The Seismic Tool

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.

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

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.

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

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

VesselPacBalArcNal # of Reports Typical Reports 18/06/2002ARC-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 29/05/2002GDN-88 It was noticed that the buckets of food waste contained teabags and plastic bags. 04/05/2002GDN-101 A plastic bag was seen discharged with the food waste. 14/03/2000PAC-12 While waiting on weather with streamers deployed, streamer one parted. 150 litres of kerosene spillage. 11/06/2000PAC-37 The observer on duty was draining a damaged streamer section for kerosene. 15 litre spillage, contained on deck. 22/02/2002PAC-7A Person was observed throwing a plastic water bottle overboard. 22/06/2002PAC-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.
