Fender Pier
A fender pier is a structure built or attached to protect another structure from damage, such as by ship collision. The structure in the river around the swing span A swing bridge (or swing span bridge) is a movable bridge that has as its primary structural support a vertical locating pin and support ring, usually at or near to its center of gravity, about which the swing span (turning span) can then pi ... is a fender pier. Types of fenders Many different types of fenders (also known as bumpers) can be used to prevent damage to piers and boats. Thick padded fenders Thick padded bumpers add are typically constructed from a high density foam and vinyl/polyester trilaminate however there are alternatives such as PVC or rubber. This type of bumper is utilized for its long life when attached to a pier though they can be expensive. Post/Piling fenders Post/Piling bumpers are attached to piers or docks that have been constructed with logs or cylindrical metal posts as the ...

Ship Collision
Ship collision is the structural impact between two ships or one ship and a floating or still object such as an iceberg. Ship collisions are of particular importance in marine accidents. Some reasons for the latter are: * The loss of human life. * The environmental impact of oil spills, especially where large tanker ships are involved. * Financial consequences to local communities close to the accident. * The financial consequences to shipowners, due to ship loss or penalties. * Damage to coastal or off-shore infrastructure, for example collision with bridges. As sea lanes are getting more congested and ship speeds higher, there is a good possibility that a ship may experience an important accident during her lifetime. Higher speeds may cause larger operational loads, like slamming, or excessively severe loads, for example during a collision. Denser sea routes increase the probability of an accident—in particular a collision—involving ships or ships and shore or offshore s ...

Swing Span
A swing bridge (or swing span bridge) is a movable bridge that has as its primary structural support a vertical locating pin and support ring, usually at or near to its center of gravity, about which the swing span (turning span) can then pivot horizontally as shown in the animated illustration to the right. Small swing bridges as found over canals may be pivoted only at one end, opening as would a gate, but require substantial underground structure to support the pivot. In its closed position, a swing bridge carrying a road or railway over a river or canal, for example, allows traffic to cross. When a water vessel needs to pass the bridge, road traffic is stopped (usually by traffic signals and barriers), and then motors rotate the bridge horizontally about its pivot point. The typical swing bridge will rotate approximately 90 degrees, or one-quarter turn; however, a bridge which intersects the navigation channel at an oblique angle may be built to rotate only 45 degrees, or ...
