Filing Explained

The Form 6-K furnishes the July 30, 2026 vessel update as interim material information and incorporates it by reference into two Form F-3 registration statements declared effective on May 21, 2025, adding the update to those registration-statement disclosure records.

Incident date July 30, 2026 Date Nissos Sifnos was hit by a drone while loading crude
Suezmax tankers in fleet 10 vessels Modern scrubber-fitted Suezmax tankers in the sailing fleet
VLCC tankers in fleet 8 vessels Modern scrubber-fitted VLCC tankers in the sailing fleet
Incorporation date April 30, 2018 Date Okeanis Eco Tankers was incorporated in the Marshall Islands
Suezmax technical
"The sailing fleet consists of ten modern scrubber-fitted Suezmax tankers"
Suezmax is the classification for the largest oil tanker size that can pass through the Suez Canal fully loaded; think of it as the biggest truck that still fits down a narrow highway. It matters to investors because ship size influences shipping costs, route choices and supply-chain flexibility — factors that affect oil transport expenses, freight rates and the profitability of energy and shipping companies.
VLCC technical
"and eight modern scrubber-fitted VLCC tankers"
A VLCC is a very large crude carrier — one of the biggest types of oil tankers used to move crude oil across oceans. Think of it as a giant delivery truck on water that carries millions of gallons of raw oil between producing regions and refineries; changes in how many VLCCs are available or how much it costs to operate them can affect shipping rates, oil supply flows and margins, and therefore the revenues and valuations of energy and shipping companies.
Caspian Pipeline Consortium (CPC) terminal technical
"loading Kazakh origin crude at the Caspian Pipeline Consortium (CPC) terminal"
forward-looking statements regulatory
"This communication contains forward-looking statements, including as defined under U.S. federal securities laws"
Forward-looking statements are predictions or plans that companies share about what they expect to happen in the future, like estimating sales or profits. They matter because they help investors understand a company's outlook, but since they are based on guesses and assumptions, they can sometimes be wrong.
Norwegian Securities Trading Act regulatory
"subject to the disclosure requirements pursuant to Section 5-12 of the Norwegian Securities Trading Act"
The Norwegian Securities Trading Act is the national law that sets the rules for buying, selling and offering financial instruments in Norway, including requirements for fair disclosure, market conduct and investor protection. For investors it matters because it helps ensure companies and intermediaries provide accurate information and prevents abusive trading, much like traffic laws make driving safer and predictable so people can trust the market and make informed decisions.
