An autonomous navigation type marine buoy includes: a buoy body consisting of a floating body; an internal sensor; a detection unit that receives a GPS signal and information of the internal sensor; an on-water exploration unit that explores a state on a sea; an underwater exploration unit that explores a state under the sea; a determination unit that creates a navigation plan for the buoy body; a propulsion unit that propels the buoy body; a navigation control unit that performs drive control of the propulsion unit so that the buoy body navigates according to the navigation plan; a power generation unit; a power storage unit; a communication unit that communicates with an outside; an emergency signal unit that receives a distress signal and specifies a transmission position of the distress signal; and an evacuation room that accommodates a victim, in which the autonomous navigation type marine buoy has an autonomous navigation mode of performing autonomous navigation to a set position on the sea, a home position mode of autonomously holding a home position at the set position on the sea, and a rescue mode of performing autonomous navigation to the transmission position of the distress signal on the sea when the distress signal is received.

The invention relates to a method and apparatus for testing a lifeboat sprinkler system without launching the lifeboat. A tank (5) of freshwater is arranged adjacent the lifeboat (1) on a marine vessel or oil platform (2). A line (24) is connected from the tank (5) to the sprinkler system of the lifeboat (1). The pressure of the water supply is arranged by means of the location of the tank (5) and/or a regulating valve (23) to mimic the pressure of the seawater that the system would access from an inlet (14) in the lifeboat hull (15) if it were launched.

A survival craft comprises a hull (10) formed from inflatable members (12, 13) and mounting a powered propulsion system (18, 19) for the survival craft. A superstructure (11) is mounted on the hull and formed from inflatable members (25, 26, 29a-29i) and a flexible roof (28) supported by the inflatable members (25, 26, 29a-29i). The superstructure provides the hull (10) with increased longitudinal rigidity that reduces the tendency of the hull (10) to bow longitudinally when the propulsion system (18, 19) is operating. The survival craft forms part of a marine escape system with the survival craft deflated and packed in a container including an inflation system for the survival craft. The system has a deployment system for amounting on a marine structure and carrying the container with the deployment system transferring the container from the structure to the water where the inflation system inflates the survival craft for access by persons.

A collapsible transom for an inflatable raft has a front section including two parallel front struts and a rear section including a floor portion and a collapsible support portion. The floor portion includes two parallel rear struts, and the two parallel front struts and two parallel rear struts are slidably connectable to each other by insertion into tubular end portions. The support portion is pivotally connected to the floor portion and movable between an expanded position with the support portion substantially parallel to and spaced away from the floor to a collapsed position with the support portion adjacent the floor.

A cruise system using mobility vehicles, may include a cruise ship having a cabin space used as a cabin when a mobility vehicle is aboard. A mobility vehicle is configured to board or disembark the cruise ship, and when aboard, park in the cabin space to serve as a cabin. A connector electrically connects the mobility vehicle and the cruise ship to enable power exchange or data communication between the mobility vehicle and the cruise ship.

A vessel includes a body, such as surfboard, that floats in water. One or more thrusters, and one or more sensors are provided on the body. A controller is configured to selectively activate the thrusters to cause the vessel to move along a path through the water, receive sensor data from the one or more sensors while the vessel is moving along the path, determine, based on the sensor data, whether a dangerous condition is present in the water; and output a warning when the dangerous condition is present in the water. For example, the collected sensor data may relate to locations and directions of currents in the water, the dangerous condition may relate to a rip current, and the warning may identify at least one attribute of the rip current. A map identifying a location of the dangerous condition may be generated and forwarded to other devices.
