FLEXIBLE OFFSHORE JACKUP SERVICE & MAINTENCE VESSELOpen or Close
The vessel is designed for supply and maintenance works of wind energy plants offshore. Therefore it is a self propelled unit with DP-2 capability. For crane work an offshore heavy-lift crane with a capacity of 400 to is arranged at the portside aft. To ensure safe crane operation during installation the vessel is equipped with a high performance, double acting jacking system with four (4) tubular legs. The jacking unit of the aft leg on port side is located inside the crane foundation.
The vessel is able to maintain wind energy plants consisting of nacelle, hub and blades. In jacked up condition the vessel is a stable working platform for safe operation of the crane and the deck load. The crane can also be operated with full load in floating condition so that jacking in the harbor is not necessary. Therefore the vessel has a high performing ballast system also.
SPECIAL LIFTING DEVICE FOR TRAINSOpen or Close
The specialists of HeavyLift@Sea designed a dedicated lifting tool for the transport of six trains. Each train consisted of two parts which were connected by a hinge. Main challenge was to control the movement of that hinge. Each train has a weight of abt. 70t and a length of abt. 35m. Because of the length and the hinge, a special connection-device for two identical spreader beams was designed and delivered by HeavyLift@Sea.
Additional lifting frames for the trains were also designed and delivered by HeavyLift@Sea. All the equipment is classified by Lloyd's Register (LR). The whole job from first enquiry until loading of the trains was done in the very short time of three weeks. The lifting job itself was done by one of the the world leading Heavy Lift Ships of company SAL-Heavylift.
