ship motion

ship motion

[′ship ‚mō·shən]
(engineering)
Translational and rotational motions of a ship in a wave system which cause the center of gravity to deviate from simple straight-line motion; these motions are heave, surge, sway, roll, pitch, and yaw.

As mobile platforms, ships are usually equipped with gimbal inertial navigation system or gimbal compass/log and other high accuracy navigation equipment to provide the ship motion information including speed, position, and attitude.

Development of the WISDAM code for ship motion simulations
They go from a basic bridge system that has yet to be tried on a vessel to a complex package of hydraulics that compensate for ship motion.
In this particular ship motion model, an extra term is added due to the ship movement along the z-axis and it depends on the period [T.
The work has been carried out by the maritime research consultancy Cetena, which has a history of designing individual ship motion monitoring systems, and implemented using standard CompactRio and LabView from National Instruments by the Genoa-based systems integrator Sitem.
My copilot had an extremely difficult time maintaining position because of the excessive ship motion (pitch 3 to 4 degrees, rolls 8 to 10 degrees and occasionally greater).
Navy researchers, for example, are working on a ship motion detector that will allow a UAV to gauge the safety of a landing by measuring the pitch and roll of the ship.
The critical ship motion responses and sloshing impact conditions were calculated with North Atlantic environment conditions.
spaces things are happening if the public space is below or above the stateroom) Lower deck Less expensive; Possibly far from public less motion felt spaces; may be smaller staterooms Higher deck Possibly closer to More expensive; possibly public areas; closer to more "traffic"; potential "sun" deck and pool; to feel more ship motion feels more prestigious; often larger staterooms
The team was formed to engineer a shipboard antenna system to acquire, receive and record telemetry data from the Trident II D5 missile during test flights, and after completing a six-month initial concept evaluation, a phased array telemetry system was selected to meet the large field-of-view requirement and to avoid the need to compensate for ship motion (roll and pitch).
The team is using two motion generators for the study, the vertical linear oscillator at Brandeis and the ship motion simulator at NRL's Chesapeake Bay Detachment, to understand how ship motion in various sea states affects the simulator user.
