How the Iran–Israel War Is Disrupting Oil & Gas Projects: Impact on Welding, Fabrication & Piping Industry (2026)
The Iran–Israel conflict, which escalated sharply through 2024 and into 2025–2026, has become one of the most consequential geopolitical disruptions to the global oil and gas construction sector in a generation. For welding engineers, fabrication project managers, and piping specialists working on EPC contracts across the Middle East and beyond, the conflict has translated into a cascade of practical challenges: delayed material deliveries, spiking consumable prices, suspended workforce mobilisations, and force majeure invocations across dozens of active capital projects. This article examines the specific mechanisms through which the conflict is reshaping the welding and fabrication industry, and what project professionals can do to manage the associated risks.
The region directly affected — stretching from Iran’s South Pars gas fields through Iraq, the Persian Gulf, and the Strait of Hormuz — accounts for a disproportionate share of global hydrocarbon production and the infrastructure investment that supports it. Any sustained instability here reverberates through every segment of the oil and gas capital project supply chain: pipe mills, electrode manufacturers, inspection agencies, offshore heavy-lift vessels, and the thousands of specialised welding contractors who mobilise into the region each year. The 2026 picture is one of significant disruption layered onto an already tight global market for skilled TIG welders and qualified SMAW welding personnel.
This analysis covers the key dimensions of impact: regional project activity, Strait of Hormuz logistics risk, supply chain fragility for critical welding consumables and specialty steels, workforce deployment challenges, material cost escalation, ASME code compliance considerations when projects are relocated or delayed, and which alternative fabrication regions are absorbing diverted work. A closing section on risk management provides actionable guidance for project teams in the current environment.
Regional Overview: The Geopolitical Context for Oil & Gas Projects
The Iran–Israel military confrontation — including missile exchanges, drone campaigns, and proxy operations through Lebanon, Yemen (Houthi-controlled areas), and Iraq — has created a ring of elevated risk around the Persian Gulf and southern Red Sea. For oil and gas project sponsors and EPC contractors, this risk ring overlaps almost perfectly with one of the world’s most capital-intensive construction zones.
Iran itself holds the world’s second-largest natural gas reserves and fourth-largest proven oil reserves. Despite being under longstanding international sanctions that have already constrained Western investment, substantial domestic and China-backed project activity continues. The South Pars/North Dome gas field — the largest natural gas field in the world, shared with Qatar — remains an active site of pipeline, compression, and LNG-adjacent infrastructure investment by National Iranian Oil Company (NIOC) and its affiliates. The ongoing conflict has reduced the pool of available international subcontractors willing to operate in-country and has disrupted the supply of specialty alloy tubulars and creep-resistant P91 piping into these projects.
The Gulf Cooperation Council (GCC) states — Saudi Arabia, UAE, Kuwait, Qatar, Bahrain, and Oman — are geographically close to the conflict zone but have thus far remained outside active hostilities. However, they have not been immune to the consequences. Saudi Aramco’s capital expenditure guidance has been revised downward for the second consecutive year, partly reflecting geopolitical risk adjustments. In Qatar, the LNG expansion programme (North Field) has been buffered by its long-term contract structure, but logistics disruptions in the Red Sea have added cost and delay to equipment deliveries. UAE fabrication yards at Jebel Ali and Abu Dhabi have seen heightened security protocols and slower vessel turnaround times.
Iraq: A Frontline for Project Uncertainty
Iraq presents the sharpest convergence of ongoing project activity and direct conflict-zone proximity. The country’s southern oil fields — operated partly by international companies including TotalEnergies, BP, and ExxonMobil — have been the site of intermittent militia attacks on contractor facilities since 2019, a trend that has intensified since 2024. Several midstream pipeline upgrade and gas compression projects in Basra Province have experienced repeated suspension-and-restart cycles as security assessments are revised. This has forced project engineers into a documented practice of “conditional WPS suspension” — formally pausing welding procedure qualification activities and welder certification renewals pending stable site access, which itself creates compliance documentation challenges under ASME Section IX continuity requirements.
Supply Chain Disruptions: Pipes, Fittings, and Welding Consumables
The welding and fabrication supply chain for oil and gas projects is more geographically concentrated than most project managers appreciate. A significant proportion of the seamless pipe, alloy fittings, and specialty welding consumables used on major EPC projects in the Gulf either originate in, transit through, or are processed in regions directly affected by the current conflict and its secondary effects on shipping lanes.
