Barge Service

Barge is designed to carry freight such as Project cargo, ODC, Containers, Heavy Machinery, finished steel or its ingredients, grain, sand or gravel, or similar materials. Barges covers are fabricated of fiberglass or steel. They can be lifted or rolled away for access to the barge hold, or cargo box.

Dry bulk cargo barges are typically operated and maintained with efficiency and environmental stewardship in mind. Typically, an informal set of industry best practices are applicable, including:

Barge loading

Barge loading should be conducted in a manner that minimizes the amount of cargo spilled onto the deck. The loading process is the responsibility of the loader operator at the loading facility.

Barge unloading

Barge unloading should be conducted in a manner that minimizes the amount of cargo spilled onto the deck. The unloading process is the responsibility of the unloader operator at the unloading facility. Unloading can be done with a Grab Bucket Barge Unloader or a Continuous Barge Unloader (CBU). The Grab Bucket system employs a clamshell bucket suspended by a set of hoisting cables, with a separate set of control cables that open and close the bucket. The CBU is a series of buckets supported between two strands of roller chain, running in a continuous loop.

Cargo spillage

The nature of the dry bulk commodity business is such that some amount of cargo spillage is typically unavoidable. In such cases the following practices are standard:

When possible, cargo residue will be swept and shoveled back into the hopper, provided cargo is the same.

If the current cargo is not the same as the residue remaining on the barge deck, the residue should be swept up against the barge coaming and in some cases may be shoveled and placed into a container or bag.

If the quantity of cargo exceeds an amount that can be safely cleaned, then a barge report will be filed and the cargo will be cleaned at a facility.

Trash on deck

Trash that may be left on deck such as junk line or garbage is bagged and placed so that exposure to rain or the possibility of being washed off of tow is eliminated.

Below deck water

Barge hulls are maintained to minimize the accumulation of river water below deck.

If a barge develops a detectable leak, crew members will go below deck and install a temporary patch, known as a shingle.

The hull will be repaired when possible.

Water that accumulates in void tank generally needs to be removed. When this is the case, the following best practices are applicable:

Visually inspect the water in the void for a sheen.

If no sheen is detected, the water is pumped from the void tank into the river. The crew will observe the water surrounding the tow for any sign of a visible sheen.

In the event a visible sheen is detected, the pump is immediately turned off (provided the barge is in no danger of sinking.) and the corrective action process as described in the VGP is implemented.

Barge inspection

When a barge is picked up by a boat, the on watch deck crew does an inspection of each barge that includes the following:

Each void tank is inspected for water. If water is found it is visually inspected for a sheen.

The deck of each barge is visually inspected for cargo spillage or trash.

Barge inspections are recorded on a barge inspection form.

It is common for a barge to be handled by multiple vessels and even multiple vessels each barge voyage (empty to empty).

Barge inspection forms are maintained shore side.

At least once every watch, the deck crew inspects the void tanks of each barge to ensure that no water is being taken on.

Deck scaling

Barge decks are maintained to minimize the formation of large rust scales, this is typically accomplished by painting the deck as needed.

Terminology related to the dry bulk cargo barge industry:

Above Waterline- The portion of a barge that is out of the water at a given time. This will vary based on whether or not the barge is loaded or empty.

Barge- Non-powered cargo or work vessel.

Barge Pump- Small portable pump used for removing water.

Barge Voyage- The time from which an empty barge is placed in tow, until it has been loaded, emptied and returned to a fleet. May include stops in a terminal fleet, cleaning and/or repair.

Barge Washing- Using water to clean cargo from the deck and/or hopper of a barge. Typically conducted at a barge washing facility.

Below Waterline- The portion of a barge that is below the water at a given time. This will vary based on whether or not the barge is loaded or empty

Boot- Fitting attached to the end of a suction hose on a barge pump that prevents large particles from being suctioned.

Cargo Box- Open hold on a barge for cargo

Cargo Residue- A quantity of product remaining on a barge deck on in a hopper.

Cargo Trimming- Shifting or rearranging cargo to level a barge.

Coaming- High sides around an open hopper barge.

Cover- Fits over the coaming. Used to protect weather sensitive cargo such as grain. Large, typically constructed of steel or fiberglass. Depending on style, they can be lifted off by crane or rolled away for access to the hopper.

Cover Hatch- Lid which allows access to the cargo hopper through the cover. Typically used for cargo loading.

Deck- The work area and walkways of a barge.

Dry Dock- Structure used to raise a vessel out of the water so as to expose all parts of the hull for inspection, repairs or painting.
