Real-time collision risk based safety management for vessel traffic in busy ports and waterways

Regional risk analysis and management of maritime accidents is one of the fundamental tasks for maritime safety management. With the heavy and complicated maritime traffic in the ports and waterways, accidents, especially ship collision accidents, have been continuously posing threats to the maritime transportation system. To achieve effective...

Ship collision on inflatable weirs: Case study: weirs in the Meuse

In the Meuse seven weirs are located in the Dutch reaches, controlling the water level to enable inland navigation through the river. The weirs are being scheduled for replacement, where weir Grave is the first one in 2028. They are reaching their end-of-life time. One of the main issues that became of more importance in the recent years is ship...

Analytical model to assess bending moments in wind turbine support structures subjected to ship collisions

The number of offshore wind farms is growing rapidly, which increases the likelihood of ship collisions with offshore wind turbines. Additionally, the cost of energy reduction for wind turbines is achieved due to radical design optimizations. Therefore, simple methods should be obtained to determine the offshore wind turbine response during ship...

Probabilistic Risk Analysis for Ship Collision-Theory and Application for Conventional and Autonomous Ships

Maritime transportation has been one of the major contributors to the global trade and economy. Accidents, however, have been continuously posing risks to individuals and societies in terms of loss of human life, economic and environmental consequences, etc. This thesis paid particular attention to the probabilistic risk analysis of ship...

Ship collision on temporary structures: Combi-walls under collision loading

When designing a construction pit adjacent to a navigation channel, the event of a ship colliding with the structure is something to take into account in the design of the pit. However, several aspects regarding ship collisions, i.e. the probability of occurrence of a collision, the magnitude of the collision force and the influence on the...

Integration of elliptical ship domains and velocity obstacles for ship collision candidate detection

The maritime shipping industry has been making significant contributions to the development of the regional and global economy. However, maritime accidents and their severe consequences have been posing an incrementing risk to the individuals and societies. It is therefore important to conduct risk analysis on such accidents to support...

Measuring ship collision risk in a dense traffic environment

Collision risk measurement is an essential topic for ship collision prevention. Many risk measures, i.e. DCPA/TCPA, etc., decouple the ship traffic into several pairs of ships and then evaluate the risk in each pair. This kind of measurement loses some information of the entire traffic and might include some biases in risk measurement,...

Deformable and energy absorbing protection against ship collision

The Netherlands is a country where people have to live with water, rather than fighting against it. This philosophy often requires interaction between infrastructure and waterways, where (hydraulic) structures are placed close to or even extending in the waterway, introducing the risk of ship collision. What makes this accidental load so...

Stormvloedkering Nieuwe Waterweg

Ontwerp voor een variant van de stormvloedkering in de Nieuwe Waterweg. De variant in de vorm van een Caission is uitgewerkt in dit rapport. Tevens is een onderzoek gedaan naar het effect van Scheepsaanvaringen met dit caisson.

Feasibility study of protection systems for bridge Piers at Deepwater

Protection systems against ship collision are studied in the first report for this thesis. Based on this initial study a number of 10 protection systems for bridge piers at deepwater (>100 m) are developed. As an example a proposed bridge pier for a bridge over the Strait of Gibraltar with a foundation depth of 300 m is chosen. The major...
