About

Maritime Lens — Chrome Extension

What it does

Maritime Lens scans the text of any webpage you're reading and automatically underlines every maritime regulation code it recognises — MARPOL, CII, EU ETS, SOLAS, MLC, and 30+ others. Hover over any underlined term and an instant definition panel appears with the full regulation name, a plain-English summary, key numeric thresholds, and a link to the official source. No internet connection required — the entire catalogue is built into the extension.

Features

Automatic page scanning

The moment a page finishes loading, the extension walks every text node and wraps recognised regulation codes in coloured underlines. Each category has its own colour so you can tell at a glance what type of regulation you're looking at — green for environment, blue for decarbonisation, purple for EU rules, amber for safety, and so on.

Hover tooltip

Hovering any highlighted term opens a floating panel showing the regulation's category badge, the governing framework (IMO, EU, ILO), the full official title, a detailed plain-English summary, and a table of key thresholds with their numeric limits and units. The panel stays open if you move your mouse onto it, so you can read it fully and click the official source link.

Popup catalogue

Clicking the extension icon in the Chrome toolbar opens a full searchable catalogue of all 35 regulations. You can type any term — "sulphur", "ballast", "carbon", "Paris" — and matching regulations appear instantly with query highlighting. A row of category filter buttons lets you narrow to Environment, Decarbonisation, EU, Safety, Labour, PSC, or Navigation. Clicking any entry opens a full detail view with thresholds, aliases, and source links.

Match counter

The popup shows how many regulation codes were found on the current page. Useful when reviewing a charter party, PSC report, or regulatory circular to know at a glance how much terminology is present.

Enable / disable toggle

A toggle in the top-right of the popup turns highlighting on or off for the entire browser without uninstalling the extension. State is remembered across sessions.

Each regulation also recognises common aliases — so "IMO 2020", "Sulphur Cap", "0.5% sulphur", "scrubber" all trigger the SOx entry; "rest hours", "DMLC", "Maritime Labour Convention" all trigger MLC 2006, and so on.
