Construction of Subsea 7鈥檚 state-of-the-art new 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 (HHI) in South Korea, is being readied for the installation of key capabilities including a 600 t vertical lay system (VLS) and a 900 t crane.

Both the 600 t VLS and 900 t 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鈥檚 specifications is a unique knuckle boom rope-luffing crane which can operate in a series of configurations, with capacity of up to 900 t. When combined with the 600 t VLS, deck space of 2600 m虏, two work-class ROVs and a 7000 t 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 unique 900 t crane, with its combination of flexibility and capability, offers many different operational modes, which can be selected for 900 t, 600 t, 300 t, and high-hook operations.

Dr Stuart N Smith, Vice President Asset Development at Subsea 7, said that the Seven Arctic will advance subsea construction capabilities, particularly in ultra-deepwater fields, which pose increasingly technical challenges.

鈥淭his vessel offers our clients the opportunity to install larger, heavier infrastructure components more efficiently and effectively,鈥� he said.
