Electrical penetrators for man-rated sub- sea systems are rugged connector systems that transmit power and communication signals through a vehicle's pressure boundary, decrease electrical complexity and reduce dependence on operator skill. They are tailored for rigorous conditions and have a variety of advantages for subsea applications, including low maintenance and potential long-term use. Requirements BIRNS developed three sets of National Pipe Thread (NPT) penetrators for each system, certified to the American Bureau of Shipping (ABS) product design assessment. One set had nine BIRNS P25N-1 6-RA-LS units, where P25N indicates a 1-inch NPT shell size, 16 is the number of No. 16 American wire gauge (AWG) electrical conductors, RA means right angle and LS stands for low-smoke zero-halogen (LSZH) cables. Once it was determined that the penetrator inserts were impervious to the ingress of helium, BIRNS technicians electrically terminated cable conductors to the outboard side and LSZH cables to the inboard side.

BIRNS designed the connectors to withstand high open face pressure to six kilometers and to meet other demands of Oceaneering's ROV system, which required elevated contact density to ensure the accuracy of the sonar readings. While Oceaneering's sonar system had legacy MIL-C-2421 7 connectors built into the instrument base, the amount of gold on the BIRNS flange connector contacts was 2.5 times more than is required to fulfill US Military Standard MIL-G-45204, which only specifies gold plating as thin as 20 microns. With relatively high pin counts in both of the connector designs, the alignment of pins to existing mating sockets needed to be precise. The tooling designs, fabrications and keying methodology had to be carefully created. Engineers developed precision mold tooling sets for the 3P-1 7-FR-CUSTOM and 3M-9-FR-CUSTOM that fit pinned together to prevent lateral or rotational movement, keeping the molds aligned and preventing discrepancies that might result in possible inaccuracies in contact alignment.

BIRNS Inc. was recently called upon to deliver a custom hybrid electro-optical connector and cable assembly for the Naval Facilities Engineering Command/Engineering Service Center (NAVFAC ESC) at Naval Base Ventura County in Port Hueneme, California. The BIRNS Millennium hybrid electro-optical connectors were created specifically to push the technological barriers inherent in transmitting significant amounts of real-time data for sub- sea observatories, towed data acquisition devices, remotely operated vehicle projects or any use of underwater electro-optical systems. In order to deploy the system from a small craft, NAVFAC ESC requested that BIRNS design a connector system that could achieve multiple operational requirements. The BIRNS MillenniumTM series was developed to deliver all requisite high-performance attributes in one low-profile system. The system consists of an electrooptical cable assembly (3T-H02012-CP) with a mating flange receptacle (3T-H0201 2-FR). The assembly has two multimode optical fibers, eight 2.5-kilovolt conductors and four 600-volt conductors.

BIRNS, Inc. is an ISO 9001:2008-certified global leader in the design and manufacturing of high-performance lights, connectors and custom cable assemblies. All of BIRNS's technologically advanced products are relied upon to perform under pressure - whether they contribute to the success of thousands of hours of project research, priceless technical equipment or an underwater vehicle with personnel aboard. BIRNS began developing penetrators in 1999, and quickly developed industry-leading engineering and testing procedures which resulted in the company receiving coveted ABS Product Design Assessment (PDA) certification for all electrical penetrators and cable assemblies for underwater vehicles, systems and hyperbaric facilities. Now, like all BIRNS penetrators, the BIRNS P38-100-24-RA-LS for AC Plus is tested per BIRNS's ABSapproved test procedure ETP-6510-101 (electrical penetrators - submersible and non-submersible PVHO). The inboard sides are subjected to 1000psi of helium during the test. Any sign of leakage would result in immediate rejection if evidenced.
