SINGAPORE – Nakilat-Keppel Offshore & Marine (N-KOM), a joint venture between Qatar’s Nakilat and Keppel Offshore & Marine (Keppel O&M), has delivered its first liftboat to Qatari contractor Gulf Drilling International.
Al Safliya, built to the ORCA 2500 design developed by Keppel subsidiary Bennett Offshore, is also the first liftboat wholly constructed in Qatar, in this case at the Erhama Bin Jaber Al Jalahma shipyard.
Al Safliya has four tubular legs, a 200-metric ton (220-ton) leg encircling crane and a 50-metric ton (55-ton) pedestal crane, an open deck space of around 800 sq m (8,611 sq ft), a helideck, and accommodation for 130 persons.
It can perform services ranging from well servicing, commissioning, and maintenance to decommissioning of offshore platforms. A gangway bridge can be used for emergency and other safety purposes.
Bennett Offshore has developed other liftboat designs (such as the ORCA 1500 and ORCA 3500) with varying operational and accommodation capacities to suit different requirements.
According to the joint venture, liftboats offer numerous advantages over traditional non-self-propelled and self-elevating units. They can mobilize without the assistance of support vessels making them suitable for a variety of shallow-water offshore operations.
By customizing liftboats with different tonnage cranes on deck, they can handle maintenance of most shallow-water oil and gas fields, as well as workover drilling and well intervention tasks.
In addition, the self-elevating is said to provide a stable and efficient work environment by raising the working areas above the influence of wave action.
