“…The goal is to establish an acceptable safety and reliability level by using the risk control option in determining the acceptable threshold of the air pollution concentration. The cost-benefit analysis is performed based on the total expected risk, Risk t (x), which is a product of the probability of failure and consequence cost [35,42]:…”

This work develops a stochastic air quality dispersion to predict the pollution concentration originating from ships queuing in a seaport. The Gaussian dispersion model for five ships operating in the Black Sea queuing in the front of the port of Varna as sources of gas emission of NOx, SOx and PM10 is used to define the air pollution concentration at receptors (crowded areas of the port and other reference points) and consequently the distance to the seaport queuing location. Uncertainties, which are inherent in the input data and mathematical model, are accounted for to estimate the propagating uncertainties of the emission concentration at the receptors accounting for the wind speed, horizontal and vertical dispersion parameters as a function of the geographical location of the emission sources (ships), effective emission height and weather conditions. The estimated uncertainties of the air quality prediction are of significant importance for the decision-making on the regulatory purposes, and the probability of exceeding the threshold limits needs to be quantified. The most expected value and the probability of exceeding the acceptable limits of pollution concentration are defined by employing the first-order reliability method. The target reliability level is defined as the failure cause and mode used for identifying the safety calibration factors that may be employed for defining the most suitable location of the ship queuing seaport. Several conclusions about the applicability of the developed stochastic model and its use for regulatory purposes are also provided.

“…The concept design parametric model developed in [18] was employed to define parametric models for the visibility, free-board [28], initial stability [29], bow and stern design [29,30], resistance and propulsion [31], propeller system engine match [32], control and manoeuvrability [33], seakeeping [34], strength [35] and energy efficiency index [36].…”

“…Accounting for the risk involved in the ship operation, a risk-based conceptual ship design framework for bulk carriers was developed in [18] while considering the ship propulsion system, life-cycle assessment, and energy efficiency and including the conceptual ship design as part of the risk-based ship design approach. The conceptual design was based on long-term experience and statistics related to the main dimensions and hull form, resistance and propulsion, weights, initial stability, free-board, seakeeping and manoeuvrability, capital, operational, and decommissioning expenditure.…”

Integrating innovative solutions for ship design has always been a great challenge for the maritime sector due to complex design and construction processes. With this scenario in mind, the objective of this study was to develop a procedure to evaluate the potential benefits arising from the integration of innovative light-weight structures in ship hull structural design. To achieve such an objective, a hybrid light-weight ship hull structural design solution, in which aluminium honeycomb sandwich panels were used to build the conventional steel inner side shell of the cargo holds, was adopted for a bulk carrier. The authors of this study used a multiple criteria decision-making approach. An optimal ship hull structural design solution was identified based on capital cost, voyage cost, annual cost, energy efficiency design index, dismantling–reselling cost, cargo transportation, energy consumption and carbon footprint. The optimal solution, identified with the multiple criteria decision-making approach, improved the ship’s efficiency and costs by combining the hybrid structural design with efficient cargo transportation. In addition, using recycled aluminium was found to be a promising strategy to reduce the energy consumption and carbon footprint related to the shipbuilding process.

This work analyses the operational characteristics, including the fuel consumption and carbon emissions of self-reported data of container vessels performing regular short sea voyages in the Black Sea. The data are extracted from the EMSA THETIS-MRV database covering the period of 2018–2021. The main particulars of container ships that visited six Black Sea ports were collected from the Marine Traffic platform and Equasis database. Several conclusions about the status of carbon emissions from container shipping in the Black Sea are presented, which may support the short shipping companies in developing measures to incentivise decarbonisation in the region. It has been identified that the correlation between ship deadweight and total fuel consumption and CO2 emissions is weaker than the correlation between distance travelled and transport work. The decrease in CO2 emissions in 2021 can be attributed to reduced ship activity and emission-reduction measures. The ratios of CO2-related indicators to ship deadweight are more diminutive, showing a lack of correlation. An approach based on the confidence ellipses is employed in performing an innovative analysis of the CO2 emissions over the years for container ships operating in the Black Sea. This is important due to the new requests for using EEXI and CII.
