 OSLO A fierce storm in the North Sea forced oil firms to evacuate platforms and shut down production on Thursday on concerns that they could be hit by a drifting barge that had broken its anchor. 
  
 The strong winds had ripped the barge from its moorings and sent it towards BP's Valhall platform, which lies in the middle of the North Sea between Norway and Britain. 
  
 This prompted the oil and gas company to shut down output and evacuate dozens of staff on board. ConocoPhillips also stopped production and removed crew from installations in the same area. 
  
 A spokeswoman for the Rescue Coordination Centre for southern Norway told Reuters the barge eventually missed the BP platform by some two kilometres. 
  
 "The danger is over. There are no other installations between the barge and the coast of Norway," Borghild Eldoen said. 
  
 "It is now up to the owners of the barge to stop it before it reaches the coast." 
  
 A spokesman at the Rescue Coordination Centre for southern Norway earlier told Reuters that rescue boats had been trying to establish a new towing line on the barge amid difficult sea conditions, with waves of up to 15 metres in height. 
  
 BP said it was beginning the process of restarting activity on the rig, but it was too soon to say when production could resume, but that it usually took 24 hours after a complete shutdown. 
  
 ConocoPhillips declined to say when its Eldfisk and Embla fields could restart production. 
  
 The evacuations came a day after one person died and two were injured when a big wave hit a rig belonging to China Oilfield Services Ltd that had been drilling at the Troll field in the North Sea. 
  
 That rig was making its way to the Norwegian coastline on Thursday and was expected to reach land later in the day. 
  
 Close to 50 people out of 106 staff onboard, whose living quarters were damaged during the storm, had already been evacuated. 
  
 Production at the Troll gas field, operated by Statoil and Norway's largest, was not affected as the installation was a drilling rig, not a production facility, a Statoil spokesman said. 
  
 OIL TRADE 
  
 The Valhall field, operated by BP and co-owned by Hess, was producing at a rate of about 50,000 barrels per day before the shutdown. 
  
 ConocoPhillips' Embla and Eldfisk fields are also part of the Ekofisk crude oil stream, one of four North Sea crudes underpinning the global Brent oil benchmark. 
  
 The disruption could add further support to a North Sea market that has been rising due to tighter supplies of another benchmark grade, Forties, and to the wider Brent market. 
  
 North Sea traders said there was no information yet on whether Ekofisk crude cargoes had been delayed by the disruption to oil output. 
  
 "It depends how long it goes on for. It does not seem to impacting anything just yet. I don't think we'll see the impact, if there is any, until Monday," said a North Sea trading source. 
  
 The Ekofisk stream was scheduled to load about 258,000 barrels per day (bpd) in January, and the loading programme for February is expected to be issued on Monday.

 BP and ConocoPhillips oil fields evacuated as barge drifts in violent seas 
  
 Barge became unattached while being towed by a tugboat in rough weather 
  
 (CNN) Violent weather in the North Sea killed an oil worker for a Norwegian firm and prompted oil companies to evacuate workers after a barge broke loose in the storm. 
  
 Statoil, a Norwegian company, and COSL -- China Oilfield Services Limited -- issued a statement saying they had learned "with great sadness" that one person had died and two were injured when a wave broke over a drilling rig Wednesday. 
  
 The rig, called the COSL Innovator, is under contract to Statoil at the Troll field in the North Sea, west of Bergen, a city on Norway's southwestern coast. 
  
 The injured people have been taken by helicopter to shore, the statement said.

 A potential major disaster in the North Sea has been narrowly averted after a large, unmanned barge went adrift in stormy high seas and came close to colliding with offshore oil platforms. 
  
 The Eide Barge 33 missed the Valhall field by at least 1km (0.6 miles). 
  
 More than 300 oil workers were airlifted from the Norwegian sector of the North Sea after the high winds broke the barge's anchor. 
  
 Stormy weather in the area has seen waves topping 15m (50ft). 
  
 A man died when a huge wave hit another rig earlier in the Troll field off Norway. 
  
 Forced shut down 
  
 The strong winds tore the barge from its moorings and sent it towards BP's Valhall platform, located in the middle of the North Sea between Norway and the UK. 
  
 The oil and gas company was forced to shut down output and evacuate staff on board. ConocoPhillips also stopped production and evacuated crew from installations in the same area. 
  
 A spokeswoman for the Rescue Coordination Centre for southern Norway told the Reuters news agency that the danger posed by the barge was now over. 
  
 "There are no other installations between the barge and the coast of Norway," Borghild Eldoen said.

 "It is now up to the owners of the barge to stop it before it reaches the coast." 
  
 At one point fears about a collision increased when the barge - 110m in length and 30m wide - changed course and headed straight for Valhall, BP Norway spokesman Jan Erik Geirmo told the AFP news agency. 
  
 But in the event it floated away from the evacuated platforms. 
  
 Mr Geirmo said that a tug had been deployed to immobilise it - an operation which will be dangerous in such stormy conditions. He said the situation was now returning to normal and employees will progressively return to the platforms. 
  
 Norwegian media said the barge ran adrift on Wednesday evening some 25km (15 miles) from Valhall. |||||
Output:
BP says 150 people have been evacuated from its offshore oil platforms in the North Sea due to an unmanned barge drifting in rough seas toward the Valhall oil field. A company spokesman says the evacuees were taken to other oil fields as a precaution, and that 85 people remained on platforms in the Valhall field Thursday morning. He says a tugboat is trying to gain control of the barge, which broke from its anchor and started drifting amid strong winds and high waves late Wednesday. CNN reports that the 360-foot barge has begun drifting north, forcing ConocoPhillips to evacuate 145 workers from an oil field. Earlier, Norway's Statoil said one worker was killed and two were injured when a big wave slammed into a drilling rig Wednesday in the Troll field, also in the North Sea. A spokesman for Norway's coast guard tells the BBC that the wave that hit the workers' accommodation block on the rig must have been around 60 feet high. Two other workers were injured. The rig is now making its way back to Norway with more than 50 workers aboard. Another 50 were evacuated after the accident, and a Petroleum Safety Authority Norway spokeswoman tells Reuters that they had to be lifted off the platform because winds were too strong for a helicopter to land.
