As we begin the month of November those of us that work in and around the water have to start planning for seasonal changes and the accompanying cold weather challenges.  Water temperatures begin to drop rapidly, sometimes over a degree Fahrenheit (F) per day.  This presents a whole new bunch of logistical and safety risks. 

We live in a world where focus on construction safety is advancing as rapidly as the development of new microchips.  When it comes to safety, a construction company cannot afford to learn by mistake.  Reacting and correcting is not a sustainable method to our survival in this day and age.  We have to look forward and predict problems before they happen.

Traditionally when it comes to installing sheet piling around a bridge pier or along an embankment we think of steel sheet piling.  Steel sheet piling are the most common, and have been one of the most effective methods of installing a deep foundation.  They have a long history of providing a robust barrier through shaped, interlocking sheets that can last for 75+ years. 

            Hydrographic surveys are a very effective way to map the bottom of a river, lake, or other water body.  By using some of the latest technologies a 3-dimensional model can be developed to show contours, obstacles, scour areas, and large debris.  Even in the most turbid conditions, a hydrographic survey done correctly can be very effective. 

Our final installment of becoming a tow boat master focuses on the demanding schedule that one will encounter if he or she chooses this path. It is not an easy schedule, but the rewards have drawn many. 

We continue our series on becoming a Master of Towing Vessels by next addressing the duties in which this person is responsible. Our last entry left off with some fun statistics that outlined the enormity of cargo in which an average sized tow can transport. This statistic, supplied by the National Waterways Foundation, stated that an average sized, 15 barge tow can transport as much as 216 rail cars, and 1,050 semi-tractors!  Just one barge alone can carry 58,333 bushels of wheat, enough for 2.5 million loaves of bread!

Have you ever wondered how you can get a job running a tow boat up and down the Mississippi River?  Did you know that there is actually a shortage of river boat pilots? 

Recently Susan Pastor with the U.S. Environmental Protection Agency wrote an article in the Spring 2012 edition of the Fox River Current titled “Latest Technology Guides Hydraulic Dredge”.  The article was about the use of a Real Time Kinematic Global Positioning System (RTK-GPS) to aid the dredge operator in removing contaminated sediments from the Fox River in Green Bay, WI.  In the article she writes about the use of the system and how it improves the accuracy in which a dredge operator can remove targeted sediments to designated depths.  These operators can view their progress in real time using pricey, high accuracy equipment.
