tricky transfer awaits tanker inching to alaska  -  oil absorbent boom
A Russian tanker has struggled on several feet of ice in the Bering Sea to send fuel to norm.
Now the tricky part is coming: send more than a million gallons of diesel and gasoline to shore by a mile
Long hose without overflow.
The problem is that the port is frozen.
In, to prevent 370
A walking tanker from the city pier.
In order to transfer its ship No. 1, it will have to be parked at sea. 3-million-
A gallon of payload passes through the ice and reaches the head that supplies fuel to the nearby tank farm.
"I think all the precautions have been resolved," Nome Harbormaster Joy Baker said Friday . ".
"I think everything that should be done has already been done.
"For a few days, operations officials have been working on how best to lay the segmented fuel hose to the shore
Fast ice transfer.
The idea is to keep the tanker as close to the port as possible to reduce the chance of leakage.
Since the ship left Russia halfway, there has been a lot of anxiety waiting. December.
Before heading to the Dutch port of Alaska, it bought diesel in South Korea and unleaded gasoline there.
A Coast Guard icebreaker escorts the tanker through the Bering Sea to pack ice, and the two ships sometimes barely crawl as officials are looking for new technology to get the tanker out of mobile ice.
Late Thursday Coast Guard cutters Hilley and Lunda stopped at six miles offshore to wait for dawn and figured out how to get the tanker to the dock within about a mile of the port, so that its hose can reach the dock.
Nom mayor Dennis Michaels sat in her car on Friday morning and put it on the record
Break the cold and stare at the harbor entrance.
Before dawn, her eyes focused on the lights from oil tankers and icebreakers.
"It's right outside.
"You can see it," she said.
"We are very excited.
Coast Guard spokesman David Mosley said: "This is where the ship stayed on Friday night.
The Coast Guard is evaluating where to place Renda, saying: "If there is enough water around Renda, Healy can break Renda for free once the delivery is complete . ".
Healy can only be close to the coast because it is very shallow near nom.
"They are taking the time to assess where Renda will be placed for safe shore operations due to the safety of the vessel, but so that we can set them free, then let them be on the way after that, "he said.
Greg Walker, a researcher at the University of Alaska Fairbanks, said there was still a lot of work to be done before the fuel transfer occurred, and he provided information on the ice condition near the port in nomei.
The tanker needs to be safely placed on ice and moored so that it does not move during driving.
The staff will also need to complete the removal of the big stone ice in the rubble site and level the large pressure ridges to create a flat surface for the delivery hose.
Once the tanker is as close to the city pier as possible, ice must be allowed to re-freeze to keep the vessel stable.
The segment of the hose must then be bolted together and checked before the fuel starts to flow.
The personnel will go through the entire length of the hose every 30 minutes to check for leaks.
Each section has its own leak containment zone, and there will be an additional absorbing arm once it leaks.
The state requires fuel transfer to begin only during the day.
If there are enough lighting and other safety considerations, the transfer can continue in the dark, said Betty shore, industry preparation project manager at Alaska's Ministry of Environmental Protection.
Nome's North latitude hides it in the sun at this time of year, meaning after 11: 39 on Fridaym.
Sunrise, only 5 hours and 4 minutes of sunshine.
If all goes well, the transfer may be completed within 36 hours, but it may take 5 days, Schorr said.
If successful, this will mark the first time winter fuel has been delivered through the ocean to communities in western Alaska.
On November, a falling storm prevented nom from transporting fuel through a barge.
In the absence of oil tanker delivery, the supply of diesel, gasoline and domestic heating fuel Nome is expected to run out in the third quarter of April, well before the end of June or the delivery of the barge again.
The weather is very cold this winter, Mr. Michaels said.
On Friday, the temperature dropped to minus 34 degrees, breaking the record for the day of 1973.
At such temperatures, fuel is consumed very quickly, she said.
