The digital and energy transition will change our industry. To be prepared for this challenge, NHL Stenden University of Applied Sciences puts quite some effort in developing new innovative courses and new types of digitally enabled education. An example is a new minor concentrated on engineering tools and methods that have emerged in the (construction) industry over the past decades. In addition, the school is also working on a game to educate an old trade: ship stability. In addition to the changes to the existing programs, a new level of education is introduced in the Netherlands, the Professional Doctorate. The Professional Doctorate is comparable to the PhD but focusses on practically applied research. All these changes and innovations to the current maritime education at NHL Stenden are elaborated upon in this paper. The paper concludes with an outlook to the future, based upon the results from a survey held under students and lecturers regarding their view on the future of maritime education. The results of this survey show that especially green and modern propulsion methods are underexposed in the current curriculum. ...
Conference paper (2022) - Carmen Kooij
The research effort into unmanned and autonomous ships has increased significantly over the last decade. Although not all required technology is currently commercially available, consensus is that from a technical standpoint, unmanned shipping is possible. The next question is: is it economically feasible to operate an unmanned ship. The article investigates which operation parameters influence the economic feasibility of differently sized unmanned ships the most. ...

A task based design process to identify economically viable low and unmanned ship concepts

Doctoral thesis (2021) - C. Kooij
Unmanned and low-manned transport has increasingly been studied this past decade. While there have been successful trials for autonomous navigation, unmanned cargo ships are not commercially available yet. First, this dissertation investigates how changes to a ship’s systems and organizational structure can affect the crew’s size and composition. Then, a cost benefit analysis determines the economic viability of these concepts. This research concludes with feasible intermediate steps between a conventional ship and a fully unmanned ship. ...

While successful trials for autonomously navigating ships have been conducted, commercially available unmanned cargo ships are currently unavailable. However, there are many solutions available that will allow for low-manned ship concepts long before fully unmanned ships are possible. There are many drivers for low-manned and unmanned shipping, ranging from availability of workforce, to increased safety to economic. This article investigates the economic viability of several low-manned ship concepts as well as the unmanned ship concept for a short sea container vessel. The operating cost of these concepts are compared to those of a conventional vessel. That way, an assessment can be made on the economic viability. The results show that the low-manned concepts investigated in this article are worthwhile for the ship owner, as some savings can be achieved. The economic viability of the unmanned concept is dependent on the chosen type of propulsion. ...

Autonomous and unmanned shipping are currently hot topics in the maritime industry. However, there are many different views on how the ultimate goal of an unmanned, autonomous ship will be reached. On any given ship, a large range of tasks is performed every day, each of which need to be replaced in such a way that no human presence is required on board. In this article, different possible combinations of tasks to be replaced are explored systematically, leading to an overview of the most beneficial combinations of tasks to replace together and a logical sequence in which to replace them. This leads to a plausible implementation path from low-manned ships towards fully unmanned autonomous ships. ...

Recently, autonomous ships have gotten a lot more attention both in the media and in research. However, very little research has focussed on the effects of automation on the size of the crew. This paper analyses the effects of added automation on the required size and composition of the crew on a 750 TEU short sea container vessel. A Crew Analysis Algorithm is used to determine the cheapest crew composition to perform the tasks required to operate a ship. Using this algorithm, two potential automation options are investigated: automating the navigation tasks and automating the mooring tasks. Automating the navigation tasks decreases the required crew size in the normal sailing and arrival & departure phases by 3 and 1 crew members, respectively. The loading & unloading phase is unaffected. Automating the mooring tasks reduces the required crew in the arrival & departure phase to 2. It is concluded that since individual automation options do not affect the crew requirements for all travel phases, their effect on crew reduction is limited unless several options are combined. However, with a change in task assignment and different training of crew members, a reduction of the required number of crew members is possible. ...

The effects of automating navigational tasks on crewing levels

Conference paper (2019) - Carmen Kooij, Robert Hekkenberg
This paper presents a method to analyse the required crew composition on board of a short sea cargo vessel. By using a purpose-built tool it is possible to assign all tasks on board to the most appropriate crew member. This tool is used to analyse the changes to crew composition when the navigational tasks on board of the ship are removed from the workload of the crew. The analysis shows that during the normal sailing and arrival and departure phase, this results in a decrease of the required crew size of respectively 3 and 1 crew members. This reduction can, however, only be realised if the procedures during the loading and unloading phase are changed too, since this is the normative phase of the voyage for the crew size. ...

Operational challenges of unmanned short sea cargo vessels

Autonomous shipping is considered a highly promising development in the shipping industry. Technologically it is believed to be possible, but there are several challenges that still need to be solved before autonomous shipping can become a reality. In this paper the main challenges for autonomous shipping are identified. This is done by taking the main functions of the ship and combining them with the crew tasks. That way it is possible to identify where problems occur when the crew is no longer on board. Combining the challenges found with prior research on autonomous shipping leads to three elements into which little to no research has been conducted. However, they are important for the operation of an autonomous ship. The elements that need to be further investigated are; navigation and situational awareness, ship-to-ship communication, physical intervention of the crew on the ship and its systems, and maintenance and repair. ...

A technological forecasting perspective

Conference paper (2018) - Carmen Kooij, Alina Colling, Chris Benson
Autonomous ships have received significant attention in recent years. However, they are not yet widely adopted in the maritime industry yet. A wide range of predictions have been made about when the technological change will occur. This paper analyses technologies that are critical to autonomous shipping and forecasts a range of times when they will reach technical and economic viability. The researched technologies include data transfer, navigation, cargo handling, fuel cells and diesel engines. The results indicate that the GPS navigation precision required for autonomous shipping is not yet technically feasible and the expected feasibility time frame is between 2030 and 2058. The remaining technologies all show technological feasibility, but not yet economic viability. The forecasted range for economic viability of data transfer is a narrow range of 2024-2025, while cost of automated cargo handling will reach the current expense levels somewhere between 2036 and 2101. ...
