The most important vessel on the planet has efficiently carried out the world's largest carry at sea, plucking a 24,000-tonne oil rig platform from the North Sea.

The mammoth engineering process was carried out as a part of the primary part of decommissioning probably the most necessary oilfields within the area.

Engineers took hours to place the specially-built £2.4bn Pioneering Spirit into place across the Brent Delta platform.

However it took simply seconds for the highly effective hydraulic system to carry the topside off its supporting legs, setting a world document within the course of.

The topside is now fixed onto the 382m-long ship to be transported to a scrapping yard close to Hartlepool.

In a challenge which can final 10 years, the agency plans to take away all 4 oil platforms from the Brent area within the North Sea situated 115 miles northeast of the Shetlands.

The Brent subject is among the largest fields within the North Sea and is answerable for about 10% of complete North Sea manufacturing through the previous 4 many years.

At its peak, the 4 rigs have been pumping 500,000 barrels of oil out of 154 seabed wells daily.

Decommissioning the sector can be a serious infrastructure challenge and is being intently watched by the business as a result of it's the largest North Sea area to be dismantled up to now, with a whole lot extra to comply with.

It's also being intently watched by environmental teams who've already expressed considerations about Shell (LSE: RDSB.L - news) 's planning course of.

WWF Scotland and 7 different environmental organisations have claimed the oil big's proposals include "inadequate info" and will breach worldwide guidelines.

Such guidelines state all oil rig parts have to be eliminated as soon as a platform has completed work however exceptions might be made in sure circumstances.

Shell's plan, which is being thought-about by the worldwide regulator, is to go away the concrete legs of three of the 4 decommissioned rigs on the seabed.

Lang Banks, of WWF Scotland, stated: "There are very clear worldwide guidelines setting out what Shell need to do with a purpose to show their case to go away these supplies on the seabed.

"Sadly on this case we do not consider Shell have adhered to these guidelines and they will have to return and assume once more."
