A water area may be sheltered by installing, at an active boundary of the water area, a plurality of shields mounted on posts, each shield having a lower edge immersed in the water. Each shield may dissipate at least a portion of wave energy approaching the active boundary of the water area. One or more piers may be positioned within the sheltered water area or basin.

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 self-adjusting, drive-on, floating dock for personal watercraft including a central float having a plurality of central float rollers to support the keel or bottom of the hull of a personal watercraft; and a plurality of side floats with attached side float arms having attached side float rollers that support the sides of the hull of a personal watercraft; and in which at least one of the side floats is attached to the central float in such a manner to allow it to float independently of the center float, but is restrained from drifting away from said central float; and the independent buoyant forces created by both the central float and the plurality of side floats together support the hull of a personal watercraft.

Disclosed is a transfer system and method that enables the use of the port area and the elimination of the negative effects of traffic in the city, by making the landing or boarding operations of cruise ships underground in the cruise ports.

A kit for installing a boat dock to an underlying bed of a body of water includes a deck frame for supporting a deck surface and guide members configured to slideably engage a support pillar to the deck frame; dock flotation members for floating the deck frame on the body of water; and pillars configured to be engaged to the deck frame by the guide member and to be anchored to the bed to secure the deck frame to the bed. A deck panel consists of an external frame with a reinforced concrete panel within the frame and a method for assembling and installing a dock, supporting a deck frame on or above a body of water; inserting pillars through guide members on the frame to contact the underlying lake bed; and anchoring the pillars to the underlying bed.

A port monitoring system including: a port environment detection unit in which it is important to monitor the accurate position and posture of ships, especially large ships, in a port (or harbor), and which monitors the position and status of fenders in the port, and measures the environmental conditions of the port and thus generates port environment information to integrally manage ships and fenders in order to efficiently manage the port; a ship monitoring unit which is included in a ship and generates ship information of the ship; a fender monitoring unit which is included in a fender and generates fender information of the fender; a network; and a port management unit.

A marine cargo loader and handrail device includes a base plate, a post and a platform that is pivotally mounted to the post to allow the platform to move upward and downward. The platform can have two positions, the stored and deployed positions. When stored, the platform is in an upright position. When deployed, the platform is in a substantially horizontal plane with respect to the post. The device may also include a gas dampener to allow for a smooth descent from the stored position downward to the deployed position.

In summary, described herein is a mooring device for mooring a first structure to a second structure, the device comprising: an engagement member for releasably engaging the first structure; a dampener having a first portion movably connected to a second portion, the first portion being connected to the engagement member and the second portion being connected to the second structure, wherein the dampener is configured to damp load transfer between the first and second portions of the dampener and thereby damp relative motion between the first and second structures.
