Antipodes is a deep sea manned submersible with proven experience and an excellent safety record. She is well equipped and operationally dive-ready, having completed her three year American Bureau of Shipping (ABS) Classification Survey in February, 2017 that included a complete disassembly and inspection, as well as certification deep dive.

With six individual 5HP electric thrusters, Antipodes is highly maneuverable at depth and extremely comfortable for pilot and up to four crew. She features two large 58” clear hemispheric acrylic domes on both bow and stern that provide a unique platform for excellent viewing and real time crew collaboration.

Operating as either a stand-alone platform or working in tandem with other technologies (ROV, AUV, Sat-Diver) and equipment, Antipodes can be quickly configured to meet specific client needs and efficiently perform a wide range of underwater tasks including:

  • Visual inspection and observation
  • Data collection and sampling
  • Sonar mapping
  • Film production

This modular approach to hardware configuration and crew composition means Antipodes is ideally suited to projects where requirements and conditions may vary between dives.

  • Deploys off of any ship of opportunity
  • Does not require a man-rated crane (minimum rated crane capacity: SWL 10 tons)
  • Can operate in sea state 3
  • Can be surfaced towed using built-in bridle and rigging
  • Fully autonomous: Does not need tether or tethering related equipment
  • Speed approximately 2.5 knots
