SCROLL UP & DOWN TO SEE TUGDOCK IN ACTION
Tugdock is a technology which enables heavy marine structures to be built or assembled and loaded-out in ports with water depth or space restrictions.
Tugdock Units (TDUs) can be mobilised alongside the quayside or attached to the structures as additional draft-reducing buoyancy.
TDUs are air ballast controlled submersible units which are modular and entirely road transportable.
TDUs can loadout substructures in as little as 5m of water.
TDUs can reduce draft and manoeuvre heavy marine structures.
TDUs provide a large waterplane area and create greater stability at shallow draft.
TDUs can be used during the marshalling, construction and O&M phases.
