A barrier for protecting a port, waterway, or off-shore structure is provided. The barrier has a front elongated pontoon which extends substantially the length of the barrier. A net assembly, provided either in sections, or as an elongated net, extends vertically upward from the front elongated pontoon and along the length of the front elongated pontoon. The net assembly is affixed to the front elongated pontoon with one or more net support beams. The front elongated pontoon is supported by a rear pontoon support structure, which may be a series of pontoons, each connected to the front elongated pontoon and spaced apart the length of the front elongated pontoon, or an elongated cylindrically shaped rear pontoon which extends substantially the length of the barrier. In some embodiments, a rear net section is attached to the rear pontoon support structure. In another embodiment of the invention, a barrier system for protecting a port, waterway, or off-shore structure is provided. The barrier system comprises two or more contiguous barrier units, one of which is a barrier according to the present invention that form a perimeter to protect the port, waterway, or off-shore structure and can additionally act as a debris barrier. In one embodiment, the barrier system forms a perimeter protecting a port or waterway. In another embodiment, the barrier system protects an off-shore structure.

A system is provided for automatic operation and status indication of a marine barrier gate. Embodiments include a system having a buoyant barrier gate that is movable between a closed position and an open position. An actuator moves the gate between the open and closed positions, and a sensor is operably connected to the actuator to generate data relating to a position of the barrier gate between the open and closed positions. A processor receives the data from the sensor and processes the data to move the gate between the open and closed positions, and detect the position of the gate. A human-machine interface is operably connected to the processor for communicating the detected position of the barrier gate to a user.

A set of components that can be used to construct a structurally sound dock are disclosed. The components can be extruded and the components are shaped such that interconnected components provide support for the other components thereby alleviating weak points due to welded only joints. A fascia channel provides additional strength by including structures that improve the vertical and horizontal strength of the fascia channel. HDPE plastic inserts and sheaves provide sound dampening for metal to metal contact points. Other components include a corner connector, a post system and a hinge system. The focus of this disclosure is the corner connector.

A marine barrier includes a flexible plate, a plurality of studs mounted on the flexible plate, and a plurality of buoyancy members attached below the flexible plate. The plurality of buoyancy members provides buoyancy for the flexible plate, allowing the plurality of studs above a water surface, while the plurality of buoyancy members below the water surface.

The cover delivery device (e.g., for use in selectably covering a watercraft) can include a first mobile support assembly, a second mobile support assembly, a drive shaft, and a cover carrier mechanism. The first mobile support assembly is mounted to and configured for movement along a first rail. The second mobile support assembly is mounted to and configured for movement along a second rail, which is generally parallel to the first rail. The drive shaft extends between and is rotatably mounted to the first mobile support assembly and the second mobile support assembly. The cover carrier mechanism extends between and is rotatably mounted to the first mobile support assembly and the second mobile support assembly. The cover carrier mechanism is configured for selectably deploying a cover carried thereby, with the cover carrier mechanism being configured to respectively roll and unroll the cover relative thereto.

A dock building apparatus comprises a cantilever arm (11) having a first portion configured to be supported on a ground area and a second portion for overhanging a construction area. The cantilever arm (11) is displaceable perpendicularly to the length of the cantilever arm. The apparatus further includes a lifting device (19) movable along the cantilever arm for bringing construction materials including foundation members from the ground area to the second portion of the cantilever arm, and a foundation building tool (15) movable along the cantilever arm for installing the foundation members in the construction area.
