Southern California Oil Spill 1

As divers for Houston-based Amplify Energy Corp. on Sunday searched for the location and cause of the massive leak, public records revealed a pattern of changing ownership and compliance warnings for the company. Amplify had also been working to upgrade its aging infrastructure and had plans to initiate new drilling near the site of the leak in the final three months of this year, according to company records. It remains unclear whether the drilling had commenced or whether the work was connected to the leak.

Government officials say the spill originated from a broken pipeline off the coast of Huntington Beach that runs from the Port of Long Beach to a production and processing platform called Elly, located in the Beta Field, an accumulation of oil nine miles from the California coast. Drilling in the Beta Field, discovered by a consortium led by Shell Oil Co. in 1976, began in 1980 and oil production started in January 1981.

The exact cause of the leak remains unclear. But the devastating scope of the spill is already renewing calls for the government to take more aggressive action against the aging oil platforms that dot the Southern California coast. Environmental groups have raised the alarm for years about the condition of some of the systems and what they consider a lack of oversight.

Although California banned new offshore oil operations decades ago, platforms such as Elly continue to operate in federal waters — more than three miles from the coast.

Beta Operating Co., a subsidiary of Amplify Energy, operates Elly. The offshore facilities platform processes and routes crude oil from Ellen and Eureka, the firm’s two oil production platforms in the Beta Field, to an onshore pumping station in Long Beach via the 41-year-old, 17.3-mile San Pedro Bay Pipeline.

So the coast guard is looking for a ship with a red face whistling innocently and steaming away as fast as it can.
 
Or on the end of Tug's towing line. Ships have been known to drop an anchor when they lose power, especially in congested traffic areas. That's the only way they can stop. We often saw anchor drag scars on the Gulf of Mexico mud that went for thousands of yards when doing side scan sonar surveys for pipeline routings. Good areas to avoid if possible. We'd lay pipe 10ft deep below the mud when crossing shipping lanes to ports and 17ft for anchorage areas, but only when we could not avoid crossing those features.

 
Speaking of tugs and towlines, there are situations where the towline may drag on the sea bed due to catenary.
 
Pipe was dragged 105ft with a 13" break.

"Diver reports and footage from remote-controlled submarines showed that a 4,000-foot section of a nearly 18-mile pipeline had been displaced about 105 feet and had a 13-inch split along its length, according to the joint unified command that is overseeing the investigation."


Edit - made it more clear this was quote.
 
"Roughly 3,000 barrels (126,000 gallons) of crude oil spilled into the Pacific Ocean, killing wildlife, soiling the coastline and forcing officials to close beaches in the cities of Huntington Beach, Newport Beach and Laguna Beach in Orange County, just south of Los Angeles. As the U.S. Coast Guard Captain Rebecca Ore told reporters "[All] in all a 4,000-foot (1.2-km) section of the 17.7-mile (28.5 km) pipeline was displaced laterally, as discovered by a remotely operated vehicles."

Not a very far displacement for an anchor drag, but I doubt Godzilla had anything to do with it either.

 
I saw an interesting comment that the displacement of the pipeline could have happened long before the crack actually opened up. That may make it tricky to find the culprit.
 
Certainly possible. The degree of corrosion in the crack and how fresh the anchor scar appears could tell a bit of the story.

 

Ship Boarded Near Offshore Leak
Oct 8

U.S. Coast Guard investigators boarded the Rotterdam Express to investigate its potential involvement with the pipeline rupture, and subsequent oil leak, off of the coast of California. The cargo ship is more than 1,000 feet long and was anchored near the pipeline rupture. The ship is being investigated because of some unusual movements made the week before the leak was spotted.

On September 22nd, while anchored, the Rotterdam Express’s transponder logged movement of thousands of feet. This happened twice more on September 23rd. Hapag-Lloyd denies this, stating that the transponder data is incorrect. Hapag-Lloyd cites that the ship’s log book does not show any movement.

This is the first lead of many that the Coast Guard is investigating.

 
They cut that ship loose and said they won't be checking further with it.

Current thinking is the damage may have happened up to a year ago and corrosion only now started the leaking.

They are also saying there was a bunch of ship movement and confusion a while back in that area so they're starting to comb thru earlier AIS logs.

The investigation as to who is a worthless endeavor. The first ship investigated proved the AIS information to be in error. Every subsequent ship will be able to use the same excuse.

And now I have an idea.
 
Even if the ship anchored for an hour, is there satellite imagery that can prove the identity of a ship that was in the region up to a year ago and then prove that the ship was anchored? We have amazing spy technology when we are looking for things. It's not so great in a passive state.
 
Needle in the haystack any way you look at it, but you never know.

 
LOL, you obviously don't know what proof is. Claims aren't proof. claims don't prove it wasn't accurate. The story just says that the Coast Guard let the ship leave, nothing about the results of their investigation.
 
It's the first damn sentence:

The U.S. Coast Guard allowed the Rotterdam Express to depart from the Port of Oakland early Thursday after the cargo ship was cleared of any involvement in a massive oil spill fouling beaches in Southern California, a company spokesman said.
 
The Coast Guard letting the ship go isn't the same as them finding the AIS info was wrong. The Coast Guard might have already concluded the movement damage was older and that ship couldn't have done it and just investigated the ship because they needed to cover all leads. It was the ship OWNER said they were cleared, not the Coast Guard.

And stars get rewarded for that kind of posting...
