ROTOR Supplies Electric Motors for Deep Water Construction Vessel Aegir

A Deep Water Construction Vessel, built in Korea and the Netherlands, will use electric motors from Rotor in The Netherlands on the critically important barge mooring and anchor winches.

The DCV Aegir, named after, Norse god of the sea, is a giant mono-hulled vessel capable of executing complex infrastructure and pipeline projects in ultra deep water. It also has the lifting capacity to install fixed platforms in relatively shallow water, along with a fast turn of speed and the facilities to accommodate a crew of 300 in comfort. As such it will be one of the most capable and modern vessels in its class and able to undertake projects that were previously considered impossible.

Rotor is a manufacturer of standard and special motors, supplying industry with IEC- and DIN specifications motors up to 1000 kW. As a global player in the marine engineering industry it is registered with all the shipbuilding classification bureaus. It can build complete drive systems to clients’ specifications for a variety of applications, such as pumps, ventilation systems, davits, cranes, port machinery, hydraulic systems, compressors and various other pieces of equipment.

Rotor is part of the Regal Beloit family of companies, one of the largest motor manufacturers in the world.

For the anchor winches Rotor motors type 5RN315L06 200kW IC410 were selected. These are of cast iron construction and three phase operation. These motors provide all the anchor movements of the ship. For the barge mooring winches, slightly smaller 5RN315L06 190kW IC410 were specified and fitted with bespoke braking and control systems.

The DCV Aegir, has been under construction since 2011 and includes a main crane, deck space for three giant pipe reels, a RJ-lay tower with deep water A&R system, two auxiliary knuckle boom cranes and many other specialised systems for offshore construction work.

The vessel is expected to start his first work in the fourth quarter of 2013. It will have a payload of 4,500 metric tonnes, a lift capacity of 4,000 metric tonnes and be capable of laying pipes to a depth of 3,500 metres.

The MS Aegir is being built for Heerema Marine Contractors, a world-leading supplier to the offshore oil and gas industry. HMC transports, installs, and removes all types of offshore facilities and operates some of the largest crane vessels in the world.
