Cranes help assess water quality and deal with unexploded bombs
A novel application for Palfinger marine cranes can be found on board the ‘Haithabu’, a new water body monitoring ship for Schleswig-Holstein’s government-owned Company for Coastal Protection, National Parks and Ocean Protection.
The small Kiel-based vessel is equipped with several cranes, including two from Palfinger Marine, a PK 23500 M and PK 40002 M. It is powered by two Volvo engines, each rated 441kW, and fitted with a urea injection system for low NOx emissions.
As well as water body monitoring, the ship laboratory is used to measure the oxygen content of water samples, determine the quantities of plankton and several other tasks. But in addition, the vessel is equipped for a novel application – clearing unexploded bombs, sea mines, discarded ammunition and other dangerous materials from WW2 which are frequently found along Germany’s Baltic coastline. The ammunition is defused by divers from the bomb squad, and the Palfinger cranes provide the divers with the necessary tools and material so that they can safely defuse the dangerous debris, and bring the items onboard for safe disposal. Another application for the Haithabu is combating oil spills, using booms positioned with the PK marine cranes.
Of the cranes, the smaller PK 23500 M is installed on the port side, and is normally used to position the gangway and move material on deck. Its can lift a maximum of 10,000kg with a working pressure of 300bar and a range of 18.8m at a deadweight of 1,720kg. The larger PK 40002 M is installed on the starboard side and is used for heavier jobs. It is designed for maximum manoeuvrability with a lifting capacity of 13,106kg at a dead weight of 2,920kg, and maximum range of 24.8m. The crane allows for continuous 360° rotation.
The current Haithabu was built at the SET shipyard in Tangermünde and replaces the old, smaller Haithabu, which is now to be sold.
