Analysis and Tests of the Behavior of an Underwater Acoustic Horizontal Array Platform
한국해양공학회지, 2018 Most underwater acoustic arrays for low frequency operation are deployed vertically, but a mid-range frequency horizontal array system is being developed by the Korea Research Institute of Ships and Ocean Engineering (KRISO).

High multiplicity of positive solutions in a superlinear problem of Moore–Nehari type
Communications in Nonlinear Science and Numerical SimulationIn this paper we consider a superlinear one-dimensional elliptic boundary value problem that generalizes the one studied by Moore and Nehari in [43]. Specifically, we deal with piecewise-constant weight functions in front of the nonlinearity with an arbitrary number $κ\geq 1$ of vanishing regions. We study, from an analytic and numerical point of view,

H ∞ Controller Design for Dynamic Positioning of a Turret Moored FPSO
IFAC Proceedings Volumes, 2000 Abstract This paper presents the controller design of a dynamic positioning system for a FPSO-turret moored in deep water, using a H ∞ methodology. The controller must counteract slow-drift oscillations due to waves and static offsets induced by current, wind and waves.

Dynamic analysis of submersible gravity-type fish cages with single-point mooring design
Journal of Ocean Engineering and ScienceThis study presents a conceptual design for a cost-effective submersible gravity-type fish cage with a single-point mooring design. The performance of the new design in reducing environmental loads under extreme sea conditions is demonstrated using an in-

International Journal of Coastal and Offshore Engineering, 2016 Developed mooring unit, the MoorMaster, which replaces conventional mooring lines is addressed here. The hydraulics of the system have a strong deducting effects on the motions of the moored ship. MoorMaster act in two different states.

Fault-Tolerant Control of Thruster-Assisted Position Mooring System
, 2015 This thesis fo cu ses on the fau lt-to lerant control al gor ithm o f the thr u ster-assiste d posi tio n moor ing system ( TAPM). TAPM is an energy-efficient and reliable stationkeeping method for deep water structures. System failures significantly endanger the marine control systems, and ultimately reduce the reliability and safety during operation ...
