The window of opportunity to safely remove the USS Guardian from the delicate Tubbataha Reef is closing fast, as weather conditions associated with the Amihan northeastern monsoon are expected to worsen over the next few days.

"The strong northeasterly wind and the associated big waves could affect any operation to rescue the US vessel. One thing to consider is there is another surge of the northeast monsoon this week, so expect stronger winds and heavier seas," GMA News' resident meteorologist Nathaniel "Mang Tani" Cruz said.

One method for extricating the ship being discussed by the US Navy is lifting the stuck 68-meter-long minesweeper from the reef and placing it on a larger ship.

"One-meter wave heights may not be that high considering the size of the vessel. (But) if they will do something, the window of opportunity is now as the northeast monsoon is still weak," Mang Tani explained.

Based on Weather Central data, the northeast monsoon or "Amihan" is the prevalent weather system affecting the area of Tubbataha reef, bringing cold winds from the direction of northeastern Luzon.

But Mang Tani warned that the monsoon is likely to gain in strength in two to three days, before the weekend.

Weather Central data shows that, as of Tuesday morning, wave heights in the area of Tubbataha Reef are expected to reach one meter in the next 24 hours. However, PAGASA forecaster Jori Lois told GMA News Online that the agency's data indicates that waves in the area may reach as high as two meters.

On the other hand, no rains are expected within the area, so rescuers can expect generally clear skies for at least the next 24 hours.

Weather Central's rainfall forecast for the 24 hours ending 9 a.m. Wednesday shows generally clear weather in the Tubbataha area, with possible light rainshowers west of the reef on Tuesday afternoon. — KG/HS, GMA News

They will have to pull the Guardian off the reef before they can get it on the larger vessel. it's a ship like they used to bring the USS Cole home after it was attacked in Yemen. See this pic:

for a good description on how they did this by the Military Sea Lift Command who contracted the Norwegian Heavy Seal Lift Vessel, Blue Marlin, to do the job.

But they have to get it into deeper water so that ship can submerse the deck the Guardian will rest on underneath the vessel and then release ballast to lift it up.

So, the Mustin (or some other capable vessel) will have to pull it off the reef, and then they would submerge the deck, move it under the Guardian, blow ballast and lift the deck with the Guardian on it...and then off they go.

Re: US military news thread

Half a century ago merchant ships were always getting into trouble and large tug owners, two of them Dutch, had tugs stationed all around the world, and certainly in Singapore. The Singapore tug would have been there days ago. Unfortunately for USS Guardian merchant shipping is now much safer so this service has discontinued.

Considering Subic Bay isn't that far away, I'm sure there must be a tug capable for the job close enough to have reached the location by now. I don't think that is holding up the salvage operation. I have a hunch it's more red tape than anything at this point - ie "get the ship off the reef but don't damage the reef any more". A tall order considering getting the ship off surely will grind the reef just a little more.

Re: US military news thread

The USN has contracted two "lift ships" ships based in Singapore to lift the Guardian off the reef. While this article states an attempt to de-fuel the ship was unsucessful ABC news reported this morning she has been defueled.

SASEBO NAVAL BASE, Japan — The Navy minesweeper USS Guardian — stuck on a protected reef off the coast of the Philippines for a week — will most likely stay there up to two more weeks, Navy officials said Thursday.

Rear Adm. Tom Carney, Joint Group Unit Guardian commander, said two contracted heavy-lift ships from Singapore are scheduled to arrive next Wednesday or Thursday at the site near Palawan Island to begin removing the stranded ship. The work ultimately depends on conditions at sea and efforts to stabilize the vessel and lighten its load.

During a news conference with Philippine military representatives in Palawan, Carney acknowledged that the 224-foot Guardian has moved significantly in the surf on Tubbataha Reef, a World Heritage Site; had been badly damaged with several breaches in the hull, had taken on a “significant” amount of water and now lay 20-30 yards from the edge of the reef with a 10-degree list.

“[The Guardian] will have to be lifted off onto another ship or barge to leave the area,” Carney said. “Right now, the ship could not maneuver on its own and is not operational… The ship is too badly damaged [to be towed] unfortunately.”

