"In fact, we are able to win such projects at the time everything is still on the drawing board,” explains Patrik Lowie. “The trick is to simulate and visualise all possible situations beforehand. Looking at this from a distance, one…Read more
The Sunfish and the Moonfish were indispensable for the Race Bank project. But, obviously, they were not alone.
“Export cables may look very solid, but applying too much force while pulling them is absolutely advised against. To be able to pull the cable ashore from the cable-laying vessel, we wanted to position it very close to the coast. With its laden draught of 6.5 metre, the Isaac Newton was no option as it would get no closer than about eight kilometres off the coast. That’s why we decided to use the DN120, originally a rock installation pontoon but built according to Jan De Nul’s philosophy and thus relatively easy to convert into a cable-laying platform on the one hand and a transport and control platform for the Sunfish and Moonfish, which would subsequently dig in the cables, on the other. We succeeded in bringing the DN120 up to two km off the coastline, just outside the vegetation area. As such, the DN120, the Sunfish and the Moonfish bridged the distance from the coast to where the Isaac Newton could take over, about eight kilometres off the coast.
Patrik Lowie: “We cleared the entire deck of the DN120 and installed the necessary equipment. A large carousel for winding and unwinding the cable, an automated anchoring system to enable the DN120 to move in a straight line, a system for the remote control of the Moonfish because also the operators controlling the Moonfish through a so-called ‘control umbilical’ operated from the DN120. Bear in mind that the Moonfish is an amphibious but semi-submersible vehicle working half the time below water. On the Sunfish, operators could stay on board, on the Moonfish this was never an option."
“We are a work in progress, getting better by the day,” says Rutger Standaert. On his business card, he carries the title of ‘Technical Superintendent New Building Design’ or, in short, one of the naval architects at Jan De Nul.…Read more
