GBT554-2008 Marine Bollard Type B

Introduction:

GBT554-2008 is a Chinese standard for marine bollards, which are used to secure ships or boats to a pier, wharf, or quay.

Type B marine bollards are designed for use with medium-sized ships or boats, and they typically have a cylindrical shape with a base plate that is bolted to the ground. The bollard is typically made of cast iron or cast steel, and it has a smooth surface to prevent damage to the mooring lines.

The standard specifies the dimensions, material, and load capacity requirements for Type B marine bollards. The load capacity varies depending on the size and configuration of the bollard, but it is typically in the range of 20 to 200 metric tons.

Type B marine bollards are commonly used in ports, marinas, and other marine facilities to provide a secure point of attachment for vessels. They are designed to withstand the forces of wind, waves, and currents, as well as the weight and movement of the vessel being moored.
