A major rescue operation was under way after a collision between an oil tanker and a cargo ship in the North Sea Monday which sparked a huge blaze and left 32 people injured.

The injured had been brought ashore for treatment "in three vessels", the Grimsby port director Martyn Boyers told AFP, adding that "ambulances were queueing on the quay".

All of the crew on board the burning oil tanker are confirmed alive, the Swedish shipowner Stena Bulk as TV images showed a huge plume of thick, black smoke and flames rising from the scene about 10 miles (16 kilometres) off the coast of northern England.

The rescue operation was being coordinated by the UK Coastguard after "reports of a collision between a tanker and cargo vessel off the coast of East Yorkshire", a Coastguard spokesperson said.

The spokesman added the Coastguard was carrying out an assessment of the likely counter pollution response required.

Images on UK television channels showed a huge plume of thick, black smoke and flames rising from the scene about 10 miles (16 kilometres) off the coast.

There were reports of "fires on both ships" that UK lifeboat services were responding to, the Royal National Lifeboat Institution (RNLI) confirmed to AFP.

There were also reports that "a number of people had abandoned the vessels", RNLI added.

The International Maritime Organization confirmed to AFP "the current focus is on the firefighting and search and rescue operation".

UK Transport Secretary Heidi Alexander said she was "concerned to hear of the collision between two vessels in the North Sea this morning and am liaising with officials and HM Coastguard as the situation develops".

She also thanked all the emergency services which rushed to the scene.

The alarm about the collision near the port city of Hull in East Yorkshire was raised at 0948 GMT.

A Coastguard helicopter, aircraft, lifeboats from four towns and other nearby vessels were part of the large rescue operation, the Coastguard added.

Swedish tanker company Stena Bulk confirmed it owned the oil tanker involved in the accident, adding that it was operated by Crowley, a US-based maritime company.

The tanker was named as the Stena Immaculate by online ship tracking service Marine Traffic, which said the vessel was anchored near its destination, Immingham, near Hull. 

It had travelled from Greece loaded with petroleum products, according to Bloomberg.

An Associated British Ports (ABP), which operates the Port of Hull and Immingham, said it was "aware" of the incident and was "assisting" the Coastguard.  

The MarineTraffic shipping tracker said the cargo ship involved was the Portuguese-flagged "Solong", owned by the German company Reederei Koepping.

Collisions rare

Vessels with firefighting capabilities have been dispatched to the scene off the northeast coast.

Collisions remain rare in the busy North Sea.

In October 2023, two cargo ships, the Verity and the Polesie, collided near Germany's Heligoland islands in the North Sea.

Three people were killed and two others are still missing, considered dead.

The Isle-of-Man-flagged Verity, which was carrying steel from the northern German  port of Bremen to Immingham, sank.

In October 2015, the Flinterstar freighter -- carrying 125 tonnes of diesel and 427 tonnes of fuel oil -- sank after colliding with the Al Oraiq tanker eight kilometres (five miles) off the Belgian coast on October 6, 2015.
