Diversely performing propellers as a consequence of design variability are nowadays a commonplace. Fundamental geometric particularities, including size, stipulate performance characteristics, which are usually the only required parameters when deciding on a propeller for specific purpose. With the main focus on the performance, accompanying phenomena, e.g. cavitation, tend to be overlooked. In this paper, propeller configurations in cavitating flow are investigated, with emphasis on real-world performance differences caused by cavitation. Recommended CFD approach is presented with respect to configuration specifics. Available experimental data is used as a baseline for a single propeller, which is then analysed in ducted and tandem configurations with resulting cavitation extents and shape evaluated in the context of current designs.

Emissions produced by the fuel combustion in marine engines are one of major causes of the marine environment pollution and have negative impact on both human health and the environment. That impact is more pronounced for vessels which mostly operate near ports and inhabited areas, such as ro-ro passenger ships. In order to evaluate the environmental impact of a ship, a life cycle assessment of a ro-ro passenger vessel operating in the Adriatic Sea has been performed. Two different power system designs were investigated, i.e. lithium-ion battery-driven vessel and diesel engine-driven vessel. The analyses were performed by means of general LCA software GREET 2018, where the life cycle for both power system designs is divided in two stages: constitutive parts of the first stage are processes from life cycle of fuel without its use in vessel, while vessel operation represents the second stage. The analysis showed that diesel engine-driven vessel emits 79.740 kg CO2-eq/nm, versus battery-driven vessel with 27.471 kg CO2-eq/nm.
船舶发动机燃料燃烧产生的排放物是造成海洋环境污染的主要原因之一，对人类健康和环境都有负面影响。对于那些主要在港口和居民区附近作业的船只，如滚装客船，这种影响更为明显。为了评估船舶对环境的影响，对在亚得里亚海运营的滚装客船进行了生命周期评估。研究了两种不同的动力系统设计，即锂离子电池驱动船舶和柴油机驱动船舶。分析是通过通用LCA软件GREET 2018进行的，其中两种电力系统设计的生命周期分为两个阶段:第一阶段的组成部分是燃料在船舶中不使用的生命周期过程，而船舶运行代表第二阶段。分析表明，柴油驱动的船舶排放79.740 kg co2当量/nm，而电池驱动的船舶排放27.471 kg co2当量/nm。

A larger cruise ship with more capacity enables the ship-owner to gain more profits while at the same time lowering the cost to the client. Cruise ships today have a capacity of about 5,000 passengers, and there are projects in development of cruise ships that will accommodate up to 10,000 passengers. Since such ships have to function as an independent and ecologically sustainable unit during navigation, there is a problem of waste management. This paper presents the methods and procedures for the disposal of liquid and solid waste on cruise ships in accordance with the applicable regulations. Furthermore, proposals for improving and adapting the MARPOL convention to the above trends are presented

Today the most crucial aspect in the preliminary vessel design stage is to make it as green/blue as possible. One of the exciting goals is the minimisation of vessel resistance. The use of hydrofoils to reduce the vessel draught and consequently, reduction in the vessel resistance is today one of the hottest design topics, especially for catamaran passenger vessels. In the present work, we discuss the issues related to the implementation of Isogeometric Analysis (IGA) Boundary Element Method (BEM) for the calculation of the hydrodynamic properties of lifting hydrofoils. The use of IGBEM allows numerical calculation of foil hydrodynamic properties without the traditional step of mesh generation using the CAD geometry directly. The analysis relies on the NURBS basis function with the generic Galerkin approach allowing identical solutions procedures for 2D or 3D problems. Method accuracy and computational times for a different number of Degrees of Freedom (DOF) in 2D are investigated.

Purpose – At a time of exceptionally fast technological advancement, smart cities have become necessary for the better management of existing resources in a tourist destination. The aim of this paper is to investigate if the smart city concept has been recognized in micro destinations in the Kvarner region for the purpose of sustainability and raising residents’ quality of life. Design/Methodology – The research has been conducted in the Kvarner tourist destination in December 2019. Citizens were asked their opinions within the scope of the following narrow tourist destinations – Lovran, Opatija and Rijeka. The questionnaire used closed-ended questions. This short research focuses on public perception regarding the smart city concept. Findings – The results show that 67% of the people living in tourist destinations are not familiar with the smart city concept. Most, however, state that its implementation would improve the touristic development of the destinations. The development of smart destinations leaves plenty of room for each community undertaking that step to define the shape and functionality of its environment while respecting the community’s historical, cultural-artistic and social heritage. Originality of the research – There are many papers dealing with the topic of smart cities, but it is rare for authors to explore the transformation of traditional tourist destinations into contemporary sustainable communities. The obtained results can be used to inform policy making towards becoming more proactive, smart and sustainable.

Environmental pollution is increasingly becoming a major global problem. Consequently, companies and policy makers are facing mounting pressure to reduce their impacts of logistics activities and make transport greener. The challenge to reduce the carbon intensity of maritime transport is even more important when we take into equation the fact that carries about 90% of the world trade. While car industry has already taken actions to greener cars, maritime industry is subject to fewer regulations and slower progress. This article overviews upcoming trends of green intermodal chains, initiatives in green maritime transport and how noteworthy is share of their impact in the transport chain as a whole. Speed reduction is one of most important measures which can be implemented right away with win-win impacting on environment and fuel cost. The study analysis environmental impacts of different services to eastern Adriatic ports, with special emphasis of slow steaming impacts on pollution level. The paper exposes that direct lines with bigger ships cause lower emissions of CO2, NOx and SOx and that with decisions of slow steaming the pollution level decreases significantly.

The Marine Strategy Framework Directive adopted in 2008 aims to achieve Good Environmental Status (GES) of the EU’s marine waters by 2020 and to protect the resource base upon which marinerelated economic and social activities depend. To that end each Member State is required to develop its Marine Strategy, keep it up-to-date and have it reviewed every 6 years. The Republic of Croatia has by mid-2019 not adopted its national strategic document. The paper analyses the chronology, content of EU official country reports on marine environment, possible obstacles in adoption procedure and presents proposal for more efficient approach to protecting the Adriatic Sea. Marine spatial planning is also considered key instrument for managing the conflicts resulting from the increasing utilization and industrialization of the world’s seas and oceans. The process of national marine policy adoption should be made more clear and transparent to general public which is at the same time the public concerned, and to expert community. Strategic vision can only be built on knowledge, education and awareness of wider public.

Merchant and passenger ships operate in harsh environments where they constantly suffer from corrosion and crack problems. The traditional cutting and welding of the steel parts most often requires redirection of a vessel to a shipyard what results in substantial vessel out-of-service time. In such situations, a ship operator seeks an efficient and fast repair solution to minimise ship delays. Following advancements in research and application of composite materials, an opportunity to implement composite patches made of carbon fibres and epoxy resin has emerged in the shipping industry as one of the cost and time efficient repair solutions. Although, the resin hardens and bonds the fibres strongly to the damaged surface, classification societies still consider this repair as a temporary solution and accept it conditionally, meaning with the frequent obligatory inspections. This is because there hasn’t been enough practical evidence yet to recognise the composite patching as the permanent repair solution. In order to further investigate the efficiency of the composite patching, this paper presents the finite element (FE) strength investigation of 17 patches applied to tube and tank specimens under water pressure. The future work will consider a validation of the obtained FE results by means of pressure testing during the course of the qualification process.
