我2010年新年前一天的潜水遇险经历,上新西兰各大报纸了头条了。希望各位潜友引以为鉴。

Swept into dark, angry seas off Wellington's south coast, a diver pleaded to his friend: let me go, save yourself, but look after my mother.
Max Ma, Han Yung Lin and friend Roy Xiong, all aged 30, were recovering in Wellington Hospital yesterday after a 16-hour ordeal that began when their dinghy capsized around 6.30pm Thursday, about five hours into a fishing and diving expedition.
Mr Ma fought the sea for more than nine hours as he swam to safety, emerging exhausted and clinging to a rock on the shore at Ohwiro Bay before dragging himself to a nearby house for help about 3.45am.
Feared drowned, Mr Lin and Mr Xiong were plucked from the waters of Cook Strait by rescuers shortly after 10am yesterday.
Speaking from his hospital bed, Mr Ma said the trio became separated after their stalled boat began taking on water and capsized within four minutes, offshore from Sinclair Head.
"I seen the helicopter three times ... but it was really dark. I was trying to scream and trying to wave."
commercial diver Mr Ma said that if it hadn't been for the efforts of Mr Xiong, Han Yung Lin – who could not swim and who only had half a wetsuit and a lifejacket on – would not have survived.
"I think Roy carried Han Yung the whole way on his back.
"Han Yang told Roy just let him go and to look after his mum."
But Roy, who had only bought the boat three weeks before, told Han Yang to save his energy overnight so they could try to summon helicopters in the morning, he said.
Police were alerted to a lone car and trailer at the Owhiro Bay boat ramp around 9pm, and a search was launched 30 minutes later, though it was hampered by the dark, choppy waters and absence of clues.
Setting out for the shore in waves up to two metres, powerful currents and winds gusting up to 90kmh, Mr Ma swam for an hour before looking up and realising he was further away than when he started.
Mercifully, the current changed direction and at 3.45am, he washed up in Owhiro Bay, too exhausted to stand.
"I was holding the rock 10 minutes. Then I just pushed myself up and make my way to the people who were living there and knocked on their door."
When Simon Baker opened his front door to find Mr Ma half-collapsed on his Owhiro Rd deck, wet and shivering, his first thought was that he was a drunk.
But as his eyes adjusted, he saw Mr Ma was wearing a full dive suit – and, through panicked gasps, was spluttering that his friend was dead.
"I said `are you alright mate?' and he just sort of half-collapsed and said `Can you dial 111, our boat's sunk and I think one of my friends is dead and the other one is missing'," Mr Baker said.
"The poor guy was just shattered, just exhausted."
Mr Baker, 35, and his girlfriend Hayley Budd, 21, helped Mr Ma inside and sat him on the couch, where they wrapped him in a dressing gown and covered him with blankets.
Ms Budd got him some hot water and Cookie Time biscuits, and the distressed diver told them how he had been swept up and down the coastline, swimming from Owhiro Bay to out near the airport and back, before he managed to get to shore.
"He was starving, and obviously really upset ... his eyes were just absolutely burning red from the saltwater."
In hospital later, Mr Ma gratefully recalled the biscuits. "They were my favourite ones, eh. I eat like half a box of them. I was really hungry."
Emergency services arrived and got Mr Ma into the shower to raise his body temperature before taking him to Wellington Hospital.
Mr Ma's emergence reignited the search, which had been called off at 3.30am. Coordinated by the Rescue Coordination Centre, it involved police, the Westpac rescue helicopter, Helipro, the Coastguard and a number of other boats.
Hewitt's ordeal sprang to mind
As he battled currents, waves and strong winds to get to shore, Max Ma thought of Rob Hewitt.
Mr Hewitt, a navy diver and brother of former All Black Norm Hewitt, survived for four days and three nights after being swept out to sea while diving off Mana Island in 2006.
`It's a really amazing story, eh. He's a legend," said a recovering Mr Ma from his hospital bed yesterday.
Mr Hewitt, who ate kina and crayfish and sucked moisture from his oxygen tank, said yesterday's rescue brought back memories of his famous ordeal.
"Four years ago that would have been me."
He hoped his unlikely survival tale and the fact he had survived after so long had helped the men as they wrestled with their own emotions.
"It's the same thing like when Sir Edmund Hillary climbed the mountain ... everyone after him knew it could be done."
The weather and cold water temperatures would have made it difficult and they would have been hallucinating, Mr Hewitt said.
大难不死,必有后福
敢问你是ma还是xiong?
必有后福啊
是你的意志力救了你,还有就是潮汐对换的时间。
lz是Max Ma,游了10几个小时的那位
10几小时。。。。
3个小时前刚刚在pg经历一场不大不小的事故。
低压管26米深的地方突然爆裂, 气瓶的气瞬间跑光,来得及去抓附近同行人的备用2级头, 但空的气瓶拽着两个人迅速向上,没有顾得上放气, 很快从26米到了水面。
在上升的几十秒里面, 看了深度表, 做了cesa,就是他nnd忘记放气。
又:
。
看到下面很多朋友问我为什么要做cesa。看来我没说清楚,大概刚上来吸氧没吸够, 表达能力受到影响
上升到8-9米的时候, 在没有放气的情况下,我已经没机会再建立中性。 着急之下, 我就开始吐气“啊。。。”(后面鲨兄说了, 因为忘记放气, 已经到了不能控制的地步,这不算cesa), 以为起码不至于爆肺。被我抓住的同伴, 估计还是正常在吸气吐气的。
正确的做法是不是应该:马上头朝下,倒过来,用脚蹼打水控制升力,然后再考虑放气的事?
