Okeanis Eco Tankers Corp. (NYSE: ECO)

Okeanis Eco Tankers Corp. is an international owner and operator of a modern fuel efficient Eco fleet of tanker vessels focused on the transportation of crude oil. The company operates eight Suezmax tankers and eight VLCC tankers giving it a total carrying capacity of approximately 3.5 million deadweight tons and an average vessel age of about 6.4 years as of the end of 2025. Its vessels are equipped with scrubbers and ballast water treatment systems to meet environmental regulations.

Revenue is generated primarily by chartering its vessels under voyage time and bareboat arrangements and receiving freight payments from customers. The company also benefits from spot market charters when rates are favorable and from longer term time charters that provide more predictable cash flow.

Okeanis Eco Tankers Corp. competes with other crude oil tanker owners including independent operators and large publicly listed shipping companies. Its competitive advantage stems from a modern eco efficient fleet that consumes less fuel and is equipped with scrubbers which helps lower operating costs and ensures compliance with stringent environmental rules. The relatively young age of its vessels also positions it favorably against older tonnage in the market.

The company serves a diverse customer base that includes national regional and international oil companies trading houses and energy firms. While specific customer names are not disclosed the filing indicates that certain customers accounted for more than ten percent of revenue in recent years showing reliance on a few major charterers.
