The International Maritime Organization, the European Union Council and the US government force ship owners to take necessary measures through international conventions and national legislation to minimize ship-based emissions which damage to the environment and has reached a serious level. Thus, ship operators began to turn towards alternative technologies and fuels that reduce emissions to ensure the maritime trade smoothly. On the other hand, some port operators has started to supply alternative maritime power (AMP) which is electricity from city grid line to the ships at the berth. It is a fact that AMP is one of the best emission reduction alternative technologies for ships during berthing period. This kind of ports providing AMP will be compulsory choice for many ship operators who still use fossil fuel-powered engines in their ships and cannot meet the emission limit requirements at ports, also these ports will contribute to the environmental protection. In this study, AMP application will be examined for the Ege Ports in Kuşadası. Purpose of the study is to calculate the amount of emissions and external costs and to compare with marine gas oil (MGO) when the AMP system is applied to a port. According to comparison of AMP technology with MGO (0.1%S); total air pollutant is reduced by 94% via decreasing SO2 23%, NOx 97%, PM 88%, CO 99%, VOC 64%. On the other hand, it is estimated that total released greenhouse gases are minimized by 41% via decreasing CO2 41%, N2O 85% and CH4 81%. Finally, total emission reduction was about 43%. The economic and environmental benefits to the port hinterland and its country has been estimated by finding external cost. Total externality cost of MGO for human health, ecosystem quality and climate change was found as about Euro 3 million while Euro 0,4 million occured from AMP

Durumsal farkındalık, genel anlamda; hayatın her aşamasında etrafında neler olup bittiğinin farkında olup, algılanan bilgilerin o anda ve yakın geleceğe yansıtmak şeklinde tanımlanmaktadır. Çıkış alanı ilk olarak askeri havacılıkta olmuş, son 10 yıl içinde ise sivil havacılık, hava ve deniz trafik operatörleri, nükleer santraller, açık deniz sondaj çalışanları gibi operatör / kullanıcı temel merkezli; bilgisayar - yarı bilgisayar kaynaklı ve / veya amaca yönelik yardımcı sistemlerin kullanıldığı, karar vermenin ön planda olduğu alanlarda uygulanmıştır. Bu çalışmada, denizcilik endüstrisinin içinde bulunan liman kılavuzluk hizmetlerinde gemi kaptanları ve kılavuz kaptanların durumsal farkındalık analizi SAGAT yöntemiyle simülatör ortamında analiz edilmeye çalışılmış ve sonuçlar elde edilmiştir. Sonuçlar doğrultusunda durumsal farkındalık kavramının teknik seyir hizmetleri kalitesini arttıran öneriler de sunulmuştur

The rising importance of port-port user relations is a result of widening roles that ports play within the global supply chains and the increasing impact of these relations on the overall performance of the supply chains. In the governance of these relations, both contractual governance and relational governance play the role and the balance between these two governance mechanisms shapes the characteristics and the quality of the relationship. Focusing on the container terminal-liner shipping agency relations in Aliaga as multiple cases, this study aims to investigate how governance mechanisms are handled in the port industry and how the interplay between these two mechanisms occurs. In accordance with this purpose, interviews are conducted with both representatives of the container terminals and representatives of liner shipping agencies in order to reveal the governance dynamics of said relations. The results reveal that relational governance plays an important role in constituting trust and commitment in between parties. On the other hand, the tendency to rely on contractual governance is found out to be mainly related to the organizational culture of the parties, but relatively limited because of the intense competition in the region.
