The motivation for this study is the fast development of floating offshore wind energy and the
immature methodology and engineering practice related to predictions of vortex-induced …

Abstract Model tests of a top tensioned riser (TTR) model were carried out as a part of a joint
industry project, with the purpose of better understanding the dynamic behaviour of drilling …

The global demand for minerals has raised interest in the design and study of Deep-Sea
Mining (DSM) systems for minerals. In this study, the global dynamic responses of a DSM …

The safety of risers in hang-off states is a vital challenge in offshore oil and gas engineering.
A new hang-off system installed on top of risers is proposed for improving the security of …

In this study, the Euler–Bernoulli beam was used to calculate the mining riser under variable
tension by considering the riser as a beam vibration problem. The natural frequency and …

The paper presents the modelling of risers dynamics by means of the 3D formulation of the
lumped mass method (LMM). The lower marine riser package (LMRP) and blowout …

Overloading of a riser, with possible subsequent damage, can be caused when the bottom
end of the suspended riser encounters an obstacle during its relocation realized in reentry …

Offshore drilling risers and many production risers are top-tensioned risers (TTRs),
connecting the vessel and seabed via joints. External loads such as currents, waves, and …

Extreme storm-safe drilling riser, a solution to overcome high time cost of riser emergency
retrieval under the situation of the imminent typhoon arrival, is to modify the existing drilling …