Seamless Pipe and Pressure Vessel Plate
A majority of high-pressure seamless pipe used in Gulf oil and gas projects — typically to ASTM A333 (low-temperature), ASTM A335 (alloy, including P9, P11, P22, and P91 grades), and API 5L (line pipe) — is sourced from European, Japanese, South Korean, and Indian mills. The delivery route for the European and some Asian supply passes through either the Suez Canal/Red Sea corridor or around the Cape of Good Hope. Since the escalation of Houthi attacks on commercial shipping in the Red Sea beginning in late 2023, most cargo insurers have required vessels to reroute via the Cape of Good Hope, adding 10–18 days of transit time per voyage and increasing freight costs by 30–70% for this route.
For P91 and P22 alloy piping — used in high-temperature, high-pressure service such as gas turbine exhaust headers, reformer piping, and steam generation — the combination of limited global supply sources and extended transit times has created a near-critical procurement situation on several Gulf and Iraqi projects. Mill lead times that were 16–20 weeks pre-conflict are now running at 28–36 weeks at some mills, and price premiums of 20–30% above pre-2024 benchmarks are being quoted.
Welding Consumables: Electrodes, Wire, and Flux
Welding consumables represent a smaller proportion of project cost but are a critical-path item: without the correct approved consumable in stock, no welding proceeds. Several specific categories face acute pressure in the 2026 market.
| Consumable Category | Typical Application | Supply Risk Level | Estimated Price Change (vs. 2023) | Primary Cause |
|---|---|---|---|---|
| SMAW electrodes — low hydrogen (E7018, E8018) | General structural, pressure piping | Moderate | +12–18% | Energy cost inflation, freight increases |
| SMAW — high-alloy (E9018-B3, E9015-B91) | P22, P91 pressure piping | High | +25–35% | Alloy raw material shortages, limited source mills |
| TIG wire — stainless (ER308L, ER316L, ER2209) | Stainless, duplex piping systems | Moderate | +15–22% | Nickel price volatility, Red Sea freight |
| SAW wire + flux — submerged arc | Heavy plate fabrication, vessels | Moderate | +10–15% | Flux raw materials from affected sourcing regions |
| Shielding gases — argon, helium blends | TIG and MIG welding, purging | High | +20–40% | Gulf processing plant disruptions, cylinder logistics |
| Backing gas purging kits | Stainless, duplex root pass purging | Low | +8–12% | General inflation; limited direct conflict impact |
Shielding gas availability deserves special attention. Argon and helium for GTAW/TIG welding operations and for purging duplex stainless steel and austenitic stainless pipe systems is sourced regionally in the Gulf from air separation units associated with petrochemical complexes. Where these complexes are affected — directly or through a disruption to their own supply inputs — local shielding gas availability drops sharply, forcing projects to import cylinders at high cost and with extended lead times.
Project Delays, FID Deferrals, and Contract Force Majeure
Final investment decisions (FIDs) represent the moment at which project sponsors formally commit capital to a project and authorise EPC contract execution. In the current geopolitical environment, a pattern of sustained FID deferral is emerging across a specific category of Middle East oil and gas projects — those with significant above-ground infrastructure in proximity to conflict zones, or those dependent on Iranian gas feedstock, or those requiring significant imported specialist equipment through affected shipping routes.
Force Majeure: Implications for Welding and Fabrication Contracts
Force majeure (FM) clauses in EPC and subcontract agreements allow parties to suspend or modify performance obligations when extraordinary events outside their control prevent contract performance. The Iran–Israel conflict and the associated Houthi Red Sea campaign have both been cited in FM notices issued by major contractors and subcontractors operating in the region. From a welding and fabrication subcontract perspective, several specific FM complications arise.
First, material non-delivery. Where pipe or consumable deliveries are delayed by Red Sea rerouting, the question of who bears the cost is determined by the Incoterms agreed in the procurement contract and whether an FM event has been validly notified. Many older EPC subcontracts in the Gulf used Incoterms 2010 CFR or CIF terms without a robust FM schedule, creating disputes over who carries the cost of the additional 18-day Cape voyage.
