  9. Environmental Goals FGAS - Policy is to manage its business and to provide services in such a way that it minimises the risk to the health and safety of its employees and other persons onboard, and the risk of damage or harm to the environment and wildlife.  Fugro-Geoteam AS shall not only comply with health, safety and environmental measures as required by law, but shall also act positively to prevent injury, ill health, damage and loss arising from its operations, and provide a safe and healthy working environment for its employees. IAGC – Mission is to optimize the business climate and commercial health of the geophysical industry, and to promote the conduct of business in a professional, safe and environmentally responsible manner. Clients – All clients that we work for have specific policies to reduce risk to the environment. The level of requirement and dedication varies according to each company’s corporate leadership and values.

  10. Specific Areas of Comment UK Offshore Gulf of Mexico-US Australia Tasmania 2 Australia / Antarctica

  11. Comments - Procedural UK Offshore – Regulated by the Joint Nature Conservation committee (JNCC) “The JNCC will continue to look at PON 14 (seismic) applications and assess the need for Marine Mammal Observers on a case by case basis” The JNCC sets requirements based on animal habitat and in some cases none are required (Southern North Sea) and in others such as summer north of 57 degrees two are required due to long daylight hours. Gulf of Mexico-US - MMS regulations in progress, currently require Marine Mammal observation, logging and certain start up procedures. Ongoing discussions between MMS and NOAA Fisheries to further enhance mitigation measures.

  12. Comments - Projects Australia / Antarctica – Two surveys 2001 – Duration 87 days Surveying up to the ice edge ( WD > 1000 M) FGAS used dedicated marine mammal observer onboard vessel. Surveying in WD < 1000 M used off duty personnel as marine mammal observers. 240 Whale sightings with one shutdown required 2002 – Duration 96 days Same criterea as above 34 Whale sightings with no shutdown required

  13. Comments - Projects Australia – Tasmania Full environmental prestudy submitted (see next slide) No aerial recon required (not mating season of Blue Whales) Dedicated marine mammal observers equipped with night vision binoculars. 5 Whale sightings one shutdown required

Minimise disruption to cetaceans ·Client Health, Safety andEnvironment Policy ·Environment Australia Guidelines for Minimising Acoustic Disturbance to Whales ·Environment Australia Whale and Dolphin Sighting Report ·Guidelines in place and adhered to ·‘Soft start’ procedures ·10 minute continuous whale watch every hour ·Stop work procedures if whales within 3 km ·Responsibilities for monitoring and recording ·Sighting reports completed and returned to Client and Environment Australia Minimise disturbance to benthic habitats ·Client Health, Safety andEnvironment Policy ·No anchoring of the vessel will take place during the survey ·Recording and reporting of all items lost overboard Minimise interference with commercial fishing ·P(SL)A 1967, Section 124 ·Operations carried out in a manner that does not interfere with fishing to a greater extent than is necessary Minimise interference with shipping traffic ·AMSA requirements ·P(SL)A 1967, Section 124 ·Written and radio warnings to shipping ·Operations carried out in a manner that does not interfere with navigation to a greater extent than is necessary Minimise effects of sewage discharge ·Client Health, Safety andEnvironment Policy ·P(SL)A Schedule 1995, clause 222(4) ·MARPOL 73/78 Annex IV ·Procedures for treatment and disposal of sewage are in place ·Sewage treatment system operational and includes maceration and disinfection ·Relevant discharge requirements are adhered to. Minimise occurrence of fuel and oil spills ·Client Environmental Policy ·MARPOL 73/78 Annex I ·AMSA Marine Notice 6/1995 ·P(SL)A Schedule 1995, Clause 220 ·P(SL)A Schedule 1995, Clause 285 ·Vessel Oil Spill Contingency Plan ·Vessel SOPEP (Shipboard Oil Pollution Emergency Plan) ·Procedures comply with MARPOL 73/78 requirements ·MARPOL Oil Record Book kept up to date ·Fuel spill contingency procedures are in place and operational ·Designated containment areas onboard the vessel for storage of oils, greases and streamer fluid ·Sufficient spill response equipment on board ·Appropriate actions are taken to minimise pollution ·Any spills >80 litres are reported to the Designated Authority ·Personnel responsibilities are clearly identified Minimise potential impacts of solid and hazardous wastes ·Client Health, Safety andEnvironment Policy ·MARPOL 73/78 Annex V ·Correct segregation of solid and hazardous wastes ·A vessel Waste Log Form is kept detailing quantities of wastes transported ashore ·Procedures comply with MARPOL requirements Objectives Standards Criteria

  15. Mitigation Measures • Pre-Survey studies • Environmental Impact – level as necessary • Fisheries – as warranted • Marine Mammal Observation and Recording • Dedicated or Shared • Night Vision Binocular • Soft Start of Source • Fishery Representative Onboard • Chase Vessel for Communication – local rep • Constant Communication • Environmental Incident Recording and Training

  16. Incident Reports 2000-2001 Vessel Pac Bal Arc Nal # of Reports 5 3 3 2 Typical Reports 18/06/2002 ARC-24 A small leak of oil sprung from a hydraulic pipe union by the compressor oil tanks. No record of amount of oil but believed to have been mostly contained on deck 29/05/2002 GDN-88 It was noticed that the buckets of food waste contained teabags and plastic bags. 04/05/2002 GDN-101 A plastic bag was seen discharged with the food waste. 14/03/2000 PAC-12 While waiting on weather with streamers deployed, streamer one parted. 150 litres of kerosene spillage. 11/06/2000 PAC-37 The observer on duty was draining a damaged streamer section for kerosene. 15 litre spillage, contained on deck. 22/02/2002 PAC-7 A Person was observed throwing a plastic water bottle overboard. 22/06/2002 PAC-34 During the cleaning and washing on the forecastle deck it was observed that one of the deck hand trew a piece of plastic overboard.

  17. Effects of Seismic Environmental Short Term Long Term Fisheries Short Term Long Term Economic Oil & Gas Exploration Local Economy

  18. Future • Studies of effects on Marine Mammal and Cetaceans • Species • Individual • Population • Monitoring Techniques • Improved Observation and Recording • Technical Monitoring Improvements

  19. Cetacean Monitoring System 300 250 200 150 100 50 0 Level dB re 1 microPascal @ 1 m • 10 100 1k 10k 100k 1M • Frequency

  20. Cetacean Monitoring System

  21. Conclusion • The Seismic Tool – What we as an Industry do • Environmental Goals – As Regulated and More • Areas of Operations – Oceans of the World • Mitigation Measures – Within Operational Framework • Effects of the Seismic Tool – Geophysical Oil& Gas • Future – Study, Discuss, Implement • Use technologies as available
