An improved power generation underway as OB3 pipeline nears completion


An improvement in Nigeria’s power generation is likely soon as the Obiafu/Obrikon – Oben, usually ascribed as OB3 gas transmission pipeline is about to be completed.

Recent findings indicated that the scope for Lot B of the project is at more than 80 percent ready.

The contractor, Oilserv limited, an indigenous oil and gas engineering and construction company assured that it would complete its scope by March next year.

Its work scope includes the completion of works relating to survey verification, bush clearing, welding and backfilling of its 65 kilometre stretch of pipeline.

According to the update, Oilserv has also successfully crossed 15 major roads with width ranging from 5.02 meters to 26.73 meters through Thrust-Boring mechanism.

Using horizontal directional drilling technology, it has also crossed 2 major rivers, 642 meters of Asimiri River, and 724 meters of Ethiope River.

It is currently completing the crossing of the 1,200 metres Jamieson River. When completed, the 127km x 48-inch pipeline system with associated plant facilities will be the biggest diameter-inch gas pipeline in the country with an ullage capacity of 2 billion standard cubic feet, Bscf/d.

It was learnt that but for some project delays which included about 20 months lack of access to the “right of way”, the project would have been completed by now.

This pipeline system is a critical component of the Nigeria Gas Master Plan which the Nigerian National Petroleum Corporation, (NNPC), had been steadfastly nurturing over the past decade.

When completed, the project will totally transform the infrastructure landscape to a state that can enable domestication of natural gas demand and catalyse Nigerian’s economy into one of the most industrialised nations.

Frazimex Engineering, a member of the Oilserv group, handled the entire Engineering design, which is regarded as a plus in the drive to build local capacity in the capital-intensive and technology-driven- industry.

This is the first time the engineering design and construction of the pipeline infrastructure system of this magnitude is being handled by purely indigenous company. The Lot A part of the project is being handled by Nestoil Limited, another indigenous oil and gas company.

The pipeline system is very strategic as it would boost the availability of gas to fuel the battery of already-developed power plants, and at the same time deepen the availability of gas for other domestic needs