你是哪一位啊,先慰问一下。
这个话题在我们这桌上也引了讨论,呵呵。产生了好多的问题,也产生了好多答案。明天餐桌上聊啊。
惊心动魄啊
看不懂
下水前BUBBLE CHECK气泡检查。。。。
如果是我在已经吸到buddy气的情况下设备拽我上冲
我第一反应可能是脱掉bcd...
不过你cesa的时候,和buddy一起cesa???
恩,我想错了,气瓶气放光是增加正浮力的。不好意思。
一瓶气,在200Bar和0Bar之间相差大约3公斤的重量,http://en.wikipedia.org/wiki/Diving_cylinder。加上女生体格较小,相差3公斤是真的会照成不受控制上升。
如果可以,BCD不打气就不会有这个问题,打了气紧急上升就要记得放掉。CESA 的意思就是紧急控制模式游上水面,也就是说一秒钟不可以超过一尺,最近更有说法是慢一倍更好。上升的时候如果是控制不到自己的,就算是嘴里“阿”个不停,也不算是 CESA。
我估计鲁西西应该是已经潜了一段时间,都到了28米深度,所以漏气增加的浮力应该不到3公斤。
看来还是调整好配重,下潜过程中BCD尽量不打气比较安全。
我的新年第一天也是泡在水里。
没出事故的时候都是无比的哈皮
警钟长鸣啊~
看了LZ的描述,还真有些心惊肉跳啊。。。朋友那句照顾我妈妈的话让人读了心酸。
为了自己和家人,大家都要平平安安的!
鲁西西所说的情况,应该拉住快速排气阀放掉BCD的气,那么即使空瓶了,也不会一下子冲到水面上。
建议大家在满瓶时和dive结束时都做buoyancy check,保证50bar左右配重仍能满足负浮力才好。
这样的配重即使空瓶基本也足够了,至少不会迅速上浮。
如果是inflator卡住了导致BCD充气,就要立刻拔掉hose
脱BCD这个做法……呃,不建议……有许多其他快速有效的方法,脱BCD太慢了且有其他潜在风险。
是接bcd的低压管爆了。
我摸了摸管子的裂口, 还试图用手去捏住, 发现完全无法处理,气瓶的气很快就没有了,前后最多30秒。 当时离我最近的同伴离我一个身位,还好我打了一下脚蹼, 就能赶上他, 拉到他的脚蹼后马上示意我出了问题, 一把抓对方的备用头。
吸到气以后,以为没事了-当时也就潜了13、4分钟的样子,大家气量都还足够。但是没有马上意识到浮力变化的问题,只摸了摸bc, 觉得里面没气,后来上升速度明显加快,可完全忘记拉放气阀。给我备用的同伴被抓得死死的, 也没法放气,两个人中途看了一下电脑表, 很快从26米到14、到8米,明显失控, 能想到的就是拼命吐气, 以免肺也爆掉。
睡了一下午的觉, 醒来后仔细想了想, 当时处理存在的问题。
1、没有本能地反应到浮力变化的问题, 有一瞬间居然还闪过“是不是需要丢一个配重"的错误念头。
2、一发现快速上升后, 有点乱, 以前遇到的最大问题就是5米停留, 所以上升过快时容易慌。
3、慌乱中忘记拉放气阀门,这直接造成急速上水的严重后果。
4、抓同伴抓得太紧, 传递了紧张的讯息给对方,以至对方也不自觉地惊慌。
呵呵,吸到buddy的气的时候,放气绝对是第一位的。
不过第一次遇到紧急情况肯定会慌乱的,这个主要还是靠经验
安全就好
鲁西西这个事故也很恐怖啊! 潜水真是一项高危活动! 越看越害怕。。。。
不过鲁西西一直没有回答是潜店还是自己的装备?
看着lz游了近十个小时才到岸边,无比惊心动魄!必有后福!想知道你是穿着脚蹼带着面镜呼吸管吗?如果神马都没有可是太厉害了!
没想到西西会碰到这种意外,没出大事也算幸运!这是极低概率的事件,在那种情况下很难有正确的判断,没事就好!
看得很惊心动魄,虽然潜水也有些年头,但是我也一样不确认自己遇到同样事情是否会冷静处理,谢谢分享。很关心你那个可能没有cesa,估计正常呼吸被拖上来的伙伴情况,他还好吗?
多谢cc姐。
同伴上来有头痛症状,我没什么反应。我们吸了三次氧, 现在完全恢复了。
请问下lsd下潜一共多长时间?最大深度多少?上来有减压舱减压么?
遇到这种倒霉事情,跟本没有什么时间反应,bcd要是无配重的话脱bc,有配重的话只能看潜伴能不能帮及时及割开bc背部了。潜伴刀也要够快,用这种能割电缆的潜水刀一刀就可以完全把bc割开瞬间放气的 http://www.chinadiver.com/sns/space.php?uid=4644&do=album&picid=73680
哥们儿你出事没两天就开始上网啦,精神甚好!
