BIRNS, Inc.

BIRNS, Inc. designs and manufactures high-performance underwater and subsea interconnect products, lighting systems and related assemblies for demanding environments. Its core business centres on underwater connectors, subsea cable assemblies, subsea penetrators, and custom interconnect solutions that support power, signal, data, optical, RF and hybrid transmission. Those products serve deep ocean and marine applications, military programs, underwater vehicles, submarines, submersibles, diving bells, decompression chambers, and other rigorous subsea uses. BIRNS offers cable stock and cable assemblies in multiple configurations, including straight and 90-degree options, as well as products built with titanium or stainless-steel connectors and solid or oil-filled cables. The lighting business runs broad, covering subsea lighting, underwater chamber and floodlighting, dive lights, underwater flood light systems, underwater 360-degree lights, helmet and camera lighting, security lights, marine lighting, commercial emergency lighting, and nuclear facility lighting. Those products go to commercial divers, scuba diving enthusiasts, divers working in harsh underwater environments, submarines, ROVs and nuclear facilities. BIRNS produces specialized nuclear lighting for applications such as underwater camera lights, reactor core fueling lights, fuel pool lights, and seismically qualified emergency and high-bay lights. A distinctive part of the business comes from its attention to custom engineering, precision manufacturing, rigorous testing and certification. Design, development, meticulous testing, hydrostatic and pressure qualification, and compliance with standards including AS9100:2016, NRC 10CFR50 and NAVSEA PRO-020 all feature in that work. The company builds its products as mission-critical and field-proven items, made for reliability, depth capability, low loss, high bandwidth, and resistance to harsh conditions such as pressure, shock, vibration, corrosion and thermal stress. BIRNS serves customers worldwide in marine, commercial diving, defense, oil and gas, security and nuclear markets, with solutions intended for both crewed and uncrewed subsea systems and for nuclear power facilities. The connector, cable and lighting lines meet in the same place: hardware that has to keep working under pressure, in salt water, and in facilities where a failure carries a heavy cost.
