R/V Tiglax

Research vessel Tiglax in AK

Project Details

The R/V Tiglax (TEKH-lah—Unangam Tunuu or Aleut for eagle) is a U.S. Fish and Wildlife Service vessel based in Alaska. Its crew works for the Refuge as its research and transportation support vessel.

The vessel received an overhaul at Snow & Company, and the captain sought to upgrade its engine room. After much planning and discussion, the decision was made to go with sound-attenuated BOLLARD marine generators running in parallel with a Main Switchboard (MSB).

The MSB facilitates transferring load between machines, and synchronizing and circuit breaker control are automatic and reliable.

The Tiglax travels 15,000 to 20,000 nautical miles a season, so reliability is essential. This BOLLARD integrated system will allow them to run cooler, more efficiently, and save fuel during their season.
