Are Your Backups Ready?

 

Air Compressor pressure settings should be checked.

 

Most critical systems on a towboat have either a back-up or a parallel system.

 

The main engines are a good example of a parallel system.  Both engines are set up to operate independently.  Though they work together to push the tow, one engine could be down while the other is operational.  The tow could still move, though with limited speed and maneuverability.

 Generator on the FREEPORT

The generators are also an example of a parallel system.  Both operate independently and each can handle the full load.  The difference though is that they can only supply the load independently since they cannot be synchronized typically in a towboat type application.

 

We normally know the operational ability of these parallel units because they are manually started and shut down by the crew.

 

An example of a system that relies on a back-up is our compressed air system.  Compressed air is a convenient power source onboard that operates many functions:

  • Main engine throttle controls
  • Clutch engagement controls
  • Navigation - Boat's whistle
  • Main engine starting
  • Portable power....chipping guns, pump engine starting
  • Portable pumps 

The compressed air system is designed to have a lead compressor and a secondary or back-up compressor.  The lead compressor handles the normal day to day load.  The back-up compressor starts up automatically when the primary unit cannot keep up with the supply requirements such as days when your needle guns are in use.  It will also start up automatically if the primary compressor fails.

So how do we know that the secondary compressor is going to work when it is needed?

 

Step one is to identify the primary compressor.  If the system is operating properly, the primary compressor will start when the air pressure drops below a set point.  On our vessels, the set point is about 115 psi.  

 

While secured at a fleet or dock, open an air supply valve and bleed off pressure.  At some point the start-up differential will be reached and the primary compressor will start up.  Document the start-up pressure for the unit that kicks in.  Is it your port or stbd compressor?  At what pressure did that compressor start up?

 

Next determine at what pressure the back-up compressor starts up.  Open the air supply valve again to bleed off pressure until the secondary unit starts up.  Record that pressure.  In most cases it should be around 100 psi.

  air compressor gauge

What happens next if the pressure continues to fall?  At some set point, the air pressure alarm should go off.  Continue the test by bleeding off air and document the point where the air pressure alarm sounds.

 

Secure the valve bleeding off pressure and observe where each unit shuts down as the air pressure builds.  Make sure the air alarm has been reset on the alarm panel if outfitted that way.

 

Remember our boats may have pressure setting some what different than our example.  In those cases it is more important to observe that the units start in the proper sequence as described. 

 

How often to check?  We do not specify in the Higman Policy and Procedure manual but as a prudent mariner, I would check the system as described quarterly.

 

Charles Thornhill

 

 

Charles Emmitt Thornhill Jr. passed away on June 13th, 2011.  Charles worked at Higman since 1998.  He was one of Maryland Marine's first Tankerman.  Before coming ill, Charles last days at Higman were spent on the M/V Preston N Shuford.  You may have known him from his many days spent with Stevie Joe Elliott on the M/V Chesapeake and the M/V Decatur.  Many knew him as "Cat-eyed Charlie" or simply "Thorn".  Charles was a very dedicated and loyal employee and close friend to those that knew him.  He will be deeply missed by many.

 

 

Asian Carp come to the Canal 

 

Watch out for flying fish!

 

The crew of the M/V MARRERO had a surprise last week while nosing into the bank near Algiers Lock on the canal side.  Two good sized Asian (Silver) Carp jumped at least 5 feet and landed on the back deck.

Tankerman Ronnie Barnett shows off his catch!

Silver carp were imported to North America in the 1970s to control algae growth in aquaculture and municipal wastewater treatment facilities. They escaped from captivity soon after their importation and are considered a highly invasive species.

 

Silver carp together with the closely related bighead carp often reach extremely high population densities and are thought to have undesirable effects on the environment and on native species.

 

By 2003, silver carp had spread into the Mississippi, Illinois, Ohio, and Missouri rivers and many of their tributaries in the US. They are now abundant in the Mississippi River watershed from Louisiana to South Dakota and Illinois, and are close to invading the Great Lakes via the Chicago Sanitary Canal.  Navigation dams on the Mississippi River seem to have slowed their advance up the Mississippi River, and until late November 2008 silver carp had not been captured north of central Iowa on the Mississippi.  

