A subsea load monitoring apparatus having: a load sensor having a first end and a second end; a central processing unit configured for processing measurements from the load sensor; a battery for powering the central processing unit; an activation device being configured for activating the central processing unit from an idle operational mode to an active operational mode; a first and a second load attachment means connected to the first and second end of the load sensor, respectively; and an output device for the processed measurements from the load sensor. A subsea load monitoring system and methods for use of the subsea load monitoring system.

A tiller, a waterside thruster, a watercraft, a control method, and a storage medium are provided. The tiller includes a base member, a control portion, and a pressure sensor. The base member is connected to a body of the waterside thruster. The control portion is movably connected to the base member for receiving a control input and generating displacement with respect to the base member. The pressure sensor is provided between the base member and the control portion for acquiring a deformation pressure value caused by the displacement of the control portion with respect to the base member. The pressure sensor is triggered to generate a triggered signal when the deformation pressure value conforms to a preset threshold value of the triggered pressure. The triggered signal is configured to instruct that the waterside thruster performs a preset action.

A computer system has processing circuitry to control a force feedback unit to progressively increase a force feedback applied to the input device in response to a manual maneuvering of the input device towards a virtual stop position being defined in between an equilibrium position and a mechanical end position of the input device. The virtual stop position is a software-defined set point acting as an intermediate trigger for the input device. The force feedback is progressively increased until it reaches a maximum force feedback at the virtual stop position; and control the force feedback unit to reduce the force feedback applied to the input device at the virtual stop position in response to a force of a manual maneuvering of the input device exceeding the maximum force feedback value.

A method for a collision avoidance system of a host marine vessel, and to updating vessel classifications and navigational statuses of marine vessels.

A method for providing an electronic lookout function for an ego vessel is described. The method comprises receiving first low-effective-resolution image data from a first camera arrangement of the ego vessel, receiving first high-effective-resolution image data from a second camera arrangement of the ego vessel, checking whether there is any object on the water surface within the circular sectors depending on the low- and high-effective-resolution image data, and generating and outputting an object presence signal when an object is detected on the water surface within the circular sectors.
