Port Pricing Structures and Ship Efficiency

The paper discusses port pricing structures that enhance ship efficiency. Traditionally, ports use public infrastructure pricing, which does not take differences in waiting cost into considerations. We present two alternatives, a two part priority pricing scheme and port slot auctions, as alternative scheduling and pricing schemes that enhance ship efficiency.

A procedure to optimize ship side structures for crashworthiness

This paper presents a procedure to optimize a conceptual ship side structure from a crashworthiness point of view. As an example, this procedure is presented for a chemical or product tanker. A particle swarm optimization algorithm is used for the procedure. The classification society compliance of the conceptual design is checked through service loads that are applied to the ship’s hull girder...

Reliability-Based Methodology for Life Prediction of Ship Structures

Recent advances in structural analysis technology such as the finite element method, improvements in the ability to model realistic sea loads, development of fatigue and fracture mechanics methods, development of reliability analysis methods, and the rapid advancements in computing technology, make it possible to develop methods to evaluate the structural strength of a ship, considering the req...
