Project

AquaBuoy is a buoy that can convert energy in ocean waves into electricity. AquaBuOY consists of a 9m high float with a diameter of 6m, under which is fixed a 25m long vertical tube with an inner diameter of 4m. AquaBuOY is designed to have large vertical movements in relatively small buoys. By mounting a special hose pump inside the long vertical tube, the wave energy can be extracted by utilizing the differential movements between the vertical tube and the water column inside the tube. The project primarily deals with the design and dimensioning of the anchoring system. AquaBuOY is being developed in collaboration with AquaEnergy Group, USA and Rambøll.

The project concerns consultancy in connection with the construction of a new wave laboratory in Naples, Italy. The Department of Water, Soil and Environmental Engineering comments on the design and supplies software for data analysis and control of the wave machines. The project has been carried out for the 2nd University of Naples, Italy. (Peter Frigaard, Palle Meinert, Thomas Lykke Andersen)

The primary goal of the project is to develop and make available data from Dansk Søfartstidende. The project has a particular focus on ship dispatches published in Dansk Søfartstidende in the years 1893-1962, and involves scanning, automated analysis and interpretation of data regarding Danish ships on arrivals and departures as well as other incidents for which notes are available. In addition to making the resulting data available so that they can be integrated into standard tools for representing digitized data, the plan is to develop a dedicated application that supports searches aimed at special studies based on, for example, time, place and context.

The project's results in the form of a database and dedicated search application primarily provide new opportunities for research, among other things, by virtue of the fact that individual ships or a shipping company's entire fleet can be followed and analyzed in time and space. Furthermore, new uses of maps and data visualizations in the dissemination of Danish maritime history are enabled. Finally, the project will make the complete publications of the Danish Maritime Journal available to the general public in a clear and easily accessible form through the M/S Maritime Museum.

Vessel propellers have reduced power efficiency with increased growth of barnacles and fouling, leading to an

increase in fuel consumption as high as 5%. SubBlue Robotics has developed an underwater propeller po-
lishing robot that allows for propeller polishing without the use of divers, and is capable of careful, precisepolishing of curved surfaces. As no divers are in the water, it can polish when the ship is loading and unloading

cargo, thus saving the shipowner valuable idling. Idling is the reason why the propeller polishing is often skip-
ped. The project will give technical robustness to the existing prototype, develop commercial grade components, and test the robot on commercial vessels. Leading partner is SubBlue Robotics, who has worked on

the designs and prototypes since 2016, the MMMI now IME institute at SDU provides knowledge on robots in harsh

enviroments, while shipowners DFDS and Maersk and diving company Odin Diving represent the market de-
mands the robot must meet. Three senior executives from CoGrow have invested in SubBlue Robotics, who

has just secured yet more capital and competences from two more investors.

Abstract:
The worldwide climate change is caused by the increased greenhouse gas (GHG) concentration in the atmosphere. To achevie the Paris Agreements 1.5 °C pathway the GHG carbon dioixde (CO2) must be reduced. Therefore according to the UN’s Climate Panel IPCC, a crucial tool to achieving the Paris Agreement is Carbon Capture, Utilisation and Storage (CCUS) which would be challenging to achieve without. CCUS is a technology where the CO2 emissions are reduced by capturing the CO2 and storing it in a geological site or utilising it for green fuel production. However, the CO2 cannot be stored or utilised if there is no connection between the capture site and the storage or utilisation site. Three primary forms of transportation are by trucks, ships or through pipelines. Pipeline transportation is the main way of transporting CO2. However, impurities like H2O, H2S, NOx, and SOx can compromise the transportation and cause corrosion or scaling, leading to huge economic costs, underlining the need for proper pipeline material selection and monitoring of these impurities. Furthermore, it is desired to limit the need for purification of the CO2 without having the risk of corrosion, becoming a cost balance between material and purification cost.
This PhD project will study the material integrity of the Carbon Capture Storage transportation infrastructure, focusing on the impurities and their negative impacts on the transportation infrastructure. Additionally, measure corrosion and monitor the impurities inside the CO2 transport pipeline.