Second, welder and inspector mobilisation. Several projects have issued FM notices specifically on workforce mobilisation obligations because their insurers have declined to cover personnel entering defined risk zones. This creates a secondary compliance issue: if a welder’s ASME Section IX qualification continuity lapses during a forced demobilisation, their qualification must be renewed before they can weld code work again. Tracking and managing this across a large project workforce during an FM suspension is administratively complex.
Project Activity Scorecard: Selected Gulf and Regional Projects (2026 Status)
| Project / Country | Type | Value (USD) | 2026 Status | Conflict-Related Factor |
|---|---|---|---|---|
| South Pars Phase 11, Iran | Gas field + pipeline | ~$4.8B | Suspended | Sanctions + active risk zone; international contractors withdrawn |
| Basra Gas Company, Iraq | Gas compression + pipeline | ~$1.2B | Delayed | Site security assessments; militia activity near southern fields |
| North Field Expansion, Qatar | LNG trains + offshore | ~$28.7B | Active/Impacted | Equipment delivery delays via Red Sea; logistics cost increase |
| Aramco Master Gas Phase 3, KSA | Gas network expansion | ~$6.0B | Revised FID | Capex guidance revision; risk premium on Gulf transport routes |
| Leviathan Phase 2, Israel | Offshore gas field | ~$2.0B | FID Deferred | Direct conflict zone proximity; security of offshore platforms |
| Duqm Refinery, Oman | Greenfield refinery | ~$6.7B | Active | Oman geographically buffered; some freight cost increase only |
| ADNOC Ruwais LNG, UAE | LNG facility | ~$5.5B | Active | UAE outside direct conflict; elevated insurance cost only |
Workforce Impact: Skilled Welders, Inspectors, and Site Engineers
The skilled welding workforce — certified structural and pressure welders, TIG specialists for GTAW root pass work, SMAW welders for position work on pressure piping, and CWI/CSWIP inspection personnel — has been subjected to a dual pressure in 2026. On one hand, active Gulf projects outside the direct conflict zone are competing intensely for available qualified personnel, driving up day-rates and reducing contractor margins. On the other hand, projects in or near conflict zones are demobilising personnel, flooding the regional labour market with experienced hands who cannot find equivalent work locally.
Worker Safety and Evacuation Protocols
Several of the world’s largest EPC contractors — including those operating in southern Iraq and previously in Iranian territory — have now embedded formal conflict risk tiers into their site safety management systems. At Tier 1 (heightened watch), site safety drills, communications redundancy, and emergency evacuation planning are mandatory. At Tier 2 (elevated threat), family members of expatriate workers are required to leave the country. At Tier 3, all non-essential personnel are evacuated. Projects experiencing Tier 2 or Tier 3 triggers have seen their welding workforces reduce by 40–70% during the trigger period, creating cascading schedule impacts even if the physical site is undamaged.
Certification Continuity Challenges
Beyond the immediate safety concern, extended demobilisations create a ticking certification clock for welders whose qualifications are governed by the 6-month continuity rule in ASME Section IX (QW-322) or the 2-year renewal requirement under AWS D1.1. Projects that are suspended for more than six months and then resume will need to either prove that welders maintained continuity through work elsewhere, or requalify personnel — a time-consuming and costly process that adds to the already lengthy project restart schedule.
Third-party NDE contractors — the inspection companies that perform radiographic, ultrasonic, and magnetic particle testing on welds — have similarly been affected. Several Gulf-based TOFD and phased-array UT specialist companies relocated key equipment and personnel away from conflict-adjacent areas in 2024–2025, concentrating their resources in UAE and Qatar and reducing availability for Iraq and Saudi borderline-risk projects.
Material and Consumable Cost Escalation: A Detailed View
The cost environment for welding materials on Middle East oil and gas projects has shifted materially since the pre-conflict baseline of 2022–2023. Three independent mechanisms drive cost escalation: commodity raw material prices, logistics and freight costs, and war-risk insurance on cargo.
