Subject: [CPEO-MEF] BIW's floating drydock from China - exotics aboard?
 
[Towards the middle of the posting the author poses a question for CPEO MEF 
readers. --Aimee]

Friends -
Bath Iron Works,  builder of Aegis missile cruisers and other naval
vessels, has just had a very large floating drydock towed from its assembly
place on the Chinese coast to the BIW/General Dynamics facility on the
Maine coast.  Inquiring scientists want the  hull and ballast water spaces
examined for exotic marine pest species, such as the asian shore crab, or
Chinese mole crab.  How do we get these fine folks to agree to do so?

The voyage of the drydock, thanks to a typhoon and other unforeseeable
events , took triple the planned length of time. The drydock left China on
August 27, 2000, and  arrived  February 17, 2001  at the Bath Iron Work's
facility in Bath Maine on the Kennebec River.  The drydock & the towing
tugboat had stops along the way in Pusan, Korea, and San Juan, Puerto Rico.

Profile of the arrival of the drydock in Maine can be viewed at a local
Maine news service: http://rockland.k2Bh.com/Community/Story.cfm?StoryID=5267

A number of scientists and others, including at Maine DMR are interested in
determining whether the floating drydock transported exotic marine
organisms to Maine as well.  This includes both its ballast water ( a very
substantial amount),  the sediment and organisms that settled out of the
ballast water and congealed on the sides and bottom of the drydock's
ballast tanks, and the fouling organisms that fastened onto the submerged
hull portions of the drydock during the journey.

See discussion of the role of drydocks in aquatic suisance species
transmission at the International Joint Commission's  " White Paper On
Policies for the Prevention of The Invasion of the Great Lakes by Exotic 
Organisms"
http://www.ijc.org/milwaukee/wrkshps/epballast.html

Exotic species such as the asian shore crab can have marked impacts on
coastal ecosystems that do not have them, yet have the environment that
allows them to colonize.

Given the extended length of the BIW floating drydock's journey, thanks to
the unexpected typhoon, and other delays, there was a substantial amount 
of time for bottom fouling organisms to grow on the hull.   This is a very
common phenomenon.  One of the concerns, as we have very few ships from 
China making a call on a Maine port, is that Chinese crustaceans, such as 
the Asian shore crab and the Chinese mole crab,  could survive the voyage 
amid the barnacles and other fouling organisms on the drydock hull in 
sufficient numbers to colonize the midcoast and waters south in the Maine 
Coastal Current plume.

Researchers and bio-invasion specialists suggest that the outer  hull and
the interior ballast spaces  be examined, and samples collected, using
either divers or an ROV (remotely operated vehicle).    If Asian shore
crabs or other nuisance species are detected,  then standard  aquatic
nuisance species removal techniques would be employed, similar to those
used to clear floating drydocks and municipal water intake pipes in the
Great Lakes area of zebra mussels and other pest organisms, without
spreading them into the water column.

All in all, not terribly expensive and a good precautionary exercise that
will also inform the scientific community on an issue of great interest to
them. With environmental security being part of the greater defense
mission,  this is one worth doing.

My question to CPEO-military is How does one go about getting such a
defense contactor as General Dynamics/Bath Ironworks to go along with the
bio-researchers?

Bath Iron Works Bath, Maine 04530
Tel:  (207) 442-1149 E-mail: susan.pierter@gdbiw.com
Sue is agreeable to having this looked into, and has passed the inquiry to
her company's science people.

* John Sowles,  Maine DMR marine science  officer , West Boothbay 
Harbor.  john.sowles@state.me.us   Tel: (207)633-9500

Months ago,  Sowles requested that BIW be sure that the 
drydock  followingaccepted International Maritime Organization protocols 
and  dump itsChinese ballast water in mid ocean before taking on a load of 
"clean"
midocean water ballast,  prior to arriving in Maine waters. He doesn't know
yet whether they did so, but in response to inquiries from NGO and 
academicpersons, is considering  assembling the needed divers and others 
to adequately sample the fauna and flora attached to the submerged parts 
of the floating drydock's hull surfaces and ballast spaces.

*James Carlton,  past head of the International Maritime Organization's
aquatic nuisance species study committee and editor of "Biological
Invasions" a scientific journal devoted to this topic.  Carlton is
participating in a research into the phenomenon of floating drydocks as
exotic species transport vectors.  He will be attending an international
meeting on just that issue next week; he considers the BIW floating 
drydock to be a significant  potential transmission vector, and would be 
glad to help arrange for the examination  and sample gathering.
