Minox system started on the world’s largest FPSO

- The start-up has been successful and the system has measured results far below the required 10 parts per billion oxygen in the injection water. Again we have proven our ability to deliver effective systems for removal of oxygen from injection water, says Hans Evald Henriksen in Grenland Group.

The deoxygenation system is fabricated at Grenland Group’s yard in Tønsberg and then transported to Korea for installation at the FPSO. Agbami, with Chevron as operator, is now producing oil about 110 kilometers off the coast of Nigeria. The FPSO will inject water and associated gas for reservoir pressure management.

Interest in Grenland Group's Minox deoxygenation system comes in response to several factors. With the current tight energy market, more oil companies are considering water injection in the reservoirs for enhanced oil recovery. Many of the projects are in deeper water where the compact and lightweight modular system lends favorably to platform structural limitations.

In addition, the Minox system is both environmentally friendly and flexible with regards to design and oxygen removal capacity. The oxygen is removed from the injection water in order to reduce corrosion in equipment and pipe systems, and to prevent growth of unwanted bacteria in the oil reservoirs.

So far, about 30 Minox systems have been delivered to installations in the North Sea, USA, Brazil, Mexico, Malaysia and West Africa. The Minox technology from Grenland Group is unique since the oxygen level in the water is efficiently removed without the use of chemicals. The systems are also very compact and lightweight compared to systems from other suppliers.

Minox Technology, based in Notodden, was acquired by Grenland Group in 2006.
