Large Modular Jacket LMJ

New jacket substructure concept for installation of large turbines at depths between 50 and 100 metres

This new substructure will reduce the current cost of energy at depths greater than 50 metres and increase production capacity in ports

The main objectives of the wind energy sector in recent years have been focused on reducing energy production costs and the search for a greater wind resource to increase energy production.

However, despite the fact that moving wind farms further away from the coast allows for a greater wind resource and higher quality, and despite the fact that most of the locations in Europe near the coast and at shallow depths are already occupied, there is currently a technological limitation that is holding back the exploitation of marine areas further away from the coast and at greater depths. On the one hand, bottom-anchored solutions at depths greater than 50-60m present limitations due to assembly in port and due to the high costs and low availability of the necessary installation means. On the other hand, floating platforms currently have high manufacturing costs (which will be greatly accentuated with the increase in turbine size) and a still high technological risk, in addition to the fact that there are currently significant limitations on the number of units to be installed annually due to the production capacity of the ports.

In response to the above, within this project INGECID is working on the development of a new concept of jacket-type substructure for depths of up to 100m and turbines of up to 15MW that will reduce the current LCOE of the existing solutions for these depth ranges, making the installation of fixed substructures for these depths viable, and allowing an increase in the productive capacity of the ports.

The achievement of the above is based on the modularisation of the structure and an innovative installation process that will address the lack of availability and high costs of the installation means required for this new target depth range.

INGECID has been working for two years on this new type of jacket substructure, having applied for a patent for the protection of the main innovations associated with it.
