Boarding the dive boat Cdt. Fourcault style!

Tuesday, July 14th, 2009
Look Ma, no ladder!

Here’s a little video clip showing the diver boarding procedures used in the North Sea aboard the Cdt. Fourcault.

Ascent is not up the anchor line, but on a drifting “shot line”. At the top is a large (4 ft) ball. Attached to the ball is a tag line. Once you hit parco acquatico gonfiabile the surface, you hold onto the tag line waiting to be picked up. The RIB picks up one diver at a time and bring them back to the mother ship. Attached to the back of the RIB is a foam raft (boogie board). The diver climbs aboard the raft, and the RIB heads back , diver in tow. In 8 ft seas, this is quite an experience.

Once alongside the diver rolls bouncy castle for sale off the raft, and drifts over to a cage/platform that is lifted up onto the main deck. No ladder!

North Sea Expedition 2009

An Exceptional Dive Platform

Last week, a few friends and I had the opportunity to join the North Sea Expedition 2009. This was an all CCR trip to visit some untouched wrecks. The trip was coordinated by a group of Belgium divers who were gracious enough to invite groups from the UK, parco gonfiabili and the USA. The dive platform was the Cdt. Fourcault, a 150 ft converted military vessel. The owner/captain, Pim, lives aboard with his lovely wife Angel. They hosted the entire group in their “home”.

At the beginning of the week Pim made a comment that the highlight of the week is not the diving, but the people. His words could not have been more accurate. I’m not down playing the diving, but it was overshadowed by the people we met. First, the Belgium dive group did a fantastic job of putting this trip together! I can not say enough about how smoothly and professionally this was carried out! Not only did they plan and coordinate the diving, but also supplies (tanks, weights, sorb …), transportation, and even dinner plans in town. Second, Pim and Angel were two of the best hosts anyone could ask for. Can you imagine having over 20 people staying in your house? Meeting, diving, and spending time with them was one of the trips highlights! They also had a great crew assembled for the trip. They all kept the ship and dive operations running smoothly, and safely all week. In addition they were fun and interesting people to meet and work with.

Group Dive Brief

In addition to our hosts, many other great divers were aboard for this trip. We spent long hours laughing and talking about trips, techniques, and gear: what works, what doesn’t. Just a great group to spend time with.

Now lets talk about the diving.

Dive operations were very different from here in the Northeast US. We have some areas around inlets and sounds (Block Island and Rode Island for example) where dive operations must be scheduled around the slack tides. In the North Sea, all dive operations seem to revolve around the tides. There is a dive window of around 2 hours. At the start of this window the current is dropping down to a manageable range. During the dive the current eventually stops completely, and reverses. The trick is to get back on the line before the current picks up and becomes unmanageable.

Drift to the shot

To operate in these conditions, divers use some different techniques than we use here. The ship does not anchor into the wreck. Prior to dive operations, shot lines are dropped on the wreck. Theses use large weights, and grapnels to drop quickly to the bottom, and hook the wreck. Next the dive vessel is positioned up current of the shot line. If possible, the vessel will anchor in this position. However, based on wind and current, this may not be possible. Divers then jump in and drift to the buoy on top of the shot, then descend to the wreck. The first divers secure the line into the wreck. Each diver attaches a marker to the line, and removes it when they head back up. The last diver unclips the line, and the entire group drifts with the shot line.

Giant stride!

A few techniques that are specific to the Cdt. Fourcault: Jumping into the water involves a 12-15 ft drop from the main deck. Now that’s a Giant stride! Any time divers are in the water, one of the three RIB is standing by to assist. At the end of the dive, the RIB can bring the diver back from the shot line. If conditions are right, the diver can simply drift back in the current. Once alongside the diver swims into a platform that is lifted up onto the main deck. No ladder!

Look Ma, no ladder!

