As activity across the upstream sector accelerates, demand continues to grow for reliable, locally supported marine infrastructure that keeps complex energy projects safe and on schedule.
InterKonstruct, the marine service arm of Konstructum Contracting Company Limited (KCC), a Nigerian-owned energy and infrastructure investment holding company, addresses this operational need through its fleet of two accommodation support barges, the African Lifter and African Fjord.
Together, the vessels provide accommodation for up to 700 personnel, alongside significant heavy-lift and deck capacity to support a wide range of offshore operations.
Renewed investor confidence, recent regulatory reforms, and an industry push to convert development licenses into producing assets are driving higher field activity across Nigeria.
Brownfield maintenance, greenfield development, and offshore decommissioning campaigns depend heavily on specialized marine assets capable of housing workforces, staging heavy equipment, and operating in shallow or swamp environments where conventional vessels face operational limits.
Interkonstruct serves this specific market need. Operating as a joint venture between Interoil Services Limited and Konstructum Marine Services Limited, the company combines more than two decades of Interoil industry experience with the project execution capability of Konstructum to deliver targeted marine support focused on safety, efficiency, and operational performance.
The asset portfolio features the ABS-classed African Lifter, built in 2009, which provides fully air-conditioned accommodation for 400 personnel, a 950-square-meter deck with 10-tonne-per-square-meter load strength, a 38-tonne crawler crane, a 25-tonne pedestal provisions crane, and an S61N-compliant helideck. Operating alongside it is the ABS-classed African Fjord, built in 2008, offering accommodation for 300 personnel, a 1,600-square-meter deck with 15-tonne-per-square-meter load strength, a 75-metric- tonne pedestal crane, and an AS 332 L2-compliant helideck.
Both support barges meet ILO 92 and IMO Resolution A468 (XII) accommodation standards and feature eight-point mooring arrangements along with integrated firefighting, lifesaving, and navigation systems. These combined technical specifications enable both vessels to execute floating construction, hook-up and installation, shutdown maintenance, and decommissioning work in shallow-water fields.
‘Controlling owned, asset-backed marine capacity gives operators the schedule certainty and operational confidence required to execute complex offshore campaigns,’ said Abayomi Awobokun, Director at Interkonstruct.
‘By delivering accommodation, heavy-lift capabilities, and technical execution through a single integrated interface, we reduce interface risk for our partners while directly supporting the national drive to scale energy production in shallow-water and swamp environments.
‘Looking forward, Interkonstruct plans to expand its operational footprint by adding platform supply vessels and client-tailored assets to its portfolio, broadening its support capabilities across both shallow-water and deepwater offshore operations” He added.
