the world-class performance achieved during 2008.

environmental Focus Implementation of an updated company wide environment manage- ment framework was initiated during 2008, which, over time, will improve capabilities to measure, monitor and assess the environmental perform- ance of operations worldwide. PGS’ Environment Statement sets out company commitment to achieving effective environment management through implementing a process based on the principles of ISO 14001 and continuous improvement.

Updated key companywide Environ- ment Aspect Registers have been established (for primary business divisions) during 2008 and key com- pany wide Environmental Aspects have been identified for monitoring environmental performance and achieving continual improvements. These include:

  • Waste management/recycling/seg- regation.

  • Oil spill/accidental release.

  • Interaction of field operations & flora/fauna.

  • Carbon footprint/reporting.

  • Use of Best Available ‘environment’ Technology/materials/procedures.

Reduced Fuel Consumption PGS is actively investigating and assessing several alternatives for achieving improved fuel efficiency and reductions in fuel use and greenhouse gas emissions.The Company aims to lower the fuel consumption per streamer or common depth point kilometer of collected seismic data by its marine vessel fleet.The new S-class Ramform vessels, Sovereign and Sterling, are designed and con- structed with propulsion systems hav- ing improved efficiency.This results in 20–30% lower emissions than the V-class Ramform vessels.

S-Class design:

  • High-efficiency seismic vessel with high streamer capacity and bollard pull.

  • 25% longer endurance and 60% higher production capacity com- pared with the existing Ramform fleet.


  • Designed and constructed accord- ing to DNV Clean Design notation for transoceanic operating vessels.

  • The hull design includes a double skin and oil is not stored adjacent to the sea.

S-Class propulsion: The increased diameter of the noz- zle enables better propulsion.The efficiency rudder on the Ramform Sterling gives a better utilization of the propeller resulting in less fuel consumption.

Seismic Surveys and the marine environment Interest in protecting the marine environment, particularly in rela- tion to sound levels, has increased significantly in recent years. Several exploration areas have implemented specific regulations and/or guidelines relating to seismic survey activities offshore in an effort to reduce the risk to marine animals, particularly mammals, turtles and fish. PGS has experience of conducting seismic operations in many of these sensitive areas and continues to demonstrate its commitment to conducting marine operations in an environmentally responsible manner.

Generic monitoring and mitigation measures, which are now considered to be basic elements of regulatory marine mammal mitigation strategies, include:

  • Seismic survey planning.

  • Determining a suitable weather window to facilitate an efficient seismic operation.

  • Minimize the risk to marine life.

  • Marine mammal monitoring.

  • Source “soft-start” procedures.

  • Exclusion or safety zones.

The Ramform Sovereign has a purpose-built “sky lounge” to accom- modate marine mammal observers during survey operations.

Regulatory requirements for such measures vary between geographic regions and are based on a combi- nation of a precautionary approach and the results of various levels of scientific research.

It is widely recognized within the

scientific, regulatory and industry communities that there are still many uncertainties or knowledge gaps in understanding of the marine environ- ment and of any potential effects that manmade (anthropogenic) underwa- ter sound may have on marine life. Continued investments in scientific research, facilitates better understand- ing and helps governments, industries and the general public to remove some of this uncertainty.

PGS supports and actively participates in industry efforts from the Interna- tional Association of Geophysical Contractors and the International Association of Oil & Gas Producers by providing resources to support scientific research in this area.

nitrogen oxide (nox) emissions As a leading geophysical company based in Norway, PGS is committed to investing in projects to reduce its NOx emissions. An upgrading program is being implemented for existing vessels during their major yard stays in which the main machinery is being changed to low-NOx versions provid- ing the same performance:

  • Atlantic Explorer:The main engine will be rebuilt to provide a low-NOx engine resulting in a 25–30% reduc- tion in NOx emissions.

  • Ramform V-class engines: Several of the Ramform V-class vessels have had their main machinery up- graded to the best low-NOx speci- fications available in the market for that dedicated engine type.

  • Ramform S-Class:The Ramform S- class vessels are being constructed in accordance to DNV Clean Design notation which requires the NOx emissions from diesel engines to be reduced by 20% compared with the standard requirements.

PGS also participates in research and concept development activities.These are aimed at establishing renewable energy as a supplement for conven- tional fuel and to reducing the con- ventional propulsion power required on board.

HSeQ objectives 2009 The following overall HSEQ objectives have been defined for 2009:

  • The roll-out and implementation of the PGS Golden Rules of Safety throughout the organization.

  • The implementation of a HSEQ Management software tools ‘Syn- ergi’ that will improve the HSEQ reporting and management of inci- dents and data and provide better trend analysis.

  • Improvement in the HSEQ reporting and the raising of HSEQ standards in all PGS office locations.
