A flexible method for the initial prediction of tugs escort capability

نویسندگان

چکیده

Preliminary prediction of escort tug capability aims to identify the maximum steering and braking forces could deliver during operations at sea. To this end, adoption a steady-state equilibrium approximation ensures attaining quick enough accurate results for initial design stage. Diverse techniques are suitable resolve equilibrium, with different simplification levels related limitations. In study, method based on nonlinear thrust allocation algorithm is improved, including propulsors interactions. Moreover, addition transversal modelling allows evaluating compliancy stability safety Regulations class. The coupling between enhanced resolution simplified approach estimate hydrodynamic in flexible capability, which requiring few inputs, without excluding possibility use higher fidelity loads. calculation framework, implemented confidence loads, tested types, highlighting its flexibility compared more traditional widely accepted approaches • Modelling thruster–thruster interaction effects inside procedure. Application heeling limitations safe operations. Different righting arm curve Enhanced framework types.

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

Performance Prediction of a Flexible Manufacturing System

The present investigation presents a stochastic model for a flexible manufacturing system consisting of flexible machine, loading/unloading robot and an automated pallethandling device. We consider unreliable flexible manufacturing cell (FMC) wherein machine and robot operate under individual as well as common cause random failures. The pallethandling system is completely reliable. The pallet o...
