Requirements for Cargo Features on New Parcel Tankers
A Study for Stolt Tankers
Stolt tankers is the largest operator of deep-sea chemical parcel tankers. Parcel tankers differentiate form bulk chemical tankers by the additional features that the ships have, such as cargo cooling, cargo heating, many (small) cargo tanks, highest level of chemica

Maintenance and Repair
A Maintenance and Repair Management Performance Model for Tugs
Maritime transport covers about 90%of world trade and is seen as one of the most cost-effective way of transporting
goods. In order to safely accommodate vessels calling into ports, tugs are operated to assist various
sized vessels with navigating, manoeuvring and berthing. Compe

A comparison between the ’Smart-Stabiliser’ and a wider ship
The case of Jumbo Maritime
Jumbo Maritime is a shipping company active in the heavy lifting market. Jumbo uses stabilisers to enlarge the stability of the ship during lifting. By using stabilisers Jumbo can perform heavy lifts with a relative small ship, this is one of the major advantages. Downside of usi

Vessel's Performance Modelling
Developing a digital twin for the propulsion system, a Spliethoff group case
In this thesis, it was examined how high-frequency operational data collected from an automated recording system, can be used to develop a vessel’s performance model. Both the traditional and the Machine Learning (ML) approach were examined. In the traditional approach, every com

Energy Efficiency - The Data-driven Decision Support System Perspective
A Case Study About Long Distance Towage for Boskalis
The data-driven decision support system gives a competitive advantage by the cost-effective improvement of the fleet’s energy efficiency and by the controlled compliance with the IMO Greenhouse Gas Reduction Strategy. The conceptual Business Intelligence Design provides the found

Factors affecting container transshipment volumes at ports:
A data driven holistic modelling approach
In 20 years, from 1996 to 2016, global cumulative container port throughput had an average annual growth rate of 6.3%. Furthermore, the average global transshipment incidence increased from 11% in 1980 to a stable 27% in 2017. This change in transshipment market dynamics has led

Using container flows to predict economic activity
An application to transpacific trade
There is a significant historical link between maritime trade and economic activity. With the rapid growth of containerised trade over the past 60 years, a significant share of global trade is transported by container nowadays. This suggests there is a connection between containe

Battery boat
Concept study in bulk electric energy sea transport
Developments in the field of renewable energy technologies have lead to low energy cost in areas with specific characteristics. In the Middle East solar power plants are built for prices around 3 cent per kilowatt-hour and bids below 3 cent have been placed. In Europe wind energy

Wing in ground vehicles operating as high-speed passenger ferries
A feasibility and profitability study
Wing-in-ground (hereafter referred to as WIG) vehicles operate a few meters above water. The vehicles make use of the ground-effect (an effect where the drag is reduced, and the wings of the vehicles generate an increased lift). The unique speed and distance range of a WIG vehicl

Short term predictive demand model based on transport times for the reverse supply chain
A case study at KLM Engineering & Maintenance Component Services 2.0
The aviation Maintenance, Repair and Overhaul (MRO) industry faces an enormous growth due to the increasing air traffic. To accommodate this growth and increase efficiencies of processes it is required to increase the transparency of demand in the Supply Chain (SC). Research into

Maritime fuels of the future
A decision support tool for shipowners
This study aims to develop a decision support tool which enables shipowners to select the most appropriate alternative fuel technology to comply with possible different imposed emission regulations while ensuring optimal business performance. In this context, most appropriate is

Evaluating the potential of a mobile shiprepair facility
A feasibility study in the conceptual phase
Setting up or dismantling a shiprepair yard requires vast amounts of time and resources. Current shiprepair yards are land-based facilities that can not be moved when demand for their services declines. A mobile shiprepair facility would be able to and Damen Shiprepair & Conversi

Ship Performance Management and the added value of a Ship Performance Monitoring System
A Spliethoff Group Case
Harsh market conditions make optimising the performance in shipping more and more important. Shipping companies are becoming more and more data driven due to developments in data systems and these harsh market conditions. The goal of this research is to determine how and how much

Simulation of a Proactive Planning Strategy at a Tank Storage Terminal
A Case Study at Vopak Terminal Amsterdam Westpoort
The growing pressure on tank storage terminals is pushing the terminals to find ways to accommodate more vessels by increasing the efficiency of the vessel handling process. This research looks at the possibility of implementing forward planning at such a terminal by simulating m

Turning a problem into value
The case of plastic reaching the ocean
Economies are rapidly growing. Production and consumption rates are higher than ever before. And the disposal rates are increasing with it, with the absence of any waste infrastructure that can suffice. Global pollution has turned into one of today’s biggest threats for the envir

A decision-support method to meet the emission standards in shipping
The case of Seatrade
Due to the increased social importance and regulations on shipping emissions, effort must be made by shipowners, operators and naval architects to reduce the amount of air emissions from ships. A large set of emission control methods exists, but compatibility and interaction issu

Inland Shipping & Container Handling
Feasibility study on scalable inland container transport and terminal concepts
Small scale inland shipping, especially in the case of transported containers, is used only marginally compared to its capacity. The small inland waterways have abundant capacity to accommodate up to 700 percent more transport. On the other hand, road based container transport is
