ConocoPhillips Global NVE Greenland LTD. - 1 - Final Supplemental Filing 20 June 2012

1 Introduction

This document is a Supplemental Filing related to the Final Environmental Impact Assessment (EIA) of a 2D-seimic survey in Block 2 (Qamut) that was submitted to the Bureau of Minerals and Petroleum (BMP) on 14 June 2012 by ConocoPhillips Global NVE Greenland Ltd., DONG E&P Grønland A/S and Nunaoil A/S (referred to collectively as “ConocoPhillips”). This seismic survey would take place from early August to mid-September 2012, with the option of extending to 1 October 2012 if ice conditions, weather conditions, sea state or other factors delay the program.

It was noted in Section 3.1 of the Final EIA that three vessels had been chartered by ConocoPhillips for the seismic survey in Qamut Block, including: one ice-class seismic survey ship; one ice-class chase vessel; and one support and re-supply vessel. The CGGVeritas M/V Princess was identified as the ship that would be performing the 2D-seismic survey (including collection of marine gravity and magnetic data). The chase ship and support/re-supply ship would be the M/V Thor Supplier and the M/V Thor Beamer, respectively. This fleet was part of the basis for environmental assessment in the Preliminary EIA. In early June 2012, it was necessary for ConocoPhillips to change these ships. They have been replaced by equivalent vessels, including the Artemis Angler as the seismic ship, F/F Meredian as the chase ship, and MV Arctic Star as the support/re-supply ship (which may act as a second chase ship). ConocoPhillips mentioned that the airgun array and single streamer that will be deployed by the Artemis Angler would be identical to the airgun array and single streamer that would have been deployed by the Princess. It was also noted that CGGVeritas would continue to be the seismic contractor for the survey.

ConocoPhillips decided that the Final EIA would not be altered to reflect this change in the fleet of ships, or “Change of Fleet”, since it was an operations planning adjustment that is not uncommon during seismic surveys when release of a ship, or ships, from a previous charter has been delayed, or when any or all of the proposed ships are not available for other reasons. It was indicated, at the time, that the Change of Fleet was not regarded as material or significant from an environmental assessment perspective, and that it would be addressed by ConocoPhillips during the “Application Package” process for the 2012 program, or in a Supplemental Filing to BMP. Finally, in light of this situation, it was explained that mention of the Princess, Thor Supplier or Thor Beamer in the rest of Section 3, or in other sections of the Final EIA, would be left as is.

The Change of Fleet is discussed in this report. The replacement fleet is compared to the original fleet from an environmental assessment point of view, based on impact significance ratings for specific potential effects after mitigation measures have been applied at block or licence level. ConocoPhillips does not believe it is necessary to extend the comparison to cumulative effects of underwater sound at regional scale, since the airgun array, in particular, will not be changed from the airgun array that was modelled and assessed in the Final EIA. It will be configured the same way, and operated that way along the same number of sail lines, during the survey. The total number of line-kilometres will be identical.


2 Vessel Details and Operations

The vessels comprising the replacement fleet are described in Appendix A (seismic survey ship) and Appendix B (chase ships). A small amount of additional information is provided below.

The airgun array deployed by the Artemis Angler will be identical to the array that would have been deployed by the Princess, as noted above. The other active sound sources on the Artemis Angler will be equivalent to those on the Princess, including: a ship’s own echosounder for safety of navigation purposes (Furuno FE 680), and a dedicated single-beam system for accurate depth measurement during the seismic survey (Simrad EA 500).

Collection of marine gravity and magnetic data by the seismic survey ship will not be altered by the Change of Fleet. This information is obtained with passive measurement systems that do not emit sound or energy.

The passive acoustic monitoring (PAM) system on the Artemis Angler will be the same as the system that would have been used on the Princess. The four hydrophones will be deployed aft of the ship in a similar manner, and the system will be operated the same way.

The classification of Artemis Angler, according to CGGVeritas, is DNV +1A1 ICE C (hull constructed to ICE 1B specification; rudder, propeller and blisters are ICE C), compared to DNV 1A1 ICE 1A for MV Princess. The Angler has a lower ice class, but ConocoPhillips believes this level of ice strengthening will be sufficient for “open water” or “ice free” operations in Qamut Block during the survey period. The ice class of the two chase ships is equal or higher. The Ice Management Plan for the survey is not altered by the Change of Fleet. It will continue to be focused on ice avoidance.

