Numerical simulation of piggyback pipelaying under current loadings
Lee, Chern Fong; Ji, Guomin; Janocha, Marek Jan; Ong, Muk Chen; Borsheim, Andreas (Peer reviewed; Journal article, 2023)For piggyback pipelaying operations, current-induced force and its effect on the piggyback pipe have not been thoroughly studied. In the present study, an improved method in hydrodynamic load calculation and structural ... -
On-bottom Stability of a Subsea pipeline in Irregular Waves
Li, Lanjing (Masteroppgave/UIS-TN-IKM/2016;, Master thesis, 2016-06)Pipelines in a subsea environment are exposed to a very complex system of hydrodynamic reaction. The on-bottom stability has long been a important study for offshore practice. The soil types, wave conditions as well as ... -
On-Bottom Stability of Umbilicals and Power Cables for Offshore Wind Applications
Ji, Guomin; Ong, Muk Chen (Peer reviewed; Journal article, 2019)With the increase in offshore wind farms, the demands for umbilicals and power cables have increased. The on-bottom stability of umbilicals and power cables under the combined wave and current loading is the most challenging ... -
Pipelaying Simulation for Pipelines with and without Piggyback in Ultra-Deep Water
Borsheim, Andreas (Masteroppgave/UIS-TN-IMBM/2019;, Master thesis, 2019-06-15)Pipelaying operations are pushing the boundaries of installation depth from midwater to ultra-deepwater. Parameters such as combined loading, top tension, and current loading must be investigated appropriately to ensure ...
