Bureau Veritas: New Rules for Diving Systems

the scheme of certification of the diving sub-systems, such as diving bells, deck chambers, launch and recovery systems (LARS) and self-propelled hyperbaric lifeboats (SPHL), and also provides detailed requirements for the design and construction of pressure vessels for human occupancy (PVHO), life support systems, including breathing gas supply, distribution and temperature control, as well as communication systems.   The new rules are currently being applied in a high specification dynamically positioned (DP3) newbuild diving support vessel (DSV) with integrated diving systems offering both

or hazardous substances into the environment. Your job by its inherent nature is a dangerous one. Put the emphasis on safety in perspective. On diving safety, personnel safety is always the primary consideration. This involves ensuring safety is paramount in both the design of Divers Life Support Systems (DLSS) as well as diving operations themselves. We ensure safety is designed into, tested for and eventually certified in all of our DLSS. Tragically though, we lost four sailors in diving accidents in 2013. As a result, we conducted a strategic assessment of the safety of diving operations

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

Divex standard products include; Gasmizer, Gaspure and Helipure gas recovery systems and the Kinergetic range of environmental conditioning and life support systems.  Manufacture will be distributed around various Divex global facilities including Aberdeen and Glasgow, Scotland, South Africa and Australia. Joint Managing Director, Derek Clarke commented, “This is a very important win for us particularly given the standing of both Keppel

we achieved guarantees that we have solid foundation to work with as we continue assembly of the sub.”   Following delivery of the three main components at OceanGate’s engineering and operations facility in Everett, Wash., the team will install the electronics, navigation and life support systems. 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
