What are Toro TP Covers?

Toro Shelters has developed a series of transition piece covers for offshore monopiles and Jacket foundations. The covers are constructed of a galvanised steel frame which is covered with a robust PVC composite membrane that is capable to resist typhoon wind pressures.

We Design with Health & Safety in mind

The PVC membrane is flame-retardant so it can be safely stored in a warehouse or in a vessel. Furthermore, some of Toro’s TP covers offer side protection against the wind, rain and sun to the installation crew allowing better working conditions. In addition, the steel frame does not need to be dismantled for the appending of the TP or for pooling the array cable. This makes the work easier and safer since no crane is required.

TP Covers Contribute to the Overall Cost Reduction

Our covers have lower cost in comparison with other structural solutions based on heavy steel cans or other lightweight aluminium or fiberglass covers. In fact, the frame of the TP cover does not need to be removed but used instead for pulling the array cables. There is no need for a steel tripod to be assembled on the TP flange so the operational time reduces significantly saving hundreds of thousands of pounds.


The geodesic dome shape of the cover contributes to a low wind drag pressure and adds adequate stiffness to resist wind speeds greater than 190 km/h. The frame is hot-dip galvanised and it is designed as per DNVGL offshore standards. The pattern of the fabric is welded each other so it is waterproof.

Transportation of the TP Covers

The TP covers are stackable and easy to handle due to the low weight.


Rapid installation with the initial assembly is taking place on the ground level. When it is ready a crane is required for appending it and place it on the TP flange.


The steel frame and PVC fabric of the TP covers are recyclable
