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 ...
Nowadays the interest for environmental issues is steadily gaining ground. Inescapably, the shipping industry, is also called to contribute its fair share towards the reduction of air pollution. Harbour tugboats need to comply both with international but also with local exhaust a ...

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 ...
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 ...
Ballast water, routinely taken on by ships for stability and structural integrity can contain thousands of mi- crobes, algae and animals. When discharging this ballast water holding these organisms in a non-native ecosystem, new invasive aquatic species can be introduced. This ca ...

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 (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 ...
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 ...
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 ...

Towards a Roadmap of IHC IQIP

Oil & Gas Market Analysis

To plot the roadmap for the oil & gas sector, it is essential to do the market demand analysis and research the influencing mechanism of oil price on the offshore projects market and offshore equipment market. The equipment market of IHC IQIP is primarily the market of offshore s ...
