Vessel Support

Optimizing sampling and data collection by providing rapid mobilization and scheduling flexibility

Environmental sampling and data collection in aquatic and riverine environments often require use of small vessels, experienced and certified boat captains, and a knowledgeable crew. Small businesses that own and manage their own fleet of vessels provide clients with the advantages of rapid mobilization and scheduling flexibility, which optimizes sample collection.

Environmental Assessment Services maintains a fleet of fully equipped research vessels that can be outfitted with specialized equipment and instrumentation to meet project needs. We offer a large pool of U.S. Coast Guard-licensed captains, experienced deck-hands, divers, scientists, and technicians who have more than 100 years combined experience in a range of inland and coastal water conditions. Our team offers an outstanding record for safely performing on-water support services.

EAS uses a variety of vessels outfitted with specialized equipment and instrumentation that enable us to perform the following support services:

  • Conduct sampling and surveying in offshore areas during daylight and nighttime
  • Deploy the liquid-tip Trident probe to map contaminated groundwater upwellings and collect water and sediment samples
  • Transport staff, including divers, to job sites along and within riverine environments
  • Provide short-notice call up/emergency response
  • Transport heavy equipment, such as river pumps
  • Transport samples from the field to laboratory for preparation and shipping
  • Conduct river tours for clients.
