sha1406032813sha1406033434sha1406033401I’ve been working in the G.O.M. for the last 16 months or so and regularly find myself making that long transit from the Dry Tortugas to the Southwest Pass of the Mississippi River.  The trip is more or less a great circle extending 400+ nm.  The first few times I made the crossing I noted that I would have an extreme “crab angle” due to the influence of the current known simply as “The Loop” aka a parent source of the Gulf Stream.  Sometimes I’d be steering upwards of IMAG162815 degrees into the current in order to make good my charted course and struggling to make any real speed.  Sliding across the Gulf is the rule.

There’s little doubt that this is old news to the guys who have been working the gulf for years, but it was a real surprise to me.  I mean, I expected different, but not to this degree.  Banging up against the Gulf Stream makes for slow going, no real mystery there.  And running with the stream is amazing in that your speed exceeds anything you thought the boat could do…but the loop?

The “Loop” is a current in the Gulf  of Mexico and flows at greater or lesser velocities as the seasons change.  It is known to meander widely and is formidable enough to knock more than 3 to 4 knots off your speed.  Meander is a gentle way of putting it, one watch you’re cruising nicely, next you’re wondering if the wheels fell off…  It’s seems to be all over the place, but with satellite imagery and telemetric magic it can be tracked.  And if it can be tracked it can be planned for.  Soooo for  those of you who know all about this, need read no further unless you’d like to proof my work.  In which case I will gladly accept any additional clarifying data you’d wish to provide.

The information one needs in order to visualize and to take advantage of / or steer around this current  has been available, but the resource (available in the form of “pilot charts”) only gives a general overview of the current by the month.  Honestly, I didn’t find them all that helpful.

My colleague gave me this link that provides just the kind of data you can use.  The site is paid for by our tax dollars and in my opinion money well spent.

You’ll need to make certain your security settings in your browser allow java applets to run.

The initial page gives you the overview which you can select a geographic area and what you’d like to see.  If you just want velocities, click it.  If you want to save the data as an image, select .gif format.  The smaller the geographic area, the easier you’ll be able to interpolate the lat and lon grid.  (I use MS Paint to overlay the more detailed lat/lon grid, it’s a bit tedious but yields an reasonably accurate grid to pick off waypoints)).

Note the red grid over the gulf.  you can resize it as you wish and pick the day average as well.  I usually use a 3 day average.  Once you’ve made your selection choose .gif if you want to save the image.  After that, you can eyeball the route you want to take and then identify the waypoints you’ll need to hit to go around the adverse current or to take advantage of a following current.

This will assist in selecting a course around the higher velocities and hopefully save some time on your next transit.  Sometimes a few miles out of the way can save more than a few hours, an all important option when it’s close to crew change.  After all that is the most important consideration….just sayin’

I’m beginning my radar renewal process a bit early this time using the Calhoon MEBA Engineering School Distance Learning Program.
When I wrote the last article describing this new way to handle training and re-certification I said that I would be giving this a try as my renewal date approached.

I should say that my first attempt at finding and registering for the course was slightly side-tracked by the fact that I thought I would be using the Prometric portal.  Well let’s say that after a few calls to an endless loop of phone menu items and toll free calls including one to somewhere in southeast Asia, I found my way by calling  the Calhoon MEBA School directly and spoke to a nice young woman named Lisa Mc Neil.  (410-822-9600 ext 322).  I was able to ask all my questions and get answers from a real human being and I was set right in short order.

So here’s the deal as I understand it;

Any mariner can apply for their radar re-cert with this school, you do not have to be a member of MEBA.  Follow this link to their home page, hover your mouse over the “Online Courses” menu item and check out the drop-down menu.  Read everything then fill out your application, select your course and pay the lady.  You’ll receive an email with confirmation and then you’ll have to allow a day for processing the order.  You will receive an email confirming your registration and access to the study material and also (more importantly) your login and access to the instructors for any questions you might have (via email).

In the information link it states you have a month, but the conversation I had with Ms. McNeil made it clear that I could study longer if necessary and not have any problem.  Ms. McNeil can offer more info if you need more time.

