Two Moray Base versions

Moray Base 1.0

The Moray Base 1.0 is a most cost effective floater (both Capex and Opex), with excellent motion characteristics and capable of supporting 15 MW turbines and above in harsh environments. The AiP awarded design focuses on an industrialized fabrication process combined with minimum maintenance requirements.

Moray Base 2.0

Based on producer feedback, we have developed a unit that is even easier to produce and to transport. While maintaining the production philosophy, the Moray 2.0 replaces the segmented elbows of the Moray 1.0 by even easier producible elbow connections. The patented construction consisting of penetrating horizontal tubes in vertical columns provides for similar superior strength and fatigue behaviour as segmented elbows.

Maridea designed two Moray Base versions

  • The “Active” configuration is compact and has a ballast system to compensate for rotor rust.
  • The larger “Passive” configuration, without ballast system is even more maintenance friendly.

The 15 MW Moray Base is designed for harsh world-wide conditions. The shown 9.5 MW design is projected in a more moderate environment.

Foundation concept is generic

  • Scale/sizing to be optimized for turbine
  • Scantlings to be optimized for farm site

Support of 15MW turbine is possible with 12m tube diameter which is suitable for existing production facilities.
