Antipodes Submersible

Utilized for deep-water expeditions, Antipodes is a manned submersible that enables commercial and scientific applications for researchers, scientists, filmmakers and content providers. Through this unique submersible, OceanGate clients can access underwater environments and target sites at depths of 305 meters (1,000 feet).

Antipodes accommodates a crew of five, including a pilot, and boasts a 305-meter depth rating, which allows access to much of the world’s continental shelves and the biology that exists in those areas. Twin 58-inch hemispherical acrylic domes also provide exceptional views for direct observation and filming during deep-sea expeditions, while its 6,350 kg (14,000 lbs) weight and 13.6 ft x 8.3 ft x 8.7 ft in dimensions ensure impressive portability on a variety of ships.

First built in 1973 as a diver lock-out sub by Perry Submarine, the PC-1501 spent several years operating in the North Sea oil fields. Rebuilt in 1995 and renamed XPC15, it was installed and operated around the world aboard the Mystere, a 200-foot yacht. It was further modified in 2001 and renamed Antipodes by Submarine Adventures, which successfully operated the sub in Milford Sound, New Zealand, where it took thousands of tourists on dives to depths of 1,000 feet.

Engineered with both safety and convenience in mind, Antipodes is certified by the American Bureau of Shipping (ABS) and has proven itself as a safe and effective vessel over the course of more than 1,300 dives in a variety of sea conditions. While typical mission profiles will call for dives of 2-8 hours in duration, Antipodes has the additional capability to provide life support for five people for 72 hours.
