A5 - Methods for estimating the fluid loading and response of slender structural elements used in offshore.
A6 - To provide knowledge of experimental methods and techniques adopted by offshore engineers and naval architects in the area of fluid loading and response.
A7 - To develop skills required to predict the functional performance and downtime for offshore vessels and installations.

Outline Of Syllabus

The module applies the fundamental marine dynamic principles to ships and various different types of platform concept in order to assess the environmental loafing and response. Topics include: prediction of environmental loads on fixed and floating offshore platforms; shallow and deep water wave theories; dynamic responses analysis and experimental techniques, dynamic modelling of offshore floating structures in waves; fluid loading on slender offshore structures; Froude Krylov forces; simplified diffraction forces; introduction to the Morison equation – fluid phenomenon and force coefficients, variations on the basic formula, fluid loading calculations; statistical description of random seas; two-dimensional and three-dimensional wave spectra; statistical description of response to environmental loading; downtime analysis; experimental facilities and their use including: wave basins, U-tube oscillating water tunnels, wind/wave/current facilities, towing tank and cavitation tunnels.

The module also provides an insight and understanding concerning the separated fluid flows related to the fluid loading of slender bodies, such as structural elements of fixed platforms and pipelines. Modelling aspects of ships and offshore structures in incompressible viscid/inviscid flow. Topics also include: fluid flow phenomena; relevant potential flow models; uni-directional flows - flow separation, vortex shedding; vortex induced vibration (VIV); Real oscillatory flows - the concept of added mass wave diffraction by large volume structures- McCamy and Fuchs solution.

Teaching Rationale And Relationship

The lectures provide the students with general understanding of and familiarity with the fundamentals of the fluid loading theory and practice. The lectures are also designed to assist students in the acquisition of a knowledge base that will facilitate understanding of concepts and detailed analysis methods (IKO1 – IKO7).

Example classes and tutorials help the students to develop the associated skills required for the solution of the fluid loading problem. The application of the method introduced will allow assessment of wave loadings and motions (ISO1-ISO7).

Assessment Rationale And Relationship

The examination provides students with an opportunity to demonstrate knowledge, understanding and the possession of subject-specific, cognitive and key skills. This medium also allows students to demonstrate intended learning outcomes across a wide range of topics within the syllabus.

Problem solving skill provides students with an opportunity to apply the taught professional skills and solve marine and offshore related engineering problems and provide depth of understanding (and associated cognitive skills).

The Graduate Skills Framework Skills indicated as 'A' are also assessed in this way.
