Damen Completes Delivery of Floating Pump Station Sauger III

Hamburg Port Authority (HPA) has taken delivery of the Sauger III, a custom floating pump station built by Damen Shipyards Group, for supporting dredging operations.

With the 37 meters in length and 10 meters wide, the station features a powerful, dual pump installation and comfortable accommodation for the crew.

The Sauger III was built to a completely new design following a European tender process that began with ten yards and was finally won by Damen. The order was placed in December 2014 and the vessel built in 15 months at Damen Shipyards Hardinxveld.

The structure is essentially a pontoon fitted with sophisticated pumping equipment capable of managing very large volumes of sediment. The core equipment consists of two pumps each connected to an arm on deck.

One of these pumps takes the contaminated mud from the barges that come alongside to offload and then pumps it ashore via a floating line. The second pump/arm combination adds sea water to the mud to keep it in a liquefied state. The sediment is cleaned as it passes through the pumping apparatus, allowing to be safely dumped or used for a variety of purposes.

Damen Dredging Equipment built the dredge pump using the same molds as previously used by the Hamburg Port Authority. For the jet pump a standard Damen design was used. The station is moored against piles and so does not have an independent propulsion system.

The entire operation requires a crew of just two men, and is managed from a state-of-the-art pump control room. It is powered by electricity supplied via a shore connection with a transformer that converts it to the 690v and 400v necessary for the pumps.

The Sauger III is now undergoing commissioning and trials and will begin operations after the summer.
