Abstract: Fender for protecting an object from damage comprising a core of at least a closed cell foam part, an intermediate layer fully enclosing the core comprising at least a fiber reinforced cloth, a coating that at least partly covers the intermediate layer. The invention also relates to a fixed or floating maritime structure provided with such a fender and to a method for manufacturing such a fender.

Abstract: A system is disclosed for protecting supporting structures, such as those of a bridge or other such marine supporting structure, from the force of an impact of a vehicle/vessel. Such a system includes a plurality of modular components arranged in series and configured to dissipate the energy of the force through the progressive buckling of one or more of the modular components. Each modular component contains an energy dissipation unit that includes a plurality of adjacent cells. The energy of the force is dissipated in the buckling of the walls of the cells of the energy dissipation units through the formation of one or more plastic hinges and/or volume reduction of the cells.

Abstract: An anti-collision device made of a buffering energy-absorbing type web-enhanced composite material, including an anti-collision unit. The anti-collision unit includes a housing and a filling material body located in the housing, and the housing is a solid housing formed of a composite material surface layer or a sandwiched housing formed of a composite material surface layer internally filled with a sandwiched material, and the sandwiched material; the filling material body includes a space lattice body and an energy consuming material, the space lattice body is formed of fiber webs arranged in the housing in a single-layered unidirectional, single-layered bidirectional, multi-layered unidirectional or multi-layered multi-directional manner, and the energy consuming material is located between the fiber webs and/or between the fiber webs and inner walls of the housing.

Abstract: A frame rail assembly for a boat dock structure includes a first frame rail member, a second frame rail member and a corner bumper member. The first frame rail member is secured to a first side of the boat dock structure and includes a first channel and a second channel The second frame rail member is secured to a second side of the boat dock structure and includes a first channel and a second channel. The corner bumper is positioned at a corner between a first end of the first frame rail member and a first end of the second frame rail member. The corner bumper member includes a first section and a second section. The first section includes coupling members engaged with the channels of the first frame rail member, and the second section includes coupling members engaged with the channels of the second frame rail member.

Abstract: A grading rake having a handle and a rake head, and having stiff but bendable, flexible polymer tines in the rake head, with the tines angled back toward the handle, and with the end of the tines truncated and parallel to the plane of the handle and rake head.

Abstract: A fender having a compact spring shape for protecting an object, such as a dock or boat, includes a mounting portion connected to a resilient leaf spring portion. The leaf spring portion is designed to collapse and absorb a substantial amount of energy upon impact with another object while a free end of the leaf spring slides along a front side of the mounting portion. In a preferred embodiment, the leaf spring portion is extruded of a high-strength abrasion-resistant plastic material having a low coefficient of friction, such as ultra high molecular weight polyethylene (UHMWPE). The leaf spring portion may include multiple access holes sized admit a tool for installing or removing the fender.

Abstract: A lock and dam system for a waterway includes a dam extending across the waterway, a channel having a first entry-exit opening on a first side of the dam and a second entry-exit opening on a second side of the dam. The channel includes a lock. The system further includes a fascia proximate first entry-exit opening in the channel, and a fender system to protect the fascia from impact. The fender system includes a plurality of resilient flexible support element, a first panel supported by a first one of the plurality of support elements in front of the fascia and a second panel supported by a second one of the plurality of support elements in front of the fascia. The first and second panels overlap in a first direction parallel to the fascia and a second direction perpendicular to the fascia. In one exemplary embodiment, the first panel has a first shoulder and the second panel has a first step facing and overlapping the first shoulder.

Abstract: The lock and dam system for waterway includes a dam extending across the waterway, the channel having a first entry-exit opening on a first side of the dam and a second entry-exit opening on the second side of the dam. The channel includes a lock. The system further includes a fascia approximate first entry-exit opening in the channel, and a fender system to protect the fascia from impact with objects generally moving in a first direction. The system includes a first panel, a second panel, a first support element coupled to one of the first and second panels and coupled to the at least one fascia and a second support element coupled to one of the first and second panels and coupled to the at least one fascia. The first support element extends oblique to said one of the first and second support panels with the second support element extends oblique to said one of the first and second panel.
