ngle (휃) were measured using the three-axes fber-optics

gyroscope (FOG) equipped on the model. The rudder angle


(훿), rudder normal force (FN) and propeller thrust (TP) during maneuvering were measured using dynamo-meters
equipped on the model. Surge velocity (u) and lateral velocity (v) were obtained by diferentiating the position of the
model. Ship systems and their components provide detailed technical information needed for weight
assessment, price estimation and production planning. Ship classification systems have been developed
to provide to the yards and to the companies involved in the management and operation of ships tools
to support ship specifications, estimates of light ship weight, ship building (or repair) costs and
systematically sort listed information on the procurement of materials, equipment and services. In brief,
there are three basic ship classification systems namely : (a) MARAD (MARitime Administration) used
by the U.S.A. administration; (b) SWBS- Ship Work Breakdown Structure, used by the USA Navy and
(c) .SFI– developed by the Norge Skips Forsknings Institutt (NSFI) of Norway, and is now property of
XANTIC ().
