Ship-Based Carbon Capture and Storage: A Supply Chain Feasibility Study

The International Maritime Organisation (IMO) calls for the maritime industry to restrict its CO2 emissions by −40% (IMO2030) and −70% (IMO2050). This paper answered the following research question: “Which technical, economic and emissions-related conditions predominantly determine the feasibility of a conceptual supply chain of liquid CO2 that...

Impact of SOFC Power Generation Plant on Carbon Intensity Index (CII) Calculation for Cruise Ships

The International Maritime Organization (IMO) has recently discussed the introduction of a new design index called the Carbon Intensity Indicator (CII), which is a measure of the total carbon dioxide emissions divided by the amount of cargo carried and by the distance travelled on a one-year basis. In this study, authors have analysed a cruise...

Variability in wave impacts: An experimental investigation

The prospect of stricter national and international emission standards for the shipping industry are a driving force in the search for alternative shipping fuels, such as liquefied natural gas (LNG). However, new challenges arise with the widespread use of LNG. For example, there is a desire to use LNG cargo containment...

Fuel consumption and emissions of ocean-going cargo ship with hybrid propulsion and different fuels over voyage

Hybrid propulsion and using liquefied natural gas (LNG) as the alternative fuel have been applied on automobiles and some small ships, but research investigating the fuel consumption and emissions over the total voyage of ocean-going cargo ships with a hybrid propulsion and different fuels is limited. This paper tries to fill the knowledge...

A Monte Carlo approach to the ship-centric Markov decision process for analyzing decisions over converting a containership to LNG power

A Monte Carlo approach to the ship-centric Markov decision process (SC-MDP) is presented for analyzing whether a container ship should convert to LNG power in the face of evolving Emission Control Area regulations. The SC-MDP model was originally developed as a means to analyze uncertain, sequential decision making problems. However, the...

Servicing the Arctic. Report 3: Design of an Arctic Offshore Supply Vessel (AMTSV)

Background To design a ship its specific design requirements are to be known. These are, together with class notations, specified in previous reports and extended in this report. Since the requirements are formed iteratively, design freedom is possible. This is used to implement several innovations into the design which improve the performance...

The sustainability of LNG evaporation

Numerous LNG (Liquefied Natural Gas) import terminals are under construction to fulfil the growing demand for energy carriers. After storage in tanks, the LNG needs to be heated and evaporated, also called ‘regasified’, to the natural gas needed in households and industry. Several options exist for providing the required heat. In the interest of...
