Cranes for OSS Nordergründe, Merkur and Hohe See
HMB Lintec marine signed contracts for the supply of pedestal offshore cranes for three substations located in German waters, namely for the wind farms Nordergründe (18 turbines, 111 MW), Merkur (66 turbines, 396 MW) and Hohe See (71 turbines, 497 MW). Substations are an essential component of offshore wind farms and serve an important function: to stabilize and maximize the voltage of power generated offshore, reduce potential electrical losses and transmit electricity to shore.
Today’s substations consist of a topside or a deck installed on monopile or jacket structures. Serving as an offshore power-converter station, a substation’s platform may be equipped with boat landings, a helicopter deck, accommodations, and act as a logistics’ service base during installation and operation of an offshore wind farm. The cranes installed onboard the platforms are particularly important in order to safeguard the logistics of material and persons from sea to platform and vice versa.
All three cranes are certified and built under the supervision of the DNV GL. The main cranes are pedestal cylinder luffing type and designed according to EN 13852:1 norms. All cranes are equipped with AOPS/MOPS, Constant Tension System and man-riding functionality.
The pedestal crane on substation Nordergründe, situated close to the German coast, is capable of lifting material up to 15t at 18m outreach. Merkur´s DolWin3 substation will operate a HMB Lintec marine crane operating loads of 8,5t at 29m outreach. Wind farm Hohe See will be connected to the German high voltage grid via the substation BorWin3. The substation will be equipped with a HMB Lintec marine crane of SWL 17t at 25m outreach. Additionally HMB Lintec marine delivered various smaller cranes for man riding e.g. 2t SWL on 5m and service cranes for servicing the machinery onboard the platform. HMB Lintec marine supplies customized cranes from design to installation and commissioning. In order to ensure further product development and support clients’ demands for customized cranes Lintec marine teamed up with crane manufacturer PROTEA in the area of engineering, production, testing and sales. PROTEA maintains a production in the South of Poland employing 120 people at any time.
Together HMB Lintec marine and PROTEA hold extensive expertise and enjoy a vast number of references for the shipbuilding and offshore industry. In the wind energy sector HMB Lintec marine auxiliary cranes can be found on various jack-up and service vessels. Notable references are the jack-up vessels Thor, MPI Enterprise, M/V Torben or Vidar.
