[3]
3 BACKGROUND
Implementing floating fuel stations has become an
effective solution to address the challenge of limited
fuel availability in seaports. By providing a
sustainable and dependable fuel supply for maritime
vessels, these stations significantly reduce the risk of
fuel shortages. This enhances smooth operations and
optimizes Port efficiency, benefiting both the Port and
the vessels.
Furthermore, floating fuel stations offer flexibility
in location. Unlike fixed fuel stations confined to
specific Port areas, floating stations can be positioned
strategically according to Port requirements. This
facilitates a more efficient fuel supply distribution and
minimizes congestion at designated refueling points.
[4]
Additionally, floating fuel stations boast a larger

Studies conducted by organizations such as the
World Bank and the International Association of Ports
and Harbors (IAPH) highlight the substantial benefits
of floating fuel stations. A World Bank study found
that average vessel turnaround time can be reduced
by up to 8 hours, with floating stations eliminating the
time spent on refueling. The IAPH research indicates
that these stations can decrease turnaround times by
as much as 30%, leading to substantial cost savings for
shipping companies and increased revenue for the
port.
Furthermore, floating fuel stations offer cost
savings for both port operators and vessel owners.
Traditional methods of refueling, involving bunker
barges, are often expensive. Floating stations provide
a more economical alternative due to their lower
operational costs. Additionally, having fuel readily
available within the port eliminates the need for ships
to carry extra fuel, reducing vessel weight and

7 LITERATURE REVIEW
In recent years, floating fuel stations have emerged as
a popular topic of conversation, with the potential to
significantly improve the efficiency of port operations.
Research by Lee et al. suggests that the use of floating
fuel stations can save ships up to 24 hours of berthing
time, resulting in cost savings and enhanced
performance. Additionally, these stations can reduce
the number of vessels waiting in line for fuel, thereby
decreasing congestion and delays. [14]
A successful example of the implementation of
floating fuel stations can be seen at the Port of
Rotterdam, the largest port in Europe. By providing
ships with various fuel options, including LNG,
diesel, and marine gas oil, the port has significantly
reduced refueling time and expenses, leading to
increased productivity.
However, implementing floating fuel stations at
seaports presents several challenges. One major
obstacle is the need for specialized infrastructure and
technology to support the operations of these stations,
as highlighted by Li et al. The installation of floating

Despite these obstacles, floating fuel stations offer
numerous benefits for the maritime industry. They
offer a convenient and efficient way to refuel ships,
eliminating the need for lengthy trips to other ports.
This significantly reduces refueling time and costs,
ultimately contributing to a more efficient and
environmentally friendly shipping industry.
A 2016 report by the International Maritime
Organization (IMO) highlighted the potential of
floating fuel stations to reduce the shipping industry's
emissions by up to 18%. Further research conducted
by the Saudi Ports Authority in 2018 revealed that
ships at Saudi ports typically wait an average of 12
hours for refueling. This waiting period not only
increases operational costs for shipping companies
but also hampers port efficiency and productivity.
Floating fuel stations can significantly reduce this wait
time, leading to increased port productivity and
overall efficiency in the maritime sector.

step is to analyze data to identify trends in average
waiting times for ships before and after their
implementation. This analysis will utilize a line graph
and linear regression to establish a baseline for further
investigations. By examining these trends, we can
determine potential improvements in ship waiting
times.
14 MULTIPLE REGRESSION EQUATION
Following a baseline analysis, a multiple regression
model will be developed to explore the relationships
and dependencies between identified variables,
including the port productivity index, measured in
TEUs (Twenty-foot Equivalent Units). This model will
be rigorously tested using statistical software to
determine its significance and effectiveness in
predicting port efficiency. The primary objective is to
evaluate the impact of floating fuel stations on
reducing ship waiting times and improving overall
port efficiency. The statistical analysis will provide
crucial insights into the potential benefits and

14.1 Results and Discussion
Analysis revealed that the number of ships visiting
had a strong positive impact on port productivity,
with a coefficient of 10.5. This suggests that for each
additional ship, the port productivity index increased
by 10.5 units.
14.2 Regression analysis further determined the following
relationships:
− Number of floating fuel stations: A positive
correlation (coefficient of 15.2) indicates that for
each additional floating fuel station, the port
productivity index increased by 15.2 units. This
aligns with previous research on the positive
impact of fuel stations on port efficiency.
− Average waiting time for ships: A negative
correlation (coefficient of -0.8) shows that for each
hour of increased waiting time, the port
productivity index decreased by 0.8 units. This
highlights the importance of minimizing ship
waiting time to maintain high port productivity.
The study found a strong positive correlation
between the number of ships visiting Saudi ports and
port productivity, with a coefficient of 10.5. This
indicates that for every additional ship, the port
