Some 64 specialists from the Army's Edgewood Chemical Biological Center are expected to depart for the Mediterranean in about two weeks aboard the ship MV Cape Ray to destroy chemical weapons from Syria.
The nearly 650-foot-long ship, now in Portsmouth, will travel to a yet-to-be specified location in the Mediterranean and will take on about 700 metric tons of both mustard gas and "DF compound," a component of the nerve agent sarin gas, and will then use two new, and recently installed "field deployable hydrolysis systems" to neutralize the chemicals.
Onboard the Cape Ray will be 35 mariners, about 64 chemical specialists from Edgewood, Md., a security team, and a contingent from U.S. European Command. It's expected the operational portion of the mission will take about 90 days.
Outside the ship, Jan. 2, Frank Kendall, under secretary of Defense for acquisition, technology and logistics, said preparations began before the United States even knew it was committed to the mission -- or that the mission would ever materialize.
"There was a recognition that something was going to happen in Syria, in all likelihood that would require us to do something with those chemical materials that were known to be there," he said.
In December 2012, a request was made to determine what could be done if the U.S. was asked to participate in destruction of chemical weapons from Syria.
By the end of January 2013, a team with the Joint Project Manager for Elimination and the Army's Edgewood Chemical Biological Center in Edgewood, Md., had evaluated existing technology and configurations for neutralization of chemical weapons and made the recommendation to use the hydrolysis process. Construction of a deployable system began in February, and the first prototype was available in June. A second was available in September.
"We could have waited to see what happened and then reacted to that, or we could have moved out ahead of time and then prepared for what might happen or was likely to happen," Kendall said. "Fortunately ... we took the latter course."
Onboard the ship, an environmentally sealed tent contains two Field Deployable Hydrolysis System, or FDHS, units, which will operate 24 hours a day in parallel to complete the chemical warfare agent neutralization mission.
Each unit costs about $5 million and contains built-in redundancy and a titanium-lined reactor for mixing the chemical warfare agents with the chemicals that will neutralize them.
About 130 gallons of mustard gas can be neutralized at a time, over the course of about two hours, for instance, said Adam Baker, with the Edgewood Chemical Biological Center.
The FDHS systems can, depending on the material, process between 5 to 25 metric tons of material a day. With two systems, that means as much as 50 metric tons a day of chemical warfare agents can be destroyed. The mission requires disposal of 700 metric tons of material. But the plan is not to start out on the first day at full speed.
"There is a ramp-up period," Baker said. "It's going to be a slow start. We're going to go very deliberately and safely."
Rob Malone, with the Joint Project Manager for Elimination at Edgewood, said the two chemical warfare agents will be neutralized with reagents such as bleach, water or sodium hydroxide.
"They are doing a chemical hydrolysis process. It brings the chemical agent together with a reagent, another chemical," Malone said. "It creates a chemical reaction that basically destroys the chemical agent in and of itself."
The result of that neutralization process will create about 1.5 million gallons of a toxic "effluent" that must be disposed of, but cannot be used as a chemical weapon. Additionally, Malone said, the effluent is similar to other toxic hazardous compounds that industrial processes generate. There is a commercial market worldwide for disposing of such waste.
The effluent will be acidic and will be PH-adjusted to bring it up to "above neutral," as part of the process. The end result will be a liquid that is caustic, similar to commercially-available "Drano," said Baker.
The operational plan includes a cycle of six days of disposal plus one day for maintenance of the equipment. On board will be about 220 6,600-gallon containers that will hold the reagents used in the disposal process, and will also be used afterward to hold the effluent.
"Everything will be kind of contained on the ship throughout the entire process," Malone said.
YEARS OF EXPERIENCE
The U.S. has never disposed of chemical weapons aboard a ship before. But it has spent years disposing of its own chemical weapons on land, using the same process that the FDHS uses. The chemical process is not new, and neither is the technology. The format, field deployable, is new, however. And the platform, aboard a ship, is also new. And these additions to the process have created challenges for the team.
"This has not been done on this platform, not been done at sea," said Baker. "But it is taking the established operations we've done at several land sites domestically and internationally and is applying them here."
