Reefed Oil and Gas Platforms
Methods of Removal
• Topple in place
– Traditional method
– Rarely used anymore
Methods of Removal
• Tow– Most common– Used for
smaller structures
Methods of Removal
• Partial removal
– Preferred method for larger structures

Biological Monitoring Methods• Roving Fish Census
• Decompression diving
• Lionfish removal
• Water quality
• Video transects
• Vertical long lines
• Photo documentation
• Biological sampling
Monitoring Events and Contracts
UTRGV (2007 – present)• Padre South protraction region
• Diving surveys, biofouling, sidescan and multibeam surveys, economic impact study
TAMU - Corpus Christi (2011 – present)• Numerous platform sites in the Mustang and
Matagorda protraction regions
• Diving surveys, tagging surveys, vertical longline, remote operated vehicle surveys, etc
• Scuba diving socio-economic impact study
TAMU - Galveston (2011 - present)• Vancouver archeological survey
• Bottom surveys and bathymetry, biological monitoring, multibeam surveys
TAMU - College Station(2013-2014)• Socio-economic survey of anglers and boaters
USGS (2013-present)• Offshore water quality survey
• Nearshore AUV, water quality, substrate survey
Reaching Out . . .
• TAMUG: 2013 – 2014 survey of anglers and boaters using TPWD license system for boats ≥ 27ft
• TAMUCC: Diver survey completed 2015
So How Important are Artificial Reefs in Texas?
• 2013-14 TAMU-College Station Survey of Licensed Boat (>26ft) Owners (7,000 boat owners)
– Reef users were white males, 57 years old, with annual income >$160,000
– 62% took a trip into GOM in last 12 months, 70% to fish on TPWD reefs
– Average trip cost = $1,652 per person
So How Important are Artificial Reefs in Texas?
• 2014-15 TAMU-CC Survey (55 dive shops and 508 divers)
– Average Texas Diver is a male 34-44 years old, 4 yrBachelor’s degree, annual income of >$70,000, lives in Corpus Christi
– Average trip cost to dive Gulf only = $1,173
So How Important are Artificial Reefs in Texas?
– Total coastal county economic impact from diving:
• Flower Gardens Banks National Marine Sanctuary only = $2.4m
• Gulf diving only = $2.5m
• Combined freshwater and saltwater diving in TX = $23m
So How Important are Artificial Reefs in Texas?
– Conclusion:
– “I don’t know much about the artificial reef program”
– “The best diving in Texas is Mexico”
