speed controllers). All utilities are supplied from the FPSO.

Synergy's Scope of Work

Synergy’s produced a FEED++ (detail close to construction level) of the Ande-Ande Lumut facility including all the layouts, structural design of both topsides and jacket, and the power distribution (approximately 12 MW required by the production equipment).

The work scope also included the detail design cost estimate for the facility and the proposed scheduling for the EPCI Contractor.

Key Project Achievements

Optimization of the space requirements for 48 ESP controllers and dual production manifolds for each well slot.

Full PDMS 3D design model completed with a TEKLA 3D model for the structural detailing.
