At MINOAN LINES, we view the environmental upgrading of our fleet as a fundamental prerequisite for a sustainable future in the coastal shipping sector. We consistently implement a comprehensive program of management and technological measures across our vessels—KNOSSOS PALACE, FESTOS PALACE, and KYDON PALACE—aimed at reducing fuel consumption and pollutant emissions, in pursuit of a "green" future. Our challenge lies in continuously shrinking the environmental footprint of our ships through ongoing upgrades, while simultaneously upholding the quality, high-level service, reliability, and operational excellence that define our company.
Since 2012, we have consistently pursued the technological upgrading of our fleet, alongside conservation measures such as the optimization of speed, vessel trim, and ballast management; improvements to propellers; and the application of silicone-based hull coatings—all designed to enhance energy efficiency. In 2018, we initiated the second phase of propeller blade optimization, with completion scheduled for 2024.
In 2019, leading the way in environmental compliance, we became the first company in the Greek coastal shipping sector to invest in exhaust gas cleaning systems (scrubbers)—well ahead of the implementation of the relevant International Maritime Organization (IMO) regulations—achieving an overall reduction in SOx emissions of approximately 97%. Our vessels’ emissions are certified and fully compliant with the requirements for ECAs (Emission Control Areas), where stricter controls and conditions are imposed to reduce air pollution from ships.
In 2025, we upgraded the fuel injection pumps of our electrical generators to feature variable injection timing technology. This reduced the generation of particulate matter during low-load operations, while also lowering annual fuel consumption and CO2 emissions by 2%. Concurrently, we upgraded the burners on our steam-generating boilers, resulting in a 5–7% reduction in their annual fuel consumption. Overall, these measures have led to a reduction in fuel consumption and CO2 emissions of approximately 26% over the 2008–2026 period.
Energy efficiency upgrades are complemented by the replacement of 85–95% of conventional lighting with LED, alongside protocols for managing plastic waste. To conserve water, we have implemented flow restrictors and plumbing system improvements, while also raising awareness among passengers and staff. By the end of 2026, our entire corporate fleet will consist of mild-hybrid, plug-in hybrid, and electric vehicles, facilitating a transition toward a cleaner model of mobility.
We regularly evaluate our progress to ensure we remain aligned with a unified sustainable development framework, driving the shift toward a modern, efficient, innovative, and technologically responsible shipping industry.
