Leading offshore Cargo Carrying Unit and A60 module company OEG Offshore (OEG) has delivered a Variable Speed Drive (VSD) module to Bluewater Energy Services B.V. (Bluewater), a leading specialist in tanker-based production and storage systems located in the Netherlands.

OEG Offshore's module design & manufacturing facility in Dyce, Aberdeen completed the project within a tight timeframe to deliver a high specification, single lift 15m x 5m x 4m J30 fire rated/blast-rated Zone 2 VSD Module.

The module, weighing 85 tonnes, will be installed on the 'Aoka Mizu' Floating Production, Storage and Offloading (FPSO) vessel currently undergoing an upgrade and life extension works in Dubai. The vessel is planned to be used as a host facility for Hurricane Energy plc's Early Production System development of the Lancaster field, west of Shetland.

The module contains HV switchgear, VSDs, associated control equipment and utilities for the Electrical Submersible Pumps (ESP) which will be installed in the production wells, to provide artificial lift.

The seven-figure contract involved OEG's specialist design & manufacturing team carrying out all structural & outfitting activities, mechanical installation of equipment, electrical wiring and termination of both variable speed drives and the high voltage switchgear. The module structure was specifically designed and prepared to allow a third VSD to be installed offshore in the future.

Over 140 kW of cooling will be installed on the top of the module roof to control the heat generated from the drives and switchgear.  The module includes a fire suppression system, duty & standby pressurisation system, ProfiBus management system and FPSO interface hook-up junction boxes, all housed in a weather-protected recessed area of the module.  Other safeguards include J30 (Jet fire rating) side and end walls for high-level personnel & equipment protection.

Bluewater's Project Engineering Manager - Reinout Maitland commented: “The VSD module is an important part of our client's field development strategy and is a critical element to our project planning. OEG's extensive modular solution experience provided strong and adaptive performance for timely delivery of the VSD module.  This successful contract execution illustrates our collaborative approach with our suppliers to provide cost-effective and efficient technical solutions for safe and quality-focused project delivery.”

Dave Hunter, Operations Director of OEG said: “Securing and completing this project within a very tight schedule has been a positive start to 2018. The VSD module has been expertly outfitted including the full integration of the client's free-issue equipment. OEG has developed an international reputation for quality, safety and providing cost-effective offshore modular solutions for our global customers and particularly our expertise in this specialist area of equipment rooms.

OEG technicians will be on-site in Dubai to support Bluewater with the final installation and commissioning of the module on the FPSO before it leaves for the Lancaster field.
