In offshore offloading operations, two vessels in a side-by-side configuration experience actions of both ambient water waves and liquid sloshing in internal tanks. Under the excitation of water waves, complex multibody motions are induced, resulting

This paper describes the development of data-driven models for the prediction of mooring line tensions by separating the low- and wave-frequency components of the tensions, such that the former is approximated as quasi-static tensions while the latte

This paper presents verification of a deep water FPSO with a semi-taut mooring system using model tests and numerical modelling commonly referred to as the hybrid method. The vessel under investigation is a FPSO of 310m in length and 47m in beam with

In the field of offshore renewable energy, impermeable plates are used as underwater lenses to amplify the wave amplitude, and perforated plates can harness wave energy as a power takeoff device. Within the framework of the linear potential-flow theo

An analysis framework is developed in this paper, to model the behaviour of a partially-entrapped water volume between two vessels in a side-by-side arrangement. The framework is based on a viscous CFD model and comprises two components, namely, an a

Numerical investigations of hydrodynamic interactions between side-by-side barges, in terms of gap free-surface response and forcings, are carried out using the analysis framework developed in Part I. The barges are assumed to be rigidly fixed. Two s

In order to extend the operational weather window for marine vessels under Dynamic Positioning (DP) control, a novel sea state identification method with multi-layer classifiers is proposed in this paper. Due to the distinction of system responses fo
