of supply includes the engineering, procurement and construction of the
monopile lifting, skidding and transfer system, which is an integral part
of the installation process undertaken by employing an upending tool and
motion compensated gripper frame.
The motion-compensated gripper frame will be closely interfaced with the
vessel’s dynamic positioning and control system in an integrated solution
developed jointly by MacGregor and Kongsberg Maritime. Both companies believe
that the application of automated handling solutions will increase the
safety, productivity and consistency of the installation operation, resulting
in substantial cost and time savings.
is scheduled for delivery in 2021 and will be the world’s largest
custom-built offshore wind foundation installation vessel. She will feature
a 3,000 ton main crane, a 10,000+ m² ‘smart deck, capable of carrying
and installing up to 14 XL monopiles per voyage and will be able to fully
submerge the main deck to a depth of 14.66m.
"OHT is committed to continuously advancing the development of technologies
within offshore wind operations, thereby enabling complex operations to
be undertaken at the highest levels of safety and efficiency. The monopile
installation solution is the result of applying our collective capabilities
and experience to solve market challenges and achieve optimum operability
for our vessels," says Torgeir E. Ramstad, Chief Executive Officer.
“Whenever we ask MacGregor to solve operational challenges in the demanding
marine environment they, together with partners, demonstrate excellent
technical understanding and respond quickly. We are extremely pleased to
be working together on the exciting Alfa
“Working closely with MacGregor, we have developed an innovative solution
that improves the efficiency of foundation installation vessels by replacing
lengthy, temporary mooring processes with full DP in combination with an
integrated guidance system and hydraulic frame mechanism,” says Gunnar
Thorsen, SVP Business Concepts, Kongsberg Maritime AS.
"MacGregor is delighted to be selected to supply the mission-critical
work system for the Alfa
says Leif Byström, Head of the Offshore Solutions Division. “We have
worked intensively over several years to develop a state-of-the-art solution
that provides the most precise installation method for all monopile ranges.
We appreciate and highly value the hard work and great cooperation between
the OHT, Kongsberg Maritime and MacGregor teams that have made this possible."
van Roozendaal, President, MacGregor says “MacGregor has invested in
applying its vast knowledge of offshore technology into enabling the progression
of renewable energy, with the OHT Alfa
being an excellent example of where these advanced technologies can be
put to work. I would also like to add my appreciation of the trust that
OHT has placed in MacGregor, and equally recognise the collaborative team
effort that has resulted in the innovative monopile installation solution
Lif has been awarded its first offshore wind contract. The vessel will
be installing the 200 monopile foundations and transition pieces on Dogger
Bank B projects.