This combination of techniques allows for operations in much heavier seas than we would normal consider locally. Since the sea conditions on the North Sea are normally rougher than we experience here, this is a necessity. The US divers were subjected to a trial by fire on the first dive. Jumping into 8 ft seas and swimming to a buoy barely visible between swells. Once there we descended to the wreck into a strong current. On the wreck we enjoyed searching about for artifacts, as well as seeing an abundance fish life different from our own. During the ascent, we hung on the line like flags in the wind. After the shot line was unclipped we then drifted along like plankton. Back on the surface, we bobbed about in the swells until, the RIB picked us up, one at a time. Attached to the back of the RIB is a foam raft (boogie board). The diver climbs aboard the raft, and the RIB heads back to the mother ship, diver in tow. In 8 ft seas, this is quite an experience.

Riding the Boogie Board

The Dives:

Again, I must say thanks to the Belgium dive team for their work in lining up a number of great dives. Many of the wrecks had not been dived before, and we all accepted that they may or may not be worth the effort. For the most part the risk was worth the reward. Conditions on the bottom varied from 10 ft to over 30 ft of visibility. One advantage of the strong tidal current, there is no thermocline. The water was 60 deg F from top to bottom.

Some of the wrecks were intact or nearly so. Others were debris fields in the sand. One wreck was completely engulfed in a sand bar, leaving only the bow, and small tips of debris visible. Others stood up prominently, providing large areas with easy penetration. Here inside the wrecks many artifacts were recovered. Portholes, plates, bottles, spoons, placards, even a telegraph, were all brought into the daylight for the first time in many years.

I’ll try to add more details on individual wrecks, but this post is long enough. Let me end by saying, it was a great trip! Good dives, good friends, good Belgium beer.

Scallops, Lobster, and Training on the Lillian.

Tuesday, June 9th, 2009

The Scuba Connection had a charter to the Lillian this week.  Wayne was out with a class. With a few of the usual suspects in tow, the Independence got underway.   NOAA was calling for thunder storms in the afternoon.  The drive out of the inlet was in heavy fog.  Once that open up, we could see on the radar that the rain was following us out (a bit early).  The worst of it hit before we got to the wreck, and mostly cleared by the time Richie had us tied in.

The passengers soon rolled in, and Richie returned with a nice bag of scallops and bugs.   He had us tied into a large pipe next to the engine.  This section of the wreck stood some 20 ft off the silty bottom.  The surface temp was 58.  Bottom temp was 43-48, depending on who you asked, and visibility was a dark 40.  If the sun came out, this would be a fantastic dive.  As it was, it was just great.

The Lillian was a freighter that sunk back in 1939 with a cargo of sugar. It sank in 150 ft of water after a collision in the fog.   The wreck is on the edge of the mud hole, so the conditions can vary depending on the tide.

After seeing all the scallops coming up, I figured I’d have to go out bounce house for sale in the sand to find any.  This proved futile, as the scallops were on the wreck itself.  Once I figured this out, I bagged my share just as my reel decided it did not want to go any further. Flounder were all over this wreck.  Some were so large, I had to check twice.  Many were still buried in the sand.  Those I checked three times.   Ling cod were also about, along with a few Eel Pouts.  One unusual item was the large sponges lodged about the wreck.  These seemed out of place here.  Some were close to 3 feet across, just laying in the sand.  Captain Dan told us to keep an eye out for portholes, so I looked closely as I reeled my line back in.

I headed back to the boilers, and was soon comforted by the sight of the strobe in the distance.  These were great conditions for this wreck.    Back on the boat, we all took turns cleaning scallops.  Several of the passengers had bagged their first scallops, and were learning how to clean them under Captain Dan’s tutelage.

We headed home just as the sun broke through the clouds.  Oh well, it was still a great dive!  The scallop dinner was good too!

Black Friday dive on the Independence II

Saturday, November 29th, 2008

With full boat, the Independence headed out for a Black Friday dive. Most of the divers were surprised at the number of other divers aboard. It was probably the result of many people having the day off work, and a favorable forecast. Everyone seemed happy to get in another dive for the season.

We were shocked to find that NOAA’s forecast was not exactly accurate. The front they were expecting to pass during the night had done so later than expected. We were faced with a swell from the southeast, and wind from the southwest. Given the conditions everyone agreed to changed the intended destination and headed to the Mohawk. The swell stirred up the bottom a bit reducing the visibility to 25 ft. The water temp had dropped from 54 degrees last week to 50 degrees. Some say the surface temp was a bit lower, but I did not take note of it.

