Offshore analysis for the offshore energy industry

Engineering insight for intelligent offshore decisions

Offshore projects operate on tight margins, where uncertainty can lead to high costs, delays or unnecessary offshore time. We provide specialist offshore analysis that supports well access, offshore development, CCS and offshore wind projects from conception to closure, across shallow and deep water.

Whether enabling drilling, intervention, CCS, redevelopment or late-life operations, we offer a comprehensive range of services on both one-off scopes and long-term analysis partnerships to provide clarity and confidence.

A smarter way to understand offshore environments

Whether guiding the first decisions of a new development, refining a campaign mid-stream or extending the life of an existing platform, analysis can deliver immediate value. Our offshore structural analysis, offshore risk analysis and wider modelling services help deliver safer, more efficient project outcomes.

Early concept and feasibility assessments: Revealing safer, smarter and more efficient options before major commitments are made

Structural, system, environmental and temperature analysis: Understanding real-world performance across varied offshore conditions

Operational limit and planning insight: Removing unnecessary conservatism, supporting regulatory compliance and cutting costly offshore time

Integrity, fatigue and lifecycle evaluation: Enabling life extension, redevelopment and safe repurposing of assets

Vessel and rig behaviour analysis: Assessing vessel motion, drift/drive-off risks, operating envelopes and marine constraints that impact well access, subsea operations and platform interactions

Offshore wind (fixed & floating): Structural, environmental and mooring analysis supporting concept evaluation, operating envelopes and campaign planning

Early insight that reduces costly rework

Early analysis reduces uncertainty and prevents costly rework during active campaigns

Well-timed studies can return value many times greater than their original cost

In one instance, a £50,000 design change avoided a £5 million retrofit

Intelligently extending asset life

Fatigue and integrity assessments have supported up to ten additional years of safe platform life

Extended operating life defers removal costs and protects ongoing production value

Intelligent engineering often reveals real structural capacity not evident in original design assumptions

Confident reuse and repurposing decisions

Structural and integrity analysis provides clarity on an asset’s potential for reuse

Engineering insight defines the conditions, limits and considerations that shape repurposing options

Early guidance reduces uncertainty and supports assured decision-making for redevelopment

Proven offshore analysis you can trust

Aquaterra Energy’s offshore analysis is trusted globally to guide safe, efficient and commercially sound offshore operations. Examples include:

INPEX Masela in Indonesia: Multi-phase riser and conductor analysis that informed rig selection, equipment specification and safe operating limits for a deepwater campaign

Multi-well programme in Egypt: Analysis across seven wells improving casing design, validating drift-off scenarios and strengthening operational planning

Urgent riser analysis in the North Sea: A 20-day turnaround that increased predicted fatigue life from three days to 132, preventing a major operational delay

Long-term analysis support in Qatar: Conductor and riser analysis for exploration, appraisal and platform wells, avoiding costly guide modifications during slot additions and recoveries

CCS feasibility work for INEOS Project Greensand: Integrity-led structural analysis exploring how existing offshore structures could be adapted for future CO2 injection and reuse
