PERFORMANCE EVALUATION AND APPLICATION OF MOTION AND SEAKEEPING CHARACTERISTICS OF MODERN OFFSHORE SUPPLY VESSELS

Supply Vessels are increasingly being utilized in special purpose offshore support modes. Many of these operations are limited by the vessel's motion and seakeeping qualities. This paper presents a systematic study undertaken to determine the sensitivity of vessel responses in irregular head and beam seas, to variations in vessel dimensions. A typical chined hull form is selected as a basis and dimensions are varied to encompass the normal range of existing forms. Spectral methods and state of the art computer analytic techniques have been used to determine these characteristics. Results in head seas, are presented in a non-dimensional format so that geometrically similar vessels, of any length, in seastates with any combination of significant wave heights and periods may be derived. In this context, two specialty feature offshore applications of these vessels are discussed and a scheme for their performance evaluation is presented.
