Signing of the Contract for the building of a Self-Elevating Wind Turbine Installation Vessel 4.000 T; “VOLTAIRE” with COSCO (NANTONG) SHIPYARD CO., LTD.

Original delivery time DECEMBER 2021. Due to Force Majeure caused by Covid 19 the delivery time will be postponed.

Signing on APRIL 5, 2019 in Luxembourg contract between JAN DE NUL and COSCO NANTONG for the building of the largest Wind Turbine Installation Vessel in the world.

The VOLTAIRE will be the first Offshore Jack-Up Installation Vessel on the market, able to transport, lift and install the ‘Next Generation’ offshore wind turbines and its ever larger foundations. The vessel will have better operational limits compared to the existing Jack-Ups. The larger deck space will also enable to optimize installations at sea and to lower the fuel consumption and emissions. But not only will this vessel be ready for the future of offshore renewables, it will also be deployable for the oil and gas industry, and for decommissioning of offshore structures. All these activities will be performed in a sustainable way thanks to lower fuel consumptions and emissions through Jan De Nul’s in-house developed ULEv technique (Ultra Low Emission vessel).

Ground-breaking: the VOLTAIRE will be the very first seaworthy EU Stage V-certified offshore installation vessel with ultra-low emissions in the world. The VOLTAIRE is equipped with a main crane of over 3,000 tonnes and a DP2 system. The vessel has an operating depth of over 80 meters, a payload of about 14,000 tonnes and accommodation for 110 persons. With her four legs, the Voltaire can lift itself above the sea level for stable working conditions. She will be delivered in 2022.

What happened in 2020?

For everybody of us 2020 was an exceptional and unexpected year. A virus came to us and suddenly we were living in a different world.

As a direct consequence our customers and we had to adapt our activities. Our last business trip to South-Korea for new projects dated early February. As further face-to-face contacts were impossible everything has been put on hold by our customers.

What will happen in 2021?

With the hope that within the next few months business life will come back to normal, together with our customers we will continue working on new projects for hopper dredgers, split barges and offshore equipment. We also expect to revamp the production of parts and other dredging equipment in China. We are very well aware of the fact that our friends in Dalian, Shanghai, Busan and Haiphong, Da Nang or elsewhere are waiting for our good news.
