The semi-submersible installation vessel ‘Alfa Lift’ is one out of three nominees for the OSJ Offshore Renewables Award 2020. This award goes to a company, project or product that has made a significant contribution to the development of the offshore renewables market during 2019.

The ‘Alfa Lift’ has been designed by Ulstein for Offshore Heavy Transport (OHT).

The vessel is regarded as the most innovative, custom-built offshore wind foundation installation vessel in the world thanks to the combination of operational modes and technical features. Its game changing design contributed to OHT having been selected as preferred supplier for the transport and installation for the world’s largest offshore windfarm, Doggerbank.

Why is the Alfa Lift so special?
The Alfa Lift vessel will be performing transportation and installation of foundations for offshore wind farms. The flexibility inherent in its design opens up the possibility to carry out heavy transportation, installation and decommissioning activities in other markets. What makes this dynamically-positioned, 48,000 DWT vessel truly exceptional is the ability to perform heavy lift crane operations with the main deck submerged. Targeting the offshore renewables market, the vessel naturally has been developed to reduce environmental emissions as much as practicably possible. In addition to the installation of exhaust gas scrubbers, the engines are Tier III compliant, and a battery package will contribute to the reduction of the overall fuel consumption and resulting emissions.

The vessel’s capabilities match the future requirements of the offshore wind industry, allowing her to transport and install up to 10 x 1,500t ultra-large jacket foundations or 11 x 2,000t XXL monopiles plus transition pieces for the largest anticipated Wind Turbine Generators. The vessel is currently under construction at the CMHI yard, China, and is planned for delivery in 2021. OHT has options for up to three additional units of the same design at the yard.

The winner of the OSJ Offshore Renewables Award 2020 will be announced on 5 February.
