Assessment of methods for short-term analysis of riser collision probability
Fu, Ping; Leira, Bernt Johan; Myrhaug, Dag; Chai, Wei (Peer reviewed; Journal article, 2021)Reliability- and performance-based design of a riser cluster requires an accurate estimation of the extreme values of the stochastic relative distance between the risers during a given time duration. This study presents a ... -
Assessment of Methods for Short-Term Extreme Value Analysis of Riser Collision
Fu, Ping; Leira, Bernt Johan; Myrhaug, Dag (Chapter, 2018)Risers are commonly arranged as clusters with relatively small spacing due to economic necessity. As a consequence, collision between risers becomes an essential problem. This study presents a comprehensive assessment of ... -
Discussion/comments regarding "Sea spray icing phenomena on marine vessels and offshore structures: Review and formulation" by A.R. Dehghani-Sanij, S.R. Dehghani, G.F. Naterer, Y.S. Muzychka
Myrhaug, Dag; Fu, Ping (Journal article; Peer reviewed, 2017)The purpose of this discussion is to demonstrate how the formula for the liquid water content in wind-generated seawater spray presented by Dehghani-Sanij et al. (2017) in conjunction with available wind speed statistics ... -
Reliability analysis of wake-induced collision of flexible risers
Fu, Ping; Leira, Bernt Johan; Myrhaug, Dag (Journal article; Peer reviewed, 2017)Collision between risers is an important design and operational concern, especially in deep water since the probability of collision tends to increase as the riser length increases. Riser collision is due to the joint ... -
Reliability Analysis of Wake-induced Riser Collision
Fu, Ping (Doctoral theses at NTNU;2019:91, Doctoral thesis, 2019)Reliability-based design of a riser array requires accurate estimation of extremes of the stochastic relative motion process between pairs of risers in order to avoid collision. Hydrodynamic interference is considered to ... -
Reliability-based safety factor for metallic strip flexible pipe subjected to external pressure
Liu, Ting; Leira, Bernt Johan; Fu, Ping; Bai, Yong; Liu, Dahui (Journal article; Peer reviewed, 2018)Reliability-based safety factors for metallic strip flexible pipes(MSFP) subjected to external pressure are calibrated in this paper. The partial safety factors of such pipes are obtained by introducing a target reliability ... -
SCOUR BELOW PIPELINES AND AROUND VERTICAL PILES DUE TO RANDOM WAVES PLUS CURRENT ON MILD SLOPES
Fu, Ping (Master thesis, 2014)This thesis presents a stochastic method for predicting the scour depth around vertical circular slender piles and below marine pipelines due to random waves plus current on mild sloping seabeds. An overview of the scour ... -
Scour below pipelines due to random waves alone and random waves plus currents on mild slopes
Myrhaug, Dag; Fu, Ping; Ong, Muk Chen (Journal article, 2017)This paper provides a practical stochastic method by which the maximum equilibrium scour depth below a pipeline exposed to random waves plus a current on mild slopes can be derived. The approach is based on assuming the ... -
Static analysis of interaction between two adjacent top tensioned risers with consideration of wake effects
Leira, Bernt Johan; Sævik, Svein; Fu, Ping; Tian, Deqiang; Fan, Honghai (Peer reviewed; Journal article, 2019)Collision between adjacent risers has become an important issue as the oil and gas industry moves to deeper waters. In order to estimate the clearance between two marine risers, a static analysis which is mainly concerned ... -
The effect of local wake model on collision probability for risers subjected to current and random waves
Fu, Ping; Leira, Bernt Johan; Myrhaug, Dag (Journal article; Peer reviewed, 2018)The present paper provides a method to estimate the clearance between two flexible risers in tandem arrangement by taking into account the hydrodynamic wake interference when subjected to a current flow and a combined ... -
Wake Shielding Model Effect on Riser Dynamic Response
Fu, Ping; Leira, Bernt Johan; Myrhaug, Dag (Chapter, 2017)The paper provides a method to estimate the clearance between two flexible risers in tandem arrangement by taking into account the wake interference when subjected to a combined current plus waves flow. The wake interference ...
