US Navy Tests Flexible One-Atmosphere Diving Suit
diving bell, that is pressurized with gas so the pressure inside the bell matches outside pressure.The drawback is that, when returning to the surface, divers must ascend slowly and stop at intervals so they don’t suffer decompression sickness. This is a potentially lethal condition in which the inert gas dissolved in the blood and tissues by high pressure forms bubbles as pressure decreases.DSEND’s one-atmosphere environment presents a solution to this challenge. Equipped with a self-contained life support system, the DSEND suit encloses a diver in a stabilized pressure cocoon during the

Wärtsilä Gas Units Selected for Largest Ever Spar Platform
A new spar platform being built for Statoil's Aasta Hansteen field off the coast of Norway will feature Wärtsilä's Inert Gas and Nitrogen Generator systems, the power solutions company said. The contract has been issued in the first quarter 2014 by Hyundai Heavy Industries (HHI) of South Korea, the yard building the platform. The Wärtsilä Inert Gas Generator will utilize titanium in its construction, the first time ever that this material has been used in such a system. Titanium was preferred due to its superior corrosion resistance in relation to sea water. Wärtsilä's
Wärtsilä Inert Gas Unit for Statoil N. Sea Platform
The enormous new offshore spar platform being built for Statoil's Aasta Hansteen field off the coast of Norway will feature Wärtsilä's Inert Gas and Nitrogen Generator systems, which will utilise titanium in their construction, the first time ever that this material has been used in such a system. The contract was issued in the first quarter 2014 by Hyundai Heavy Industries (HHI) of South Korea, the yard building the platform. Wärtsilä's extensive experience and technical expertise in gas handling systems were critical factors in the award of this contract. The use of unconventi
South China Sea Saturation Dive Reaches 300m
saturation dive as 3 divers returned safe and sound from deep water to the living chamber on their ship, informs Xinhua. Saturation diving technology, a necessary part of deep sea salvage and rescue operations, enables divers to withstand high water pressure by saturating their tissue with inert gas. China is now developing saturation diving technology that would work at a depth of 500 meters under the sea reports Xinhua, citing Wang Zhenliang, director of the China Rescue and Salvage Center of the Ministry of Transport. To date, eight countries, including Britain, the United States, Switzerland
China Offshore Inert Gas Orders for Norway's WTS
Wilhelmsen Technical Solutions (WTS) say they have secured multiple orders to supply Maritime Protection Inert Gas Generator (IGG) systems for installation on vessels under construction for operations offshore China. The Maritime Protection systems will be installed on three FPSOs for oil major China National Offshore Oil Corporation (CNOOC). Two identical systems, comprising a deck house module with electric power, fuel and sea water supply/discharge, will be supplied for two FPSOs which will operate in the Bohai oil field in northern China. Both systems are designed for dual fuel operation and

In addition to this and other exhibits, Wärtsilä Ship Power experts will be on hand to discuss a variety of topics in the following areas: Environmental excellence and compliance – Ballast Water Management Systems (BWMS), exhaust gas cleaning,inert gas systems,waste water management, retrofitting Gas and fuel flexibility – Dual-Fuel Engines, including the game-changing 2-stroke low pressure dual-fuel engine technology, the market leading 4-stroke dual-fuel engines, and the Wärtsilä GasReformer Efficiency – latest
Tideland Warning Technology for Offshore Met Masts
back-up batteries and volt-free contacts for SCADA may also be included. SeaBeacon 2 System 6 is the racon most widely specified by name across the world due not only to its technical capability but also to the exceptional reliability and minimal maintenance requirements enhanced by the design's inert gas protection system. Standard features include side-lobe suppression, proportional scaling and normal traffic power consumption of only 0.75W, with a heavy traffic maximum of only 1.06W. The Tideland design also offers a high sensitivity of -50dBm in both X- and S-Band, meaning that the
