The uncrewed vessels about to transform sea rescue

Navigating icy waters with ease – Saab's uncrewed Docksta LHSRV, a beacon of hope in maritime search and rescue

The vastness of the world's oceans poses significant challenges for search and rescue operations, especially in remote areas far from shore. However, a groundbreaking initiative by Saab's Docksta Shipyard is set to revolutionise maritime rescue efforts. Let's delve into the innovative concept of the Docksta Loitering Optionally Crewed High Speed Rescue Vessel (LHSRV) and how it could be a game-changer for search and rescue missions, particularly in challenging environments like Canada's Arctic region.

Saab's Docksta Shipyard is developing a new generation of rescue craft that uses remote-operation technology to drastically reduce response times for maritime accidents. The Docksta LHSRV is designed to be operated remotely, allowing it to remain at sea for extended periods, poised to respond quickly to emergencies. This innovative approach could potentially transform the landscape of maritime search and rescue.

Key features and capabilities

  • The LHSRV could achieve speeds exceeding 40 knots, providing a rapid response to emergencies.
  • Cutting-edge autonomous and remote-operation technologies, demonstrated in Saab's Enforcer III test craft, would enable full control from a land-based control room, allowing the vessel to navigate high seas without crew limitations.
  • The vessel's 20-meter hull, based on Saab's successful Docksta 20 Interceptor craft, is constructed from aluminium for durability.
  • A self-righting design facilitates quick recovery from capsizes and survival in rough seas.
  • The superstructure is designed to minimize ice build-up, making it suitable for operation in cold water environments such as the North Atlantic.
  • A substantial battery system, rechargeable by a generator and photovoltaic cells, allows the craft to remain on station for 5 to 20 weeks, depending on conditions.
  • The vessel's range for rescue missions extends up to 300 nautical miles on top of loitering time, enabling it to cover vast areas effectively.
  • The LHSRV could serve as a communication hub at the scene of an accident, facilitating interaction with stricken vessels.
  • A remotely operated man-overboard system allows the retrieval of survivors in the water and evacuees from sinking vessels.
  • The boat’s interior includes life-support compartments to ensure the safety of evacuees in high seas.

With the concept unveiled, the next crucial step in this groundbreaking initiative is the construction of a prototype. The development of the Docksta LHSRV marks a significant leap forward in the quest for more efficient and responsive maritime search and rescue operations, showcasing the commitment of European companies like Saab to pushing the boundaries of technology for the greater good. As we eagerly anticipate the next phase, it's clear that the future of maritime rescue is taking an exciting and unprecedented turn.
