Wave power scheme to get AIS

Following proposals announced two years ago to construct a wave power scheme around the Isle of Wight using Pelamis "sea snake" technology, concerns were raised about the risk of collision. Despite the interlocking metal cylinders being painted bright red and having radar reflectors alternately in the 'point up' and 'rain collecting' position, it has now been agreed to add AIS transmitters to the scheme. These will have battery backup so that they will continue to transmit for up to 48 hours when the sea is calm.

On chartplotters and laptops with AIS overlay, the scheme will be displayed as an animated snake in the same shade of pink as radar overlay. Laptops with a sound card/speakers will also be able to emit an audible warning which gets louder as proximity to the scheme increases. Default sounds include a lion roaring and a snake hissing. You can also record your own sounds (appropriately in the .wav format) so for example you could record your other half saying (in increasingly urgent tones) "You're too close." "YOU'RE TOO CLOSE!" "AAAARGHH!"

It is hoped that the scheme will be installed and functional within one year.

There's no need for the snake to carry the AIS transmitters, they could be ashore. The transmissions just have to have the right coordinates. So if they are fitting AIS tranponders to the snake, it suggest the snake swims around quite a lot. Up tide to down tide positions.

I think we should all be concerned about the risk of collision with new offshore wave and wind farms, especially if we are a bit slack about keeping our charts up to date. Presumably wind turbines could transmit on AIS also, although perhaps a static icon would be more appropriate...

I think this is a very sensible idea, presumably the AIS will also transmit the DATE and time as well as location... /forums/images/graemlins/wink.gif
