Dutch overseas setup company Heerema Marine Contractors stated Monday its semi-submersible crane vessel had actually gone across the Storebaelt Bridge, called the ‘entrance to the Baltic Sea.’
“This crossing is the first time a Heerema crane vessel has accessed the region and is the result of innovative crane alterations to enable passage below the bridge. While ballasted down to Thialf’s maximum draught the total air draught was just under 65 m with the A-frames down,” the firm stated.

When Thialf was tied in the Port of Rotterdam over the wintertime of 2021-2022, the group onboard effectively performed adjustments to the vessel’s A-frames. This activity is feasible as Thialf’s A-frames currently have hingable edges that can fit the NOV custom-made semi-permanent change system. The training capability of Thialf is the same, with the vessel with the ability of raising 14,200 statistics loads, the firm stated.
Using this system, Heerema can reduce Thialf’s cranes as well as fold up the A-frames to produce an adequate air space when incorporated with ballasting in between the vessel as well as theStorebaelt Bridge

“The project has been greatly collaborative and was a Heerema Group effort as Heerema Fabrication Group’s Opole Yard completed most of the fabrication work. The team fabricated around 150 metric tons of structures required for the modification,” the firm included.
Heerema will certainly be setting up the 7,150 statistics lot Baltic Eagle Offshore Substation (OSS) in support of its customer Baltic Eagle GmbH, prior to relocating onwards to set up 27 wind generators for Parkwind’s Arcadis Ost I wind ranch in the Baltic Sea making use of its novel Rotor Nacelle Assembly (RNA) installation method.
