An historical order comprises a Liebherr floating crane type CBG 350 that is going to be used on a Transshipment Crane Barge 6324 built by the Damen Shipyards Group, Germany.
The partnership between Liebherr and Damen Shipyards Group began with the delivery of an offshore crane type BOS 300T in 1985. 22 years and 109 delivered Liebherr cranes later, both businesses are successfully headed by the third generation of the company founders.
High-speed operation
The Liebherr CBG 350 is the last of five identical floating cranes for Damen-built transshipment barges. The new crane barge 6324 was designed by the two companies, together with Van der Leun (electrical systems), DMT Marine Equipment (winches) and Pon Power for the generator sets. They are specifically designed for working from ship-to-ship, ship-to-barge and ship-to-quay.
Installed on an 18-metre-high pedestal, the CBG 350 is able to load and unload vessels up to Panamax and Cape size class. It can be equipped with a grab for dry bulk handling, a container-spreader or a hook to enable every kind of material and cargo handling.
Designed for high-speed, continuous operation, even in challenging conditions, the high stable four rope grab crane ensures an increased turnover of more than 1 000 tonnes per hour. The extended cabin offers optimum visibility during operation and optimises the efficiency of the crane handling. The CBG 350 has a maximum capacity of 45 tonnes in hook operation and 35 tons in grab operation, both at a maximum outreach of 36 metres.
Pontoon series
The barge design is based on Damen´s renowned Stan Pontoon series. The barge has a total length of 63 metres and a beam of 23 metres. It can be used for a wide variety of operating scenarios at open sea, coastal or inland (sheltered waters). It offers accommodation for 12 crew members.
Four double drum winches manoeuver the barge alongside any vessel or quay and can also be used for anchoring. The winches are positioned in such a way that they enhance safety during mooring operation and minimise the potential for hazards. The integrated ballast system trim and stabilise the whole barge construction in operation.
The planned barge concept is designated for grain handling in the Black Sea.
