Tikai, Karan (author)As the exploration for oil and gas is shifting towards greater water depths, there is a market for subsea rock installation (SRI) at these large water depths as well. Boskalis is a key player in the rock installation market and installing rock material at water depths of approximately 3000 meters is still far from routine work. Therefore,...master thesis 2020

van der Helm, Jonathan (author)An enhanced methodology is proposed to include both the loading and the resistance of the upper stem (pipeline) in 18" ILT installation. Loading behavior and buckling capacity have been investigated. The upper stem behaves quasi-statically for all HMC projects, this corresponds to the current method of applying maximum found loads statically....master thesis 2018

Teddy Andreas Simanjuntak, Teddy (author)During S-lay pipeline installation, tension fluctuations in the suspended pipeline are compensated by the tensioner system on the vessel. The goal of this thesis is to answer the questions: to what extent does the active tension compensation (ATC) influence the pipeline integrity during offshore installation. Secondly, which tensioner model...master thesis 2017

Sri Paravastu, R.K. (author)Offshore pipeline installation is limited by pipeline integrity during the laying process. Pipeline integrity is evaluated with the help of buckling checks, which help determining the feasibility of pipeline installation for a given sea condition. The operational limit of pipeline installation is determined during project preparation, by...master thesis 2016

Van Aubel, J.F. (author)When harsh weather conditions are expected during an offshore pipeline operation, the decision to start the abandonment procedure has to be taken based on pipeline integrity limits. The pipeline integrity which is analysed by a maximum design sea state does not correspond to the situation offshore, because sea states always occur in a different...master thesis 2015
