Ship recycling yards around the world offer a price to the ship owners for buying an obsolete vessel to demolish and recycle based on the ship's end-of-life weight. The offer price is mainly based on the type of ship and the estimated quantity of steel available. The steel weight estimation, in terms of percentage of lightweight (LDT), is...

The performance of a ship’s rudder largely determines its manoeuvrability, which includes turning ability, initial turning ability, yaw-checking ability and course-keeping ability. However, existing empirical formulas for rudder forces do not concern the rudder profile. This paper discusses the impacts of various rudder profiles on ship...

To meet the expected increase of seaborne trade flows for coal and iron ore dry bulk terminals need to be designed or expanded. A comprehensive design method for dry bulk terminals is missing. Designs are currently based on rules-of-thumb, practical experiences and average values for specific design criteria. In this research, additions to...

This research focusses on the use of consistent scenarios to help ship owners, banks and other parties with an interest the maritime business get a better grip on the future. Three levels of detail can be distinguished for the maritime industry. The macroeconomic level is the highest and focusses on the behaviour of countries and the trade...

This book gives an overview of cutting theories. It starts with a generic model, which is valid for all types of soil (sand, clay and rock) after which the specifics of dry sand, water saturated sand, clay, rock and hyperbaric rock are covered. For each soil type small blade angles and large blade angles, resulting in a wedge in front of the...

In dredging practice jetting is widely used for the excavation of soil. In this study the jetting process of a moving vertical jet in cohesive soil has been investigated. A number of jet tests were conducted on artificially prepared cohesive soil samples. The observed failure mechanisms are discussed. A calculation model to predict the jet...

The European inland waterway transport sector is a highly competitive one. The transport operators in this sector are mainly small companies with only one ship. Such companies have very few possibilities to distinguish themselves from their competitors. At the same time their main asset, their ship, is often highly standardized. In this thesis,...

Background At the start of a design it is often good to look at comparable designs. What choices were made, what are the operations, what equipment is used? This report looks at three Damen ships, which are already capable of offshore support. These vessels are designed for open water. Looking just at what has to improve for operating in the...

Background The Dutch maritime industry has only limited knowledge about Arctic engineering, in spite of a growing market and interest by the oil and gas industry. This literature survey is the first in a series of three reports to develop a concept design of an Arctic Offshore Support Vessel (AOSV). The purpose is to give a perspective on Arctic...

Airlines invest a lot of money before opening new pax transportation services, for this reason, airlines have to analyze if their profits will overcome the amount of money they have to invest to open new services. The design and analysis of the feasibility of airlines networks can be done by using the models developed in this thesis. It is...

Cavitation erosion is one of the remarkable catastrophic consequences of cavitation. Predicting the cavitation aggressiveness quantitatively and predicting the most probable location of cavitation erosion are complex problems that currently still motivate an important amount of basic and applied research in the fields of hydrodynamics, physics...

The most important characteristics of the outfitting processes in shipbuilding are: 1. The processes involve many interferences between yard and different subcontractors. In recent years, the use of outsourcing and subcontracting has become a widespread strategy of western shipyards. There exists not only the vertical relationship between a yard...

<Subject and main objective> There is a desire to assess extreme wave loads on offshore structures like Floating Production, Storage and Offloading (FPSO) vessels, either for design, or for evaluation when circumstances near the structure change. Design formulae for extreme wave loads are scarce and have limited validity for specific structures....

This paper examines the effects that low-cost carriers (LCC’s) produce when entering new routes operated only by full-service carriers (FSC’s) and routes operated by low-cost carriers in competition with full-service carriers. A mathematical model has been developed to determine what routes should be operated by a low-cost carrier with better...

Naval architects often say that every ship is a compromise between many conflicting requirements. This widely-held belief immediately raises the question as to what kind of ship and, therefore, what kind of compromise, would suit the ship owner’s interest best. The approach presented in this thesis aims to improve the early stage design process...

This dissertation proposes strategies not only for modelling price behavior in the dry bulk market, but also for modelling relationships between economic and technical variables of dry bulk ships, by using modern time series approaches, Monte Carlo simulation and other economic techniques. The time series modelling techniques, described...

In recent years, great progress has been made in both the optimisation of the seakeeping behaviour of fast ships and the development of efficient numerical methods for computation of the seakeeping behaviour of ships in general. The study presented in the thesis aims to integrate both developments. First, the key aspects of the seakeeping...

Belt conveyors have been used worldwide in continuous material transport for about 250 years. Traditional inspection and monitoring of large-scale belt conveyors focus on individual critical components and response to catastrophic system failures. To prevent operational problems caused by the lack of experience of maintenance personnel, the...
