Scaldis: lifting at a higherlevel

RENEWABLES


2/20

From the early offshore renewable days Scaldis has been a key player in the rapidly growing

sector of renewable energy. Whilst Scaldis served in various disciplines of this market, the

majority of the works concentrated around the installation of jackets and substations.

Introduction


Scaldis executes its offshore activities with two heavy lift vessels, the

Rambiz (lifting capacity 3,300 tonnes) and Norma (400 tonnes). A third

heavy lift vessel is presently under construction (lifting capacity 4,000

tonnes) and will be available as from Q2 2014.

Our activities include: Transport and installation of concrete foundations/structures, jackets

and transformer units,

ROV surveys, piling, levelling, grouting and welding,

Transportation and installation of metmasts and

wind turbine generators,

Transportation and installation of current turbines.

Step 5- Jacket is above pre-installed piles by Rambiz.

- Assistance by survey equipment and ROV monitoring during

installation.

Step 7- Jacket is lowered further by Rambiz cranes.

- ROV monitoring.

Step 6- The leg with the longeststabbing point is now positioned into the pile

and lowered, monitoring by ROV.

- The jacket is lowered by the Rambiz cranes until the second stabbing

point is into its pile.

- When the two stabbing points are in position, the jacket will be

further lowered.

Step 8- Jacket is lowered until contact has been made between the jacket

shim plates and the piles.

- Rigging is disconnected.

- Grout operations can commence.
