Engineering group Tebodin has been awarded three contracts on offshore and refinery projects in Abu Dhabi, according to a source familiar with the schemes.

The Netherlands-based company will carry out a study for Abu Dhabi Marine Operating Company (Adma-Opco) on the replacement of critical piping systems on Das Island oil and gas facilities.

The facilities on Das Island include oil and gas processing, storage and export facilities, utilities, and power generation, some of which have ageing piping systems.

Tebodin’s study will be carried out in several phases, with 10 critical lines recommended for phase one of the project. The initial stage is expected to be completed in the fourth quarter of 2015.

The Dutch group has also been awarded a front-end engineering and design (feed) for Abu Dhabi’s other major offshore operator Zakum Development Company (Zadco).

Zadco plans to build a new substation next to the existing service area substation on Zirku Island to accommodate a new transformer and low-voltage switchgear.

Tebodin was appointed as the feed contractor after successfully completing a study on the project for Zadco.

The engineering group has also won a contract from Abu Dhabi Oil Refining Company (Takreer) to provide consulting services for study of the electrical system at the refinery site in Ruwais.

During the expansion of the general utility plant (GUP) – which powers the entire Takreer complex – and refinery plants, electrical system studies were carried out considering the unit expansions individually.

However, due to power failures in certain facilities, Takreer is now planning a comprehensive system study.

The scope includes electrical data collection validation, modelling the network data, data entry and conducting the power system studies for the complete network of Takreer in Ruwais.
