DOER Marine

Deepsearch – a manned full ocean depth submersible

Over the past 50 years, advances in engineering have fundamentally changed the way we live our lives. Yet it has been almost 50 years since the only manned expedition to the deepest part of the ocean.   In that span, the design strategies for deep ocean exploration have not changed.

Discover the Ocean with Google Earth

Google Earth lets you fly anywhere on Earth to view satellite imagery, maps, terrain, 3D buildings, from galaxies in outer space to the canyons of the ocean. You can explore rich geographical content, save your toured places, and share with others. Read more


DOER provides innovative solutions for inspection of these vital and sometimes aging structure with linear penetrations of 11.25 KM/7 miles, real time image/data fiber optic transmission, robotic intervention, and manned systems for extreme penetrations.

Surveillance & Detection

DOER Ocean Explorer X2 is deployed for scientific survey in Cordell Banks/Gulf of the Farallones National Marine Sanctuary.  This all electric system is rated to 1000m

Search & Recovery

DOER has responded to search and recovery efforts involving military and civilian aircraft, sunken vessels, towed arrays, and drowning victims, both in open water, through ice, and confined space conditions.  Custom tools and recovery packs have been developed to facilitate cutting and rigging from both remotely operated vehicles and manned submersible.


DOER has trained more than 100 scientists to operate human occupied submersibles.  Many others have benefited from our ROV and HOV training on both DOER and third party equipment.

Systems Integrations

Customers trust DOER with even the most complex system integrations. Read more…
