OceanGate

A commercial submarine operator is teaming up with the University of Washington to build a new manned deep-sea sub. The five-passenger mini-sub could be available for charter by oil companies or researchers beginning in 2016.

Seattle-based OceanGate Inc. currently operates two small submarines for hire. It sees a market for deeper diving manned submersibles. To that end, the small company has partnered with the University of Washington and Boeing to design a stubby, bullet-shaped mini-sub with a 180-degree viewing dome in its nose.
