On 28 May 2019, Royal IHC successfully installed the enormous cutter ladder on the cutter suction dredger (CSD) Spartacus that the company is currently building for the DEME Group of Belgium.

While Spartacus is being built at IHC’s shipyard in Krimpen aan den IJssel, the cutter ladder has been assembled at its yard in Kinderdijk.

For the installation, both the dredger and the ladder where brought to the Caland Canal in the port of Rotterdam where the heavy lift vessel Aegir was waiting to be deployed for the installation.

In fact, with a record weight of 2,500 tonnes, special heavy lift equipment was needed to hoist the ladder into the dredging vessel.

The Aegir is a modern, built in 2013, deepwater construction vessel (DCV) that is owned by Heerema Marine Contractors.

It has a heavy lift crane with a capacity of 4,000 mT between 17 m and 40 m radius.

After its commissioning, which is scheduled for the end of this year, the Spartacus will be the world’s largest CSD with an astonishing total installed power of 44,180 kW.
