Swiss power and automation firm ABB has delivered four Azipod C propulsion systems to be installed on the Blue Ocean II wind turbine installation vessel being built by South Korea’s Samsung Heavy Industries (SHI).
The order follows a similar scope from Samsung Shipyard for the first Blue Ocean wind turbine installation vessel.
Upon installation, both vessels will be delivered to Singapore-based offshore oil and gas industry service provider Swire Pacific Offshore (SPO).
ABB’s new Azipod C plant in Shanghai, China, will deliver a total of eight Azipod C propulsion systems for the two vessels, which will save space inside the vessel hull for more efficiency in ship design and equipment placement.
The propulsion system will help reduce the Blue Ocean vessels’ fuel consumption by 25%, as well as improve their manoeuvring capabilities.
The improved manoeuvrability will help the vessels operate in a wider weather window, offering more flexibility in the transportation and installation of offshore wind foundation materials and turbines of all types and sizes.
Both vessels feature a usable deck area of 4,000m², DP 2 station keeping, a 1,200t crane, a total jackable weight of 8,400t and a transit speed of 13 knots.
SHI delivered Pacific Orca, the world’s largest wind farm installation vessel (WIV) to SPO in July 2012 to provide services for Danish utility company Dong Energy.
Pacific Orca has a length of 161m, breadth of 49m and depth of 10.4m, and is capable of transporting and installing 12 units of 3.6MW design to a depth of 60m.
The vessel can be floated up to 17m above sea level using its six jack-up legs, and the 1,200t crane fixed on the vessel allows the installation of power generation towers, power generation rooms and wings.