 

The silver carp is also called the flying carp for its tendency to leap from the water when startled.  They can grow to over 40 lb, and can leap 10 ft in the air.  Many boaters traveling in uncovered high-speed watercraft have been injured by running into the fish while at speed.

 

Do we need an on deck PPE requirement for flying carp? 

Heat Stress 

 

Exposure to direct sunlight.

Exposure to direct sunlight can create a heat build-up on the barge's steel structure.

Summer is here!

 

Heat Stress is the potentially dangerous condition that occurs when the body is unable to regulate its core temperature. There are three main classes of heat stress disorders.

 

Heat cramps are painful and severe muscle spasms, primarily in the extremities and abdominal wall. Victims may experience profuse sweating, and dizziness. Treat by moving victim to a cool place and begin re-hydration process. Do not keep the victim sedentary in direct heat.

 

Heat exhaustion is peripheral vascular due to excessive water and salt depletion. It is caused by failure to replenish fluids lost in perspiration. Symptoms include sweaty and pale or flushed, cool, clammy skin; fatigue; nausea; headache and possible dizziness, nausea and/or vomiting. Heat exhaustion victims should be placed in a cool place; loosened clothes, applying cool compress, slowly reintroducing fluids and monitoring them for symptoms of shock. Seek advanced medical assistance immediately for further assessment and treatment.

 

HEAT STROKE IS A MEDICAL EMERGENCY THAT REQUIRES ADVANCED TREATMENT WITHOUT DELAY! It is the result of the collapse of the thermal regulatory mechanism; the ability for the body to cool itself. Body temperatures rise to critical levels of 104° F to 108° F. Symptoms include the stopping of sweating; hot, dry skin; red or molten skin; core body temp > 104° F; confusion; loss of consciousness; and convulsions. Treat by calling 911 emergency medical services, moving the victim to a cool area while waiting for transportation to hospital, using cool water to soak clothes and body, and fanning person. Do not give fluids if the victim is unconscious.

 

Preventative Measures for Heat Stress:

 

  • Drink moderate amounts of water frequently.....4 to 8 ounces of water every 15 minutes while working in hot humid conditions.
  • Wear sunscreen with an SPF level of 15 or higher recommended.
  • Hats should be worn for sun protection.

Drinks like Coke and Sprite are not a substitute for water.

Do not rely on electro replenishment fluids such as Gatorade® as a sole source of hydration.  Water is alway the best source for hydration.

Nautical Trivia

 

How Greenville, MS became known as the "Towboat Capital of the World".


Shortly after the end of the Civil War, the burgeoning railroad companies began buying up all the steamboat companies and shutting them down in an effort to eliminate competition in the transportation of bulk goods in America. The movement of large quantities of materials on the Mississippi and her tributary rivers came virtually to a standstill, as the railroad industry grew even larger and more powerful, politically and structurally. The huge and oftentimes very ornate steamboats ceased to travel the Mississippi, Arkansas, Tennessee, Ohio, Allegheny and Missouri rivers.

Greenville, Mississippi
As WWI came to an end, it was realized that the immense need to move bulk goods in large quantities during national emergencies could not be met by the railroad industry currently in existence. However, no private concerns were willing to take the risk and try to restart the river transportation business. The Mississippi River was a virtual wilderness area with shifting sandbars and flood and drought cycles changing the course and depth every year. The Inland Waterways Corporation was established by the Transportation Act of 1920 to build and own boats and barges in order to move cargo on the Mississippi River and its tributaries. Major General T.Q. Ashburn, head of the IWC, stated, "By 1890, common water carriage, as it formerly existed on the Mississippi River, had disappeared. It's revival began in 1920 and by 1926 more freight was transported upon the Mississippi River than ever before in history." From the Inland Waterways Corporation came the Federal Barge Line.
  
Following the Great Flood of 1927, and because the Mississippi and its tributaries drain 41 percent of the land mass of the continental United States, covering 31 states, Congress passed the most comprehensive flood control legislation ever. The Flood Control Act of 1928 authorized the Mississippi River and Tributaries Project, a major flood control and navigation act. The four major elements of the act were building and maintaining a levee system, building floodways for excess run-off, establishing channel improvements and stabilization and finally developing tributary basin improvements. This act effectively turned the responsibility of the Mississippi River over to the Corps of Engineers. It was on several Corps boats on the Lower Mississippi around Vicksburg that three young men were working during the Depression.
  
