Which issuers SuperRonin reads, and a circulars screen on the front page
27 Oct 2026
The open circulars index answered "what did this issuer publish". People kept asking a different question: which issuers do you actually read, and what about mine? The answer used to be scattered across a FAQ line and the issuer pages. Now it has a page of its own at superronin.com/circulars/sources.
What's on it. The page lists issuers by kind: flag administrations, classification societies, P&I clubs, port State control regimes and the IMO. For each one we read, a row shows the official list on the issuer's own site, how we read it (a web page, an RSS feed or the site's own JSON API), how many documents the index holds, the date of the latest one and when the list was last read. If a list has never been read, or has failed for more than a day, the row says so instead of showing an old date as if nothing happened.
What we can't read yet. Under each table there's a plain line with the issuers that are in the catalogue but have no list we can read. Their circulars live in a members' area, on a page that only draws the list in the browser, or on a site that turns automated readers away. We don't get around logins, captchas or blocks. You can still pick these issuers on a vessel card, and the documents will start arriving once there's a list to read. If you know where one of them publishes an open list, tell us and we'll add it.
Seven questions are answered at the bottom of the page: how many issuers, how a list is read, how often, why some are missing, which IACS societies are covered, what happens when a list breaks and how to ask for a new one. The numbers in those answers come from the same data as the table.
On the front page. superronin.com now has a section about circulars right after the key numbers. It explains the bulletin in three points (your own issuers, port State control notices matched by IMO number, the open index) and shows the six newest documents in the index with links to the originals. Two buttons lead to the index and to the list of issuers.
The certificate register is still free while it's a pilot, the announcement has the details. Missing an issuer? Write to [email protected] with its name and the address of its circulars page.
