An unmanned, autonomous, ocean-going vessel including a primary hull and a rigid wing rotationally coupled with the primary hull that freely rotates about a rotational axis. At least one of the primary hull and the rigid wing includes at least one selectively floodable compartment configured to selectively flood to submerge the primary hull and at least a portion of the rigid wing. The vessel further includes at least one controller configured to maintain a desired heading. The vessel further includes a control surface element configured to aerodynamically control a wing angle of the rigid wing based on a force exerted by wind on the control surface element. The vessel further includes a rudder. The at least one controller is further configured to determine a rudder position and generate a signal to position the rudder. The vessel further includes a keel coupled with the primary hull.

A distributed temperature system with at least one optical fiber is provided. Each optical fiber runs horizontally and vertically within at least one compartment of a ship. Each optical fiber connects to a distributed temperature system unit or is multiplexed to a single temperature system unit. The system employs Optical Time Domain Reflectometry to support measurements of optical pulses in processing bins defined along the fiber. The spatial fidelity of the measurement capability is sufficient to localize a fire detection in individual shipboard compartments. The system can diagnosis conflagration events that produce fire and also flooding in the compartment.

The present invention relates to a balance maintaining device for a transport apparatus. The balance maintaining device comprises a loading frame formed to be long in the lengthwise direction thereof and having two or more first and second supports, which are respectively formed at both sides of the lower portion of the loading frame, and a lower frame provided at the lower portion of the loading frame, and having both upper sides thereof linked and coupled to the first and second supports. The outside of the lower frame is coupled to a transport apparatus so as to maintain the loading frame in a horizontal state when the transport apparatus is shaken.

An offshore power generating system has a buoyancy body shaped as a hull with a bow and aft end, and elongated mast extending up from the buoyancy body to the buoyancy body about a horizontal transverse axis. A rotor is supported in one end of the longitudinal mast for rotation about a horizontal axis. The buoyancy body is kept in position with the bow turning up into wind and incoming waves. Rotational support of the mast has a horizontal rotational axis through the center of gravity of the mast that lies in the center plane of the buoyancy body above the aft end when the buoyancy body lies in operational position in calm sea with the rotational axis of the rotational support of the mast orthogonal to the center plane of the buoyancy body. A method for on-board loading and commissioning of mast with installed rotor on-board a buoyancy body.

A system for autonomous ocean data collection includes at least one sensor capable of collecting sensor data, at least one transmission device, and at least one computing device comprising one or more hardware processors and memory coupled to the one or more hardware processors, the memory storing one or more instructions which, when executed by the one or more hardware processors, cause the at least one computing device to generate data for transmission based on the sensor data collected by the at least one sensor, and cause the at least one transmission device to transmit the data.

A tugboat for assisting a marine vessel to maneuver. The tugboat boat comprises an engine driving one or more propulsors with a controllable direction of thrust, a towing line for establishing a pulling connection between an assisted vessel and the tugboat, a first sensor arrangement configured for sensing the size and direction of the pulling force that the towing line exerts on the tugboat, a second sensor arrangement configured for sensing the orientation of the tugboat, a controller in receipt of a signal from the first sensor arrangement and in receipt of a signal from the second sensor arrangement. The controller is informed of the size and direction of thrust generated by the one or more propulsors, and the controller is configured to determine if a safety threshold is exceeded on the basis of: sensed size and direction of thrust, sensed size and direction of the pulling force, and sensed orientation of the tugboat.
