Objective: The aim of this study is to explicate the significant issues with regards to the suitability of the fuel consumed on board the ships, and in the meantime, to review its effects on two stroke slow speed diesel engines which are used as main engines on board.
Method: Shipboard records between 2007-2015 are reviewed through the study and data on Table 3 are gathered. 39000 hours of main engine piston and cylinder maintenance schedule is formed.
Findings: Post maintenance proper amount of lubricating oil is determined regarding the
suitable fuel and lubricating oil. Excel based lub oil calculation sheet is modelled by the input of load&sulfur content based data for the cylinder lubricating oils wich are adjustable in accordance with the variable sulfur content.
Conclusion: Same model can be applied to the engines with different type and tonnage and deficiencies can be stated and preparations can be made by extracting the engine maintenance history. For example, comsidering that piston maintenance was carried out 16 times through the 15000-19999 hours period, time can be saved by supplying the required spare parts in advance by anticipating the piston and liner replacements at the 35000-40000 hours interval of the second 20000 hours period after the first liner replacement. Major breakdowns can be prevented this way. Planned maintenance between the office and the vessel can become more efficiently. Study carried out in this context by evolving from real life applications, is aimed to be an inception for the future literature studies.

As known Kyoto Protocol forces the states to decrease carbon emissions due to the combustion of hydrocarbon content fuels in the energy plants. When current technologies have been investigated, it seems that there is no method that directly decreases carbon emissions. Nowadays, the most effective way for decreasing carbon emissions is to develop methods that increase the fuel efficiency of systems. In recent years international rules related to energy efficiency ships came into force.One of the components that consume energy in ships is HVAC (Heating, Ventilating and Air Conditioning refrigeration) system. In existing ships, refrigeration systems are designed to work under extreme conditions and compressors work at constant speed. In these systems, sea water is used as a coolant in condenser. When sea water temperature increases, the compressor outlet pressure must be kept higher in order to ensure condensation in condenser outlet. This situation causes increase in power demand of compressors which result in decrease of COP. On the other hand, when the sea water temperature decreases, the power demand of compressor decreases. In that case, itcannot be benefited from energy saving potential of refrigeration system occurred in lower sea water temperature conditions.
In this study, usage of variable speed compressors in refrigeration system is considered and a comparison of constant speed compressor system and variable speed compressor system is carried out. The condenser outlet temperature is utilized as main parameter for compressor speed adjustment and energy saving potential is calculated.

Studies on dry ports as nodes in multimodal transport have been expanded to decrease the mounting congestion on seaports. The principal objective of this study is to inspect how dry port researches have been conducted from different perspective. This paper tries to recap the existing researches that aimed to study dry port concept via a systematic review, to present a general overview of the researches on our relevant region and propose a classification for these researches. This paper present a systematic review of dry port that looks to illustrate the progress of researches on this area between 1986 and 2015, collecting researches on dry port concept and analyzing the main characteristics of the dry port development and their contribution to the multimodal transport. The results indicated that most dry port studies considerate the strategic level and concentrate in the Asian continent. Studies regarding other decision levels and continents have to be developed in further researches. Although the existing studies make a contribution in dry port concept, they allow gaps in terms of operational and tactical decision levels considering their limited geographical region.

Dry port-seaport services are key elements of a multimodal transport. They represent the needed infrastructure for its development. In this case, evaluating and improving their performance is necessary to achieve international competitiveness. The purpose of this paper is to develop a new model of performance measurement for the dry port-seaport system. To this aim, we have consolidated available researches and existing studies in order to identify and develop our proposed model framework. In this paper, a multi-criteria hierarchical model framework using MACBETH for dry port-seaport system has been developed. This framework can be used by managers at different levels of the system. The proposed model has been developed by exploring measurement gaps in
multimodal transport field and by discovering prospective options from this area. The results and the methodology are practical. We obtain the global performance level of our involved system using our methodology, which can help managers in taken decisions and increase global performance of this system.

Ports are the points where the countries meet the world and also one of the main facilities where transportation starts or continues in the trade process. As long as trade exist in the world, sea trade will also exist and to keep abreast of the times vessels will continue to grow, for this reason, ports will grow and continue to improve to serve better. The objective of this study is to calculate the containerised cargo demand for 2023, and to analyse if the container ports in Turkey will be able to handle increasing container cargo demand. Demand forecasting is significant for all the firms to see their future better and make appropriate plans. It is important especially for the ports to get an idea how much cargo they will handle next year. In order to serve increasing trade, ports have to forecast their cargo demand for future and make new investment or improvement plans. In this study, multi regression analysis is used to cargo demand forecasting of ports in Turkey. According to results current and planned container terminals in Turkey are already able to handle current demand and they will be able to handle increasing containerised cargo demand until 2023.

Ship loan credits used during the purchase of ships is considered to be long-term finance credits and their amounts are determined according to the valuation of the ship they are concerned with. The value of the ship determined at the time loan agreement is signed, goes under a “revaluation” process at the debt payment period. Even sometimes the “revaluation” methods mentioned in the bank loan agreements can bring beneficial opportunities to borrower shipping companies, they can also become serious financial threats in the long run. This is why a detailed and an accurate examination of the term “revaluation” is crucial when talking about the financial loan agreements. In this paper the possible financial threats within the valuation process of a ship is tried to be clarified within three different scenarios, with different examples. To be able to focus on the issue, financial terms such as “interest” and “commission” is not taken into the paper’s context.