In the U.S., the military has been destroying its own chemical weapons for years at places like Aberdeen Proving Ground, Md., and the recently-closed Pine Bluff Arsenal, Ala. Lessons from those facilities and others were used to develop the process that will be used aboard the Cape Ray to destroy Syrian chemical weapons.
The process for disposing of mustard gas was used at Aberdeen Proving Ground. The process for disposing of DF compound was taken from Pine Bluff Arsenal, Baker said. The processes and technologies from those locations were scaled down to make them transportable.
"So there is no mystery about the process," Kendall said. "It is a slightly different scale that we are doing it at here. We had fixed installations that had hydrolysis units that could do this job. But what we did not have was a 'transportable, field deployable' [system], the words we're using for these systems, that could be moved somewhere else."
Malone, who has 20 years of experience destroying chemical weapons for the United States, said doing aboard a ship what he has done on land for two decades required some additional thought and effort.
"We had to figure out on the Cape Ray how to operate in three dimensions," he said.
The FHDS systems are inside tents inside the ship, for example. But the chemical weapons may be loaded on the ship on the deck above, and additional materials will be a deck below the FDHS equipment. On land, everything is spread out and on one level, he said.
"That's been the significant challenge and things we've had to overcome to get the Cape Ray ready for deployment," he said.
Additionally, vibration studies were done to learn how lab equipment would operate on board a ship, he said. And the equipment had to be modified to anchor it into the ship using chains.
In the U.S. chemical weapons demilitarization program, many times it is munitions that contain chemical weapons that are being demilitarized, such as rockets and projectiles that include a casing and explosive as well as the chemical component.
"Really, that's that part that really limits throughput a lot of time, the de-mating of the explosive from the chemical agent and the body," Malone said.
But aboard the Cape Ray, the mission will be different. It is not munitions that are being demilitarized, but liquid chemical agents.
"This can be done fairly quickly because all of the material we are receiving are going to be in a bulk configuration," Malone said. "It's in large vessels, easily accessible, and for us it gives us a very high throughput."
The chemical weapons also lend themselves to faster neutralization, he said.
ONBOARD THE CAPE RAY
Rick Jordan, captain of the Cape Ray, a mariner for 40 years now, and an employee of contractor Keystone Shipping Company, said for this mission his crew was expanded from 29 to 35. The additional six will support mainly what he calls "hotel services" aboard the ship.
"We've got some really good folks on here that know how to train, and we've been training them," he said. "They've got all kinds of shipboard damage control, damage control training and that sort of thing."
He also said there is plenty of support for spill response as well as for fire suppression.
"The whole key here is teamwork," he said. "There has been an unbelievable amount of teamwork in this whole process, from the Maritime Administration, Military Sealift Command, to the Keystone Shipping Company. I'm humbled by what is going on here. We've had about three or four days of hard training together where we've been making mariners out of them, and they've been making chemical destruction folks out of us. And we're going to continue to train. The whole trip will be a combination of production, training and being ready for the worst-case scenario."
Jordan said he has not yet received sailing orders, but estimated the time to sail to the center of the Mediterranean Sea at about 10 days. The mission will last 90 days.
That 90-day mission has about 45 days built in for "down days" due to bad weather. So the mission could be shorter.
"Weather is the single most important factor as a mariner that I have got to consider," Jordan said. "The good news for the Cape Ray is we have lots of things to mitigate weather on board."
He said the ship is equipped with stabilizers to dampen any roll. He also said that because the ship really has no destination, but is rather meant to serve as a platform, he can navigate around weather if need be.
Sea trials for the mission have already begun, and the Cape Ray will do more sea trials before it departs on its mission in about two weeks. It's expected the mission will include the neutralization of about 700 metric tons of chemical weapon agents. Those agents will be transferred to the Cape Ray from both Danish and Norwegian ships in a process expected to take about one or two days.
"Exactly where and how that process will take place has not been finalized yet," Kendall said.
Additionally, U.S. Navy assets will provide security for the ship while it conducts operations, Kendall said.http://www.army.mil/article/117790/Army_team_to_destroy_Syrian_chemical_weapons_afloat/
