This webinar has been postponed due to unforeseen technical circumstances - sorry for any inconvenience that this may have caused.

The ever-increasing size and quantities of offshore wind turbines installed means that a change is needed to optimise the shipping of project cargo between manufacturing and marshalling port facilities, and the feeding of wind turbine installation vessels offshore.

We have seen attempts made at unitisation, such as the wind industry grouping sets of three blades into a “unit”. The “Twistie” turbine cassette - a modular project cargo transport frame system - allows any turbine to be unitised and handled as a single piece of cargo.

A RoRo offshore vessel-to-vessel transfer of components avoids both: 

  • The wave limits experienced by floating feeder vessels
  • The wind limits associated with jack-up feeder vessels

Seafastening using the same layout as a deck full of cargo containers and optimised to facilitate self-propelled modular transport trailer usage; "Twisties" and the fast feeder vessel strategy would represent a step-change in the transportation and installation of logistics for the offshore wind industry and further afield.

Project objectives

Together with industry stakeholders, we aim to establish a Joint Industry Project (JIP) to develop a Recommended Practice document for the unitisation of project cargo using the "Twistie” turbine cassette which facilitates the adoption of a fast feeder vessel strategy.


This 45 minute webinar will demonstrate the “Twisties” concept and, expand and answer the following questions:

  • What are the current offshore wind cargo transportation and installation methods?
  • What are “Twisties” and how will they benefit developers, owners/operators, foundation & turbine manufacturers and others?
  • Next steps towards JIP realisation and beyond?
