Studies, EPCI Support & Decommissioning — Delivered.
VORYX combines senior offshore engineering expertise with practical project execution experience to deliver technically robust, commercially practical, and execution-focused solutions across the offshore energy sector — reducing risk, optimising CAPEX/OPEX, and protecting schedule from concept through to offshore completion.
// About VORYX
VORYX combines senior offshore engineering expertise with practical project execution experience to deliver technically robust, commercially practical, and execution-focused solutions across the offshore energy sector.
We are an independent offshore engineering and project delivery consultancy founded by senior practitioners with hands-on careers inside major operators, EPC contractors, offshore installation companies and fabrication yards. Our work bridges engineering studies and real offshore execution — not theoretical consultancy.
Across our team, we bring more than 50 years of combined offshore and project execution experience across the full asset lifecycle: concept and FEED, detailed design, fabrication and load-out supervision, offshore installation, commissioning, and late-life abandonment and decommissioning. Our delivery footprint spans Asia-Pacific, the Middle East, Australia, Africa and Europe.
Pipeline Technical Authorities, EPC Project Managers and Fabrication Site Reps — not junior engineers learning on your project.
Careers built inside major operators, Tier-1 EPCs, installation contractors and offshore yards — we speak every interface fluently.
Every deliverable is screened against fabricability, installability and offshore execution — engineering that survives contact with the sea.
Senior-led, low-overhead delivery — faster decisions, fewer hand-offs, and clear commercial accountability versus large engineering houses.
// What We Do
// Why VORYX
Studies are screened against real fabrication, transportation and installation constraints — engineering that builds, not engineering that files.
Our team has supervised offshore campaigns, yard fabrication and load-outs first-hand — not just from an office.
Careers built inside major operators, Tier-1 EPCs, installation contractors and offshore fabrication yards — fluent on every side of the contract.
Senior-led delivery, minimal overhead and short decision chains — faster turnarounds and clear commercial accountability.
One partner from FEED through ITT, fabrication and offshore execution — no expensive hand-offs between study house and execution team.
Platform, subsea and pipeline abandonment, P&A concepts, comparative assessments and OSPAR / NOPSEMA / BSEE-aligned strategy.
CAPEX / OPEX framing, value engineering and ITT preparation built into the engineering — not bolted on afterwards.
Nonlinear FEA, lateral buckling & pipeline walking, SAFEBUCK methodology, strain-based design and ECA aligned with DNV / API / ISO / AS2885.

A representative selection of work delivered by VORYX team members across studies, EPCI / EPRD execution support and decommissioning. Operator and project names are anonymised here for confidentiality and disclosed on request.
FEED-phase decommissioning of 27 platforms, 32 pipelines and subsea cables across three offshore fields. Managing Tier-1 FEED contractor, cost & schedule, risk and execution strategies on behalf of the operator.
Led qualification of the world's first 32-inch mechanically lined pipe for a major Caspian field development — full-scale reeling simulation, strain-based design and ECA aligned with DNV-ST-F101.
Delivered five offshore platforms, ~75 km of pipelines, four subsea umbilicals and two subsea skids through engineering, fabrication, installation and commissioning. Managed HDD pipeline installation and EPIC tender / award.
Engineering and qualification of CRA-lined pipelines for CO₂ transport in pre-salt offshore conditions — material selection, sour service / CO₂ integrity and long-term performance under demanding service.
Engineering and planning for a subsea field decommissioning programme — DSPM removal, 20 km of flowlines, subsea manifolds and wellheads, aligned with NOPSEMA expectations.
Pipeline Technical Authority (TA-1) accountable for the integrity of 800+ offshore and onshore pipelines — inspection strategy, pigging, anomaly assessment and fitness-for-service across the asset portfolio.
Client Site Representative supervising fabrication at major yards including McDermott Batam and Jebel Ali — load-out readiness, QA/QC, schedule and HSE assurance on behalf of the operator.
Subsea scope covering 300 km of pipelines, 150 km of umbilicals and 110 km of high-voltage subsea power cables, plus shore-crossing options (HDD, micro-tunnelling, open cut) and CO₂ pipeline study.
Engineering leadership for a patented subsea pipeline removal technology achieving >50% cost reduction and lower environmental footprint versus conventional methods — concept through third-party qualification.
Non-linear FE verification of a 32" × 12" in-line barred tee for a late-life North Sea gas pipeline. ANSYS analysis to ASME VIII Div 2 App 4 covering FAT, installation on stinger, system pressure test and 30-year operation — including structural qualification of the internal pig guide bars in F65 carbon steel at 172 barg and 145 m water depth.
HP/LP interface integrity review of super duplex 10" × 6" barred tees on a North Sea subsea manifold following gas-lift overpressure scenarios. Combined analytic checks to PD 5500 / BS EN 13445 with non-linear FE analysis and HISC evaluation per DNV-RP-F112, incorporating measured wall loss and geometry sensitivities to support safe life extension of the existing manifold.

// Leadership
Offshore engineering is relationship-driven. You are not hiring a logo — you are hiring senior practitioners with a track record of safe, commercially sound offshore delivery.
VORYX is led by a team of senior offshore engineers and project delivery practitioners with 50+ years of combined field experience across the Asia-Pacific, Middle East, Australia, Africa and European offshore basins. Our team members have delivered the full offshore lifecycle — from concept selection and FEED through EPCI execution, brownfield modification, integrity management, and end-of-field decommissioning — for national oil companies, international majors, and independent operators.
Our engineering leadership combines chartered and professional engineers with post-graduate qualifications, PMP-certified project directors, and offshore-qualified (BOSIET / OPITO) practitioners. Between them, they have served as Pipeline Technical Authority for portfolios exceeding 800 subsea pipelines, led decommissioning FEED covering 27 platforms and 32 pipelines for a major Middle East operator, delivered a world-first 32-inch cladded mechanically-lined pipe in the Caspian, and supported CCUS and CO2-injection developments in Southeast Asia and Brazil.
The team's operational DNA is drawn equally from operator technical authority roles, Tier-1 EPC and EPCI delivery, and hands-on fabrication yard leadership across Batam, Jebel Ali, Zait Bay and the Egyptian Mediterranean yards. That combination — of client-side rigour, contractor-side delivery discipline, and yard-floor practicality — is why VORYX clients receive advice that is technically robust, commercially grounded, and executable in the real offshore environment.
