Even though she is named Kirkwall 700 , this sea going crane is a rare visitor to Kirkwall.
Lately she has been employed at the “Falls of Warness” moving 200 ton blocks of concrete for the Marine renewable’ s activity there.
That is done with the green hydraulic ” grab” seen in the pic.
She is normally towed into position by the “Green Isle” as she has no independent motive power. With the strong currents there , up to 9 Knots un-mooring demands a high degree of professionalism from all concerned.
The Kirkwall as her name implies can lift 700 tons.
