The Center for Advanced Ship Repair and Maintenance (CASRM)
is a partnership between the private ship repair yards of
Hampton Roads, Old Dominion University, CIT, and the City
of Norfolk. The goal is to make ship repair operations more
cost effective, while meeting or exceeding environmental requirements.

TBT in Shipyard Washwaters
Tributyltin (TBT) removal from shipyard washwaters and sonar
dome water has been studied for over three years using full-scale
field treatment, laboratory bench-top treatment, and both
field and laboratory pilot-scale treatment processes. This
work is ongoing and progress and final reports as well as
proceedings papers are provided. Treatment efforts have included
coagulation, clarification, filtration, GAC adsorption, UV
irradiation, membranes, and ozonation. MORE>>>
Copper and Zinc Removal
Treatment for the removal of copper and zinc from shipyard
waters has been conducted for more than seven years and is
ongoing. Copper and zinc are often found in shipyard stormwater
and drydock wash waters at levels exceeding water quality
standards. Various treatment processes have proved favorable
for the removal of copper and zinc to low concentrations and
are presented. MORE>>>
Stormwater
Research conducted by CASRM and Old Dominion University has
provided what is likely the most complete evaluation of the
relationship between stormwater runoff and water quality for
a floating drydock. This effort has led to the development
of a computer model for predicting particulate and dissolved
contaminant mobilization from a drydock surface. A report
characterizing stormwater regulatory requirements and management
practices was also developed from visits to major shipyards
along the Atlantic, Gulf, and Pacific coasts. MORE>>> |