By the time I splashed, some of the other divers had started to surface with some nice size tog and a few lobsters in tow. The report of 25 ft of vis, swell, and low light from the overcast sky made me decide to leave the camera onboard.

On my way down, I passed the remaining divers coming up the line. The bottom quickly came into view, but I had to give my eyes a few moments to adjust to the low light. The last time on this wreck the current had pushed me to the starboard side. This time it was to port. Now I could check out the rest of the wreck.

Frankie had us tied in next to the boilers. I started heading aft past the engine and stern, then doubled back toward the bow. From the last dive, the debris on the starboard side of the wreck had been mostly gear and cargo. Here on the port side, the debris bouncy castle for sale consisted mostly of hull. Ribs and strakes stood up out of the sand making navigation in the surge a bit of a timing issue. In the lea, there were small schools of fish taking refuge. Most of the larger sea bass and tog were hiding under the debris. Normally they are still active when the water is this warm, but they may have been waiting for more daylight to hunt for food.

Before long the bridge loomed up out of the center of the debris, an indication that I was approaching the bow. Here and there were balls of rope and netting swaying back and forth in the surge, almost looking alive in the hazy distance. The bow section was again surrounded by a school of cunners and juvenile sea bass. This time, I could not see from the base to the tip, and in the darkness I almost did not recognize where I was.

I started heading back to the stern. At several points I headed out into the sand to see if the small pieces of wreckage might contain lobster. I was repeatedly disappointed. Soon, I noticed that I could no longer hear the sound of bubbles in the distance. Figuring that the other divers were done their second dive, I headed to the line and just as I started to ascend, it went slack. I guess that means I’m the last one in, and it’s time to pull.

When I broke the surface I noticed that the swell had subsided, and wind seemed to have died down. We were soon headed back in much calmer seas, but the air temperature had dropped significantly. Chalk up another one for NOAA, but was still a great day of diving.

Wreck discovery on the Indepencence II

Thursday, October 16th, 2008

The Independence II headed out this week on another wreck exploration trip. Captain Dan Bartone had obtained some promising hang numbers a few weeks back. They were located within a few miles of three known Black Sunday wrecks, and warranted further investigation. We’ve tried to get out a few times, but Neptune had his own ideas. This week the weather cooperated. Dan assembled some of the usual suspects (Dive Marshal Bill Trent, Richie Kohler and Dave Oldham), and headed over 50 miles offshore to check them out.

We arrived to sunny skies and clear warm water. Bill and Richie jumped in and tied in to the wreck in 230 fsw. The report came back that the current was ripping the whole way down to the wreck. While Richie swam along the wreck in an attempt identify her, Inflatable Water Slide Bill had other priorities, and completely filling his bag with lobster. Quite literally, one more lobster, and the bag would not close.

Dan and I splashed to check her out, and pull the hook. With the reports on the strong current, I opted to leave the camera topside. This was a good call, as the decent was hand over hand all the way down the line. We reached the bottom to find 40+ ft of vis, 47 degree water, and reasonably ambient light for this depth. We were tied into the bow winch with her boiler near by. What appeared to be the bowsprit could be seen a short distance off in the sand. This and other structures showed evidence that she was a sailing ship. We were not able to make it to the stern, given the current and the alloted time, but she appears to be over 150′.

We were quickly out of time, and had to get back to pull the hook. Dan and I spent the next hour+ decompressing in the 65 degree water. It felt comfortable to me, but Dan had a leak in his drysuit, and was chilling quickly at 30′. We got on board and headed back home.

Sunset at Clark’s

On the way back we all discussed the nature of the wreck. She’s a low lying, wooden sailing vessel which means that identification will require some digging. Her position is within 10 miles of the charted position of three other Black Sunday wrecks. Could she be one also? Only time will tell!

We arrived home to a beautiful sunset, and hot lobster dinner!
