In this study, a dynamic model for large deformation of deepwater drilling riser considering
vortex-induced vibration (VIV) and actual ocean load was established. Nonlinear Van der …

A marine riser operated in deepwater could encounter harsh environmental conditions and
exhibit complex vibration phenomena which require thorough investigation, especially using …

Marine riser is a key equipment in offshore drilling operation, and failure of the riser can lead
to drilling moratorium; in severe cases, it may cause oil and gas leaks. In this paper, the time …

In this paper, numerical simulations of vortex-induced vibrations in a vertical top-tension
riser with a length-to-diameter ratio of 500 using our in-house code viv-FOAM-SJTU are …

Renewable energy is a prominent area of research within the energy sector, and the storage
of renewable energy represents an efficient method for its utilization. There are various …

In this paper, we investigated the cascade controller of a motor-driven deep-sea robot cable
system (MDRCS), which consists of the outer loop system and the inner loop system …

Offshore fields, specifically, deepwater oil and gas reserves, have been receiving increasing
attention with the increasing consumption of petroleum products. Marine risers are critical to …

In this paper, we propose a mathematical model meant to eliminate the vibration of deep-
sea robot lifting system with time-variant length and harsh environmental conditions. The …

The installation of a surface conductor in deepwater jet drilling is crucial for offshore oil and
gas development. This study investigates the interaction between the surface conductor and …

This paper represents an experimental and theoretical study of dynamic characteristics of
coupling resonance between a deep-water riser (DR) and a floating platform. The super …
