Probably
the most freighting night of my life was spent at sea. We were off
the coast of Charleston S.C. on board the research vessel R/V
Atlantis II, operated by the Woods Hole Oceanographic Institution. On board
was the 3 man deep diving submersible, Alvin, for which I was a pilot
and recovery swimmer.
We
were new to this ship having just spent the last 8 months
transferring Alvin from the R/V Lulu, a 105-ft. catamaran and a ship
of limited ability. The Atlantis II is a 210-ft. vessel with twin
screws and a bow-thruster and a much more capable and comfortable
vessel. Alvin is recovered by a large 44 ft. A- frame crane that
hangs over the stern of the ship and lifts the sub from the water and
swings it inboard to set it on deck.
Alvin
is owned by the U.S. Navy and they have the final say as too how
operations are conducted. One of the things they insisted on was that
we should do 50 unmanned launch and recoveries before they would
certify the A-frame for manned use.This meant launching the sub and
opening the hatch on the surface to get the pilot and 2 observers
inside. The reverse was true for recovery. A 17 ft. small boat was
used to shuttle personnel from the ship to the sub.
It
was early in the year so it got dark around 5 PM. We had come down to
Charleston from Woods Hole to escape the cold of winter and complete
the set up of the sub on our new mother ship. On the 3rd
dive ever done from the Atlantis II. we launched Alvin in a 6 ft.
sea and it dove to a depth of about 3500 meters. At this depth it
takes Alvin about 2 hours to reach the bottom and the same amount of
time to transit back to the surface.
On
this day the sky was heavily overcast with a temperature in the low
50’s. Towards the late morning the seas began to build rapidly and
it began to rain hard. At 2 PM, The crew chief, Dudley Foster called
down to Alvin that the weather was deteriorating rapidly and they
should surface immediately. By the time they reached the surface the
seas had now built to 18 to 20 ft. These are really big waves. One of
the most dangerous parts of the whole operation is the launching of
the small boat. We were just able to do this. Craig Dickson was the
coxswain on this recovery. Once the small boat was in the water it was
too rough for my swim partner, Jonathan Borden and I to climb down
the ladder into the boat so we jumped from the side of the Atlantis
II and swam over.
Now
let me tell you, if those waves looked big from the Atlantis II they
were down right mountainous from the small boat. All three of us had
to wear divers' masks to be able to see as the rain really hurt on the
face. We would race to the top of a wave, have 3 seconds to look
before the nose of the boat would drop and we would scream down the
other side only to surf up to the top of the next one.
We
were getting nowhere fast. After close to a half-hour of this we
still had not spotted Alvin. The Atlantis II had a VHF direction
finder and was able to vector us to the vicinity of the sub. Once we
located it, Jon and I swam over and got aboard.
Normally
the coxswain will drop you 10 ft. from the sub but on this night, given
the sea state, Craig dropped us about 50 ft. away. On any other day
day this would be an easy swim, but in 20 ft. seas with 35kt winds
and heavy rain it was somewhat difficult.
We
had the sample basket safety lines wrapped around our waists and I
was holding the sound powered phone above the water while swimming to
the sub. The sound powered phone is used to talk to the pilot from
the outside. When the phone gets wet as it did this night, you have
to take the mouth piece and the ear piece out of the handle and bang
the water out of them. Trying to do this while hanging on for dear life
as the wildly lurching sub rose up on these huge waves was no simple
task. Once I made contact with the pilot inside who on this day was
the chief pilot, Ralph Hollis, we had to attach the basket safety
lines. These are 10-ft. ropes that you have to hook up from to front
of the sample basket to the sail to prevent the basket from
accidentally falling off. The basket is located on the front of Alvin
about 8 feet below the surface.
Trying
to swim down through the churning seas to do this was almost
impossible. We got one line on and decided that was going to have to
be good enough.
I
get back on the phone to the pilot and tell him that there is several
inches of water over the hatch. That’s just tough he says, as we
still have to get the 3 people out. By talking to Ralph on the phone
and him talking to Capt. Baker on that ship by radio it’s decided
to let Capt. Baker try an idea of his. He begins to sail the Atlantis
II around the sub in tight circles trying to flatten the seas out a
bit. He does about 4 circles around the sub and from my point of view
nothing has changed. Of course the view from standing on top of the
sub is pretty grim anyway.
