Triton Submarines


Full Ocean Depth

The world’s first manned submersible commercially certified for repeatable exploration to the deepest point in the ocean.

The Opportunity

Over 4,000 people have reached the summit of Everest, 220 astronauts have visited the International Space Station, twelve humans have walked on the moon…

The Triton 36000/2 Hadal Exploration System offers you access to the deepest point of the ocean, a place only three people have previously ventured.

Incorporating the world’s deepest diving independently certified submersible, the Triton 36000/2, and the support vessel, DSSV Pressure Drop, the System is currently on an around-the-world journey to dive to the deepest point in each of the world’s five oceans, as well as select historical wrecks.

Designed and certified to make thousands of dives to Hadal depths, during decades of service, Triton is excited to offer the opportunity for a private individual, government or philanthropic organization or research institute to acquire this remarkable System and continue the adventure.

Available to purchase today for $48.7 million, the Triton 36,000/2 Hadal Exploration System will be ready for delivery in 2019, after its successful expedition. The System will be fully proven. It will have extended the boundaries of human endeavor and technology. And it will offer a unique deep-diving capability unmatched by any nation or organization in the world.

Going Further…

Three years ago, an American client came to us with a dream. He had climbed the seven summits, the tallest peaks on each of the seven continents, and next he wanted to dive to the deepest point in each of the five oceans.

The challenge was set. Only two manned submersibles have ever dived to full ocean depth, and each made only a single dive. Could Triton design and build a submersible capable of repeat dives to the most remote, hostile and unexplored region of our planet? The answer, a resounding “yes.”

Following six-months of design concepts work, and a further six-months of design and engineering feasibility studies, a manufacturing contract was signed in the summer of 2016.

Over 150 suppliers from 36 different countries contributed to the project; in many cases re-thinking the technologies used to develop weight-critical and precision components in compliance with stringent quality requirements.

The titanium pressure hull required development of new advanced forging techniques to ensure the perfect circularity necessary for structural performance and an entirely weld-free construction. Measuring 3.54” (90mm) thick, it was tested at the Krylov State Research Center in St. Petersburg, Russia, to 140MPa (43,300ft or 13,200m) which is more than 20% greater than the deepest point in the ocean.

In summer 2018, the Triton 36000/2 successful completed a series of advanced sea trials in the Bahamas. The Hadal Exploration System, together with its interim class certification from DNV-GL, was handed over to its owner to commence its epic adventure.

The Five Deeps Expedition

The Five Deeps Expedition is now underway. A record-breaking exploration of the deepest points in the ocean.

Diving in many of the world’s most remote environments, including the Puerto Rican Trench, the Meteor Deep in the Southern Ocean and the Molloy Deep off Greenland, the Expedition Team will set new records and observe new species.

Additional dives to historic wrecks will be conducted, and the expedition will culminate in a dive to the deepest point – Challenger Deep in the Marianas Trench – which will be the ultimate validation of the Triton 36000/2 submersible, and will prove its capability, reliability and safety.


The Triton 36,000/2 FOD

“Limiting Factor”

A masterpiece of design, technology and precision engineering, the Triton 36000/2 is a two-person manned submersible capable of diving to the deepest and least accessible region of the world’s oceans, where the temperature rests a little above freezing and the external pressure over 16,000 psi (1,100 bar).

The titanium pressure hull required development of new advanced forging techniques to ensure the perfect circularity necessary for structural performance and an entirely weld-free construction. Measuring 3.54” (90mm) thick and with an inner diameter of 59″ (1500mm),  it was tested to withstand pressure >20% greater than full ocean depth at the Krylov State Research Center in St. Petersburg, Russia.

Designed to slip vertically through the water column, the Triton 36000/2 can reach the deepest point in the ocean in less than two and a half hours. Weighing just 11.2 tons, the submersible is far lighter than previous deep diving vehicles, an important consideration during launch and recovery. An array of 10 powerful electric thrusters provide for motion in all directions. Energy is provided from a pioneering set of full ocean depth certified Li-Fe-P batteries supplying 65 KWh of power.

