Lloyds and DNV withdraw Certification from all Russian Ships

These are two of the world's largest entities that certify ocean going vessels, including super yachts, for insurance purposes. What this means, is that any Russian ships certified by either of these entities may now be operating without insurance. This is a bit complicated as there are other certifiers, but these are the two used by the vast majority of ships and luxury yachts. In order to enter ports and refuel, most ships are required to show evidence of insurance. I'm not certain if this applies to all vessels owned by Russian entities or just Russian flagged ships. But this has the potential to be highly disruptive.

Update: At least one source is suggesting this is primarily being done to vessels owned by sanctioned persons, which would mostly limit it to luxury super yachts owned by Putin's cronies. More than a few of which have suddenly left their ports and turned off their satellite tracking beacons, which is against maritime law.
