A method for operating a towing winch and an electric drive for a towing winch, the towing winch including a rotatable winch drum for spooling a spoolable medium, and an electric motor operably coupled to the winch drum to rotate the winch drum, wherein the electric drive is configured to be operably coupled to the electric motor, and configured to control, during a towing of at least one object connected to the spoolable medium, a tension of the spoolable medium between the winch drum and the at least one object to be towed to be equal to or lower than a tension limit value; and monitor, during the towing, a roll angle of the tug, and in response to the monitored roll angle of the tug being outside of a predetermined range, lower the tension limit value providing roll compensation.

Automatic release system on a supply- or tug-vessel, comprising a rotational towing hook (10) supported on a vertical axel (16), for receipt of a towing hawser (12), and a releasing unit for releasing the towing hawser (12) from the towing hook (10). A registration unit (14) is installed above the towing hook (10) working area, said registration unit (14) being a tiltable or liftable hoop plate, where the registration unit (14), under influence of vertical angular movement in the towing hawser's (12) horizontal direction in relation to the towing hook (10), is arranged to trigger release of the releasing unit.

Communication network architectures, systems and methods for supporting and/or effectively utilizing a network of mobile and/or static nodes. As a non-limiting example, various aspects of this disclosure provide communication network architectures, systems, and methods for supporting a dynamically configurable communication network comprising a complex array of both static and moving communication nodes (e.g., the Internet of moving things, autonomous vehicle networks, etc.). For example, a communication network, or one or more nodes thereof, implemented in accordance with various aspects of the present disclosure provide for efficient operation of distribution centers (e.g., ports, rail hubs, air freight hubs, etc.) that include networks of moving things. For example, in an example implementation, various aspects of the present disclosure provide systems and methods for efficiently controlling the operation of vehicles (e.g., boats, tugboats, ships, trucks, etc.) involved in port operations.
