Drop spud barges can also be used for transportation of general cargo or as work platforms. The operation of the spuds can be operated by a crane placed aboard the barge or by a spud-winch that may be installed.

Hopper barges are usually of double-hull construction, wherein the sides and bottom of the cargo hold are separated from the hull by void spaces. These barges are designed for efficient transport of commodities in bulk, such as grain, coal, sugar, ore, steel , aggregates, timber products and numerous other cargos. Hopper barges have a boxed, single raked, or double-raked hull configuration. The hoppers may be covered or open.

Covers provide protection of cargos from outside elements. Covers may be roll-top telescoping , or lift-off stacking type. These are deck barges with cargo bins and open hopper type barges, both having stabilizing bulkheads in the cargo compartment. These barges are used at oil well drilling sites to contain and transport any liquids and shale cuttings produced by the drilling operation that cannot be discharged overboard because of environmental considerations. This cargo is then disposed of by an approved processing company.

These barges are subject to rules and regulations promulgated and enforced by the U. Coast Guard, which publishes appropriate manuals for public guidance. These barges are equipped with two deck-level bin tanks that provide a total of four separate compartments. Containing on-board piping and pumping systems, these barges are capable of both the circulation and discharge of fluids at any remote facility.

While inland oil well drilling sites are the primary operational service location for these barges, land based storage facilities also benefit from the storage and transportation aspects they provide. Oceangoing barges transport cargo beyond the inland water boundaries of a country. Using ocean barges as an alternative to higher speed ocean freighters can offer many advantages. Unimproved or shallow draft ports often are only accessible by tug and barge.

High-volume loads, such as large-diameter pipe, and extremely heavy equipment , such as pre-fabricated oil-production facilities, are especially adapted to ocean barging. The hazards of navigation and the forces of nature require oceangoing barges to be of specialized design and heavy construction. This results in an increase in cost of building, outfitting, maintaining, and towing such vessels.

American flag ocean barges are built to the requirements of the U. Each barge is inspected and certified by authority of these agencies, and appropriate documents are issued to be carried on board at all times. The Coast Guard and ABS should be consulted for complete information on their requirements on ocean barges. Coast Guard been notified and are there other government agencies that should be contacted? Volume 37 Issue 6. Volume 37 Issue 5. Everything is constructed on the assumption that iron and steel boats are the norm.

You will hit bottom from time to time, typically with any chines you might have below the water line grinding on the rock 'rip rap' that lines the canal edges, as you move over to allow several hundred tons of commercial barge to zip past. Despite a 'no wake' rule, you will have to be able to survive being thrown against underwater obstacles by these boats' hefty wash.

Nursing a fibreglass or wooden yacht through the canals can be a stressful activity. Inflatable fenders don't last very long and using old tyres is discouraged as they can be ripped off their lines or dropped and then they sink and block the lock gate mechanisms.

But by knowing you are at least as tough as what's around you, by having a well protected prop with good access so you can remove the inevitable shopping trolley from it and by having large bomb proof mooring bits, are some of the best ways of relaxing and hence being able to enjoy some of the world's best cruising waters.

Crag Cay , Mar 19, Barge Hull construction Crag has a point about the need for toughness in a hull that is intended for UK canals: however, even the first narrow boats were made of wood.

I also believe that the "barge" design desire for full time liveability and travel is somewhat like the Dutch barges and similar variations rather than a narrow boat.

The basic criteria is large volume and low, economical power as well as moderate to low construction costs. Greenseas2 , Mar 19, The 90 degree chines could shaped at 45 degrees from a shallow 6 degree V hull bottom. Extra layers of marine ply could be added to critical areas with heavy glass cloth laminated over.

I believe GRP weighs about lbs per cubic foot. Aluminium weight lbs per cubic foot. Thus, if you build a composite vessel to the same strength and stiffness as GRP or Ally, then it will weigh much less. If you build all three types of boat, to the same weight.
