Hornbeck Offshore Services, Inc. was founded in 1997 and is
headquartered in Covington, Louisiana. Hornbeck Offshore
Services, Inc., through its subsidiaries, operates offshore
supply vessels (OSVs), multi-purpose support vessels, and a
shore-base to provide logistics support and specialty
services to the offshore oil and gas exploration and
production industry primarily in the United States and Gulf
of Mexico. It operates in two segments, Upstream and
Downstream. The Upstream segment owns and operates fleets of
the U.S.-flagged OSVs that support deepwater and ultra-
deepwater exploration, development, production,
construction, installation, maintenance, repair, and
enhanced oil recovery requirements of the oil and gas
industry. This segment also owns conventional OSVs, work
class ROVs, and a shore-base facility located in Port
Fourchon, Louisiana. In addition, it provides vessel
management services for other vessels owners, which include
crewing, daily operational management, and maintenance
activities. The Downstream segment owns and operates a fleet
of ocean-going tugs and tank barges that transport petroleum
products, primarily in the northeastern United States, the
Gulf of Mexico, the Great Lakes, and Puerto Rico. These tugs
and tank barges provide coastwise transportation of refined
and bunker grade petroleum products, as well as offer other
services, including the support of deepwater well testing
and other applications for refining, marketing, and trading
companies. As of December 31, 2009, Hornbeck Offshore
Services owned and operated a fleet of 47 new generation
OSVs, and 9 double-hulled barges and 10 ocean-going tugs.
