The image of 28 July

Satellite images dated 28 July show dark oil slicks near the tanker Caroline Bezengi and lighter traces north of al-Qibliyyah island. The area is a protected marine zone in Oman's Dhofar governorate. Remote-sensing specialist Wim Zwijnenburg said at least one of the hulls of the crude storage vessel appears to have been breached. The vessel is under European Union and United Kingdom sanctions; tracking data indicate it loaded Russian oil at the port of Novorossiysk.[1]

This vessel is an example of where the route cut by sanctions bends to. The restriction made carrying Russian crude through the insurance and finance network more expensive; it did not stop the carrying. The fleet that emerged moves the same cargo and ages outside the inspection network.[1]

Two explanations for a breached hull

The clearest alternative explanation for the breach is war risk. According to two maritime security sources the vessel's trouble began on 8 June off Yemen's port of Mukalla, with assessments pointing to an onboard blast. If that holds, what breached the hull was an incident, and the part sanctions play is to be sought in the question of which yard a damaged ship could reach over seven weeks.[1]

On the invoice side the arithmetic is easier. The leak sits in a protected marine area, and the burden of cleaning it falls on Oman's coastal and environmental bodies. The European Union and the United Kingdom, which imposed the sanctions, have the authority to make the vessel's trade more expensive; they have no mechanism for carrying the cost on the shore. The International Maritime Organization confirmed it is monitoring the situation.[1]

What is measurable

What will be tested here is whether responsibility can be attached to an address. If the vessel's registered insurer or operator is publicly identified and Oman and the International Maritime Organization publish a damage assessment, the cost of the shadow fleet becomes a measurable line item for the first time. As long as no such identification is made, the expense stays on the shore.[1]
