Ship Collision Accidents and Simulation of Small Ship Collision to Fender System of Bridges

PROCEEDINGS OF CIVIL ENGINEERING IN THE OCEAN, 1996
First of all, ship collision accidents in Japan are collected and analyzed. Experimental results by the hydraulic model test for ship's impact force to fender systems which protected piers of bridges from ship collision are discussed. The numerical simulation model to evaluate ship motions and fender deflections by ship collision are also presented and

A Decision-Making Method for Ship Collision Avoidance Based on Improved Cultural Particle Swarm

Journal of Advanced Transportation, 2021
In the process of ship collision avoidance decision making, steering collision avoidance is the most frequently adopted collision avoidance method. In order to obtain an effective and reasonable steering angle, this paper proposes a decision-making ...

On the global ship hull bending energy in ship collisions [PDF]

Marine Structures, 2009
Abstract During ship collisions part of the kinetic energy of the involved vessels immediately prior to contact is absorbed as energy dissipated by crushing of the hull structures, by friction and by elastic energy. The purpose of this report is to present an estimate of the elastic energy that can be stored in elastic hull vibrations during a ship ...

The Global Supply Chain Resilience Paradox as an Ethical Dilemma: Trade‐offs, Tensions, and Multilevel Strategies in Times of Crisis and Disruption

Business Strategy and the Environment, EarlyView.
ABSTRACT This research examines the resilience paradox in global supply chains, exploring how trade‐offs between economic and social‐ecological resilience escalate into managerial dilemmas under high environmental uncertainty. Using an abductive theory extension approach, we analyse a multinational automotive supply chain case during the Covid‐19 ...

Systematic Study on Phosphatidylethanol (PEth) Stability and De Novo Formation in Authentic Whole Blood Samples

Drug Testing and Analysis, EarlyView.
PEth 16:0/18:1 was stable for at least 5 months when stored at −20°C/−80°C and during non‐temperature controlled postal transport, but PEth 16:0/18:2 showed rapid degradation during transport and at room temperature (RT). Significant Peth 16:0/18:1 de novo formation was observed when stored at −20°C and RT as early as 14 h after sample collection ...
