NEMS has delivered energy management, modelling and forecasting services since 1998. Our experts map energy demand and prepare forecasts for projects ranging from smaller unmanned installations to large and complex offshore developments.

Since 2010, NEMS has completed more than 3,000 energy forecasts for projects and operators. Our forecasting methodologies support energy planning, emissions forecasting and the establishment of energy baselines.

We also prepare environmental budgets covering the complete project lifecycle, including:

• emissions to air
• discharges to sea
• energy and fuel consumption
• waste generation
• chemical use and discharge
• production and activity assumptions

Forecasts and environmental budgets can be prepared for individual assets, developments, portfolios or wider area studies.

NEMS has conducted environmental studies and developed environmental methodologies for the oil and gas industry since the 1980s.

Our services include:

• identification and mapping of emission sources
• Scope 1, Scope 2 and Scope 3 emission inventories
• Best Available Techniques and Best Environmental Practices assessments
• technical and financial evaluation of emission-reduction opportunities
• development and review of environmental reporting methodologies
• quantification of emissions to air, discharges to sea and waste
• comparison of international emission-calculation practices
• environmental performance benchmarking
• quality assurance of environmental data and reported figures
• facility surveys covering offshore and onshore operations

Studies can be delivered independently or supported by data, calculations and reporting from the NEMS Environmental Management Suite.

NEMS has decades of experience developing environmental reporting guidelines, quantification methods and reporting processes for the oil and gas industry.

Our environmental specialists support:

• annual environmental reporting
• emissions and energy reporting
• EU ETS reporting and documentation
• discharge permit applications
• environmental authority reporting
• emissions inventories and calculation methodologies
• quality assurance and verification support
• development of company-specific reporting guidelines

We help organisations interpret reporting requirements, document calculation methods and establish efficient, traceable processes from environmental data to final submission.

NEMS has worked closely with operators, industry organisations and Norwegian authorities on environmental reporting and methodology development.

NEMS has supported offshore chemical suppliers and operators with environmental chemical documentation since 1995.

Our specialists can assist with:

• preparation and quality assurance of HOCNF documentation
• interpretation of OSPAR requirements and relevant guidelines
• review of chemical composition and environmental documentation
• pre-screening of ecotoxicological test results
• advice on biodegradation, bioaccumulation and toxicity testing
• environmental classification and substitution assessments
• supplier and operator support throughout the chemical approval process

These services complement NEMS Chemicals®, our digital solution for structured offshore chemical documentation and management.

NEMS has supported operators, authorities and industry organisations with power-from-shore assessments since 2002.

Our studies can include:

• technical feasibility assessments
• energy-demand modelling
• estimated emission-reduction potential
• CAPEX and OPEX estimates
• calculation of abatement cost per tonne of CO₂ reduced
• evaluation of operational and environmental impacts
• assessments for individual fields, developments and wider areas

NEMS can also evaluate alternative emission-reduction measures and compare their technical, environmental and economic performance.

NEMS advisory services can be delivered independently or combined with the NEMS Environmental Management Suite.

By combining specialist environmental expertise with structured data management, calculations, integrations and reporting, organisations can establish more efficient and traceable environmental processes.

Our experts can support the development of methodologies, forecasts, reporting structures and quality-assurance processes that are subsequently implemented in NEMS Accounter®, NEMS Panorama® or NEMS Chemicals®.
