ENOS with Net and Double Mission
The rescue system accomplish 2 tasks for BSHRP
Not frequently, however, ENOS-Beacon is also attached to the ghost-nets after they were cut and separated off the wrecks and prior lifted up to the surface.
One hour ascending time
The wrecks are located deep in the Baltic Sea and it costs a lot of time to remove the huge ghost-nets. Long decompression stops are the consequences: Despite of mixed gas it happens that Sabine Kerkau and her team has an ascending time of one to two hours prior surfacing. During this time the ghost-nets drift alone on the surface. Captain Linas can’t follow to pick them up because of safety reasons he has to keep the boat above the dive spot. Due to the deep location of some wrecks sometimes he cannot anchor.
Great danger for other ships – nerveracking decisions
For Linas it’s always a challenge when the ghost-nets arrive at the surface. Drifting nets are a great danger for all vessels. Immediately each ship is unmanoeuvrable and helpless exposed to the mercy of wind and waves if a net get into the propeller! Not to speak about the economic damage.
There have, however, been cases, where Linas had to leave the divers during they took decompression stop in the open water of the rough Baltic Sea, because he must pick up a ghost-net which was drifting towards the shipping route. This required immediate action from Linas. He had to salvage the drifting net prior merchant marine vessels became jeopardized in the high frequented shipping route …
Under Argus Eyes of Russia
The situation is made worse by the nearby border to Russian territorial waters which must not be exceeded in any case! From the beginning on Kerkau and her crew were strictly observed from the Russian border guards during their important archaeological work. "Everybody of us feel these eyes", the tough leader of the expeditions laughs. "There are just a few hundred meters to Russia but a passage of border would have significant diplomatic consequences – whether due to the ghost-nets or because of us. That’s why we all cherish double to ENOS!"
ENOS for divers and for nets
The reason for this appreciation is that the divers attach an ENOS-Beacon to the net prior lifting it up to the surface. Here, all 15 seconds the beacon relays its precise GPS position to the ENOS-Receiver onboard. So the nets are always in the view of captain Linas. "This makes our job much easier", summarizes Kerkau. "Not only that we the divers are found promptly in case of emergency. But also because of the fact that the ghost-nets don’t go lost anymore. Sometimes the nets drift very close below the surface which is rather dangerous. Now we always know where they are thanks to ENOS-System."
