With increasing concerns surrounding environmental impact in the renewable energy sector, this study delves into the analysis of carbon dioxide (CO2) emissions generated by maritime logistics operations within Offshore Wind Farms.
Automatic Identification System (AIS) data is collected from Crew Transfer Vessels (CTVs). The primary objective is to quantify the environmental impact of these operations and, consequently, contribute to the development of sustainable solutions that can be alternatively used. Using data science and software tools, utilizing AIS data and Python, NumPy, Pandas, and the nautical-calculations library, the authors calculated the total CO2 emissions produced by the sample Crew Transfer Vessel. This CTV sailed 60,000 nautical miles over 5 years.
Additionally, the authors will explore the feasibility of integrating hybrid or electric CTVs to curtail the overall CO2 emissions associated with wind farm operations. These findings collectively offer a pathway towards a greener and more sustainable offshore wind farm operations.
By incorporating machine learning models in the future, the framework can enhance the efficiency of routes used by the CTV, leading to reduced fuel consumption and further minimizing environmental impact.
Moreover, the integration of hybrid or electric CTVs presents an opportunity to not only reduce CO2 emissions but also decrease reliance on fossil fuels in offshore wind farm operations. Ultimately, implementing these findings can contribute to a more environmentally friendly and sustainable use of CTV in the Offshore Wind industry.

Ferry traffic is particularly dominant in inland seas such as the Baltic Sea, where it can exploit its advantage of high departure frequency and short journey times, thus enabling fast-moving traffic throughout Europe. Roll on/Roll off (RoRo) and Roll on/Roll off Passenger (RoPax) ports, however, are confronted with increasing competition for port expansion areas from various developments such as the rezoning to urban areas. Therefore, maintaining adequate access to RoRo/RoPax ports is becoming increasingly challenging and can only be achieved through the interaction of different stakeholders such as port authorities, ferry companies or city planners. In urban areas in particular, traffic situations increasingly occur that make it difficult for trucks or other vehicles to reach the port reliably and thus place a heavy load on terminal and shipping company resources.
After analysing the literature on simulation approaches with respect to truck arrival management in the RoRo/RoPax and the container terminal segment, the application of a pre-gate concept to the RoPax port Turku (Finland) in combination with a call-off structure was analysed by a simulation.
In the paper three different scenarios were compared regarding the positioning of pre-gate parking spaces according to the parameters: travel time, vehicle arrival time at the terminal and queue length at a prominent intersection.
The approach adopted offers a controllability that can be actively used by the terminal operators and stevedoring to make terminal operations and vehicle handling more efficient.

Transporting goods via inland waterways offers significant advantages over transport via road or rail. The inland waterway vessel is more environmentally friendly, reliable, and quieter than other transport modalities. This paper presents a framework based on this motivation to develop so-called MicroPorts to strengthen inland waterway transport and increase its attractiveness. MicroPorts are new small-scale transshipment facilities for inland waterways based on the conversion of existing infrastructure. Through this, the network of transshipment points on inland waterways can be expanded while keeping construction costs and impact on nature low and the transported goods closer to their destination, shortening the last few kilometers by road or rail. The MicroPorts framework was developed through several workshops with an inland shipping owner, pro-cess analysis at an inland waterway port and literature analyses. It comprises five elements: characteristics, operational requirements, technical requirements, loca-tion, and assessment parameters. Based on the framework, a method was derived to develop MicroPorts. The method contains four steps: 1. Identify potential loca-tions, 2. Selection of possible operational concepts, 3. Selection of possible tech-nical implementations, and 4. Evaluation of feasibility. The method can be used for the identification of new transshipment locations and planning of new Mi-croPorts. This paper also presents first developed MicroPorts concepts alongside an exemplary route.
