An emergency ship arrest system includes a vessel attachment system, a retrieving system, and an anchor system. The vessel attachment system is configured to connect to a vessel at sea, and includes a bridle system and a hawser line. The bridle system is operatively connected to the hawser line's proximal end. The bridle system is configured to engage at least four fittings on a foredeck of the vessel to distribute the load over the foredeck. The retrieving system includes a retrieving line with a proximal end that is detachably connected to the hawser line's distal end in a setup position. The anchor system includes a main rode and a para sea anchor. The main rode's proximal end is detachably connected to the hawser line's distal end in an anchor position.

A sea vessel (1), such as a tugboat or a fishing vessel, including a hydraulic winch (10) connected to a hydraulic system (100), and at least one main engine with a main engine crankshaft (22) connected to a propeller or a thruster. The hydraulic system (100) comprising: a first, hydraulically powered genset (106) including a hydraulic motor and a generator, at least one hydraulic pump (105) connected to said crankshaft (22). The hydraulic pump (105) is configured for driving said first genset (106) to generate electricity, and the hydraulic pump (105) is configured for driving said hydraulic winch (10), and first valve element (102) are used for selectively directing hydraulic fluid to the hydraulic winch (10) or to said first genset (106) of said hydraulic system.

The Earth's oceans naturally distribute items aboard barges or other carrying vessels in an efficient manner. Carrying vessels are inserted into gyres, currents, eddies or other sources of flow by support vessels, which may be manned or autonomous. A carrying vessel may be transported from a port or other origin to a point within a naturally occurring flow of seawater by a support vessel, and permitted to travel at speeds and in directions defined by natural factors, from one point to another point, for extended durations. A carrying vessel may be removed from a naturally occurring flow of seawater by a support vessel and transported to a port or other destination. Flow rates, transit times and points within naturally occurring flows at which a carrying vessel may engage with or disengage from a support vessel may be determined according to a machine learning model or in any other manner.

A method for controlling a towing train including a ship and at least one tug acting on the ship, including the steps of: providing a data model, which includes fixed data of the ship and of the at least one tug as well as variable environmental data; determining the current course, the thrust vector, and the inertial force of the ship and specifying a desired travel direction of the ship with subsequent calculation of the correction force vector and correction torque required to achieve the desired travel direction; calculating the required positions, orientations, and drive settings of the at least one acting tug using an algorithm that accesses the data model and generating control commands for the at least one tug such that the sum of all the force vectors and torques of the at least one acting tug corresponds to the required correction force vector and correction torque; transmitting the generated control commands to at least one acting tug and monitoring the completion of the control commands; and conducting an evaluation of the produced correction force vector and correction torque after completion of the control commands and generating and storing correction values in the data model when deviations are detected between the produced correction force vector and the required correction force vector and/or between the produced correction torque and the required correction torque and then repeating certain steps.

A tug (11) comprising a deck having an aft deck (16), a central deck (12) and a forward deck (15) and a rotatable towing installation (13) disposed on the central deck. The towing installation and central deck are sloping upwards from the aft deck to the forward deck with respect to a horizontal plane. The upward sloping angle (α) of the towing installation is at least 5 degrees. The design provides free towing all around in the horizontal plane in combination with sufficient bow height and buoyancy and in addition below deck space for e.g. additional accommodation.
