Introduction to hydro-dynamics affecting off-shore structures and underwater pipelines:
Loads on thin cylindrical elements due to wave action. Morrison’s formula for vertical and inclined elements. Mooring systems and loadings due to wave action and operational loads. The hydrostatic stability of floating structures. Underwater pipelines.
|1||Introduction||First order wave theory for monochromatic waves. Formulation of the interaction problem on sea waves and solid objects. Solution for specific cases - Application Examples.||1Χ3=3|
|2||Morrison’s equation for vertical and inclined elements||Hydrodynamic loads on cylindrical members of small diameter and on large bodies||3Χ3=9|
|3||Mooring systems||Static and dynamic analysis of mooring lines/cables||3Χ3=9|
|4||The hydrostatic stability of floating structures||Hydrostatic stability. Definition of floating device failure.||2Χ3=6|
|5||Underwater pipelines||Estimation of hydro-dynamic loads. The stability of underwater pipelines. Recommendations on the design and lying of undersea pipelines.||4Χ3=12|
Upon successful completion of the course, students will be able to solve complex problems related to the calculation of hydrodynamic loads on:
• marine offshore structures, • mooring systems submarines • floating structures and • underwater pipelines.
|Teaching methods||Lectures in class. Solving of simple examples and problems in the class. Discussion of case studies.|
|Teaching media||Presentations in the Table. PowerPoint Slides. Calculations on PC via Excel and computational codes.|
|Computer and software use||Students solve complex simulations of coastal processes using PC at home and at the Laboratory of Harbour Works.|
|Problems - Applications||Yes|
|Assignments (projects, reports)||Students, complete projects during the semester with the continuous supervision of the teachers. For each topic they write a Technical Report, which is corrected by the teachers and returned.|
|Other||Educational Excursion. There is an option of developing individual voluntary bibliographic work.|
