Crane upgrade for Sea Installer

Its primary focus will be to upgrade the 132m A2SEA-owned vessel’s main crane to increase lifting capacity.

The Sea Installer arrived at DSAm on 10 April and took its position alongside lay-by berth number one. The project is facilitated by the prefabrication of key components at nearby Niron Staal Amsterdam, also part of Damen Shiprepair & Conversion.

“We need to remove a total of 569 tonnes from the vessel and lift a further 702 tonnes back on board again,” explained Daniel Gerner, Damen project manager.

DSAm has created a temporary lifting and storage area alongside the vessel’s berth to accomplish the notable lifting procedures safely and effectively.

The yard will use an LR1600-2 Mammoet crane to perform the lifts and the preparations also included calculating the numerous lifting plans.

With the vessel’s Boom, Boom rest, A-frame, winch and hook block pockets already removed from the vessel, operations are in full swing.

Mr Gerner continued: “We have divers currently in the water to inspect the spud cans – and we are also replacing one of the jacking cylinders.”

“We are looking at finishing this considerable project within a 2-month timeframe. The strong winds that we had here during the first couple of weeks have set us back a bit, but we are still on course for timely completion. If necessary, we can ramp up our work schedule by moving to 24/7 operations.”
