Lowestoft pontoons


ABP required a new floating CTV facility at Lowestoft to service wind farms in the southern area of the North Sea. RWC were engaged by Marine Design Limited to undertake the sizing and topside design for their Dockmaster concrete/polystyrene modular pontoon system and a design for the pontoon to shore guidance/anchoring system.


RWC developed a restraint system comprising struts and braces fixed to shore-based anchor blocks to resist berthing and mooring forces and hinged in the horizontal plan to manage tidal variations and wave disturbances. The system limited the need for expensive guide piles in the dock. The pontoons were constructed in Marine Designs facility in Cornwall.


The berth was designed and completed in under 12 months providing a functional and economic facility for CTV’s operating in the North Sea.
