A cover for a trench of a cable management system has a cover plate. The cover plate is configured in such a way that the cover plate fully covers the trench. The cover further has at least one spring assisted hinge fixed to the cover plate at one end of the cover plate. The at least one spring assisted hinge is configured in such a way that the cover can be attached to the trench by the at least one spring assisted hinge in an openable manner.

An energy transmission device for a watercraft includes a tower arranged on land, a telescoping boom connected to the tower for pivoting about a horizontal axis and about a vertical axis, said boom including a free end, and a first plug connected to the free end of the boom and designed to electrically contact for transmission of electrical energy a second upwardly oriented plug on the watercraft via a vertical plugging motion from above by pivoting the boom relative to the tower.

The invention relates to a mooring device for mooring a ship, the mooring device having a moored state, in which it engages the ship, and a non-moored state in which it does not engage the ship, the mooring device comprising a base, a movable arm, which is extendable and retractable, a connector carried by the arm for engaging e.g. a ship, a winch, a tensile element having a first end engaged by the winch and a second, opposite end fixed with respect to the second end of the arm and/or the connector, and a distance keeping system configured for keeping a minimum and non-zero distance between the base and the object engaged by the connector. According to the invention, the distance keeping system is integrated with the movable arm. The invention also concerns a mooring system comprising two such mooring devices.

A ground mounting assembly includes one or a plurality of posts, each attached to at least one stabilizing plate or scoop pyramid. The post may be driven into the ground and then lifted to deploy plates into a locking mechanism, or driven into the ground by a pile driver with plate held in place, released, and driven further and deployed into a locking mechanism, or driven into the ground and double pounded inside the post to drive reinforcing plate into slotted winglets, or driven, double pounded and rotated to extend the reinforcing plates horizontally from the pole or pile. The post also can used as a mooring in harbors, lakes, or at sea. A system based on a double pounder pile driven mono pole, optionally extendable in length, is also described.

A floating barrier float section, and a waterfront barrier system formed from a number of connected float sections. An elongated main flotation tube has radially outwardly extending fence posts with connecting members, such as nets, between them, forming multiple longitudinal net sections about the circumference of the flotation tube, at least one of the net sections extending upwardly and forming a barrier to vessel passage. A vessel strike tends to rotate the flotation tube about its longitudinal axis, absorbing the energy from the strike and rotating the flotation tube to bring another net section into position. An underwater ballast member and a stabilizer float member may be added for additional resistance to rotation.

A storage structure is configured to be buoyant or retained above a water line. The storage structure includes a frame having a back beam, a left beam attached to the back beam, a right beam attached to the back beam and a front beam attached to the left beam and the right beam to form a substantially rectangular configuration, wherein prior to a last of the beams being secured together an interior space accessible through an opening. The storage structure includes a bladder configured to be positioned through the interior space though the opening wherein the bladder is sized to be retained within the interior space whether the storage structure is above the water line or buoyant, the bladder including a vent, a fill port and a drain wherein an amount of water within the bladder is manipulated to provide ballast or buoyancy to the storage structure. The storage structure includes at least one floor panel secured to the frame over the bladder, side walls extending from a perimeter of the floor panel, wherein one side wall includes a door for ingress and egress to the storage structure. The storage structure includes a roof attached to the side walls.

A glow-in-the-dark piling cap is described herein that uses glow-in-the-dark materials on a dock piling cap to make pilings to which the cap is installed visible at night without the maintenance hassles of electrical-based lighting. The cap provides typical protection for the piling from the elements as well as lighting to aid boaters and users of the structure associated with the piling to see the piling at night. The glow-in-the-dark substance can be coated on the piling cap or mixed into the plastic, resin, or other material used to make the cap. The use of glow-in-the-dark materials eliminates any need for maintenance. Thus, the glow-in-the-dark piling cap provides protection for the piling, and maintenance-free lighting to alert boaters and users of the structure associated with the piling to nighttime hazards.
