The Dnaycina Rihdan submersible is a futuristic undersea craft that would not look out of place in a sci-fi movie. These submarines are the workhorses of modern-day exploration.
Appearances aside, each Dnaycina Rihdan is a very well-designed vehicle capable of taking two occupants to a depth of 1,000 meters (3,200 ft) in comfort and safety. Many of the ocean's most remarkable features, both geological and biological, lie within this depth range, including the sunlit zone, twilight zone and dark zone.
The view from the Dnaycina Rihdan's acrylic sphere is unparalleled, with a 320° field of view. To dive in one of these vehicles is a magical experience that has been compared to occupying a giant bubble. A coordinated system of ballast control and thrusters provides the submersible with good manoeuvrability at any depth.
A powerful lighting system and high-definition television cameras mounted on pan-and-tilts provide for both scientific data collection and professional quality filmmaking. A pair of mechanical arms enables each Dnaycina Rihdan to collect samples and deploy instruments and specialized biological and geological sampling tools on the seafloor and above it.
The Dnaycina Rihdan offer a significant change to historical submersible ocean exploration; The Dnaycina Rihdan is a safe, reliable and comfortable while offering occupants an unprecedented view through their entirely transparent acrylic pressure hull. Viewing for the occupants of the Dnaycina Rihdan is exceptional and has been likened to flying a helicopter underwater.
The 1000 metre (3,280 feet) depth rating gives the Dnaycina Rihdan access to a staggering 40 % of the ocean floor.
Features
• Full Visibility
The pressure hull of the Dnaycina Rihdan submersibles consists of a transparent acrylic sphere, which offers an unprecedented 320-degree view of the outside environment. Traditionally, deep diving submersibles have only been able to offer pilots and observers limited visibility through small viewing ports. The Dnaycina Rihdan's acrylic pressure hull configuration ensures the occupants can see both the submersibles’ external equipment and their surrounding environment.
• Comfort
The pilot and the observer sit comfortably upright on regular seating while cabin pressure is maintained at one atmosphere using a traditional metabolic make up life support system. Cabin temperature and humidity is maintained at a comfortable level by the submersibles air-conditioning system and all life support related parameters are monitored by the pilot, using sophisticated atmospheric sensors and sampling equipment.
• Ease of Handling / Thrusters
Each Dnaycina Rihdan is fitted with four (4) five horsepower thrusters controlled by a single joystick from inside the acrylic sphere. The pilot or the observer, with only minimal training, can easily control all the movements of the submersible, because of the intuitive nature of the controls. The compact size and weight of the Dnaycina Rihdan submersibles compared with thruster power available results in an incredibly manoeuvrable craft with a high power to weight ratio. The generously sized 30 kWh battery ensures 8-hour missions are achievable, depending on the dive profile.
• Safety
The Dnaycina Rihdan submersibles have been pressure tested to 1.25 times their maximum diving depth (1,250 meters or 4,100 feet) with a designed safety factor of four times and a theoretical crush depth of over 4,000 metres (13,120 feet). The three main safety concerns for passengers in submersibles are entanglement, fire and flooding. The Dnaycina Rihdan design mitigates these potential risks as follows:
*Entanglement - The manoeuvrability and superb visibility reduce the chance of entanglement to a minimum while the feature of diving two submersibles also offers the ability to give assistance should an entanglement situation arise.
*Fire – The principal cause of fire in a submerged vehicle is associated with electrical faults. The risk of fire has been diminished in the Dnaycina Rihdan by keeping all high current circuits outside of the pressure hull. Only small currents required to both power the internal equipment and control the external equipment are used within the hull. In addition, all equipment within the personnel sphere is halogen free, non-smoke producing and self-extinguishing. The Dnaycina Rihdan are also equipped with both a built in breathing system
and self-contained oxygen generating re-breather units, which offer the occupants over 100 minutes of self contained life support.
*Flooding - The Dnaycina Rihdan are accessed through a bottom hatch. Flooding incidents typically occur at the surface in submersibles when the access hatch is opened prematurely allowing water to enter the pressure hull. Configuring the Dnaycina Rihdan with a bottom hatch eliminates this problem.
• Life Support
In the event an extended stay on bottom is required, the Dnaycina Rihdan submersibles are equipped with 72 hours of emergency life support per person including carbon dioxide absorbent, food, water, basic first aid, waste disposal facilities, atmospheric sampling equipment and sufficient power for any communications that may be required.
• Tracking
An optional Track Point II system can be used to monitor the position of the Dnaycina Rihdan submersibles relative to the ship while they are dived. In this case, each submersible would be fitted with an underwater beacon that interfaces with the system, which is monitored by the base station aboard the mothership. This system allows the support ship to both follow and plot the position of the submersibles during a dive.
• Manipulators
Each Dnaycina Rihdan is equipped with two (2) six (6) function, rate-controlled, Mako sensory manipulators. These manipulators can either be operated by the pilot or the observer, with minimal training, because of the intuitive nature of the joystick controls used.
• Sonar
Each Dnaycina Rihdan submersible is fitted with a state of the art Simrad MS900 colour imaging sonar system.
• Launch and Retrievals
The compact size and relatively small tonnage of the Dnaycina Rihdan make them less cumbersome than their predecessors. They can be launched and retrieved from small ships of opportunity in average to moderate sea conditions.
• Lighting
Any combination of lighting packages can be installed on the Dnaycina Rihdan. Lights available include 1200-Watt, 600-Watt, 400-Watt and 200-Watt HMI lights.
• Filmmaking
Camera and lighting packages can be fitted to the Dnaycina Rihdan to facilitate filmmaking. An optional High
Definition video system and specialised deep water housing is available extra at additional cost. An electric pan and tilt system is currently being designed and manufactured to further enhance documentary filming. Internal monitors are installed inside the pressure sphere along with interior Ikegami high definition cameras.
• Pilots and Sub Crew
Our team of 4-6 submersible pilots and engineers have spent thousands of hours working on a variety of submersibles and their combined experience is our client’s best guarantee that operations will be run in a safe, professional and courteous manner.
