Realize Our Net Zero Future

Offshore Ammonia - Cutting Global Emissions

Together with upstream and downstream customers we are establishing world-scale offshore ammonia value chains, from the earliest phase of natural gas and CCS reservoirs identification, assessments and de-risking, through field development project execution till the actual large-scale, long-term delivery of ammonia to end users. 

The key to cutting global emissions is decarbonization of the natural gas and CCS offshore, on location. Ammonia is shuttled directly to the market without the need for downstream carbon capture and shipment for sequestration. The field development infrastructure can also be made available as CCS sink for third-parties. 

Several years of development have matured the innovative concept and feasibility studies combining proven and well recognized reservoir data interpretation, ammonia process and offshore technologies.  

Enabling Energy and Food Security

Offshore ammonia enables efficient use of stranded and associated gas in combination with CCS enabling large scale, long-term ammonia production for energy transportation and fuel consumption. 

Ammonia is crucial for large-scale mineral fertilizer production. Offshore ammonia production from natural gas with CCS can be realized on all continental shelfs and contribute to food security and self-suffiency for a growing global population in a sustainable way.

Unlocking Stranded and Flared Gas Value

Offshore ammonia & CCS field developments are unlocking the value of stranded and flared gas and accelerating the transition to a less fossil dependent future. 

FPSO-based field developments are widely accepted world-wide and a safe and efficient solution for remote locations.  They provide high degree of flexibility with respect to combined processes and re-location. Projects are scaled according to reservoir particulars, and aligned with local and regional demands. Depending on the gas reserves available, combinations of hydrogen/ammonia production, gas-to-wire and CCS can be realized. 

Together with TGS ASA and other strategic partners we offer integrated decision support in all phases of such field developments.

Project Initiation

Milestone Zero drives offshore decarbonized gas-to-hydrogen/ammonia projects and CCS by engaging with ammonia buyers, CO₂ emitters, gas and energy companies as well as regulators to initiate field development projects. We leverage expertise in reservoir data & evaluation with offshore project execution, secure partnerships, assess stranded gas fields, and advance technical and commercial models for integrated energy and CCS solutions.

Feasibility

The feasibility phase assesses technical, economic, and regulatory viability. It evaluates gas and CCS reservoirs, potential markets, development concepts, risks, and costs to determine if the project warrants further studies and investment, typically resulting in Reservoir & Facility Study Reports, Preliminary Field Development Plan (FDP), High-Level Cost and Economic Assessment, Risk Register and Recommendations for further work.

Concept Studies

The concept studies phase evaluates development options, optimizing reservoir, processing, and CCS solutions. It refines cost estimates, risk assessments, and execution strategies to identify the best concept for FEED and Final Investment Decision (FID), including Project Experience Implementation, typically resulting in Concept Selection Report, Preliminary Field Development Plan (FDP), Concept Decision Basis Document and Decision Support Package (DSP).

FEED

The FEED phase finalizes engineering, cost estimates, and execution plans. It ensures design accuracy, regulatory compliance, and risk mitigation. Bid packages are prepared for procurement, enabling informed Final Investment Decision (FID) approval, typically resulting in Final Engineering Design Package, Class 3 Cost Estimates, Execution Plan, Regulatory Approvals (Approved PDO and necessary permits) and FID Decision Support Package.

Execution

The execution phase involves engineering, drilling & subsurface work, procurement, construction, installation, and commissioning. It fabricates and integrates FPSO, subsea, and processing systems, ensuring operational readiness. Offshore installation and testing lead to first production and full-scale operations, typically resulting in Completed Subsurface, SURF and Surface Facilities, Operational Readiness Certification, Performance Tests & First Gas Production and Handover to Operations & Maintenance Teams.

Operations

Maximizes production, ensures asset integrity, optimizes costs, maintains safety, and enhances reservoir performance.

Decommissioning

Ceases production, plugs wells, removes infrastructure, restores environment, ensures compliance, and evaluates repurposing options.
