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.

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.

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.

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.

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.

Acrylic Viewport

The fully acrylic hyper-hemispherical viewport gives you the best panoramic view of the underwater world possible.

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.

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.

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.

Omni-directional operation

Apart from the basic forward, reverse, up and down movements, the submersible can also move laterally. Lateral movement greatly optimises object approach, view, and dive efficiency.

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.

  • Maximum depth protection
  • Deadman's Switch
  • Drop Weight
  • Safety Buoy
  • Pinger
  • DNV GL Certification

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.
