Construction of Subsea 7’s heavy construction vessel, the Seven Arctic, is proceeding on schedule with the vessel targeted for delivery in 2016.
The vessel, which is in dry dock at Hyundai Heavy Industries in South Korea, is being readied for the installation of key capabilities including a 600-tonne vertical lay system (VLS) and a 900-tonne crane.
Both the 600-tonne VLS and 900-tonne crane are currently being assembled in South Korea by Dutch heavy construction equipment manufacturer, Huisman, ready for installation later in the year.
Chief among the vessel’s specifications is a knuckle boom rope-luffing crane which can operate in a series of configurations, with capacity of up to 900-tonne. When combined with the 600-tonne VLS, deck space of 2600sq m, two work-class ROVs and a 7000-tonne underdeck basket for the storage of flexible pipe and umbilicals, the Seven Arctic will provide a step change in the management of ever more complex deepwater subsea field development projects.
The 900-tonne crane offers many different operational modes, which can be selected for 900-tonne, 600-tonne, 300-tonne, and high-hook operations.
“This vessel offers our clients the opportunity to install larger, heavier infrastructure components more efficiently and effectively,” said Stuart N. Smith, vice president asset development at Subsea 7.
