River boats first appears in history around 3500 BC. Transportation in waterway made trade and growth of civilization possible. In post-colonial United States, Water Trasport especially made it possible for new country to grow and prosper. In reality, a cargo of deer and bear hides traveled down the Mississippi River in 1705, making it one of the first forms of transportation in America.
Next came the flat-bottomed boats that could be built by strapping planks, called “flat boats” or “keelboats”. In reality, these floats need a “push” when carry substantial loads. The “push” later knowns as “tow”, and the term “towboat” came to mean the power boat. Nowadays, towboats can be as long as 200’ in length and as wide as 50’ with flat bottoms varying from different rivers they navigate. There diesel engines can range from 600 to over 10,000 horsepower. According to the American Waterway Operators Association, there are 4 basic type of river barges currently under use on U.S. rivers: The open dry cargo barge transports coal, steel, sand, and lumber; the inland liquid cargo tank barge transports petroleum, fertilizer, and chemicals; the covered dry cargo barge transports grain, soybeans, coffee, and other items that need to be protected from the weather; last, the coastal barge that is used in coastal service for transport Petro byproduct and the fuel tank for NASA flights. Thes ocean-going barges are deeper for better stability in open ocean.
There are many benefits from barge utilization. To begin with, it is the safest transportation with few spills and few accidents. Barges produce little pollution and noise, with naturally established river routes. However, there is also downsides to barge, general speaking, barge traffic is slow. As we continue to be confronted by rising fuel prices, pollution, and congestion, the barge has become increasingly vital in comparison to truck, railways. During the summer of 2008, several shippers stated that if more mills could transport by water, they would acquire more commodities. The major trade off, of course would be the additional time spend in transit.
As a result, simply taking advantage of the fuel savings is insufficient to encourage people to use barges. As stated in the article, the barge line must be proactively in proving their competence to any shippers who could be interested in using their services.
Fuel Efficiency of barges
The news article published by The Maritime Executive indicates that inland river barge transportation has improved its efficiency for cargo to truck or railroad. According to the study, the barges can carry a ton of goods 647 miles on a single gallon of gasoline, up from a previous estimate of 616 miles. The continuous upgrade of the fleet, as well as the high utilization rates reached in the latter half of the study period, contributed to the improvement in barge transportation.
The study conducted by the Texas Transportation Institutes’ center for port and waterways at Texas A&M University addressed cargo capacity, congestion, emission, energy efficiency, safety impacts, and infrastructure impacts. In this study, the cargo capacity of barges, trucks, and trains was compared in this study. A standard 15-barge river tow has the same capacity as 1050 trucks and 216 rail carriages drawn by six locomotives.
The study also estimated that the amount of cargo currently transported on major rivers is equivalent to more than 49 million truck trips annually. In comparison to truck and railway incidents, the safety level increased after correcting for differences in cargo quantity moved by each mode. For each member of the public injured in a barge accident, nearly 80 people are injured in train accidents and 824 are injured in a truck accident. In addition to that, there are 79 people who died and nearly 22 people could die from truck and train accidents respectively for one barge-related death.
Last but not the least, in comparison to other modes of transportation, barges are more ecologically benign. The study found that barges had a very low incidence of spills of more than 1,000 gallons, resulting in lower carbon and nitrogen emissions in comparison to railways or trucks. Barge release 15.6 tons of carbon, but in the meantime railway or trunk can generate 21.2 tons and 154.2 tons of carbon emission respectively.
Different type of Barges
Before we get into the nitty gritty of Barges. It is critical to comprehend the meaning of the term “barge.” Barges are not self-contained boats or ships; they are usually towed or dragged behind larger ships. A barge has flat bottom to enhance its carrying capacity, thus more cargo can be transfer. What is unique to barges are that in most cases, barges are used in smaller water parts only, such as inland waterway, lake or rivers.
Prior to the Industrial Revolution in Europe, barges were a common mode of transit for transferring commodities between locations connected by minor water bodies. However, following the Industrial Revolution, barge demand fell significantly due to the widespread use of steam engines and railways. Another factor contributing to the demise of barges is their slow speed.
Despite this, barges are still used because of their large capacity, and they have become an important mode of water transportation.
- Barracks Barge – houseboat, mainly used for residential purpose and has very eye-catchy look
- Dry Bulk cargo barges – used to transport grains, sand, minerals like steel and coal.
- Barges carrying liquid cargo – used to hail and ferry dry cargo, useful in transporting petrochemicals and fertilizers
- Car-float Barges – rail cart attached to the barges were like portable rail sets ferried from one location to another
- Split Hopper Barges – used to carry dredged material as they are fitted with proper unloading tools.
- Other Barges – power barges, a moveable power plant; Royal Barges, occasional barges that serves as a platform for celebration of royal functions.
There are different sizes of barges that have different capacity
- Barges with size 180 feet, it can transport approximately up to 2000 metric tons of goods.
- Barges with size 230 feet (small-medium size barges) it can carry up to 4000 metric tons of cargo.
- Barges wit size 270 feet (medium barges) it can transport up to 6000 MT of cargo.
- Barges wit size 300 feet, it can transport large volumes, up to 8000 MT of cargo in a single run.
The use of barges has declined but not complete extinction, it can carry vast amount of goods with lower cost than other modes of transportation. They are available in various sizes with great capacity. In most cases, the capacity of the cargo to be ferried by barges can be changed adequately because in a single voyage, one or more barges can be towed and this can increase the time-effective as well as cost effective. Furthermore, for transit on calm water, either upstream or downstream, self-propelled barges can be adopted, which can push themselves and aid effective cargo transfer. Additionally, the design of a barge is carried out for a specific water and confined to serve that water area only. If that barges need to serve in other ware, then it can only be used after properly towed by another ship or tug boat. Finally, as previously said, the royal barges are owned by the monarchs of the United Kingdom and in most cases are only used to give a luxurious destination celebration of an occasion.
The difference between ship and barges:
- Definitions: a barge is the type of ship which has large flat-bottomed vessel generally used for transporting goods on inland waterway
- Route: ship can work in both inland or open ocean but the barges are typically seen in inland only
- Transport: ship serve as multipurpose; it can be used to carry both good and people. Barges are only used to carry cargo.
- Propelling: Ships have their own propel system, whereas barges are towed.
- Usage: As previously stated, barges are mostly used to transport goods and materials in waterways. Ship is a Muti-facility vessel can used for mutiple purposes, such as used for destination holidays and recreational works.
- Maneuvering: ships is relatively easier than the barge in maneuvering, because barges are tugged with a ship and it is difficult to manage a vehicle with a trailer than the vehicle alone.
With these difference and quality between ships and barges, it can be states that ship can any mode of water craft that can carry both people and material. Whereas barges can only transport goods and other materials. Barges is very important in water transport system, with so many different types of barges serve different functions, the problem of choice can be solved.
