Simplicity of Design

The hull is an optimized steel structure that is simple and easy to build. There are no mechanical systems operating when deployed, and it avoids fatigue concerns with the welded joints of tubular members found on semi-submersible platforms.

Motions and Accelerations at the Turbine

PelaStar has no pitch, roll, or heave, which minimizes the motion and accelerations at the nacelle that degrade performance and increase wear on bearings and other components.  This model testing video and the graph below illustrate the motions of PelaStar.

Reliable Installation Schedules

Efficient quayside assembly, turbine testing, and partial commissioning significantly reduces offshore work, costly weather delays, and expensive offshore equipment support.

Compact Footprint

The tendons, with their vertical orientation under the hull, present a compact footprint that is advantageous in full-field plants as it reduces the risk of underwater interferences.