The
decision is made to open the hatch. When it flies open the 2
scientist come out like they are shot from a cannon. No one wants to
be trapped inside if the sphere floods and make one final trip to the
bottom. Ralph is the last one out. He slams the hatch shut and
secures it. Back on deck we will find 10 gallons of seawater inside.
This does wonders for the electronics.
There
are now 5 of us standing on the outside of the sub as Craig comes in
to pick up the crew. Once they are safely in the small boat the
Atlantis II sets up for its recovery approach. What they will
normally do is pass a towline to the small boat and they will bring
it over to Alvin. The swimmers then hook it to the sub and it is
pulled in until it is beneath the A-frame with its lift-line.
There is
no way that was going to happen today. Instead they streamed the towline
out behind the ship and cut across our bow. We will then grab it as it goes by and hook it up. This has never been done before but by
some stroke of luck we get it done in the first pass and the begin
hauling us in.
It
was bad enough standing on top of the sub in these seas but now as we
are being pulled towards the ship the sub is actually pulled under
the tops of the waves. Jon and I are forced to stand behind the sail
and time holding our breath as the sub is pulled under at the crest
of each wave. Between wave peaks we have a few seconds to yell
encouragement to each other over the shrieking wind. We just can’t
believe we are in this position. In the end we can do nothing but
make jokes about it. We’re both scared and not trying to hide it.
The potential to be killed or maimed is enormous.
We
are rising up to a point that we are looking down on the crew
standing on the ships deck. A few seconds later we are straining our
necks to look up and see them. All the while we are being pulled
closer to where we will be beneath the A-frame. The very hard steel
A-frame.
Eventually,
we are 10 ft. from the stern of the ship and rising so high that I
can reach out and touch that steel. There are 2 lines to attach to
Alvin. The stern line is 1 inch thick and has a 5 lb. steel hook at
the end. The main line, which will go on first, is a 4-inch thick
synthetic rope with a soft loop in the end. When it comes down it’s
like grabbing a 150-lb. piece of well-cooked pasta. It’s very soft
and floppy. It takes both of us to manhandle the loop around big
titanium “T” just aft of the sail. As the sub rises, all the
slack in the line falls on top of me but the line must be held in
place. When the sub falls to the bottom of a wave that line comes
taut and turns as rigid as a steel pipe. This sequence repeats itself
over and over.
While
I tend the mainline Jon turns aft to hook up the stern line. I am not
paying attention to Jon but I see the crew on deck yelling to get my
attention and look aft. No Jon. He was swept overboard by the last
wave and I am left standing there by myself.
The
A-frame operator has now taken a lot of the slack out of the main
line and it looks like the constant tension winch will stop the loop
from falling off the big “T”. I turn around and there’s the
stern line swinging in the wind. Without thinking I fall flat on my
stomach while grabbing the hook on the way down and snap it into
place. No sooner does the hook snap into place and my world is upside
down, sideways and free-fall. That last breaking wave has swept me
from the back of Alvin and I am tumbling into the water.
This
whole event is being watched by the people in the small boat. Craig
has already picked Jon up and has never lost sight of me. As I break
the surface I hear Jon calling “are you all right?” and Craig
brings the boat right up to me and they haul me aboard just in time
to see Alvin being lifted clear of those murderous seas and set
safely on deck. But the party is not over yet. We still have to get
back aboard the Atlantis II.
As
I said before, getting into the small boat from the ship is difficult
and dangerous in these seas. Getting back aboard is even more so.
Instead of the usual ladder to climb up the boson has replaced it
with a cargo net hanging over the side. This will give a lot more
hand holds to grab should any one fall. The Atlantis II steers a
course to give us a lee on that side of the ship and Craig brought
the boat along side. Once close enough Jon and I throw bow and stern
lines to the waiting deck hands. We rise up high enough on each wave
to almost step onto the deck. It’s at this peak that you have to
time your jump. You have to time this right; you only get one shot.
The scientists are the first to go and are helped over the rail by
the deck crew. Ralph is next followed by Jon then me. The crane hook
is then lowered to Craig who hooks up the boat and stays aboard while
it is hoisted from the sea and set on deck.
Now,
after using up a 2-year supply of adrenaline, I’m sitting on the
deck with by back against a bulkhead, dripping in my wet suit trying
to figure out why I’m still alive. The chief pilot walks up to me
and says “ The starboard lower light is out and the port
manipulator doesn’t work. Fix them before you knock off.
Oh well. I
guess that’s life in the Alvin Group!
