The captain of the Solong – the container ship involved in the crash in the North Sea – is a Russian national, the vessel’s owners has said.
The rest of the crew were Russian and Filipino nationals, according to shipping company Ernst Russ.
It comes after police said a man had been arrested on suspicion of gross negligence manslaughter in connection with Monday’s collision.
Humberside Police said a 59-year-old is in custody to allow enquiries to take place, and officers are talking to those involved to find out what happened.
The force added investigators have started a criminal probe into the cause of the collision between the Stena Immaculate and Solong off the coast of East Yorkshire on Monday, and are working with the Maritime and Coastguard Agency.
One person remains missing and is presumed dead.
The tanker was operating as part of the US government’s tanker security programme, a group of commercial vessels that can be contracted to carry fuel for the military when needed.
Ship tracking software showed the Stena Immaculate was stationary as the Solong sailed towards and into it.

At around 11.20pm, the Solong started to drift southwards away from the crash site. HM Coastguard said in an update earlier on Tuesday that the ship is still alight.

Transport Secretary Heidi Alexander said the container ship is expected to stay afloat, after a minister told parliament that it could sink earlier in the day.
She said she met with the Maritime and Coastguard Agency’s chief executive Virginia McVea, and was “pleased to have been informed that early indications suggest that both vessels are now expected to stay afloat”.
Ernst Russ also denied reports the vessel was carrying sodium cyanide and said: “There are four empty containers that have previously contained the hazardous chemical.
“These containers will continue to be monitored.”
Stena Immaculate was carrying 220,000 barrels of Jet-A1 fuel in 16 tanks, at least one of which was ruptured, its operator also said.
Triple killer Kyle Clifford has been handed a whole-life sentence for murdering his ex-girlfriend, her mother and her sister.
Warning: This article contains distressing details.
The sentence imposed by Mr Justice Bennathan means he will never be released.
The former soldier, 26, admitted murdering BBC racing commentator John Hunt’s wife Carol Hunt, 61, and their daughters Louise, 25, and Hannah, 28.
He also pleaded guilty to false imprisonment of his former partner Louise, as well as possession of the crossbow used to kill her and her sister, and the 10-inch butcher’s knife he stabbed their mother to death with.

Clifford denied raping Louise, who had broken up with him 13 days before the four-hour attack in the Hunt family home on 9 July last year.
But he was found guilty by a jury last week after a trial at Cambridge Crown Court, which he refused to attend, prompting police and prosecutors to brand him a “coward”.
The judge paid tribute “to the astonishing dignity and courage” of the victims’ family, including John Hunt and his surviving daughter Amy, who hugged after the sentence.

Footage shows Clifford fleeing the Hunt family home
They, along with Hannah’s partner Alex Klein, had read emotional victim impact statements in court as Mr Hunt said hell would roll out the “red carpet” for him.
He said the evidence showed Clifford “to be a jealous man, soaked in self-pity – a man who holds women in utter contempt”.
The court heard Clifford, from Enfield, north London, began planning the murders after Louise ended their 18-month relationship in a message on 26 June.

He tricked his way inside before stabbing her mother to death in what prosecutors said was a “brutal knife attack”, then lay in wait for an hour for Louise to enter the house.
Clifford held her for more than two hours, as he restrained her with duct tape and raped her, then shot her through the chest with a crossbow moments before her sister Hannah got home and was also killed.
He fled the scene and shot himself with the weapon as armed police descended and is now paralysed from the chest down.

The judge told Clifford, who didn’t attend his sentencing hearing, he went to the Hunt family home to launch “a murderous attack” on his ex-girlfriend’s family.
“You first killed her mother Carol, who even on that day showed you nothing but kindness in the moments before you attacked her,” he said.
“You raped and killed Louise who had been as gentle as she could in ending her relationship with you, after your arrogance and anger proved too much for her to stand.
“Then you murdered Hannah Hunt, who had done nothing to harm you save supporting her little sister.”
The jury wasn’t told Clifford had searched for Andrew Tate’s podcast less than 24 hours before the murders.
Prosecutor Alison Morgan KC said “it is no coincidence” he turned to the “poster boy for misogynists – a poster boy for those who view women as possession to be controlled” the night before committing such “acts of violence against women”.
