Knud E. Hansen continues to construct on its portfolio of revolutionary designs and intensive expertise within the offshore wind farm sector with a brand new platform: The ATLAS C-Class. Named after the Greek Titan tasked with holding up the sky and heavens above, this platform boasts unparalleled energy and sturdiness.
With a jacking deadweight of 18,00zero tonnes, 6,800 sq. metres of cargo deck space and a Three,00zero tonne @ 37 metre crane, it’s at present the one WTIV able to carrying six of the new-generation 14-16 megawatt wind generators, and a minimum of 5 of the following technology 20+ megawatts generators.
The jacking deadweight and crane capability additionally allow the vessel to hold a minimum of 4 of the extra-large monopile/transition piece foundations, that are required for the 14–16 megawatts generators.
The spectacular measurement and scale of this groundbreaking design is matched by its versatility and customizable options. The ATLAS C-Class is meant as a platform which is able to type the premise for additional customization based on our purchasers’ goals. Cranes, thrusters, mills and jacking methods can all be modified and chosen primarily based on producer availability such that the vessel could be tailor-made to swimsuit the person wants of every shopper. This represents a big departure from rivals that provide off-the-shelf merchandise with little flexibility.
Platform particulars:
• Length Overall (excluding helideck) 170.00 metres
• Breadth, moulded 60.20 metres
• Depth to Main Deck 13.20 metres
• Draught, moulded @ 18,00zero t deadweight 6.70 metres
• Speed @ 6.50 m draught incl. 10% s.m. 12.zero knots
In preserving with the target of design versatility, the cargo deck incorporates uniform girder spacing in each longitudinal and transverse instructions such that foundations for tools and turbine components could be standardized and put in in many alternative areas and orientations.
Energy financial savings and low emissions have been key drivers for the propulsion system. The vessel is powered by eight similar mills, every with Three,340 kilowatts energy, that are organized in two impartial engine rooms. A DC grid system permits the engines to run at variable velocity for optimum gas effectivity. The DC grid system is coupled to a four megawatt battery pack for load leveling and peak shaving.
To additional reduce energy consumption, the vessel is supplied with a few of the most effective thruster models in the marketplace. This contains 4 azimuthing stern thrusters, pushed by extremely environment friendly permanent- magnet motors and geared up with nozzles for optimum bollard pull. At the ahead finish, there are two tunnel thrusters and two retractable bow thrusters configured to maximise thrust. The platform is supplied with 4 Three-chorded trusswork legs which might assist it in water depths as much as 80 metres.
The spud cans are optimized for the bottom potential seabed penetration, and they’re fitted with buoyancy containers to cut back the draught in port, cut back the load on the seabed when the vessel is jacked up, and to assist retract the legs out of muddy sea beds. The platform is elevated by a strong high-speed electrical rack-and-pinion jacking system designed for five,00zero load cycles.
The three decks above embody a complete of 130 cabins for contractors, crew and officers. The prime deck consists of a bridge with centerline and wing consoles and a big helicopter deck. Below the primary deck is a gymnasium, cinema, TV room, video games room, and sauna in addition to a laundry room and retailer rooms.
The ATLAS C-Class is the primary in a collection of deliberate WTIV platforms of various sizes. One of these already underneath improvement is a smaller A-Class platform that may carry 4 14 megawatt generators and is supplied with a 1,600 tonne crane for purchasers who require a smaller variant to put in wind generators on pre-installed foundations.
