Vessel Description

The Northstar Responder is a U.S.-flagged offshore support and emergency response vessel built in 1994 by Halter Marine, a prominent American shipbuilder historically known for constructing vessels serving the Gulf of Mexico energy sector.

Operated by Northstar GOM LLC, the vessel is configured and equipped to support offshore oil and gas operations in the Gulf of Mexico, providing emergency response, standby, and supply functions to offshore platforms and drilling units on the U.S. Outer Continental Shelf.

With a length of approximately 73 meters and significant gross tonnage of 2,415 GT, the vessel is well-suited for extended offshore operations, combining supply capability with emergency response roles including man-overboard recovery, firefighting support, and oil spill response readiness — functions typical of vessels operating under USCG certification in the GOM.
