Wind speed measurements for offshore applications using both mast and LIDAR on a floating platform


Off-shore wind measurements using a mast fixed on the sea-bed is subject to significant cost and additionally not applicable in deep waters. Remote sensing devices as LIDAR have been used on floating structures to reveal the drawback of the fixed masts off-shore.


In cases of a need for long term measured wind data or compatibility with current industry standards a mast should be also used along with the LIDAR or SODAR. This is what the present approach offers.

Main body of abstract

A purpose designed floating platform which minimizes the movement induced by the waves has been built. The platform incorporates a wind mast and a LIDAR together with all related equipment. Using this approach long term wind measurements are possible according to current industry standards for both shallow and deep waters. The platform has been designed and a prototype has been built and evaluated showing promising results. The platform can be deployed anywhere as considerable care has been taken to minimize infrastructure needed. Towing of the platform can be easily done using standard vessels while anchoring can be achieved either by gravity anchors, Tension Legs or hybrid methods. Results show small movements of the structure within the limits imposed by the current standards while during severe weather some correlation is needed.


Off-shore wind measurements using both wind mast & Lidar according to existing industry standards are now possible for both shallow and deep waters close or far away from the coast at reasonable cost.

Learning objectives
Floating platforms, if properly designed, can host wind masts and Lidars so that industry standard wind measurements can be achieved in shallow or deep waters either close or far away from the shore at minor infrastructure needs.
