Subsea Solutions

New subsea systems require a structured approach to qualification and technical assurance to help manage commercial and operational risk.

• Approval in Principle (AIP): Early-stage technical evaluation to assess novel subsea concepts against applicable class and safety criteria.

• New Technology Qualification (NTQ): A structured process to evaluate and verify the maturity, reliability and performance of new or unproven subsea technologies.

• Digital solutions and smart technology: Integration of real-time monitoring, digital twin capabilities and intelligent subsea data systems.

Applicable life-cycle phases: All project phases.

Independent technical assurance helps verify that equipment and systems comply with applicable international standards, flag requirements and regional regulations.

• Certification of systems, equipment and platforms: Verification of subsea hardware, manifolds, risers, flowlines and structural installations.

• Verification and inspection across project phases: Independent design review, manufacturing surveillance and field inspection services throughout the asset life cycle.

• Repair and remanufacturing certification: Quality and integrity assurance for repaired, remanufactured and retrofitted subsea components. 

• Regulatory body representation: Review and approval services performed on behalf of regulatory authorities, including technical engagement with the Bureau of Safety and Environmental Enforcement (BSEE).

Applicable life-cycle phases: All project phases.

Advanced analytical studies help assess structural integrity and mechanical performance in demanding subsea environments.

• Independent third-party engineering analysis: Validation of structural, hydrodynamic and mechanical design models.

• Material and metallurgical analysis: Evaluation of material selection, corrosion mechanisms, fatigue limits and metallurgical performance.

• Standards and gap analysis: Benchmarking asset designs against class requirements, American Petroleum Institute (API) specifications and International Organization for Standardization (ISO) standards. 

Applicable life-cycle phases: Concept and pre-FEED, FEED and EPCI, and life extension and decommissioning.

Targeted risk mitigation strategies help protect assets and support efficient maintenance planning while maintaining safety.

• Risk considerations for novel concepts: Early identification and mitigation of technical risks associated with new subsea designs and challenging operating environments.

• Risk studies and facilitation: Execution and independent review of hazard identification (HAZID), hazard and operability study (HAZOP), failure modes and effects analysis (FMEA), and qualitative and quantitative risk assessments.

• Risk-based inspection (RBI) schemes: Data-driven inspection programs based on asset criticality, degradation mechanisms and operating history. 

Applicable life-cycle phases: All project phases.

ABS supports offshore energy transition and environmental objectives across subsea projects.

• Environmental, social and governance strategies, implementation and verification: Technical alignment and third-party verification for environmental, social and governance programs.

• Carbon accounting and greenhouse gas measurement: Verification of greenhouse gas emissions measurement for subsea and offshore infrastructure.

• Green financing initiatives: Technical validation and independent assurance to support access to sustainable financing.

Applicable life-cycle phases: All project phases.
