ALFA LIFT
A dynamically-positioned, 48,000 DWT heavy lift transport and installation vessel for the offshore wind industry. The design combines the benefits of a semi-submersible transport vessel with a large, 3,000 mt lifting capacity main crane. Can perform heavy lift crane operations with the main deck submerged.

The vessel (with options for up to another 3 units) is constructed by China Merchant Heavy Industry (CMHI) for delivery 2021/2022. 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 'Alfa Lift' will be capable of installing all types of bottom-fixed offshore wind foundations and will also transport and install topsides and subsea modules, in addition to other heavy cargoes within oil and gas.
The vessel’s crane will have a maximum lifting capacity of 3,000 tonnes at 30 metres and 1,000 tonnes at 76 metres outreach. The 216.3-metre vessel will also have a 10,000+ m² “smart deck” that can carry up to 14 giant monopiles per trip, and will be fully submersible to a depth of 14.66 metres.
Ship history
March 2019: Steel cutting
October 2019: Keel laying
November 2019: Contracted for transport and installation of foundations for Dogger Bank Offshore Wind Farm
