Deme Orion

De Orion van Deme is een superlatief vessel. Met een lengte van 216 meter, max payload van 30000 ton en een kraan die 5000 ton capaciteit heeft en daar nog het verleggen van kabels bij facliteert terwijl het geheel aangedreven wordt door LNG.

Kort gezegd een schip van deze tijd en voor deze tijd maar ook de toekomst. De specificaties zijn indrukwekkend.

Orion design and features

Orion has a length of 216.5m and breadth of 49m. It is designed with a large free deck area of 8,000m² and maximised deadweight to handle the heaviest jackets, monopiles and wind farm equipment.

An eight-point mooring system keeps the vessel steady during operations. The vessel has a maximum operating draft of 11m and maximum payload capacity of 30,000t.

It can accommodate 160 persons, with provisions to increase the accommodation capacity to 239 persons.

Orion also features two additional 100t auxiliary cranes, a helideck and 19.6m x 10.5m moon pools.

Installation equipment Orion is equipped with the heavy-lift crane (HLC) 295000, assembled on an 800t pedestal. The HLC boom has a length of 160m, and the whole crane has a height of 90m. The crane is capable of lifting loads of up to 5,000t to a height of 178m with an outreach of more than 30m. The lifting systems also include an auxiliary crane with a 1,500t capacity.

The vessel is equipped with an integrated motion compensated pile gripper (MCPG) to enable the installation of monopiles without the need for mooring anchors. In combination with the vessel’s dynamic positioning (DP3) capability, the MCPG keeps monopiles vertical and stable during installation.

The gripper is integrated with noise mitigation systems to reduce underwater noise associated with hammering.
