In this study, the dynamic responses of an oil tanker moored on a Catenary Anchor Leg Mooring (CALM) buoy were simulated under wave, wind and current through numerical simulations. Then tension mooring lines drift range studied after system failure. Simulations done with ANSYS AQWA Orcina OrcaFlex. Hydrodynamics was first solved in frequency domain based potential theory, three-dimensional radi...

The paper aims at proposing a criterion to optimize the initial level of spare parts inventory for a ship. Adequate stockholding of critical spare parts becomes essential in naval industry characterized by heavy utilization of equipment and machinery and by really specific operating conditions. Generic approaches are inadequate and specific ones result in analysis too shallow. An application fo...

This study investigated the effects of pneumatic fenders on prevention structural damage from collisions between a ship-shaped offshore installation and shuttle tanker during side-by-side offloading operations. A nonlinear finite element modelling technique was developed to simulate kinetic energy absorption behaviour collisions. Full-scale were physically tested validate computational model at...

Movie directors and designers of displays for process control have one thing in common: they must display the inner state of a complex system in an understandable way to a group of spectators/operators that do not have direct access to the interior of the system. The paper redefines the three basic filmic units, cut, scene and sequence, and presents five topics from film theory that may give in...

More than 90% of world trade is transported by sea. The size and speed of ships is rapidly increasing in order to boost economic efficiency. If ships collide, the damage and cost can be astronomical. It is very difficult for officers to ascertain routes that will avoid collisions, especially when multiple ships travel the same waters. There are several ways to prevent ship colli...

Mandatory or voluntary reductions in ship speed are a common management strategy for reducing deleterious encounters between large ships and large whales. This has produced strong resistance from shipping and marine transportation entities, in part because very few studies have empirically demonstrated whether or to what degree ship speed influences ship-whale encounters. Here we present the re...

Magnetohydrodynamic (MHD) ships represent a clear demonstration of the Lorentz force in fluids, which explains the number of students practicals or exercises described on the web. However, the related literature is rather specific and no complete comparison between theory and typical small scale experiments is currently available. This work provides, in a self-consistent framework, a detailed p...
