DEDICATION (NO REQUIRED FOR RESEARCH PAPER) (The dedication, as the name suggests is a Key words: Steel pipeline, Flexible pipeline, Installation, Sideway current, Makassar Strait, OrcaFlexPages: 133 + enclosure: CD Contains OrcaFlex filesAbstract This master thesis is describing the theoretical & analytical principles of pipeline installation. A page and one-half is approximately 350 words.) iii. A thesis abstract should consist of 350 words or less including the heading.
Fortunately the program OrcaFlex is capable to do both analyses. First step is a static analysis and the second is a dynamic analysis. Analysis will be carried out in 2 steps.
Same criteria apply to the lateral links. Tension forces in a vertical link will represent stinger roller reactions when the pipe is sitting on the roller, and zero force will represent a pipe lift-off. The idea is that these links will act as “roller” restraints. The links are restricted to only accept tension forces without any shear forces or bending moments.
This end represents the barge tensioner. The upper end of the pipeline is fixed to the barge and will not accept torsion. These lateral links are simple but very useful components for the model to reach its equilibrium during iterations.
First of all, I would like to give sincere gratitude to my supervisor Prof. OrcaFlex outputs will be observed to find out which scenario gives the “worst” condition during pipe-lay.Acknowledgement This thesis work is prepared to fulfill the requirement in the Master of Science degree in the Faculty of Natural Science and Technology in University of Stavanger. Cases presented will be named based on these directions. In this project the directions will be 0°, 30°, 60°, 90°, 120°, 150°, and 180°. Different direction scenarios will be taken for the current.
