The advantage of buoyant designs is that they can be floated into place, removing the need for cranes, barges, jack-ups or divers that are impractical in strongly tidal flows such as the Pentland Firth. For Triton installation to an existing seabed anchorage, all that is required is an A-frame workboat or multi-cat with moderate DP capability and a tug to provide stern stabilisation.

10MW Towout

For transportation, the tether arm of the Triton platform is stowed between the de-ballasted main spar buoys so that Triton can be towed into position with minimum draft and the turbines clear of the water


On arrival at site the tether arm is lowered and the 3 DoF connection system attached to its lower end is engaged on a pre-installed seabed spigot (see Anchorage).  All moving or wearing parts associated with the connection system  are thus retrievable to the surface.

Once fully connected the Triton can be ballasted and put into the operational position

With the turbines in operation, the spar buoys always stay clear of the seabed, held up partly by buoyancy and partly by lift on the hydrodynamically-shaped crossarms.


Transition from the surface floating to the operating position is achieved by use of water ballasting.  Ballasting and de-ballasting transitions take about 30 minutes and can be triggered remotely so that the maintenance crew arrives as the platform arrives in its access position.
