NOAA Roles in Response to Sunken and Derelict Vessels

Doug Helton

National Oceanic and Atmospheric Administration

NOAA Ocean Service Office of Response and Restoration


Presentation Summary

  • NOAA Roles and Concerns

  • Threats from Wrecks

  • NOAA Databases

  • Response to Threats

  • Wrecks vs. abandoned vessels


Terminology

  • Salvage

    • When a vessel or cargo has residual value.

    • Removal incentive

  • Wreck Removal

    • When vessel or debris has no significant value.

    • Contract removal

  • Abandonment


NOAA interests in shipwrecks

  • National Marine Sanctuary Program

  • Office of Coast Survey

  • Office of Ocean Exploration

  • Office of Response and Restoration


Threats from wrecks

  • Oil pollution and Hazardous Cargoes

  • Smothering from vessel/debris

  • Chronic source of debris

  • Navigational obstruction

  • Trawl and navigation obstruction

  • Physical destruction of habitats

  • Illegal dump sites

  • Nutrient enrichment

  • Entrapment and Safety Hazard


Oil Pollution from Wrecks


Hurricane Katrina Salvage and Wreck Removal, 2005


1944: the M/V Empire Knight ran aground on Boon Island Ledge, ME. The vessel was carrying a mixed cargo, including mercury

1987: The Pac Baroness sank off Pt Conception, CA. The vessel was carrying 280,000 gallons of fuel and 21,000 tons of powdered copper

Hazardous Cargo:


Threats to Navigation


Habitat Threats


M/V Clipper Lasco Grounding, Fort Lauderdale, FL, 2006


Wildlife Entrapment

  • F/V Paradise Queen, Kure Atoll, NWHI

  • Entrapment of endangered monk seals


Human Health and Safety


Public Safety


F/V Van Loi, Kauai

Source of Marine Debris


  • Vessels can be a significant source of marine debris and in some situations can become debris themselves


  • Vessel debris following Hurricane Katrina


Empire, Louisiana


Samala Photos

  • As vessel deteriorate, they become a source of debris


Illegal Dump Sites

  • M/V Kimton, Fajardo, Puerto Rico

    • Vessel used for illegal dumping of waste oils and explosives

  • Abandoned Barge, Louisiana. Potential dumping site


NOAA Databases

  • Abandoned Vessels (primarily affecting corals)

  • Automated Wrecks and Obstructions Information System (Navigation hazards)

  • Resources and Undersea Threats (historic and pollution)


Abandoned Smuggling Vessel, Guam, 2008


AWOIS

  • NOAA Coast Survey

  • Automated Wrecks and Obstructions Information System


Resources and Undersea Threats (RUST)NOAA Marine Sanctuaries Program


Historic Wrecks

  • 1953: The 468-foot freighter SS Jacob Luckenbach near entrance to Golden Gate, CA. Recent response efforts removed 85,000 gallons of bunker fuel.

  • 1941: The 440-foot tanker Montebello off the coast of San Luis Obispo, CA. The Montebello was carrying more than 75,000 barrels of crude oil

Chehalis case history


USS Chehalis: Background

  • 311-foot US Navy Patapsco Class Gasoline Tanker

  • Commissioned December, 1944

  • Exploded and burned on October 7, 1949, while off-loading gasoline at Pago Pago Harbor on Tutuila Island.

  • 6 lives lost. Burned for 22 hours

  • Scuttled in 160 feet of water on October 8 near fuel terminal

  • Aviation and automotive gasoline cargo, diesel bunkers

  • 115,000 + gallons

  • 18,000 rounds of ammunition


Challenges

  • Assessing and prioritizing wrecks

  • Establishing an effective response organization

  • Developing and implementing appropriate technical solutions

  • Environmental and historic compliance

  • Funding


Hypothetical Management Decision

Risk and Uncertainty

Feasibility and costs

Health and Safety

Probability and consequences if a spill occurs

Prioritizing wrecks for remediation

Funding

Trajectory and fate

Environmental and Historical compliance


Conclusions part 1.

  • Most wrecks are probably minor threats

  • Some may contain large amounts of oil

  • We need to conduct a thorough assessment and consideration of the environmental trade-offs.

  • NOAA is working with the USCG to prioritize vessels for further investigation


Vessels Still Afloat

  • Vessels that are not maintained but are still intact/floating.

  • While floating there is an opportunity to easily and cheaply remove them before sinking creates larger problems


F/V Mwaalil Saat

  • Survey in 2003

  • Sank in 2004 during Typhoon Tingting

  • Response costs in excess of $3.5 million

  • Other floating derelicts surveyed in 2003 sank in the same storm


  • When a vessel is “lost at sea” it isn’t really lost. It continues to pose a variety of threats

  • Abandoned and derelict vessels are a problem in all coastal areas

  • Few agencies have the funds and time to address the problem
