Ocean - Seakeeping & Manoeuvring

COURSE OUTLINE:

Seakeeping: Regular water waves – definition of ship motions – single degree of freedom motions in regular waves – uncoupled heave, pitch and roll motions – coupled heave and pitch motions – irregular waves - description of long crested waves by 2D spectrum – ship motions in 2D irregular waves – description of short-crested sea – ship motions in 3D irregular waves – dynamic effects – deck- wetness, slamming, relative motions, sea-sickness etc. – added resistance in waves – roll stabilization

Manoeuvring: Types of directional stability - linear equations of motions in horizontal plane – hydrodynamic derivatives – stability index – standard manoeuvres – turning circle, zigzag, pullout and spiral manoeuvres – roll during turn – experimental determination of hydrodynamic derivatives – straight-line, rotating arm and PMM experiments – description of control surface (rudder) – control derivatives
