The MV Ruby is registered in Malta, where local business records identify its owner as a company called Ruby Enterprise.

Latest accounts indicate the vessel is worth around 11m Euros.

Abdul Samin, who captained the ship in 2017, said it was built in South Korea.

A highly experienced marine surveyor, he added: “Sadly, a lack of understanding at some of the ports where the ship sought refuge, coupled with intense media scrutiny, led to confusion and delays in decision-making.

“I would like to clarify that ammonium nitrate, in its shipped form, is not inherently explosive.

“It only becomes dangerous if it’s contaminated with substances like oil or deliberately altered for explosive use.”

Mr Samin told the BBC he was impressed by how the UK authorities “handled the situation”.

“Their decisions were thoughtful, informed, and demonstrated a high level of expertise. It reassured me that the maritime industry is in good hands,” he added.

The BBC has been unable to contact Ruby Enterprise.

The ship’s management company has been approached for comment.
