Besides providing software solutions to our clients we can also assist you with environmental services. Some of our capabilities are listed below.

Chemical Documentation

We have since 1995 assisted most of the chemical suppliers and operators with correct environmental documentation of chemicals, according to the OSPAR HOCNF (Harmonized Offshore Chemical Notification Format) framework. Our NEMS Chemicals solution is the preferred HOCNF database system in the North Atlantic.

We can assist you with advisory service and assistance with the current legislations and guidelines, prepare and quality assure your HOCNF and advise you on pre-screening of test results and ecotoxicological testing of chemicals.

Energy Management and environmental budgeting

Since 1998 we in NEMS have delivered different energy management solutions to our clients. We conduct comprehensive energy mappings, modelling and forecasting of our clients energy demand. Since 2010, we have conducted over 3 000 energy forecasts for different projects and clients. We can create forecasts for smaller unmanned platforms to larger offshore oil and gas complexes. The majority of the fields on NCS have used energy and emissions forecasts from NEMS.  All these giants we have established forecasts for.

We have designed a unified energy and environmental forecasting methodology and guidelines for the oil and gas industry.

Knowledge of energy forecasting is a key competence needed for establishing emissions forecasts and in establishing energy baselines in accordance with ISO 50001.

We also conduct environmental budgets from cradle to grave of all emissions, discharges, waste generation and chemical usage for any kind of project.

Environmental Compliance

NEMS has for decades been involved in the development of reporting guidelines and quantification methods for the oil and gas industry. We have established and update annually on behalf of the Norwegian Oil and Gas Association the environmental reporting guidelines for oil and gas operations in Norway.  We have also designed unified energy and environmental forecasting guidelines for the oil and gas industry.

We are a passionately dedicated partner when it comes to environmental compliance. At NEMS we say we are Compliant By Nature®.

Our energy and environmental experts will assist you with your environmental reporting such as annual reporting, EU ETS reporting, discharge permit application and more. Our vast experience ensure you get cost efficient and high quality compliancy work.

Over the years NEMS has worked in close collaboration with the Norwegian authorities. Norwegian Environment Agency and Norwegian Petroleum Directorate are among our clients. NEMS has also worked on multiple projects with The Norwegian Oil and Gas Association and Petoro.

Environmental Studies

NEMS has conducted several studies since the mid 1980s.

Including:

  • Review and give expert advice on clients' emission identification practices
  • Prepare complete emission inventories
  • Best Available Techniques (BAT) and Best Environmental Practices (BEP) Assessments
  • Evaluate technical and financial emission abatement opportunities
  • Prepare guidelines for environmental reporting. These guidelines outline how to calculate emissions to air, discharges to sea and waste from oil and gas facilities
  • Develop practices and methods for quantifying emissions from onshore and offshore oil and gas facilities. These methods have later been used in national inventories
  • Examine international emission quantification practices for petroleum production and compare those with other practices
  • Identify emission sources on oil and gas facilities via detailed surveys
  • Investigate emissions to air, discharges to sea and waste generation from the onshore and offshore oil and gas facilities
  • Benchmark the environmental performance of oil and gas fields
  • Quality assure reported environmental data

 

Power from Shore

Any new development on the Norwegian Continental Shelf is required to conduct a power from shore assessment (chapter 2.11 in the NPD's PDO guideline). This assessment include a technical feasibility assessment and abatement cost assessment.

NEMS has since 2002 assisted Norwegian Oil and Gas association, Norwegian Petroleum Directorate, individual operators and other stakeholders with power from shore assessments. We conduct studies for individual field developments and area evaluations.

We estimate the emission reduction potential, CAPEX and OPEX and calculate the abatement cost (cost per CO2 mitigated). We also evaluate other impact effects of power from shore.

 

Overview of previous Power From Shore projects:

Abatement cost assessment of both power from shore and offshore wind power tie-in to Neptune’s Dugong project. Conducted as subcontractor to main contractor Unitech Power Systems. 
2018/2019 Phase 2 – Power from Shore to Wisting development  OMV
An update study of study conducted in 2015/2016. Financial cost estimates, emission reduction potential and mitigation cost assessments related to power from shore to the offshore field in the Barents Sea.
2015/2016 Power from Shore to Wisting development OMV
Financial cost estimates, emission reduction potential and mitigation cost assessments related to power from shore to the offshore field in the Barents Sea.
2014 Power from Shore to Utsira Energi Norge
Financial cost estimates, emission reduction potential and mitigation cost assessments related to power from shore to the offshore fields on the Utsira high, including Johan Castberg, Ivar Aasen and Edvard Grieg, were conducted in this study.
2013/2014 Experiences with Power from Shore on Norwegian Continental Shelf (NCS) Energi Norge
Operators with experience with power from shore on NCS were interviewed regarding their experience with financial and non-financial gains and losses with power from shore. 
2012 Study update: Power from shore evaluations of Midtre Nordsjø NPD
Evaluation of power from shore to Utsira high, in the middle part of Nordsjø. The study was an update of a study done for NPD in 2011, and included CAPEX and abatement cost estimates for the individual fields Dagny (now Gina Krog), Draupne (now Ivar Aasen), Edvard Grieg, Johan Castberg and Sleipner. The study also included evaluation of integration effects, and placement of a central power hub. 
2012 Bream Field Concept Development – Power from shore study BG Group
As a sub supplier to Unitech Power Systems we conducted the abatement cost assessments, including emission reduction potential and OPEX estimates, of a power from shore concept for the Bream development
2011 Power from shore evaluations of Midtre Nordsjø NPD
Power from shore evaluation of new fields developments in the area between Sleipner and Grane, including evaluation of integration effects. The study comprised of evaluation of different technical solutions, energy and emission forecasts, emission reduction potential and abatement cost.  
2009 Electrification of Kårstø and Melkøya NPD
In the study, the emission reduction potential by replacing the power turbines on Kårst and Melkøya by electricity from the grid was evaluated. The study also included evaluation of different alternatives for heat generation. CAPEX, OPEX and abatement cost evaluations were part of the study. The project was a part of the governmental Klimakur 2020 report.