The interior configuration of the Triton 36000/2 is unlike any previous deep-diving submersible. The ergonomically designed leather seats provide two occupants with the comfort and durability required for 12-hour dive missions. Four situational awareness cameras and three conical acrylic viewports ensure the pilot has an excellent view of the subsea environment. Ten, 20000 lumen LED lights, illuminate the ocean floor for the broadcast-quality 8k cameras.

The submersible has been designed with simplicity as the primary objective. Multiple, fail-safe systems provide additional peace of mind, while certification from DNV-GL provides the reassurance of third-party design and engineering accreditation for the first time ever in a full ocean depth manned submersible.

DSSV Pressure Drop

DSSV Pressure Drop is a recently refitted 224’ (68 m) deep submersible support vessel of 2,000 gross tons with accommodation for 47 passengers and crew.

As a former U.S. Navy’s submarine listening platform, and then a NOAA science and survey vessel, the highly efficient diesel electric propulsion system, extensive use of noise reduction shock mounting and ice-class hull, make her the perfect platform for exploration of the Earth’s most remote regions.

The vessel is equipped with a stern mounted A-Frame, providing a safe, effective and consistent method of launching and recovering the submersible in a wide variety of ocean conditions. On deck, a retractable climate-controlled hangar protects the submersible and support equipment.

On the main deck, wet- and dry-labs offer dedicated space for science activities, complete with blast freezers to preserve rare specimens and samples. Missions are controlled from the operations communications and command room, while the onboard media suite ensures everything is recorded, documented and edited for future broadcast.

DSSV Pressure Drop is Kongsberg-Simrad’s first installation of their new upgrade to the EM-124 multi-beam sonar, enabling precise and quick topographic mapping of the ocean floor at extreme depths, this allowing development of the perfect dive plan for the submersible in any location.

Exploration & Science

The ocean comprises 70% of the Earth’s surface, and over 97% of the sea floor remains unexplored. The deepest parts of our ocean have been out of reach of mankind, but with the Triton 36000/2, no subsea feature is beyond our reach.

From the towering mountain ranges of the mid-Atlantic Ridge to the plunging deeps of tectonic trenches; from historic shipwrecks such as the USS Indianapolis to hydrothermal vents; Earth’s final frontier and the last great adventure is now within our grasp.

For the first time in human history, Triton’s Hadal Exploration System will allow scientists unprecedented access to the secrets of the deepest ocean. Geochemistry, physical and chemical oceanography, geomorphology, igneous, metamorphic and sedimentary petrology, marine biology – all the hydrologic sciences will benefit immensely from the opportunity this unique System can accomplish.

The Landers

Triton’s Hadal Exploration System includes three FOD-capable Landers that will support the submersible and undertake pioneering science tasks.

The Landers feature L3 Systems-supplied acoustic modems that assist with the accurate navigation of the Triton 36000/2 submersible to the sea floor, and facilitate direct communications between the scientists aboard the DSSV Pressure Drop and the Landers.

Two Landers are equipped for a rack of six “push core” samplers for sedimentology, geology, and fauna collection, while autonomous science gear includes a conductivity, temperature and depth sensor (CTD) to record the conditions in the water column during descent and ascent, when near the bottom, and when on the sea floor.

Each Lander has a time-lapse camera system to record the presence and behavior of any mobile creatures, and two sets of baited traps to recover samples. The Landers will also collect 10 liters of bottom water for deep microbial work, which complements the sediment samples from the push cores.

The Value Proposition

The price of the Hadal Exploration System, comprising the Triton 36,000/2 submersible and its 224’ (68m) support ship, DSSV Pressure Drop, is $48.7 million.

The proven, certified System will be available for delivery in 2019, after a successful around-the-world expedition which includes over 50 record-breaking dives to the deepest points on the planet.

This capability matched by no nation on Earth, and it can be individually owned and operated. This is a one-off opportunity to acquire a remarkable System and represents incredible value considering the cost of previous, less capable, deep submersibles and their support ships.
