  • PROPULSION SHAFTING ALIGNMENT - Eagle. org
    Slope boring or the bearing inclination are used in marine industry to achieve the required level of alignment tolerances and more uniform load distribution over the bearing length
  • Ship motions - Wikipedia
    There are three special axes in any ship, called longitudinal, transverse and vertical axes The angular movements around them—affecting the ship's moment of inertia, which sets the torque it requires to rotate in any direction—are the ship's rotational motions (or rotary motions), known as roll, pitch, and yaw respectively
  • Righting Arm-Righting Moment-Finished. xls
    STEPS Your vessel's drafts are: FWD 22'-04", AFT 22'-10"; and the KG is 18 4 feet Use the selected stability curves in the blue pages of the Stability Data Reference Book to determine the righting arm at 30° inclination
  • What Is Heel Angle and How Does It Affect Vessel Stability?
    Heel angle is the actual measure of this inclination, taken from the vertical centerline of the ship It is important to distinguish between heel and list, though both describe a transverse inclination
  • HANDBOOK OF DAMAGE CONTROL - PART 2 - Maritime
    There are certain factors which may cause either W or GZ to vary It is the purpose of this discussion to consider some of these variations, and to develop a method of describing a ship's total stability characteristics 4-2 Righting arm and angle of heel If the angle of heel is small, the metacenter may be regarded as being fixed
  • All you ever wanted to know about Under Keel Clearance… but were afraid . . .
    From calculating static UKC to understanding squat and honing UKC management techniques, Dr Tim Gourlay explains the basics The first aspect to consider is the static Under Keel Clearance – that is, how much water is left between the bottom of the ship and the seabed
  • 3. 5 Calculation of stability curves - IMORULES
    Hydrostatic and stability curves should be prepared for the trim range of operating loading conditions taking into account the change in trim due to heel (free trim hydrostatic calculation) The calculations should take into account the volume to the upper surface of the deck sheathing
  • WHITEPAPER Inclining guide - saltwater. nl
    This whitepaper is intended for vessel owners, operators or anyone with an interest in the theory to provide a better understanding why, how and when an inclination test is prepared and executed
  • STABILITY - United States Naval Academy
    The process of obtaining the actual intact statical stability curve is done by reading values off the “cross curves of stability” for a given displacement of the ship, and then making a sine correction to account for the proper vertical location of the center of gravity of the operating ship
