Abstract
The main purpose of this thesis is to investigate the cost structure, green shipping
practices and digital transformation of Olympia Ocean Carriers conducting a case
study. The results showed that there is strong seasonality in the company's costs. More
specifically, shipping costs for ship spare parts were particularly high in the period
August-November of 2022. Additionally, popular countries suppling Olympia Ocean
Carriers with spare parts were Japan, the Netherlands and Korea. On the other hand,
important shipping countries were China, Singapore and Egypt. These countries are
many miles apart underlying the need to implement green shipping initiatives to reduce
the company's environmental footprint.
In terms of cost per vessel, it was found that Capesize vessels conduct the majority of
transportations, intensely contributing to the company’s total transport costs. Moreover,
it was found that Olympia Ocean Carriers uses alternative forms of fuel, such as
liquefied natural gas, in some of its ships. Additional green initiatives that have been
implemented are ship speed optimization, hull coatings and idle time reductions. In
addition, the company has embedded digital sensors in its commercial fleet, which
heavily rely on big data to transmit a variety of digital information. Such information
is collected in real time and concerns the temperature inside the containers, the outside
atmosphere, weather conditions, as well as the exact location of both ships and
containers. At the same time, it was found that the company has taken significant steps
in terms of digital transformation using new technologies such as digital blockchain,
5G network and artificial intelligence. Finally, based on the results, strategic proposals
are made for professionals and researchers in the field of marine logistics.
