Reducing the non-value added movements in the interior logistics process
Study provided by yachtbuilder Oceanco
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 logistic

Reducing emissions from short-sea ships
Cost effectiveness of available options
Strict regulations for carbon emissions from ships are introduced by the IMO and the EU. Various emission mitigation measures and low-emission fuel strategies provide solutions to reduce carbon emissions. This paper compares emission mitigation measures and low-emission fuel stra

Circular Economy in the Maritime Industry
Class notation S.U.R.V. Sustainable Use of Resource Vessel
Many recycled materials in different industries are traceable. The recycled content is often known in percentages. Steel is a material which gets recycled almost 100%. However it is not common practice to specify the recycled content for steel products. From a sustainability poin

Ship Design for Uncertainty
A Real Options Approach to determine the Value of Design-for-Conversion under Uncertainty
The maritime industry faces a lot of uncertainty, and the energy transition has only increased this uncertainty. Ships will probably have to be converted to an alternative fuel during their lifetime and methanol seems to be the fuel with the most potential for offshore ships. By

European Production of Biofuels for the Maritime Industry
A MILP optimization of biofuel supply chains to minimize costs and emissions for the first phase of the Energy Transition
The maritime industry has long relied on oils and heavy fuels as main energy carriers. The shipping sector still accounts for an important 2.5% of global greenhouse gas emissions. On top of this, current industry fuels contain high levels of sulfur and release nitrogen oxides upo

Shore power for liquid bulk vessels
Modelling of terminals and vessels for cost-effectiveness of different shore power systems
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 implem

Methanol Hybrid Offshore Working Vessels
A technical, environmental and economic assessment
To support Van Oord’s path towards a low-emission future fleet, this thesis has focused on the technical, environmental and economic impact of a methanol hybrid power plant design for new-build offshore working vessels (OWVs). These Dynamic-Positioning (DP) vessels are known for

Analyzing the economic benefit of fully electric autonomous vessel variants
Recommendation on operational conditions
Autonomous vessels carry the potential to increase the profitability of shipping companies. It is believed that an autonomous vessel design operates more efficient compared to a manned design. In this thesis the challenges of autonomous shipping and its consequences on ship desig

Green Refits
Reducing yacht operational emissions through refitting
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 t

Production Optimization
Introducing Quick Response Manufacturing to the Preprocessing Stage of Shipbuilding
This article aims at finding a match between Quick Response Manufacturing (QRM) and the preprocessing stage of shipbuilding. Preprocessing is the first stage of the ship production process, where steel plates are cut into parts, that are ground and sorted to build stiffened panel

Modular and future proof design of the energy storage and conversion system
A method development using Design Structure Matrix with the test case based on a Damen double ended ferry
Currently there is an energy transition from fossil fuels towards zero emission fuels within the marine sector. In addition to this, improvements are made in system design with regard to standardization of which allows for variation. The combination of these two improvements is f

3D motion compensation for an offshore crane
Assessing the feasibility for wind turbine maintenance
When working offshore on a floating vessel, the vessel will be subjected to wave induced motions and with a moving crane tip, a suspended load can start to swing. When the motions of the load become too large, the operation is interrupted. Alternatives such as jack-ups, function

Alternative marine energy carrier impact on ship powering and the environment
A comparative conceptual LCA of the operational stage of ship types with alternative marine energy carriers
This thesis investigates the total environmental impact of various alternative marine energy carriers while taking the powering increase into account due to their disadvantageous spatial requirements compared to conventional fuel. A parametric design tool for bulk carriers, tanke

Process improvement of Damen Shipyards Galati pre-processing
Merging two pre-processing facilities by implementing Lean Manufacturing
An improvement study to the pre-processing process of Damen Shipyards Galati (DSGa) is performed since benchmark analysis shows that the current pre-processing process underperforms, compared to industry peers. The objective is to increase DSGa’s throughput and decrease space uti

Including greenhouse gas emissions in a shipping company's decision making for the logistics of spare parts
A case study for chemical tankers
Shipping companies aim to reach the climate goals by following the rules from the International Maritime Oranization (IMO), which includes reducing Scope 3 emissions. Maintenance is a great contributor to the Scope 3 emissions of a shipping company, especially the transportation
