Reducing air pollutant emissions and energy consumption, as a necessary step to make ports more sustainable, is one of the crucial tasks and challenges of port management. Some of the port strategies to meet the term “green port” usually include reducing fuel consumption from vessels and vehicles in ports. This paper estimates the emission inventory of maritime traffic for the cargo Port of Zadar. For this research, emissions from cargo ships are estimated in the period from January 01. 2018 until October 01. 2019. The “bottom-up” methodology has been applied for estimating emissions, which includes detailed data on the ship’s characteristics (engine power, the load factor, fuel type, the emission factor) and time spent cruising and hotelling. The emissions from cargo ships have been estimated for three ship’s activities: cruising in the reduced speed zone, hotelling (time spent at berth), and maneuvering. The emission results (tons/year) refer to the pollutants such as nitrogen oxides (NOx), sulphur oxides (SOx), particulate matter (PM), volatile organic compounds (VOC), and carbon dioxide (CO2) which represents greenhouse gases. Estimating emission inventory is the first step for planning effective port air quality control. Some recommendations for reducing emissions in port areas are emphasized in this paper.

Ship Inspection Report Programme (SIRE) addresses concerns about sub-standard shipping in oil industry. As a part of the risk assessment physical inspection of the oil tanker is performed by accredited SIRE inspector and resulting report is available to charterers, ship operators, terminal operators and government bodies. In this article SIRE inspection is described and compared with other non-mandatory and mandatory inspections on oil tankers. Some potential consequences of tanker over-inspections are discussed.

Despite the efforts of all stakeholders maritime accidents still occur, most commonly caused by human failure. Efficient team work is a vital tool in preventing occurrence or rectifying the errors and violations. Therefore Bridge Resource Management course focuses on developing and sustaining work teams. Unfortunately, team work can be hampered by many factors, including poor organisation, cultural differences, improper attitudes and behaviours, as shown by analysis of many accidents and it is important to address these issues during trainings. As a starting point for a discussion simulation training can be used. In this paper we propose three scenarios based on real accidents, which address problems that are usually not familiar to students: authority gradient, desire for harmony in a group and antagonism between specialties.

As a complex socio-technical system marine transportation is open to risks. Due to the efforts of international organisations, flag and port administrations, classification societies and ship-owners the safety record has steadily improved. However, marine accidents resulting from inadequate safety culture still occur. In this paper examples of recent accidents related to different dimensions of safety culture are provided. The role of the master in achieving an enhanced safety is emphasised.

Content available Interpenetrating polymer network composites containing polyurethanes designed for vibration damping

The paper is a literature review concerning the interpenetrating polymer network (IPN) composites containing polyurethanes that can be used for vibration damping in marine vehicles. The effects of filler introduction on damping, mechanical and thermal properties of IPN are compared. The addition of filler affects all relevant properties, in dependence on the filler type and quantity. Damping enhancement is achieved by introduction of each of studied fillers. The ability to optimize IPN structure and filler incorporation provides a way to obtain a material with desired features.

Artykuł stanowi przegląd literatury dotyczącej kompozytów poliuretanowych z wzajemnie przenikającą się siecią polimerową (IPN), wykorzystywanych do tłumienia drgań w pojazdach morskich. Porównano wpływ rodzaju ilości wprowadzonego napełniacza na właściwości tłumiące, mechaniczne i termiczne IPN. Stwierdzono, że dodatek każdego z omawianych napełniaczy poprawia właściwości tłumiące. Optymalizacja struktury IPN i wprowadzenie napełniacza umożliwia otrzymywanie materiałów o pożądanych właściwościach.
