Construction

Ariosh draws on construction professionals with an average of over 25 years vast experience and world-class fabrication facilities to handle multiple projects for the delivery of onshore modules, offshore platforms, deepwater floating platforms and subsea facilities. Our process entails detailed pre-construction and constructability planning that ensures the most efficient construction approach throughout the project and completion-driven tools that promote schedule certainty, safe execution, cost effectiveness and reliability, even in the most challenging environments.

Our fabrication assets and the ability to load out and ship completed projects by water and road enables Ariosh to support our clients' onshore and offshore projects. Our experience and processes assist us in providing HSE assurance, quality assurance, structural integrity assurance and on-time delivery.

Construction Management

Ariosh construction management services extend throughout the project lifecycle. We engage all project stakeholders from initial site studies and preconstruction planning through commissioning and start-up, using our detailed planning, project controls and tools to achieve stakeholders project objectives.

Fabrication

Ariosh is the fastest growing indigenous fabrication contractor in Nigeria today with proven track record of piping spools prefabrication, piles & decks fabrication, boat landings, subsea jumpers and other small structures. We are fast becoming industry leader in heavy fabrication such as offshore jackets, process modules, bridges, pressure vessels, subsea manifolds & control modules, suction piles, jumpers, mudmats etc.

We have expertise in welding of various steel including large bore piping (carbon steel, carbon steel cladded inconel and duplex) and small bore piping (stainless steel, inconel and duplex) using a wide range of process including: SMAW, Orbital Welding, TIG and SAW.

Fabrication Yard Locations

Strategically positioned along Aker road, Rumuolumeni, Rivers state, to provide fabrication services and onshore marine logistics to our clients, Ariosh's fabrication yard and onshore marine base has a combined area of 120,000 square meters with a 200-meter long 8-meter draft waterfront. The 200 meters long quayside is along the Bonny River, which enables us to load out large structures for installation offshore. The planned capacity for the yard is 2 million hours of fabrication work per year with annual throughput of approximately 20,000 metric tons.
This yard is located at Nigerian Naval Dorkyard (NND) in Victoria Island Lagos. The facility has a combined area of 15,000 square meters dedicated to Ariosh for welding, storage, laydown, blasting and painting activities, which can be expanded to accommodate more work on a case-by- case basis. The facility is capable of producing about 8,500 metric tons of steel fabrication annually.
