The Quasi-Static Response of Moored Floating Structures Based on Minimization of Mechanical Energy

open access: yesJournal of Marine Science and Engineering, 2021
It is essential to design a reasonable mooring line length that ensures quasi-static responses of moored floating structures are within an acceptable level, and that reduces the cost of mooring lines in the overall project. Quasi-static responses include

Influence of Clumps-Weighted Moorings on a Spar Buoy Offshore Wind Turbine

open access: yesEnergies, 2020
The spar buoy platform for offshore wind turbines is the most utilized type and the OC3 Hywind system design is largely used in research. This system is usually moored with three catenary cables with 120° between each other.

Moore–Penrose inverse positivity of interval matrices

open access: yesLinear 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

open access: yesSensors, 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
