Design of automatic thruster assisted mooring systems for ships [PDF]
Modeling, Identification and Control, 1998 This paper addresses the mathematical modelling and controller design of an automatic thruster assisted position mooring system. Such control systems are applied to anchored floating production offloading and storage vessels and semi-subs. The controller

Moore–Penrose inverse positivity of interval matrices
Linear Algebra and its Applications, 2012 The authors study (entrywise) nonnegativity of the Moore-Penrose inverse \(C^\dag\) of a matrix \(C\in\mathbb{R}^{m\times n}\). In particular they consider the following questions: (1) When is \(C^\dag\) nonnegative? (2) When is \(C^\dag\) nonnegative if \(C\leq B\), where \(B\in \mathbb{R}^{m\times n}\) is a given matrix with \(B^\dag\geq 0\)?

Profile Autonomous Underwater Vehicle System for Offshore Surveys
Sensors, 2023 Offshore marine engineering, offshore aquaculture, and offshore environmental protection require periodic offshore surveys. At present, the main means of offshore marine surveys are mooring buoys and marine survey ships. Anchored buoys are fixed in place

Fatigue analysis on the mooring chain of a spread moored FPSO considering the OPB and IPB
International Journal of Naval Architecture and Ocean Engineering, 2019 The appropriate design of a mooring system to maintain the position of an offshore structure in deep sea under various environmental loads is important. Fatigue design of the mooring line considering OPB/IPB(out-of-plane bending/in-plane bending) became ...

Innovative Method for Ship Navigation Safety Risk Response in Landslide-Induced Wave
Advances in Civil Engineering, 2021 When the bank of a reservoir slope slides along a weak structural plane at a high speed, “landslide slamming” will occur in the nearby water. The formation of landslide-induced waves is a serious threat to the safety of wharfs, shore marks, buildings in ...

Experimental and Numerical Study of the Influence of Clumped Weights on a Scaled Mooring Line
Journal of Marine Science and Engineering, 2022 Recently, several experimental and numerical studies have underlined the advantages of adding clumped weights at discrete positions of mooring lines. To confirm the influence of these weights, an experimental study was performed for a 1:30 scale model of

Setpoint Chasing for Thruster-Assisted Position Mooring
IEEE Journal of Oceanic Engineering, 2007 This paper presents a new concept for control of thruster-assisted position moored vessel using setpoint chasing. The mooring system is designed to compensate the mean environmental loads up to a certain limit of the environmental conditions. In the present industrial position mooring (PM) system, the thrusters are used to damp the vessel’s dynamical ...
