EX-BM001-30 Functional Description

The external lifting unit makes it possible for a davit crane to lift 3000 kg. which eliminates the need of having other, larger and more expensive cranes on the offshore wind farm.

When needed, the external lifting unit is simply brought from its stored position ashore to the offshore wind farm and mounted on the Seasight Davit crane increasing its OSWL from typically 990/1000 kg. up to 3000 kg.
