Trailing Suction Hopper Dredger Drydocked at Kooiman

The 6,000-cubic-meter trailing suction hopper dredger Reimerswaal was moored for regular maintenance at the end of December 2015, alongside the jetty of Scheepswerf Gebr. Kooiman BV in Zwijndrecht.

The Reimerswaal, having an overall length over of 130.25 meters and a (molded) width of 22 meters, was built in 2012 by Kooiman for Reimerswaal Dredging / Den Herder.

Among others, Kooiman carried out maintenance works on the dredge- and dry unloading installations. Several components exposed to heavy wear and tear have been repaired or replaced.

In addition, in the dredge pipe system, new wearing plates have been installed. Since the suction pipe connection normally is under the water line, the fore ship has been lifted sufficiently to get the inlet above water allowing required repairs.

The fore part of the vessel has been lifted using the propeller repair dry dock of shipyard Kooiman. Despite the fact that in principle the vessel is too wide for this drydock, the operation was executed with success by only bringing the forepart inside the drydock and lifting her as such.

In addition to the 150-meter-long repair / outfitting jetty, Kooiman shipyard is equipped with two longitudinal slipways and two propeller repair dry docks of 19-meter-wide, having a lifting capacity of 1,000 tons.
