The 142 meter long S-Class vessels RollDock Sun, RollDock Sea and RollDock Sky were designed by our in-house engineering department. With three different loading modes – Float-In / Float-Out, Roll-On / Roll-Off and Lift-On / Lift-Off – they offer maximum flexibility and are able to tackle the most challenging transportation requirements.
The ramp/deck design in combination with the ballast tanks make it possible to match every quay height, with the stern ramp allowing Ro-Ro cargo up to 4,000 mt per unit. During Flo-Flo operations, the S-Class vessels can submerge to 12.5 meters creating a draft in hold of 6.6 meters. With a draught of 5.67 meters the vessels are suitable for shallow draft waters, and each deck crane has the ability to lift up to 350 mt, or 700 mt in tandem lifting.
The RollDock Sun, RollDock Sea and RollDock Sky have been operational since 2010, 2011 and 2016 respectively.

The 142 meter long S-Class vessels RollDock Sun, RollDock Sea and RollDock Sky were designed by our in-house engineering department.
The ST-Class is the second generation of our dock type semi-submersible multifunctional heavy lift transport vessels.
Combi Dock I
The Combi Dock I is part of the pool agreement between RollDock and SAL Heavy Lift, and offers the same loading possibilities as the RollDock vessels.
