THIS is the terrifying moment an oil tanker explodes instantly after ploughing into a container ship off the UK coast.

Dramatic footage shows bothwithin seconds, in the Humber Estuary, on March 10 last year.

Motin was the only person on watch duty when the horror unfolded and the Solong crashed into the Stena Immaculate at 9.47am.

Filipino Mark Angelo Pernia, 38, had been at the front of the Solong and tragically died as a result of the collision.

The part of the boat he was working on became engulfed in the blaze, and his body has never been found.

The court heard how the Stena Immaculate was carrying huge amounts of aviation fuel which leaked and subsequently ignited as a result of the crash.

A minute went by before Motin could be heard on audio saying: “Stena Immaculate, Stena Immaculate.”

In a recording from the Stena Immaculate, a loud bang was heard followed by American crew members shouting: “Holy sh**… what just hit us… a container ship… this is no drill, this is no drill, fire fire fire, we have had a collision.”

In the background, alarm bells could be heard ringing out and a ship’s foghorn was repeatedly sounded.

In another harrowing piece of video footage from the Solong, a man’s voice was heard saying: “Lord help us. Lord help us. Lord help us.”

Motin , which they did via lifeboat.

A search was launched on board for Mr Pernia but staff couldn’t gain access to parts of the ship due to the fire.

Previously, prosecutor Tom Little KC told jurors the death of Mr Pernia was “entirely avoidable”.

Motin’s defence barrister, James Leonard KC, said the defendant accepted he was the officer navigating the Solong alone on the bridge from 8am on the morning of the tragedy.

He had also spotted the Stena Immaculate on their radar system at least nine nautical miles away, and noticed it was directly in the path of the Solong.

The Solong had been on autopilot travelling at a speed of about 16 knots in the lead-up to the crash.

When the vessel was around three nautical miles away, Motin could in fact see the Stena Immaculate.

Mr Leonard told jurors: “The defendant will say that when he was approximately one nautical mile away from the Stena Immaculate’s position, he tried to take the Solong out of autopilot so as to attempt to change course to starboard manually, passing to the Stena Immaculate’s stern.

“There is no dispute that had he changed course in the way he intended, there would have been no collision.

“That attempt was not successful and the Solong did not change course at all.”

The vessel was run by 14 crew members and was carrying mainly alcoholic spirits, with some hazardous substances, including empty but unclean sodium cyanide containers, the court was told.

Meanwhile, The Stena Immaculate, with a crew of 23, was transporting more than 220,000 barrels of JetA1 high grade aviation fuel.

The trial was adjourned until Thursday after Mr Justice Baker was forced to discharge a juror.

The judge said the juror had been “distracting himself and not focusing himself on the evidence in the trial”.

Motin, from Primorsky, St Petersburg, has denied manslaughter.

The trial continues.
