A large fire broke out on an oil tanker after it collided with a cargo ship in the North Sea on Monday. The BBC reports that a widescale search and rescue operation (SAR) is underway, coordinated by the British Coast Guard, as large flames and black smoke can be seen rising from the oil tanker.

According to Reuters, the tanker, sailing under the U.S. flag, is named MV Stena Immaculate and was anchored, as indicated by data from the vessel tracking tool Vesselfinder.

The British Coastguard issued the following statement:

“HM Coastguard is currently coordinating the emergency response to reports of a collision between a tanker and a cargo ship off the coast of East Yorkshire. The alert was raised at 9:48 a.m.

A Coastguard rescue helicopter from Humberside was deployed, along with lifeboats from Skegness, Bridlington, Mablethorpe [sic], and Cleethorpes, a fixed-wing aircraft from HM Coastguard, and nearby vessels equipped with firefighting capabilities. The incident remains ongoing.”

Satellite imagery from MarineTraffic shows several vessels in the North Sea area where the collision occurred.
