Lutra Marine have developed precision dredging tools for use in environmentally sensitive ports, harbours and marinas. Lutra's patented technology allows for the safe removal of sediment and rock from any aquatic environment without causing a drop in the local water quality.

Conventional dredging methods produce plumes of silt and increase water turbidity which causes damage to sensitive marine environments and affect breeding areas for economically important fisheries such as oysters and sea bass. 

Sediment regularly fills up ports, harbours and marinas reducing the depth of water and preventing safe navigation and mooring. Routine dredging is vital to keep these sites open and commercially viable.

Lutra Marine offers its equipment for direct sale, along with equipment leasing packages. They also offer a full suite of dredging services for both small and large scale dredging projects.

Lutra Marine - providing precision dredging without affecting the local water quality.


  • Prototype successfully developed and tested in partnership with Plymouth University.
  • Pipeline of potential clients who have requested demonstrations.
  • International patents filed and approved.
