The followings are some basic instructions of the regular inspection of foam filled fenders. 1. Inspect condition of the fender-to-pier connection hardware. Check for operability and signs of corrosion. Check to ensure that the fender is constrained horizontally so that it contacts the bearing surface for its full length. Ensure that the fender is free.. read more →
Component Tests of Cone Fenders and Cylindrical Fenders 1. Cone – Shaped Fenders / Energy Absorber For the axial compression simulation of the rubber cone type fenders, two rigid plates were used to sandwich the cone. The rubber cone had constant stress solid hexahedral elements. Since the cone had an irregular shape and thick walls,.. read more →
Marine fenders are used in the harbor facilities as cushion to absorb in berthing and play a role in making harbor facilities safe. The “Guidelines for The Design of Fender Systems: 2002(hereinafter guidelines)” published by the International Navigation Association Congress (hereinafter PIANC) describes the importance of temperature and velocity factors for designing marine fenders in.. read more →
Why Do Tugs Need Fenders? Tug fenders perform multiple roles, all of which need to be properly addressed in the specifications, ideally from an operational, performance and material perspective. Fenders Absorb Impacts When a tug contacts a ship this is a controlled collision and the kinetic energy can only be absorbed in one of three.. read more →
Maintenance of Marine Fenders Marine fenders are used between marine vessels and docking structures to prevent damage during berthing. They are also used to protect ships during cargo transfers at sea. Marine fenders differ in terms of size, shape, buoyancy, energy absorption, and materials of construction. There are five basic types of marine fenders. Three,.. read more →
Design of Fenders for Container Vessels Fender Spacing and Layout: Fendering system should be designed to spread the berth loads evenly along as much of the vessel side as is possible. Many vessels have considerable amounts of topside flare forward and aft, below main deck level. In the bow the amount of curvature in the.. read more →
Fenders used in STS transfer operations are divided into two categories: • Primary fenders, which are positioned along the parallel body of the ship to afford the maximum protection while alongside. They are also designed to absorb energy as the vessels berth alongside. • Secondary fenders which are used to protect the bow and stern.. read more →
Principles of Good Mooring Until the advent of bulk transport of goods and raw materials by sea, the basic requirements of a mooring system were to prevent the vessel from drifting away from a berth or from colliding with adjacent moored vessels. The system had also to allow for assisting in heaving the ship up.. read more →
Advantages and Disadvantages of Fender Types Fenders using elastomeric units 1. Hollow cylindrical (diametrically loaded) fenders a) Advantages: 1) economical; 2) easy to install or replace individual units; 3) may be mounted to give cover over a large vertical range. b) Disadvantages: 1) susceptible to damage by surging motion of vessel; 2) long length necessary.. read more →
