Ettema, Bart (author)
The yacht building industry is considered an industry with a high environmental impact. Until now, the focus has not been on the impact regarding business processes of the building phase and the excess in resources that are used, ultimately not adding value to the final product. Due to emerging trends in regulations, new sustainable production...

As liquid bulk vessels are berthed in ports, auxiliary engines generate the electrical power demand, which emissions have a negative effect on the environment and local air quality in ports. Shore power is an effective solution for this problem. However, the large costs of implementing shore power and the absence of a technical safe design...

With the growing shortage of seafaring personnel, on­board systems need to be more reliable to beable to sail without. Multiple efforts are done to be able to sail with unmanned systems (systems thatdon’t need maintenance while sailing), but for large unmanned surface vehicles, the P&P system isone of the systems that is not reliable enough....

The current path the marine industry is following, the goals of the Paris Agreement to reduce emissions, will not be met. The marine industry is mainly sailing on HFO and emits 2.2% of the global greenhouse gasses (GHG) by doing so, as well as 18-30% of NOx, 5-8% SOx and 11% particulate matter (PM). The IMO has even predicted that the emissions...

In the volatile and demanding current market and in view of frequent implementation of new emission regulations, ship renovations entail more and more radical conversions of higher complexity. Application of optimization methods in the ship maintenance, repair, and conversion industry have been so far frequently overlooked, due to the former...

This research aims to determine the cost effectiveness of yacht emission reducing ret options through marginal abatement cost curves. A broad selection of five refit options is evaluated and implemented in the created tool. Using multiple scenarios by fluctuating fuel price and the implementation of hydrotreated vegetable oil (HVO), the effect...

The energy transition of Dutch shipping will be a complex gradual process due to the variety, cost and lifetime of vessels. The uncertainty in transition pathway, additional costs of climate neutral alternatives and required regulatory changes also form transition barriers. This thesis aims to create a holistic overview of both the transition...

Current challenges at Damen Technical Cooperation (DTC), regarding an imperfect procedure for documentation sharing, misalignment and quality issues in documentation flow, are the motivation for this master thesis. DTC is a company within the Damen Group that offers a unique service for shipyards; a variety of material and service packages to...

In this study, various scenarios were developed that correspond to estimations of future biomass availability and biofuel demand from the maritime industry. These marine biofuel demand scenarios were based on the Greenhouse Gas (GHG) reduction targets of the Renewable Energy Directive II (RED II) and the International Maritime Organization (IMO)...

Muhammad Fareza, Reza (author)
The shipbuilding industry is not a standalone industry. It integrates with the shipping market, and therefore one characteristic of the shipbuilding industry is complexity. Competitiveness is a multi-dimensional concept that can be measured in numerous ways. The author found that these multi-dimensional concepts can better be translated into...

Douma, E.T. (author)
To identify and improve the communication or information flow for a ship production process, this thesis provides an approach to use a Discrete Event Simulation (DES) model, based on Petri Net technique. By establishing a theoretical framework, the different simulation modelling options are analysed and based on practical requirements, a choice...

Moussault, Sietske (author)
The current operational cost estimate applied by shipping management companies is insufficiently valid and accurate for determining the operational budget. Most shipping management companies include scheduled maintenance jobs in the operational cost calculation. Scheduled maintenance does not take unforeseen maintenance into account. In...

Bodewes, Wijnand (author)
The shipping industry needs to reduce greenhouse gas emissions and other pollutants. In order to achieve this reduction, the shipping industry will be faced with stricter regulations that are currently unclear. The lifetime of a ship is about 25 years. As a result, it can be interesting to already take a possible refit to an alternative fuel...

Bregt, Tijmen (author)
During the start of a project organisations make estimation on the expected amount of work and the corresponding project duration, the lead time. To make these estimations with a low uncertainty is important because a false estimation could result in cost overruns and project delay. This paper proposes an estimation and planning maturity...

The supply for luxury yachts is growing which increases the competition between yachtbuilders. Additionally to lead time reduction, yachtbuilders are trying to maximise their output with the available space. This puts extra pressure on the logistics process. Waste in the logistics process reduces the efficiency and for that must be avoided. The...

Defects are produced when lifting lugs being welded on ship sections during the building process. The large amount of heat produced in the welding work causes “heat affected zone” in the base metal on sections and destroys painted coatings on the plates; and residual stress decreases the mechanical performance of the steel plates. To eliminate...
