Wind & offshore

przemysław rduch

Offshore Wind Farms never stops. Since 2009 5 MW turbines the fleet must be ready to install 15 MW + by 2025. This requires proven design and an innovate solutions in next generation fleet. BoDo constructor project required a very through research and several iteration already at the early stage. Elements of jack up, mooring ans anchoring systems have been combined to create a unique system for moving objects. Wind Farm Installation Vessels has become a challenge for engineers. Right design optimisation makes the vessels capable to transport and install heavy equipment in various weather condition. Similarly a transport fleet is a key factor for entire process of Wind Farm installation. Combination of semi-submersible heavy lift vessel equipped with a crane gives to the vessel a great flexibility.
