Exceeding the boundaries of what can be achieved is the mantra of U-Boat Worx. This involves on-going innovation enabling us to deliver even better and ever more capable manned underwater exploration vehicles.

The result is the C-Researcher 3. This research submarine can dive to even greater depths with increased efficiency and further improved viewing while carrying larger payloads. This craft meets the demands and needs of private explorers, research organisations, and other subsea professionals.

    Total Safety

    The technical and engineering advancements of the C-Researcher 3 makes it the absolute leader in its class. Dive in total peace of mind with the submersible built using U-Boat Worx’s proven core components.

  • Endless diving

    The latest evolution of the high-capacity, industry-proven pressure-tolerant Lithium-ion batteries power the C-Researcher 3 over unsurpassed distances. Powerful thrusters optimised for efficient manoeuvring and special ascent/descent weights yield the optimal bottom time.

    Carefree launch and recovery

    Carrying advanced engineering features like the Freeboard Extender, the MARLIN controller and the man-rated single lifting point widen the operational window for any type of application and any type of sea conditions. Transferring passengers from deck or from high seas uninterruptedly allows the C-Researcher 3 to keep exploring without delay.

Anatomy

Pressure-Tolerant Battery System

The Pressure-Tolerant Battery System houses the batteries and electronics in oil-field pressurized enclosures. The use of pressure-resistant components reduces the size and weight of the submersible, particularly useful on the deep-diving models.

Manipulator arm

External equipment comprising a selection of subsea robotic arms together with work platforms and collection baskets can be installed on most of the U-Boat Worx models.

Flexible Diving Tanks

Diving tanks provide buoyancy and stability on the surface. U-Boat Worx’s flexible diving tanks are made of rubber-like Hypalon®. When deflated to dive they completely compress, and do not replace their volume with water. This greatly increases underwater performance as there is no additional underwater mass, improving the streamline. Storing the submersible with deflated diving tanks also requires less space.

Single Lifting Point

The single lifting point makes launch and recovery quick and easy. By only having to attach at one point – to the crane – you create a safer environment. With the rapid-release and efficient-connect lifting gear, you can be quickly in and out of the water.

Thrusters

The powerful thrusters and the excellent manoeuvrability of the C-Explorer 3 boost superior surface performance. You will be able to go faster, manoeuvre better and expand your operational window.

Features
  • Pressure-Tolerant Battery System

    The Pressure-Tolerant Battery System houses the batteries and electronics in oil-field pressurized enclosures. The use of pressure-resistant components reduces the size and weight of the submersible, particularly useful on the deep-diving models.

  • Lithium-ion battery technology

    The latest in Lithium-ion battery technology is used to give our submersibles the ultimate performance, lowest weight, smallest footprint, and best endurance possible. The Lithium-ion battery can be quickly recharged and is maintenance-free.

  • Freeboard Extender

    Freeboard is the height between the hatch and the waterline. The Freeboard Extender is a sliding barrier that increases the distance between the water and the hatch opening. It simultaneously allows for the submarine to be operated in rough conditions and be stored in low-height garage spaces.

  • MANTA Controller

    The MANTA Controller allows for pinpoint precision manoeuvring. The intuitive controls allow for supervised passenger steering, offering passengers an even more exciting experience. The controller allows quick access to intelligent pilot assistance functions such as Auto-heading and Auto-depth.

  • MARLIN Controller

    Developed to make Launch & Recovery effortless and efficient, the MARLIN Controller is a wireless remote to navigate the submarine on the surface. Once the submarine is in the water the controller can be used to navigate it away from the support vessel without a pilot inside. It can also be used to bring the submarine into position above a dive site or for easy passenger transfer.

  • Auto-depth

    With Auto-depth engaged, the submersible will hold steady at its current depth. When applying vertical thrust, the function will automatically disengage and seamlessly respond to the pilot’s commands. This function is part of the Intelligent Pilot Assistance Features.

  • Auto-heading

    When Auto-heading is activated, the submersible will automatically hold its current heading, whether following a course or facing an object of interest. This function is part of the Intelligent Pilot Assistance Features.

  • UIS

    The U-Boat Worx Information System (UIS) gives the pilot direct access to all relevant information on a clear touch-screen display. This PLC-based sensory network ensures the right information is provided at the right time. The UIS makes diving effortless.

  • Vector Weights

    Time and battery power to reach your mission depth is greatly reduced thanks to the biodegradable Vector Weights. Once the desired depth is reached a Vector Weight can be released to regain the preferred buoyancy of the submersible. To accelerate the ascent, another Vector Weight may be released.

  • Single lifting point

    The single lifting point makes launch and recovery quick and easy. By only having to attach at one point – to the crane – you create a safer environment. With the rapid-release and efficient-connect lifting gear, you can be quickly in and out of the water.

Safety
  • Maximum depth protection

    The MDP feature prevents the pilot from diving deeper than the submarine’s maximum operating depth. In case the submersible should ever find itself too deep, this safety feature will automatically raise the sub until it is once again within its ideal depth limits.

  • Deadman's Switch

    This DMS safety system will automatically resurface the submersible in the unlikely event that the pilot becomes incapable of controlling the submarine. The pilot needs to acknowledge the DMS every 10 minutes, otherwise it will initiate the ascent procedure.

  • Drop Weight

    This weight can be manually released from within the submersible to increase the buoyancy of the submarine and return to the surface.

  • Safety Buoy

    The red buoy is characteristic for U-Boat Worx submersibles. When released it marks the position of the submarine on the surface. The Dyneema Rope attached measures 1.5 x the operating depth of the submersible, and is strong enough to lift it to the surface.

  • Pinger

    A Pinger gives out a pulse that can be received on the surface. With the receiver unit, you can pinpoint the exact position of the submarine when submerged.

  • DNV-GL Certification

    Certified by leading classification society, DNV-GL, requires each individual submersible to meet stringent and extensive rules and regulations, as well as pass a range of rigorous test and trials from design to final delivery. Overseen by independent surveyors, this is an independent verification of the safety of every U-Boat Worx submersible.
