Running costs include management expenses, salaries, fuel cost and maintenance. Operation
(rent, office, etc.) expenses foreseen as 1000$ per month, 2 office employees will be hired for
850$ per month salary. Also, salary of the captain assumed as 1200$ per month. Furthermore,
monthly maintenance fee foreseen as 1000$. Fuel cost calculation depends on the trip and its
specifications. For that reason, basic fuel consumption data calculated for further use in scenario
based estimation. Fuel prices were taken from up-to-date databases and are shown as U.S.
Dollar currency for decent comparison [11-13].

4. Results

Aim of this study is to design a vessel that can be an alternative for sea transportation of
Istanbul with its flexibility, speed and low construction and operation costs. Most of the design
parameters which are important to provide every specification for the outcome have been taken.
Detailed route analysis was carried out to understand the necessity for this product for Istanbul.
Different berths were examined to decide on the design restrictions. Different materials were
surveyed to resolve production cost as well as the aesthetic.

After the research phase concept and preliminary design stages were completed. Shortcomings
of the design were looked into. A rough cost estimation for production and a more detailed cost
estimation for operation were made for the vessel. As a result of this study, flexibility goal was
attained by vessel’s overmuch inner volume and its adjustable gangway. Additional, speed
target was reached by low displacement and planning hull form. Lastly, low-cost objective was
provided by less horsepower need and cost-efficient materials. Briefly, main technical goals of
this study were achieved.

On the other hand, design of the vessel exceedingly influenced by regulations and technical
requirements. Correspondingly, in an aesthetical aspect, vessel was not provided to get a desired
view. In future studies, enhanced structural calculations for manufacturing, detailed market
research, more professional cost estimation and completely new upper structure design can be
made in order to improve the current study. Consequently, despite some deficiencies, Chloris
concept can be an alternative vessel for Istanbul’s existing sea transportation systems.
