Van Oord’s new offshore installation vessel Boreas has been launched at the Yantai CIMC Raffles Offshore Ltd. shipyard in China. The Boreas’ dual-fuel engine set is able to run on methanol and is purpose-built for the transport and installation of the next generation foundations and turbines at offshore wind farms. Commercial availability is expected in 2025.
Upon completion, the Boreas will be the largest vessel of its kind. Because of its size, the launch was a challenging job. First, it had to be moved from the construction site to the quay, using the so-called “skidding method”. Skidding is a safe and efficient load-out method for the horizontal transport of heavy and oversized objects along a linear track. The vessel was then skidded from the quay onto two pontoons. These pontoons were later submerged in a controlled operation after which the Boreas became afloat.
After safely being moored alongside, the works on the Boreas will continue with the installation of the main crane and the extension of the legs of the jack-up vessel. Meanwhile the vessel’s technical installation will be further commissioned, after which sea trails will take place to test performance. Subsequently, the Boreas will be handed over by the shipyard to Van Oord.

Giant vessel, fewer emissions
The Boreas is preparing Van Oord for the increase in scale in the offshore wind industry. The vessel measures 175 metres in length and has a crane with a 155-metre-high boom, able to lift over 3000 tonnes. Four giant legs, each measuring 126 metres, allow the vessel to be jacked up and work in waters up to 70 metres deep. It will therefore be able to install the next generation of 20 MW offshore wind turbines at sea.
Being an example of the energy transition within Van Oord, the Boreas is the first of its kind to be able to run on the future fuel methanol, reducing the ship’s carbon footprint by more than 78 per cent. In addition, the vessel will be equipped with a cutting-edge active emissions control technology (selective catalytic reduction) to reduce the NOx emission to an absolute minimum. A battery pack of about 6000 kWh can take peak loads and regenerate energy to reduce the fuel consumption and corresponding emissions even further.
