What Are Barge Boards?

Barges are not self-propelled and need to be towed by tugs or pushers. Its characteristics are simple equipment, shallow draft and large cargo capacity. Barges are generally non-motorized. They form a barge fleet with tugs or pushers. They can sail in narrow waterways and shallow waterways, and can be organized at any time according to cargo transportation requirements. It is suitable for cargo transportation between inland river ports. A few barges with additional propulsion devices are called motorized barges. Motor barges have a certain self-propelled capacity.

1. without power unit

Engineering ship specializing in the transportation of mud, sand, stone, various components, materials and mechanical equipment.

According to the performance and purpose of the barge, it is generally divided into:

Mud (stone) barge: It is equipped with a loading bay, which is opened and dumped.

Rock throwing boat: a barge. There are mechanisms and facilities for loading and unloading stones on the deck. According to its type, it can be divided into various types of rock throwing vessels such as roll type, flip type, tipping type and vibration type. The roll type and overturn type have been eliminated due to many defects in actual use due to the dump type of water tank filling roll and tipping. Dump type and vibration type are the main types used. Because of its single use and poor maneuverability in the country, it is replaced by motorized wooden boats.

Deck barge: square barge, semi-submersible self-propelled barge, jacket barge, etc. Square barges are widely used. Semi-submersible self-propelled barges and duct launch barges are new ship types that have emerged with the development of marine engineering. Barges with a deadweight of 30,000 tons have been manufactured. ^[1]

Large flat-bottom ships carrying passengers and goods on canals and rivers, without power propulsion devices, without self-propelled capacity, are driven by motor boats. Mainly used for passenger and cargo transportation. Barges can be singly or arranged in groups to be towed by tugs or pushed by pushers.

There are many types of barges.

There are two types of self-propelled and non-self-propelled barges, which are used to load the dredged sand with the bucket dredger, bucket dredger and grab dredger. Mud barge has open bottom type, open edge type and back cover type. There is a movable mud door on the bottom of the ship that opens the bottom mud barge. The open mud barge has movable mud doors on the stern of both sides. Opening the mud door can unload the mud by itself. Mud barge load is about 50 ~ 2000 tons.

A barge that specializes in silt. It is a supporting vessel for dredgers, and is generally non-self-propelled. The middle section of the hull is a mud tank, and the sides are air buoyancy tanks. According to the difference between the mud tank and the unloading method, there are: sealed bottom mud barge, no mud tank door, and mud dredging by the mud blower. Bottom mud barge is opened. There are one or two rows of square mud cabin doors on the bottom of the cabin. The mud barges are opened sideways, two rows of mud doors are opened at the lower part of the two sides, and a triangular air tank is arranged at the shaft part of the ship, which is suitable for dumping mud in shallow waters. The split mud barge is composed of two left and right symmetrical half hulls hinged at the fore and aft ends. Depending on the relative positions of the center of gravity and the floating center, the mud can be automatically unloaded around the longitudinal axis side. Self-propelled mud barges are mostly open-bottom type, with cargo ship types with high freeboard and high wind resistance, and barge types with ordinary mud barges and self-propelled power. Mud barges are classified by mud tank volume.
