Specifically, DNK resulted to the possibility that the attacks were likely to have been conducted by a surface vessel operating close by that despatched underwater drones carrying 30-50 kg (65-110 lb) of high-grade explosives to detonate on impact.

For the time being, the UAE, Saudi Arabia and Norway are investigating the attacks that also affected a UAE and a Norwegian flagged vessel.

Moreover, Reuters reports that the DNK assessment came to the results below:

  • A high likelihood that the IRGC had previously supplied its allies, the Houthi militia fighting a Saudi-backed government in Yemen, with explosive-laden surface drone boats capable of homing in on GPS navigational positions for accuracy.
  • The similarity of shrapnel found on the Norwegian tanker to shrapnel from drone boats used off Yemen by Houthis, even though the craft previously used by the Houthis were surface boats rather than the underwater drones likely to have been deployed in Fujairah.
  • The fact that Iran and particularly the IRGC had recently threatened to use military force and that, against a militarily stronger foe, they were highly likely to choose “asymmetric measures with plausible deniability”.

Despite the allegations and speculation on who was behind the attack, the UAE announced that they will remain calm and try to find all the answers.

In addition, the DNK assessment noted that the attacks were conducted between six and ten nautical miles off Fujairah port.

In the meantime, DNK alleged that if Iran was behind the attack, it wanted to send a message to the US and its allies, keeping in mind that in the past it threatened to block all exports through the Strait of Hormuz.

DNK’s Managind Director, Svein Ringbakken, stated that

This is an internal and confidential report produced to inform shipowner members of the DNK about the incidents in Fujairah and the most likely explanation.
