Footage shows Russian divers inspecting the wreckage of a sunken tanker in the Black Sea and addressing the damage caused by an oil spill from the vessel and another that ran aground.

The first video reportedly shows subaquatic workers from the Russian Ministry of Emergency Situations examining the stern of the sunken tanker, Volgoneft-212, located at a depth of 50 to 65ft (15 to 20 metres) off the coast of Russian-occupied Crimea, Ukraine, on Saturday, January 25.

The second video captures Russian emergency workers cleaning the seabed after an oil spill caused by two tankers, the Volgoneft-239 and the Volgoneft-212.

Reports indicate that up to 5,000 tonnes of oil have leaked into the Kerch Strait from both vessels, despite Russian officials denying that the Volgoneft-212 has leaked oil, although other images from Russian authorities show emergency teams working to clean the seabed.

The first video was obtained from the Ministry of Emergency Situations of the Russian Federation on January 26 along with a statement claiming: 'Emergencies Ministry rescuers inspected the stern of the sunken tanker Volgoneft-212. No fuel oil leaks were found from the hull.

'Regular monitoring of the condition of sunken tanker fragments continues. On January 25, specialists examined the stern of the Volgoneft-212 using a remotely operated underwater vehicle.

'The data displayed on the screen shows the depth and temperature readings outside.

'The inspection results show no fuel oil leaks. The soil around the vessel is fairly clean, and no oil stains were found.

'The stern of the tanker Volgoneft-212 is located 11 kilometres from the coastline. Parts of the hull are located at a depth of 20 metres. Monitoring of the stern, soil and water around is carried out regularly.'

The Ministry of Emergency Situations said regarding the second clip, also obtained on January 26: 'The elimination of the consequences of the accident in the Black Sea continues.

'Local emissions of petroleum fractions have been recorded at 17 sites over 63 kilometres long; they are being eliminated.

'Since the start of the work: more than 303 kilometres of coastline have been cleared; over 175,000 tonnes of contaminated soil were collected; 134,000 tonnes were removed to temporary storage sites.

'In the Black Sea area: 153 square kilometres were surveyed in one day, total - 5,090 square kilometres; 2,300 square metres were treated with sorbent, a total of 48,695 square metres.

'The pumping of fuel oil from the tanker Volgoneft-239 is completed.

'Divers of the Russian Emergencies Ministry continue to inspect the sunken parts of tankers using remotely operated underwater vehicles, and also collect oil products from the seabed along the coast.

'Specialists raise the collected bags of fuel oil to the surface and transport them to the shore for further disposal.'
