Crane boom extension for Wind Orca

Tuesday, December 7 2021

General – crane boom extension

In Esbjerg, Semco Maritime assists Cadeler by replacing the jib on their wind farm installation vessel Wind Orca.

In order to make sure that Wind Orca can install the largest offshore wind turbines the vessel needs a crane boom extension – from 108 to 115.2 meter by installing a new jib section.

This is a large and complex operation as the crane boom needs to be dismantled from the vessel and positioned on the Q-side.

Once the boom is on Q-side, Semco will cut and remove the tip to access old jib section, the old jib will be removed and a new prefabricated jib installed.

While the new jib is being installed, the old tip will be sent home to our own workshop for the installation of reinforcement plates.

For installation of the new jib section, a large habitat of 40m x 8m is built onsite to create the required environment for welding in high tensile steel.

Additionally, some sections of the old boom also need reinforcement in order to secure the required strength for the new and longer jib.

Furthermore, the vessel itself also need certain modifications and reinforcements is also required on the vessel to fit the modified crane boom.
