Better life safety at sea - Emergency Position-Indicating Radio Beacon
5/23/2014
A new EPIRB (Emergency Position-Indicating Radio Beacon) makes it easier to locate people in distress at sea. The beacon is developed and manufactured in Norway.
- The new distress radio beacon takes cross-bearings from multiple systems. Several vessels can participate in search and rescue, and locating survivors becomes a lot more probable, says section leader Knut Asle at Hansen Protection in Moss.
The company has developed the new emergency beacon that will initially be fitted into survival suits worn by workers on offshore oil installations. Over time, anyone who works in vulnerable conditions at sea, such as fishermen or people working on offshore wind turbines, can have the emergency locator fitted in their work wear.
- Previous tracking transmitters used by offshore oil workers have only transmitted signals on the 121.5 MHz (VHF) emergency wave band that only rescue helicopters and rescue boats could pick up. But now we have developed a radio beacon that combines signals on several different frequencies.
Multiple systems
The beacon is mounted in a bracket in the survival suit. The technology used is not new, but the combination is the first of its kind.
In addition to sending signals over the emergency frequency, it also utilizes AIS, which is an anti-collision system for shipping. The beacon also uses the American GPS satnav system and its Russian equivalent, Glonass.
- Its particularly important in the far north to use the Russian system. This satnav network is located further north and helps make locating a person in distress safer and more accurate, says Asle.
The oil company Eni Norway has already started using the equipment for their workers in the Barents Sea.
- The safety of employees always come first, and as the operator of the first Norwegian oil field to come on stream in the Barents Sea, is important for us to develop customized solutions, says The safety of the employees always come first, and operator of the first Norwegian oil field to come on stream in the Barents Sea, is important for us to develop customized solutions, says HSE Director Liv Nielsen from Eni Norway.
Tested as aircraft components
Hansen Protection has spent double digit millions (NOK) developing the new beacon and advanced new survival suits for the North. The company has worked closely with the oil industry to meet their specific safety requirements.
- Governments, unions and oil companies set very high standards for safety equipment to be used at sea. They have helped to test the equipment. The tests were done in a cold chamber and pools that simulate real-world conditions, such as in the Barents Sea. The equipment is tested as thoroughly as aircraft components, said Knut Åsle.
Hansen Protection worked closely with SINTEF in product development.
The company currently exports survival suits to, amongst others, Canada, China, Russia, Denmark and Germany. The most advanced suits are manufactured at the company's facilities in Moss, while less advanced models are manufactured in the Far East.
The Federal's pistol slid into its holster and his sabre flashed out. He threw its curved point up in a splendid salute. Ferry saluted with his straight blade. Then both swords rang back into their scabbards, and Jewett whirled away toward his column. For a moment we lingered, then faced to the left, trotted, galloped. Over the fence and into the road went he--went I. Down it, as we crossed, the blue column was just moving again. Then the woods on the south swallowed us up. "All right, sir." that before. Meanwhile the parallelism between Thought and Extension was not exhausted by the identification just analysed. Extension was not only a series of movements; it still remained an expression for co-existence and adjacency.412 Spinoza, therefore, felt himself obliged to supply Thought with a correspondingly continuous quality. It is here that his chief originality lies, here that he has been most closely followed by the philosophy of our own time. Mind, he declares, is an attribute everywhere accompanying matter, co-extensive and co-infinite with space. Our own animation is the sum or the resultant of an animation clinging to every particle that enters into the composition of our bodies. When our thoughts are affected by an external impulse, to suppose that this impulse proceeds from anything material is a delusion; it is produced by the mind belonging to the body which acts on our body; although in what sense this process is to be understood remains a mystery. Spinoza has clearly explained the doctrine of animal automatism, and shown it to be perfectly conceivable;569 but he has entirely omitted to explain how the parallel influence of one thought (or feeling) on another is to be understood; for although this too is spoken of as a causal relation, it seems to be quite different from the logical concatenation described as the infinite intellect of God; and to suppose that idea follows from idea like movement from movement would amount to a complete materialisation of mind; while our philosopher would certainly have repudiated Mr. Shadworth Hodgson’s theory, that states of consciousness are only connected through their extended substratum, as the segments of a mosaic picture are held together by the underlying surface of masonry. Nor can we admit that Spinoza entertained the theory, now so popular, according to which extension and consciousness are merely different aspects of a single reality. For this would imply that the substance which they manifest had an existence of its own apart from its attributes; whereas Spinoza makes it consist of the attributes, that is to say, identifies it with their totality. We are forced, then, to conclude that the proposition declaring thought and extension to be the same thing570 has no413 other meaning than that they are connected by the double analogy which we have endeavoured to explain. “Oh, he’s welcome to it,” Sandy cried. “I’ve turned over a new leaf!” “But—are they?” He pulled a wire out a trifle from the sheath. The sergeant spent more time upon the oaths with which he embellished the counter-question as to how he should know anything about it, than would have been consumed in a civil explanation. "Doctor, he can't die. He mustn't die," said Shorty in agony. "The regiment can't spare him. He's the best soldier in it, and he's my pardner." AND ENTERS UPON HIS PARENTAL RELATIONS TO LITTLE PETE SKIDMORE. "Holy smoke, look there," gasped Monty Scruggs, as a company of rebel cavalry came tearing over the hill in front, to the assistance of their comrades. "That's about it," answered Shorty disdainfully. "That's the way with all cavalry, dad-burn 'em. They're like a passel o' fice pups. They're all yelp and bark, and howl and showin' o' teeth. They're jest goin' to tear you to pieces. But when you pick up a stone or a club, or git ready to give 'em a good kick they're gone, the devil knows where. They're only an aggravation. You never kin do nothin' with 'em, and they kin do nothin' with you. I never kin understand why God Almighty wasted his time in makin' cavalry of any kind, Yank or rebel. All our own cavalry's good for is to steal whisky and chickens from honest soldiers of the infantry. The infantry's the only thing. It's like the big dog that comes up without any special remarks, and sets his teeth in the other dog. The thing only ends when one dog or the other is badly whipped and somethin's bin accomplished." "Mmm." Reuben started out of the half-waking state into which he had fallen. It was late in the afternoon, the sunlight had gone, and a wintry twilight crept up the wall. Maude the dairy-woman was looking in at the door. It was about a month subsequent to this, that one morning, as Turner was making the anvil ring with the ponderous strokes of his hammer, two retainers from the castle entered the shed, and delivered an order from De Boteler for his immediate attendance. Wat laid the hammer on the anvil, and, passing the back of his right hand across his forehead, to clear away the large drops that stood there, looked with a kind of smile at the men as he said, HoME泷泽萝拉四部和集下载