Having worked with his brothers and cousins on their grandfather's packet boat on the lower Yazoo and Sunflower rivers, eighteen year old Jesse Brent went to work for the Corps for two dollars a day. He soon worked his way up to pilot on a workboat. Percy Lemay was also a boat pilot and Gilder McCool was a dredge captain. When they decided to start a towing company, Gilder McCool's father, a cotton planter around Lake Washington, agreed to finance the young and energetic river men with a capital infusion of $3,000. In 1941, Greenville Towing Company was formed with the little wooden hulled boat named the Gilder Fay and a one-year contract to haul gasoline for the Goyer Company of Greenville. From that point on, the history of Mississippi River transportation was forever changed.
  
For the paltry sum of $800, a small boat was acquired and rebuilt. Greenville Towing began working for the Goyer Company hauling gas and diesel from Galveston, Texas to Greenville, Mississippi. There were no sleeping quarters on the boat and the crew slept in tents erected on the oil barge that belonged to Goyer. During construction of the boat, a credit application had to be filled out in order to finance the engines and reduction gears. The zealous salesman, realizing a problem with the collateral value for such a loan, added a zero to the value of the $800 hull making it $8,000 and the loan was approved. Years later, Captain Jesse Brent realized what had happened and declared, "If it had not been for that salesman anxious to make a sale, I don't know if I ever would have gotten into the towing business." In 1948, the steel hulled towboats Totty McCool and Ruth Brent were added to the fleet.

Boats and barges were built on the protected side of the levee and before completion were drug over the top and slipped into Lake Ferguson. It was during this time of expansion and trial and error that several of the original entrepreneurs branched out on their own to form competing companies. The Greenville towing concerns became well known for helping others join in the business by offering engineering and launching logistics to newcomers.  Anxious to go out on his own and provide a place for his two sons, Jesse Brent formed Brent Towing in 1956 with one of the original boats called the Betty Brent and two gasoline barges.  He had acquired a contract from Cities Service to deliver fuel from Lake Charles, Louisiana, to Vicksburg, Memphis and Nashville. Two box barges were added to make a four-unit tow. Jesse Brent's sons Lea and Howard grew up on the river and were both pilots. Lea went to Mississippi State to become a mechanical engineer and the firm began building its own boats and barges as the operation grew. Howard stayed on the river as a boat captain before coming ashore and into the office. In 1965, a major contract was signed with Mobil Oil to build an anhydrous ammonia barge and three all aluminum tank barges. The second Ruth Brent was built in 1966. The Mobil Oil deal was a long-term contract haul and the one contract that catapulted the Brent name into towboating history. At that time the firm owned seven barges and eight boats.
  
Over the next 15 years, several other Brent entities were formed to complement the towing company. Brent Marine Supply was incorporated to supply the rapidly expanding Brent fleet and to take advantage of better prices for parts and equipment. Brent Shipbuilding and Repair had several dry-docks on Lake Ferguson, refurbishing, rebuilding and repairing the Brent fleet and others. Superior Boat Works was acquired and brought into the Brent family of companies. By 1980, Brent Towing Company owned 60 tank barges and 24 towboats, becoming one of the largest privately owned towing companies on the Mississippi River. Jesse Brent died in 1982 at the age of 70. Howard and Lea Brent continued operating all companies until 1989 when they sold Brent Towing Company to Dixie Carriers.
  
Meanwhile, up and down Lake Ferguson, boats and barges were being built and new operations started to service the rapidly expanding inland waterways business. The east bank of Lake Ferguson, where the offices and shipyards of the growing towing industry were located, was known up and down the river as the Million Dollar Mile. At one time there were 35 towboat and barge companies operating out of Greenville. And in Washington D.C., Greenville, Mississippi, was known as the Towboat Capital of the World.

Once again I would like to stress the importance of preventing a Man Overboard situation.  We have discussed it many times and I am sure most of you are aware it causes more deaths in the inland industry than any other incident.  Man Overboard Prevention is very easy to practice.  It takes a few minutes to have a pre-task briefing to review the hazards you may encounter.  Discussing the consequences of a simple trip can help a crew member stay alert and keep him safe.

 

Have a great and very safe week!   

 

Sincerely,