Nickel, Chromium, and Molybdenum: The Alloy Input Chain
High-alloy consumables used for stainless steel and creep-resistant piping applications — duplex stainless steel wires like ER2209, austenitic consumables like ER316L, and Cr-Mo consumables like E9015-B91 for P91 piping — depend on nickel, chromium, and molybdenum as primary alloying elements. Nickel prices on the LME have seen increased volatility since 2022, driven partly by Indonesia export policy changes and partly by energy market uncertainty. The Iran–Israel conflict adds a layer of risk premium uncertainty, particularly for molybdenum, significant quantities of which originate in Iran.
| Raw Material | Key Use in Welding Consumables | Iran-Sourced Share of Global Supply | Price Impact (2024–2026) |
|---|---|---|---|
| Molybdenum (Mo) | P91, P22, low-alloy CrMo electrodes | ~5–8% | +15–25% |
| Chromium (Cr) | Stainless, Cr-Mo consumables | <2% | +5–10% |
| Nickel (Ni) | Stainless, duplex, Ni-alloy consumables | Negligible (Indonesia dominant) | +12–18% (LME volatility) |
| Iron ore / steel scrap | Base metal for all carbon steel consumables | <1% | +4–8% |
| Argon gas | TIG shielding, purging | ~12–15% regional supply | +20–40% |
The carbon equivalent (CE) of steel used in structural weldments is directly influenced by the availability and price of manganese, chromium, and molybdenum. Procurement teams specifying material grades should be aware that some mills are offering substitutions that, while nominally within ASTM specification, may have different CE profiles requiring preheat recalculation. Always request certified mill test reports (MTRs) and verify CE values against your approved WPS preheat requirements before accepting material to site.
Codes and Compliance Challenges During Conflict-Driven Project Disruptions
Oil and gas projects in the Gulf operate under a layered code framework: ASME B31.3 or B31.4/B31.8 for process and pipeline piping, ASME Section VIII Division 1 or 2 for pressure vessels, API 650/620 for storage tanks, and ASME Section IX for welder and procedure qualification. Each of these codes imposes continuity and traceability obligations that become particularly challenging to maintain during conflict-driven project suspensions and logistics disruptions.
Material Traceability Under ASME Section II and B31.3
ASME B31.3 requires that all pressure-boundary materials be identified by material specification, grade, and heat number throughout the fabrication and installation cycle. Where materials are held at a port or warehouse for extended periods due to shipping disruptions, the risk of documentation loss, marking degradation (paint stencils fading, heat stamps on pipe becoming unreadable), or physical intermingling with non-conforming material increases. Projects should implement enhanced hold-point inspection of all material delivered after extended logistics delays, including independent re-verification of heat numbers against MTRs before any welding begins.
P-Number and F-Number Qualification Gaps
When a project is relocated to an alternative fabrication yard — for example, from an Iraqi yard to an Indian or Singaporean facility — the welder qualification records qualified at the original site do not automatically transfer. The P-Number and F-Number grouping system in ASME Section IX means that a welder qualified on P-1 (carbon steel) at one facility can weld P-1 material elsewhere, but any equipment-specific or joint-specific qualifications tied to the original facility’s registered WPS/PQR set may need to be re-established. This is particularly relevant for specialised joints such as tube-to-tubesheet welds and dissimilar metal joints.
NDE and Third-Party Inspection Access
Third-party inspection and NDE activities — including radiographic testing (RT), ultrasonic testing (UT), and PWHT documentation — may be interrupted by conflict-zone evacuations. Approved inspection agencies may demobilise personnel before all inspection work is complete, creating a situation where welds have been deposited but not formally accepted. Under ASME Section V and the inspection hold-point requirements of most quality management plans, welding may not continue past a mandatory inspection hold point until the inspection is formally completed and accepted. Projects in this situation should document all welds held awaiting inspection separately, ensure they are not disturbed, and re-engage the inspection agency as soon as conditions allow rather than proceeding on a “verify later” basis.
Alternative Fabrication Regions Absorbing Diverted Work
Not all the news from the 2026 oil and gas construction market is negative. Geopolitical disruption in the Middle East has created significant opportunity for fabrication yards and engineering companies in South and Southeast Asia, the Americas, and non-Gulf MENA states.
