EPCI SURF

Delivering efficient subsea solutions from seabed to surface

We provide full range subsea services and hold strong EPCI (Engineering, Procurement, Construction, and Installation) expertise within the SURF (Subsea structures, Umbilicals, Risers, Flowlines) division. With rapidly increasing demand in the Nigerian SURF market, we continue to evolve and expand in capacity and operations to be able to meet the demands and challenges of the West African subsea field development domain.

Subsea, Umbilicals, Risers, and Flowlines

As new reserves are found in deeper water and more challenging environments in Nigeria and other West Africa sub-region, the scale and complexity of SURF (Subsea structures, Umbilicals, Risers and Flowlines) projects continue to grow.

Our strategic partnership alliance with world-class SURF Installation Companies enables us to deploy best-in-class construction vessels that are cost effective for our subsea installation projects. With our partner’s assets and global expertise in SURF Installation and a full range of subsea services, combined with highly experienced construction management team, we deliver complex subsea projects.

Life of Field (LOF)

Producing fields demand accurate, professional inspection and maintenance services, in order to ensure the safety of oilfield workers and the environment, and to protect performing assets. Ariosh supports asset integrity throughout the operational lifecycle, offering clients integrity management, survey, inspection, repair, maintenance, remote intervention and field extension.

Through strategic partnership with market leaders in Remotely Operated Vehicle (ROV) and diving, we are able to provide full range of subsea Life of Field (LOF) services.
