The ships in action

Precision fleet

Specially-selected ships will be used during the various construction phases of the Sandbank offshore wind farm project. Alongside the five most important installation ships, several ships will be put to use throughout the course of the building phase lasting at least one and a half years.

These include vessels for material and crew transport as well as vessels to assist installation work. When construction work is at its peak, crew transfer ships will be needed on a daily basis to transfer crew members from Esbjerg to the offshore construction site and around the wind farm. At peak times up to ten vessels are in action in the wind farm at the same time.

Pacific Orca

The Pacific Orca from the Danish shipping company Swire Blue Ocean will be used for the transport and installation of the 72 monopiles. It is the sister ship of the Pacific Osprey, which was used to install the wind turbines of the DanTysk wind farm.

These ships are the largest installation vessels of their kind worldwide. It has its own engine, which can generate speeds of up to 13 knots (24 km/h), and can transport up to four sets of monopiles and the sound damping system at one time. An improved level of stability means the Pacific Orca is capable of carrying out installation work even with 2.5-metre-high waves and high wind speeds.

MPI Adventure

This multi-function vessel with a length of just under 139 metres from the MPI shipping company will be used in the Sandbank project for installing the turbines. The dead weight of the installation vessel is 6,415 tonnes, to which a further 530 tonnes of turbines and towers can be added.

The MPI Adventure will be used for the installation and transport of the turbines.

Stemat Spirit

This ship, owned by the Dutch company VolkerWessels, is responsible for the inter-array cabling of the wind farm which will link up the 72 wind turbines and connect them to the offshore substation.

The Stemat Spirit will transport the cables from the UK to the construction site 90 kilometres off the island of Sylt and install cables on the sea bed. A number of other support vessels will also be in action.

Ndurance

This ship belongs to VBMS and is also intended for use in laying inter-array cabling within the wind farm. The cables will be laid on the sea bed by means of illuviation. This is a process requiring the use of several ships as well as a great deal of coordination and attention to detail.

The Ndurance will help with the laying of cables.

Stanislav Yudin

With a length of 183.2 metres and a displacement of 5,600 tonnes, the Stanislav Yudin is the largest ship that will be used in the construction of Sandbank. Fitted with state-of-the-art technology, this giant vessel will be deployed to install the offshore substation at sea.

Sverdrupson

The 40-metre long Sverdrupson was chartered for use as a guard vessel by Sandbank Offshore Wind GmbH in April 2015. The guard vessel is in service 24/7 and ensures the safety of personnel and materials at the Sandbank construction site. The vessel is specially equipped for this task and approved by the German Maritime and Hydrographic Agency (BSH).

Sandbank wind farm area

The Sandbank offshore wind farm project area is located 90 kilometres off the coast of Sylt in the German North Sea and is therefore not visible either from land or from the islands just off the coast.

The environment

Just as with any other infrastructure project, a responsible attitude towards the environment and the natural surroundings is a key aspect of offshore projects like the Sandbank project.

Technology and components

Once the wind farm is completed, 72 wind turbines spread out over an area of 60 square kilometres will be using their vast rotor blades to turn the powerful North Sea wind into green energy.
