At least four oil tankers carrying Russian crude have come to a standstill off the western coast of India. This situation has drawn heightened scrutiny amid pressure from the U.S. and the European Union, reports Bloomberg.

According to tracking services, the vessels Achilles and Elyte are currently anchored near the Jamnagar port, failing to reach their scheduled arrival in Sikka on July 30-31.

The ships loaded their cargo at the end of June in Primorsk and Ust-Luga, locations known for loading Russian Ural crude oil. Both tankers are under sanctions imposed by the EU and the UK.

India's oil imports from Russia have been a focal point in recent weeks, particularly following new EU sanctions introduced in mid-July.

This week, the Trump administration cited these purchases as a reason for implementing high import duties on oil from India, along with threats of further sanctions.

New Delhi has urged refineries to develop and disclose plans for sourcing oil from alternative suppliers.

The vessels Achilles and Elyte, both of the Aframax type, have a carrying capacity of approximately 700,000 barrels each. The Sikka port services Reliance Industries Ltd. and Bharat Petroleum Corp. Ltd.

Reliance and BPCL have yet to respond to requests for comments.

Tracking services also report that two additional tankers, Destan and Horae, are nearby with Russian oil. Destan, under EU and UK sanctions, is expected to arrive in Sikka on July 24-25, while Horae, destined for Vadinar, is anticipated on August 1 and is not subject to EU, UK, or US sanctions.
