Navy Develops Prototype for Diver Life Support

Scientists at Naval Surface Warfare Center Panama City (NSWC PC) have developed a prototype for a new life support system for divers, the U.S. Navy announced.    According to the Navy, the goal of the new system is to accelerate the deployment of Navy divers, increase safety and also conserve helium, a valuable natural resource.   "This new, semi-closed system was conceived to drastically reduce helium requirements," said NSWC PC Principal Investigator Dr. John Camperman. "And where possible we also incorporated proven technology in the system in order to speed

JFD Debuts Bailout Rebreather System to Safeguard Divers Lives

Bailout Rebreathing Apparatus (COBRA) for commercial divers, as a direct response to the urgent need for significant improvements in safety in the saturation diving industry.   The system significantly extends the duration of the supply of emergency breathing gas, delivering 45 minutes of emergency life support at a depth of 120 meters.  A conventional open-circuit 300 bar twinset bailout system will deliver only seven minutes at that depth. The extended emergency breathing gas supply significantly improves the likelihood of a successful rescue in the event of an emergency.   COBRA is

Just as robotic rovers on Mars now keep a digital eye on the Red Planet, a suite of electronic tools will soon send photos, observations and high-definition video of an alien environment just off our shores. “The ocean is the ultimate life-support system for the entire planet,” said program lead John Delaney, a UW professor of oceanography who is chief scientist on all four legs of this summer’s cruise. “The Ocean Observatories Initiative, and especially the cabled portion in the Northeast Pacific, will fundamentally

the new ship will enable scientists to carry out research programs that address urgent societal issues such as the need to understand the impact of polar ice melt and its effect on climate, global ocean circulation, sea level and the functioning of the ecosystems that regulate the planet’s life support systems,” Fox said. Cammell Laird’s requirements for Rolls-Royce to meet when designing the vessel included: Polar Code 4 ice class, a high endurance factor, with the capacity to be self-sufficient in fuel and supplies on voyages up to 19,000 nautical miles, space for a total of 90

Most of these systems to be used on Cyclops 2are currently in use on Cyclops 1, OceanGate’s submersible that can dive to depths of 500 meters. The first in-water validation test dives for Cyclops 2 are planned for Fall 2017 with deep water dives to be conducted in early 2018 in preparation