The comments came a day after Navy officials announced a Military Sealift Command salvage ship, the USNS Salvor, and a Malaysian tug, Vos Apollo, were also on their way to aid the vessel.

The Vos Appollo began rigging lines to defuel the vessel Wednesday but was not able to due to sea conditions, Philippine military representatives told the news conference. The Salvor is scheduled to arrive Thursday evening with divers and salvage equipment. They will make repairs and work to stabilize the ship, Carney said.

For the past two days, Navy and contracted salvage divers have been fighting rough seas to assess the water inside the Guardian and damage, plug some of the holes, secure items onboard so they don’t go over the side, and ready items to be removed to lighten the ship’s weight, Carney said. He hoped they would be able to start pumping out the 15,000 gallons of fuel Thursday.

Once the lift ships from Singapore arrive, some of the heavy items will be off-loaded while Navy architects assess how much water is inside and devise a plan to get lift equipment under the ship. The Guardian will be lifted by crane and placed on a ship or barge.

Carney said it was a “complex” salvage operation and could take as long as two weeks.

“I want to express my deepest regret for the circumstances we are in right now,” Carney said. “We are absolutely committed to removing the ship from the reef as soon as possible. That is the focus of all of our efforts.”

No one was injured when the Avenger-class mine countermeasure ship ran aground around 2:25 a.m. on Jan. 17 while transiting the Sulu Sea after a port visit in Subic Bay.

The Guardian’s crew of 79 was removed the next day as a safety precaution. The crew and officers are being interviewed and charts studied as the investigation into the incident continues, Carney said.

Navy officials have indicated faulty digital navigation charts may have led to the grounding. Carney said conditions, visibility and other navigational aids were also being looked at.

In the meantime, environmental concerns are rising the longer the ship stays on the reef.

“If the weather deteriorates, we can expect more damage,” Park administrator Angelique Songco said. “Another week of this? Unfortunately, yes… It is really sad.”
 
Glad that a concrete solution is on its way. How does a crane get into place to pick up the ship? Would the crane be part of the lift ship itself or a separate floating rig?

The news is clearly incomplete. A heavy lift ship is a ship that can be sunk until her main deck is at a considerable depth so some heavy load can be floated into position and lifted by pumping out the ballast from the ship. As they talk about two heavy lift ships I imaging the other will bring, and take away again, a floating crane. ( You might use a tug to bring the crane, Dutch built cranes and other awkward vessels were taken to Indonesia by tug when it was still a Dutch colony, but that is clearly less safe and, importantly, much slower at 2 or 3 kts rather than the 15 kts or there about of the heavy lift ship. In this case the crane will be rigged, and the Dutch cranes I mentioned were only rigged after they had arrived ). I wonder what the depth of water will be the crane works in. Or can she be allowed to stand on legs, damaging the reef only locally?
You want to take out all fuel, they are trying to do that now. You pump overboard nearly all drinking water, take off all heavy gear and put it on a barge ( Is the other heavy lift ship bringing the barge ? ). Close the breaches in the hull as well as possible, by tarpaulins on the outside or plugs on the inside and pump out as much sea water as possible. If she then doesn't yet float use you might use the crane to assist but that seem to me a rather desperate measure.
What I describe might well take two weeks, if the weather allows it. I wonder if faster results had been achieved if one or more supply vessels had been hired from an oil company that is drilling in the neighborhood. Flotation bags might have been delivered by military transport plane directly to the reef. Let's hope we'll learn which options they considered and how they made their choice.

Thanks delft! I hope this clears up this muddy situation. I think my beloved USN is holding back some info on this unfortunate incident. I really do.

After sleeping on it, I imagine that as the ship was laying initially any oil rig supply vessel might have pulled her off, if necessary using her ground tackle. If I'm wrong the supply vessel would have provided the Guardian with anchors to prevent her turning square to the waves and damaging herself and the reef in the process.
The compensation for the rescue of the ship by a supply vessel might be something like 10% of her value and USN might have balked at showing the bill to Congress especially if the vessel were to be Chinese. The total bill is now likely to be higher.