Once you have registered and been accepted you will be given the key to the online course material and practice with it as often as you like.  The online course and testing material comes from the same source used at the Prometric Center on your exam day.
Clipboard01Okay so you’re ready to test.  The scheduling process is email based and finding the exam near your home becomes your next step.  Here’s where the Prometric System comes into play through the Calhoon website.  
Select “Locate a Test Center” and follow through the menu to filter it down by country, state, etc…

Select the course;

Clipboard01a

Search the nearest test center;

Clipboard01b

Select the center you want;

Clipboard01c

Check for available dates

Clipboard01d

Clipboard01e

So that’s what I’ve got so far.  I will report back after I’ve completed the process and let you know how it went.  So far I’m on track.

It’s been a few months and the weather conditions down here in the Gulf of Mexico continue to offer a diverse experience from one voyage to the next. Here’s what we had to deal with for a day and a half just before the Thanksgiving Holiday.  What you’re watching is what an ATB is designed to do, ride weather that would keep a conventional tug and barge hove to on a slow ahead engine or weather bound all together.   We don’t necessarily enjoy this kind of ride, but the fact the ATB tolerates this kind of weather and is still able to make a respectable amount of headway is testament to the effectiveness of the design.

A line tow ready to head upriver, his length overall is about 1,500 feet and maybe 120′ wide.

I have to admit I’m a bit of a tourist these days.  My latest assignment has my boat trading between New Orleans and Florida.  As I write this we’re waiting to get a loading berth in the NORCO terminal just above the Crescent City.

While I’ve been around tugs and tows my entire career I’ve never had the experience of seeing a Mississippi river tow built and then sailed by the massive towboats that navigate the lifeline of the mid-west.  It’s busy work and takes a lot of blood and sweat to put together.  It can take a day or two to build a “line tow” by small workhorse towboats that are in constant motion picking up, shifting and rafting up a fleet of 28 or more barges carrying anything from coal to grain to whatever.  The towboats that move the finished tow are huge and wide with a good amount of horsepower in the engine room and the pilothouse.

Listening to these boats receiving their marching orders is interesting, the numbers and types of barges vary from boxes to rakes and keeping track of where they are placed and how they are delivered is complex but well understood.  It reminds me of how my Dad used to get his orders moving railroad floats for the New York Central when I was a boy just riding along.  The numbers of each unit are conveyed in a boatman’s shorthand, concise and exact.

The volume of traffic here is amazing. Ships, sea-going and river tows are everywhere.  Huge cranes off-loading dry cargo, flotillas of barges are almost everywhere along the riverbank.  The anchorages are along the river and tightly packed.  Our anchorage here in Ama one of many.   We set our anchor within a few dozen yards of the unit ahead of us and settle back.  The river current is constant so we lay parallel with the bank.  It’s a bit unsettling to be this close to the guy ahead of us and the one behind us, but the anchor holds and it’s kinda cozy.

The radio chatter is flavored with a bit of a patois and it’s amusing to hear some of the exchanges between the pilots and operators of the boats working here.  Courteous and occasionally colorful these fellows use phrases that catch your attention.  In a conversation between a couple of units this morning the dialog went something like this;”I’m up-bound approaching the turn, what would you like?” If you could hold up there I’ll be around here shortly”, “No problem cap, I can do anything but disappear.”  You can be sure I’ll be using that one someday.

It’s not news to anyone that’s the least bit familiar with the western rivers that the “line tows” are massive floating collections of cargo larger and longer than any ship afloat.  To listen to these units making their way is a study in “cool and calm”.  When I encountered my first big guy, I was impressed  with the way he seemed to manage his charges so effortlessly.  I quickly recognized that these men were supremely gifted boat handlers and to underestimate them would be foolish.

For the time being, I’m going to enjoy the experience and absorb as much as I can from the mariners that work in this corner of the country.  These people have a skill set that rivals any you might find in the Northeast.

During my first voyage here one of our river pilots came aboard to relieve his colleague who had met us at the entrance to the river eight hours earlier.  As we shook hands and in a big voice he said “Cap, your day just got better”, better indeed.

More to come.

My first voyage to the Mississippi River was a fine fair weather trip around the Florida Keys and across the Gulf of Mexico.  I shot a few pictures and learned a few things.  More on that later.  For now, some photos..
