A computer implemented method and apparatus for a marine vessel data system, the method comprising: receiving data from at least one sensor configured to measure vibration and operationally arranged to the marine vessel to provide time-domain reference sensor data; maintaining the time-domain reference sensor data within a data storage system; generating a Fast Fourier Transform (FFT) on the time-domain reference sensor data to provide a plurality of reference spectra files in frequency-domain, wherein each reference spectra file comprises spectra data defined by amplitude information and frequency information, and each spectra file is associated with condition information determined based on collection of the time-domain reference sensor data; normalizing each reference spectra file by converting the frequency information to order information using the condition information to provide normalized reference spectra files; and training a convolutional autoencoder type of neural network using the normalized reference spectra files.

A marine outboard engine including an engine unit; a drive unit operatively connected to the engine unit; an engine unit housing for supporting and covering the engine unit, the engine unit housing having a top surface; and one or more bumpers connected to the engine unit housing. The bumper projects above the top surface of the engine unit housing; or rearward of an upper rear end of the engine unit housing; or both above the top surface of the engine unit housing and rearward of an upper rear end of the engine unit housing. When the marine outboard engine is located under a boat hatch is in a closed position and the marine outboard engine is pivoted in at least one portion of a tilt range, the bumper is adapted for abutting a bottom surface of the hatch.

A watercraft mounting system that embodies a moving mounting platform and a protective hull cavity which provides protection, prevents damage and improves storage of data collection systems.

The invention relates to a ship, comprising: at least one casing that delimits a cavity extending vertically across the ship's decks; at least one exhaust flue that is installed inside said casing and comprises a plurality of concentrated mass components and a plurality of components with mass distributed in length; a plurality of structures that support the plurality of said components inside the casing. Said support structures comprise: a plurality of main platforms, which define a main support base inside said cavity and is connected to walls of the casing at a ship deck by means of the interposition of main elastic suspensions; and a plurality of secondary platforms, which are directly or indirectly supported only by one of said main platforms and defines a secondary support base arranged at a different height with respect to the main support base that is defined by the corresponding main platform.

The invention relates to a sensor fastener arrangement (10a-f) for holding a sensor device (3). The sensor fastener arrangement (10a-f) comprises a plurality of fastener elements (20a, 20b). The fastener elements (20a, 20b) are configured to arrange the sensor device (3) to a platform (1). Respective fastener element (20a, 20b) is rigid in a first state and reversibly deformable in a second state. When the platform (1) of the sensor device (10a-f), and/or the sensor device (3), is exposed to an impact force, in turn exposing a fastener element (20a, 20b) to a compressive force exceeding a critical load of that fastener element (20a, 20b), the fastener element (20a, 20b) goes from being in the first state to temporarily being in the second state. Thereby the fastener element (20a, 20b) goes from having a first rigid shape to temporarily being reversibly deformed, after which, when the impact force is terminated, the fastener element (20a, 20b) goes from temporarily being in the second state back to being in the first state. Thereby the fastener element (20a, 20b) goes from temporarily being reversibly deformed to having the first rigid shape.
