Case Studies

Block Island

Posted on September 15, 2016

Fred. Olsen Windcarrier successfully completed the installation of the US’s first offshore wind farm on 19th August 2016. There were a number of firsts for this project:

  • First offshore wind farm installed in US
  • First Transatlantic voyage for one of our vessels
  • First time our vessels have worked with feeder barges

The scope of work for Fred. Olsen Windcarrier was the transportation of five GE nacelles across the Atlantic and then installation of the full turbines at Block Island. US flagged feeder barges assisted by transporting the towers and blades from shore. The scope also included marine engineering, lift engineering, general operations planning, the design, fabrication and mobilisation of grillage and seafastening and lift supervision.

Butendiek

Posted on May 26, 2016

Fred. Olsen Windcarrier installed 80 Siemens 3.6MW wind turbines at the Butendiek wind farm between September 2014 and June 2015.

  • Implementing lessons learned from the earlier Riffgat project was identified as a key deliverable in ensuring that the project was a success.
  • Butendiek wind farm is one of the few offshore wind projects to have been constructed and commissioned on time and on budget.
  • There were no major personnel incidents during the project and Bold Tern further improved her LTI-free period and HSE record in general

Fred. Olsen Windcarrier was contracted to deliver a fully mobilised installation vessel with marine crew and crane driver, and to perform all required planning, engineering and coordination related to the operation of the installation vessel.

Global Tech I

Posted on August 31, 2014

In 2014, Fred. Olsen Windcarrier installed 75 towers and nacelles and 22 rotor stars of the 80 5MW AREVA turbines at the Global Tech I site within eight months.

  • This was the first project where Brave Tern and Bold Tern worked together.
  • Complete load out of 4 towers and nacelles in just over 24 hours.
  • New record: eight towers and nacelles installed in one week – including 10 hour transfers.

By the end of the project, Brave Tern had installed a total of 51 towers and nacelles and 10 rotor stars and Bold Tern had installed 24 towers and nacelles and 12 rotor stars.

Alstom Haliade™ Demonstrator

Posted on November 16, 2013

In 2013, Fred. Olsen Windcarrier’s Bold Tern installed the Alstom Haliade™ 6MW demonstrator turbine at the Belwind site. At the time it was the world’s largest offshore wind turbine ever to be installed in sea waters.

  • The Bold Tern was the first vessel to install an offshore turbine of this scale.
  • This was the sixth project for the Fred. Olsen Windcarrier jack-up vessels in their inaugural year.
  • The large deck space and robust and versatile crane were perfect for the Haliade’s™ exceptional dimensions.

Fred. Olsen Windcarrier’s scope of work was to deliver the fully mobilised Bold Tern along with engineering services, lift supervision and WTG technicians supplied by Fred. Olsen related company Global Wind Service.

Bard Offshore I

Posted on July 31, 2013

In 2013, Fred. Olsen Windcarrier’s Brave Tern installed the final 14 complete BARD 5MW wind turbines and an additional 2 rotor stars on the Bard Offshore 1 wind farm in the German North Sea.

  • This was the first project for Fred. Olsen Windcarrier that involved 5MW turbines.
  • This was the first time Fred. Olsen Windcarrier had handled and installed direct drive machines.
  • This was the first time for either of the jack-up vessels to use the rotor star deck layout.
  • This was the first project for Fred. Olsen Windcarrier to provide a jack-up vessel alongside a Bayard CTV.

The full scope of work supplied by Fred. Olsen Windcarrier and related companies included transport and installation of WTGs, marine engineering, and crew transfer vessels.

Borkum Riffgat

Posted on July 18, 2013

In 2013, Fred. Olsen Windcarrier installed 30 complete turbines at the Borkum Riffgat site in the German North Sea.

  • Bold Tern was the first vessel in the world to deliver and install eight Siemens SWT 3.6 120 turbines at a wind farm site in a single deployment.
  • The fastest complete wind turbine was installed in 10 hours.
  • The fastest turnaround time was in 16 hours.

Fred. Olsen Windcarrier also provided two of their specialist Bayard class service vessels within the scope of the contract, as well as technical manpower provided by Fred. Olsen related company Global Wind Service.
