The 12-month contract will be serviced by Harkand's two DSVs, the Harkand Da Vinci and Harkand Atlantis, supported by project management and engineering from Harkand's Aberdeen office.
The contract covers well tie-ins, structure installation, piling, flexible flowline lay, flexible riser installation, pre-commissioning, riser recovery, decommissioning and general inspection, repair and maintenance work.
"This contract win is a further acknowledgment, not only of the expertise and capacity we have built up within the region, but also the open culture that we have at Harkand," the firm's Europe managing director David Kerr said.
"We look forward to delivering a consistent and cost efficient service to Maersk, which is especially critical in today's business environment.
"By using both our sister DSVs, we will provide a robust and fully flexible approach to executing both planned and unplanned interventions and we will work closely with Maersk to ensure safe and successful campaigns."
The Harkand DaVinci and Harkand Atlantis are both equipped with state-of-the-art saturation diving systems, 140 tonne active heave compensated cranes and Super Mohawk ROV spreads.
The London-based Harkand provides offshore vessels, ROVs, diving, survey services, project management and engineering to the oil and gas and renewables industries.