India: The Largest Direct Beneficiary
India’s fabrication and piping industry — anchored in hubs at Hazira (Gujarat), Dahej, Vizag, and Chennai — has seen a measurable increase in project award activity linked to Gulf project risk relocation. India’s SMAW and GTAW-qualified workforce is large and cost-competitive, and its proximity to Gulf delivery routes makes it an attractive alternative fabrication base. Indian fabrication yards now hold ASME “U” and “U2” stamps and are pre-qualified with major international inspection agencies, making compliance-based objections to Indian fabrication harder to sustain.
India’s domestic oil and gas sector is also experiencing an investment surge as global energy security concerns prompt diversification away from Middle East supply. The new pipeline network connecting eastern India, the Bengal and Odisha LNG import terminals, and the Kochi-Koottanad-Bangalore-Mangaluru pipeline are all active. This domestic demand competes for the same pool of qualified P91 and alloy-piping specialists who might otherwise be attracted to Gulf projects, keeping skill premiums elevated across the board.
South Korea and Singapore: High-Complexity Fabrication
For the most technically demanding work — offshore modules, LNG cryogenic equipment, high-pressure reactor vessels — South Korea and Singapore remain the preferred alternative to Gulf fabrication. Korean yards at Geoje (Hyundai, Samsung) and Singapore’s Sembcorp and Keppel Marine facilities have seen increased inquiry levels for Gulf-diverted work. Costs are higher than Indian alternatives, but the technical depth, existing code qualifications, and established relationships with major international inspection agencies make them highly competitive for premium applications such as sour service piping systems and high-alloy pressure vessels.
Southeast Europe and Turkey
Turkey’s fabrication sector — particularly in the Istanbul, Kocaeli, and Izmir industrial zones — has historically served as a fabrication hub for European and Middle East oil and gas projects. The Turkish lira’s continued depreciation has kept Turkish fabrication cost-competitive despite general inflation. With Red Sea shipping disrupted, Turkey’s geographic position — accessible via the Mediterranean without transiting affected corridors — gives it a logistical advantage for European-owned Gulf projects where Mediterranean port access is available.
Risk Management Guidance for Welding and Fabrication Project Teams
The following recommendations are directed at welding engineers, QA/QC managers, procurement teams, and project managers working on oil and gas projects that are directly or indirectly affected by the Iran–Israel conflict and the associated regional disruption.
Procurement and Supply Chain
- Conduct a sourcing origin audit for all critical welding consumables and piping materials during the FEED stage. Identify any items sourced through or from affected regions and establish alternative supply chains with pre-qualified second sources.
- Build a minimum 12-week rolling buffer stock of critical consumables (high-alloy electrodes, argon/helium cylinders, proprietary flux types) at site or in a secure regional warehouse before mobilisation of welding crews.
- Negotiate long-term supply agreements with fixed-price provisions for a defined quantity of key consumables, reducing exposure to spot-market price spikes during conflict escalation events.
- For pipe procurement, add a minimum 6-week logistics buffer to all European-origin deliveries and include Cape-of-Good-Hope rerouting scenarios in your freight contract provisions.
Contract and Legal
- Review force majeure clause language in all EPC and subcontract agreements. Ensure that Red Sea corridor disruption and conflict-zone risk zone declarations are explicitly captured within the FM definition.
- Separate material supply and labour obligations in subcontracts to the maximum extent possible, allowing material deliveries to be received at a safe third-country location pending site access restoration.
- Include war-risk insurance cost escalation in project contingency budgets at a minimum of 3–5% of logistics-related contract value.
Workforce and Certification Management
- Maintain a live register of all welders’ and inspectors’ certification expiry dates, including Section IX continuity tracking. Flag any individual whose 6-month continuity window will expire during a potential FM suspension.
- Where possible, arrange for demobilised welders to maintain certification continuity through welding qualification tests or production work at a safe alternative location, with documentation for the project record.
- Establish agreements with alternative NDE contractors in lower-risk jurisdictions who are pre-approved by the project’s AI (Authorised Inspection Agency) and can provide remote review of RT films or digital UT data if site access is restricted.
Material Traceability
- Implement enhanced material receiving inspection for all deliveries arriving after extended logistics delays: physically verify heat numbers, re-check dimensions and hardness where practical, and segregate any material with degraded identification markings for engineering disposition before welding.
- Maintain digital copies of all MTRs and material certification documents in a cloud-accessible document management system that is not dependent on site-based servers, ensuring continuity of traceability records if a site is evacuated.
