An exemplary sensor device provides marine vessel data of a marine vessel without integration to the marine vessel's information systems. The sensor device includes a receiver configured to receive at least position and time information relating to the marine vessel. At least one sensor is configured to measure marine vessel performance data. The at least one sensor can measure the marine vessel performance data when the sensor device is affixed to the hull structure of the marine vessel. At least one processor is configured to perform frequency analysis of the measured marine vessel performance data and to generate marine vessel data based on the received at least position and time information and the frequency analyzed marine vessel performance data.

A sealing arrangement is used when mounting a thruster in a well box attached to a hull of a marine vessel. The well box has an axis, a bottom flange, a top flange, an annular wall therebetween and hoisting pipes fastened parallel with the axis to the bottom flange radially outside the annular wall. Both the well box and a mounting flange have at least one surface acting as a sealing surface between the well box and the thruster. At least one of the surfaces has a groove for a seal for preventing water from entering the well box. The well box has a rotationally symmetric wall with an internal guide surface and the mounting flange of the thruster has an axially extending rotationally symmetric part provided with an outer surface having means for sealing the mounting flange in relation to the well box.

A threaded connection body is welded to the wall of a pipe, seachest or other flooded cavity within the hull of a ship or floating offshore installation. A sealed cutting apparatus is mounted via a valve unit n the connection body and a cutter extended through the open valve to form an opening in the wall. After retracting the cutter and closing the valve, the cutting apparatus is replaced by an inspection unit having a camera which is extended through the valve and the opening to inspect the cavity. After retracting the camera and closing the valve, the inspection unit is replaced by a plug deployment unit which advances a plug through the valve and screws it into the connection body. The valve unit can then be removed and replaced with a cap so that the plug and the cap provide a double seal to the connection body.

The present disclosure relates to pontoon shields. The pontoon shields disclosed herein may, for example, protect pontoons from damage and/or enhance the aesthetic appearance of pontoons. The shields may be fashioned from one or more segments of resilient material configured to attach along a longitudinal aspect of a pontoon. The shields may be fashioned from a single segment, or from one or more segments configured to mate with one another. The shields may be attached to a pontoon, for example, via an adhesive, weld, and/or one or more brackets, or other mechanical means.

A floating VAWT comprising a wind turbine body having a lower body portion and an upper body portion; at least one blade attached to the upper body portion for converting wind energy to rotation of the wind turbine body; and an energy converter attached to the wind turbine body for converting the rotation of the wind turbine body to electrical energy. The energy converter comprises a first energy converter part, and a second energy converter part to be kept relatively stationary in relation to the first energy converter part. The energy converter is attached to the wind turbine body by means of a first releasable mechanical coupling between the first energy converter part and the lower body portion of the wind turbine body, and a second releasable mechanical coupling between the first energy converter part and the upper body portion of the wind turbine body.

Disclosed is an apparatus that is able to generate an image to deter a shark from attacking a watercraft (e.g. a surf-craft). Also disclosed are methods of manufacturing and retrofitting watercraft to include the apparatus that is able to generate an image to deter a shark from attacking the watercraft.

A monitor device includes a memory, a hardware mount configured to attach to a rigging member, a motion sensor configured to detect a first motion characteristic of the rigging member, and a processor operatively coupled to the memory and to the motion sensor. The processor is configured to receive the first motion characteristic from the motion sensor. The processor is further configured to send the first motion characteristic to a controller. The controller is configured to receive a second motion characteristic generate an output for a display based on the first motion characteristic and the second motion characteristic.

The present invention relates to a ship data consolidated management method and a device for same. Accordingly, the present invention relates to a ship data consolidated management method and device, the method being characterized by comprising the steps of: collecting ship data from at least one piece of ship equipment; converting the ship data to a certain data format; and transmitting the converted ship data to an external device.

Disclosed herein is a marine vessel, which in one example comprises a substantially continuous deck. Also disclosed is an example with a plurality of parallel longitudinally aligned channels extending from the forward deck to the aft deck. The vessel having a vessel cabin resting on and longitudinally movable upon the deck. The vessel cabin in one example having a plurality of rolling wheels attached thereto; wherein the rolling wheels roll upon the deck and allow longitudinal movement of the vessel cabin between the aft region and the forward region. A drive unit (motor) may be provided. The drive unit optionally mounted to the cabin and in one example having a drive wheel mounted to the drive unit and configured to rotate the drive wheel. The drive wheel(s) contacting the deck such that rotation of the drive wheel repositions the cabin between the aft region and the forward region.

A method for calculating the surface vector of at least one vessel progressing under engine at cruising speed. When the vessel is in a defined position, the parameters of the vessel, including its position, its heading, its speed over ground and its course over ground, are obtained. Wind and/or current measurements in the proximity of the vessel are obtained using a device external to the vessel. The drift vector is determined from wind and/or current measurements. The over-ground vector is determined from the parameters selected from the position, the speed over ground and the course over ground of the vessel. The magnitude and the direction of the surface vector of the vessel is calculated.