The Artemis Angler is equipped with a helipad, which likely has implications for medical evacuations, and transfer of personnel for other reasons (death or serious illness of family members, for example). The Princess did not have a helipad. The Emergency Response Plan for the seismic survey will be modified accordingly.


3 Change of Fleet from an Environmental Perspective

3.1 Effects of Airborne Emissions from Project Vessels

Table 3.1-1 presents the total fuel consumption for the new fleet of ships compared to fleet of ships assessed in the Final EIA Report submitted to BMP on 14 June 2012. This table, in part, reflects Table 6.1-1 on page 33 in the Final EIA Report. All assumptions for calculating fuel consumption related to the original fleet and the replacement fleet are the same.

Table 3.1-3 presents the total estimated greenhouse gas emissions of the replacement fleet compared to the fleet assessed in the Final EIA Report submitted to BMP on 14 June 2012. This table, in part, reflects Table 6.1-3 on page 34 in the Final EIA Report.

CO2e refers to “CO2 equivalent”, based on 100-yr Global Warming Potentials (GWPs) taken from Environment Canada (2011). The estimates in Tables 3.1-1 to 3.1-3 for the ships comprising the new fleet are roughly 65% of the estimates for the three vessels assessed in the Final EIA Report. The impact significance rating for air quality is not altered from “negligible” by the Change of Fleet. All other considerations in the Final EIA apply.

3.2 Effects of Discharges from Project Vessels

In Section 6.2 of the Final EIA, the estimated discharge of grey water and black water was 15.2 m3 and 1.9 m3 per day, respectively. These estimates were based on a probable (maximum) complement of up to 60 personnel (all vessels), and EPA (2008) average daily per person production rates for these discharges. The total complement on the three replacement vessels will be similar or slightly higher. The black water and grey water discharges will not be appreciably different. No other effects on discharges, involving liquid or solid waste are expected during the survey from changing the ships. The impact significance ratings of “negligible” for water quality, marine fish, seabirds and marine mammals are not altered by the Change of Fleet. The Waste Management Plan will not be affected. All other considerations mentioned in the Final EIA apply.

3.3 Effects of Underwater Sound on the Marine Environment

As mentioned earlier, the airgun array on the Artemis Angler will be identical to the array that was modelled and assessed during the Final EIA. Consequently, no changes are expected for Effects of Underwater Sound on the Marine Environment, including marine mammals and fish, related to the Change of Fleet. This involves the seismic sound source, other active sources, or sound produced by propellers, shafts or engines. The safety zone is not altered from a radius of 800 m centered on the airgun array. The Marine Mammal and Seabird Observation (MMSO) Plan will not be affected. All other considerations mentioned in the Final EIA apply.


3.4 Effects of Vessel Traffic

There are no expected changes for Effects of Vessel Traffic, including ship strikes with marine mammals, since the number of ships, transit speed to and from Qamut Block and speed maintained during the survey are not changed from the original fleet. ConocoPhillips believes that all three replacement vessels will be operated in the same competent and professional manner, based on “best practice at sea” and compliance with applicable CGGVeritas standards.

3.5 Effects of Vessel Lighting

No change expected for Effects of Vessel Lighting. The survey period is not altered by the Change of Fleet, and consequently, the estimates for length of daylight/twilight in Qamut Block (since lighting will be required during periods of darkness or deep twilight only) in the Final EIA are not affected.

3.6 Effects of Introduced Species from Ballast Water Exchange

No change is expected for for Effects of Introduced Species from Ballast Water Exchange involving the Change of Fleet. The Ballast Water Management Plan will need to be modified, however, since it is ship-specific for Artemis Angler and the two chase vessels.

3.7 Effects of Unplanned Events and Accidental Spills

In Section 6.7 of the Final EIA, the scenario assessed for a major unplanned event was a 300 m3 accidental spill of marine diesel fuel (MDF) due to collision of MV Princess with another ship, or with an iceberg, that led to rupture of multiple tanks. This number was one-third to one-half of total tank capacity (692 m3, or “full fuel”) for the Princess, which was regarded as a realistic operational situation for assessment purposes. The total tank capacity for Artemis Angler is 800 m3. The corresponding value for a major accidental spill would be 350 m3. ConocoPhillips does not believe an increase of 50 m3 is significant for this scenario. The impact significant ratings of “low” for seabirds and marine mammals, and “negligible” for sediment quality, water quality, marine fish and subsistence hunting/fishing, are not altered by the Change of Fleet. No differences are expected for minor unplanned events. Procedures onboard the Artemis Angler will conform to applicable CGGVeritas standards. All other considerations mentioned in the Final EIA apply.
