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

The MoShip

Imtech Marine to Power Turkish Navy Vessels

Marine since 2010. The core of its activities consists of electrical and automation system integration, including complete onboard electrical installations. Elkon has a renowned reputation and excellent relationships with the Turkish Navy and Shipyards.   The MoShip will be capable of providing the lifesaving support to a disabled submarine and evacuating the crew. The RatShip will be capable of towing ships as well as firefighting. Both ships will be equipped with modern rescue systems and equipment such as remotely operated underwater vehicle (ROV), atmospheric diving suit (ADS), submarine ventilation

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

wound carbon fiber main cylinder that forms the center section of the submersible’s pressure hull.   Following assembly of the three main components, the pressure hull will be independently tested to ensure vessel integrity before the final installation of electronics, navigation and life support systems. Most of these systems to be used on Cyclops 2 are currently in use on Cyclops 1, OceanGate’s submersible that can dive to depths of 500 meters. The first in-water dives for Cyclops 2 are planned for late 2017

6600/2’s passenger compartment remains at surface pressure irrespective of diving depth and is engineered utilizing a new technique developed by the manufacturer’s acrylic manufacturing partners.   Furthermore, the Triton 6600/2’s maximum dive duration is 10 hours, though its life support system will operate for up to 96 hours.   “It should take about an hour for the sub to get down to its maximum depth, but once there, the pilot and passenger will have plenty of time to investigate a wreck or some other artifact on the bottom, and shoot video if desired,&rdquo

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

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

and minimize the need for custom-engineering.   It focuses on rapid application configuration techniques based on common standardised building blocks and integration techniques. By creating effective and easily integrated building blocks, the system can be used from initial installation through life of field integrity support and eventual decommissioning.   Their newly launched system covers suction piled structures, mono-piles, wind turbine and jacket installation and flowline spool orientation measurement  as well as providing short and long term fatigue monitoring capabilities

It is a useful tool to assess the efficiency of anti-roll tanks, sloshing in liquefied natural gas (LNG) tanks, safety of cruise ship swimming pools or drop tests with a free-fall lifeboat from a moving platform.   As the positioning system of the hexapod is very accurate, another useful application is the validation of measurement equipment. Recently, MARIN used it to evaluate the measurement accuracy of a Datawell wave buoy for Shell and Woodside. Wave buoys are occasionally
