... This paper presents the measurement techniques deployed by the European funded SCIPPER project in order to identify their potential in assisting regulatory authorities to enforce the new emission limits for shipping. On-board sensors, sniffer remote and remote optical devices were extensively...

... Union (EU) introduces regulations and initiatives to accelerate the transition. Each decarbonisation effort should be closely examined both in terms of emissions and cost in order to prove its benefits to the environment and ship owner, respectively. Uncertainties should be carefully considered...

... Shipping operates in a challenging economic environment characterized among other by increasing environmental regulations aiming to contribute to the global GHG emissions reduction targets set. Smart monitoring tools are key solutions for shipping companies to adapt effectively and comply...

... by potential flow calculations. A series of promising design alternatives derived by the optimization study have been re-evaluated by more accurate viscous flow calculations. Finally, the best performing hullforms are tank-tested at the towing tank of NTUA’s Ship and Marine Hydrodynamics Laboratory...

... Τhis paper presents the major steps of designing the electric energy system of a ship, the main power units of which are electric batteries. Moreover, the paper is concentrated on discussing and highlighting critical aspects, to which attention must be paid, like criteria of selecting battery...

... in the Stavanger/Norway area in late September 2022. The prototype character of MS Medstraum led to its selection as “Ship of the Year 2022” at the major international maritime exhibition SMM 2022 (September 2022, Hamburg). The presented research is in the frame of the H2020 funded project “TrAM – Transport...

... From 2023, commercial ships must report their actual annual Carbon Intensity Indicator (CII), which will have to be verified against the required annual CII; the latter will become progressively stricter with time - a significant challenge for the maritime sector. The main objective...

... Anthropogenic Greenhouse gas emissions increase rapidly throughout years, forcing International Maritime Organization (IMO) to set strict targets on reducing emission in shipping. Carbon Capture (CC) could be one of the solutions within the decarbonization spectrum, given its potential...

The basis of any approach to operational optimization is a digital twin which allows predicting the behavior of the ship and its energy consuming systems in a reliable and suitably accurate way. Here geometry plays an important...
