Force Majeure in Welding and Fabrication Contracts: A 2026 Practical Guide for Gulf Oil and Gas Project Teams
Force majeure — the legal doctrine that excuses a party from contractual performance obligations when extraordinary events beyond their control make performance impossible — has moved from the small print of Gulf EPC subcontracts to the immediate operational agenda of every welding contractor, pipe fabricator, and NDE subcontractor working in the region. The US–Israel strikes on Iran on February 28, 2026, Iran’s retaliatory attacks on energy infrastructure across all six GCC states, and the effective closure of the Strait of Hormuz have together created a force majeure landscape of a scale and complexity that most Gulf project professionals have never encountered in their working careers. This article provides a practical, technically grounded guide to managing force majeure events specifically from the perspective of welding and fabrication subcontractors — the parties who face the most immediate and concrete consequences in terms of workforce mobilisation, welder certification continuity, material traceability, and the physical state of partially-completed weld joints.
This is deliberately not a purely legal article. The interaction between force majeure doctrine and the technical requirements of ASME Section IX, ASME B31.3, and the various API standards that govern Gulf oil and gas welding and fabrication creates a set of problems that neither lawyers alone nor welding engineers alone are equipped to resolve. A welding subcontractor’s lawyer may correctly identify that a force majeure event has occurred and that a notification has been validly served — but if the QA/QC team does not simultaneously document every welder’s ASME Section IX qualification status at the exact date of the FM event, the contractor will face a requalification cost bill on project resumption that was entirely avoidable with 24 hours of administrative effort at the point of evacuation.
Similarly, a welding QA manager who correctly understands QW-322 may not appreciate that their contractor’s entitlement to recover the cost of that requalification from the project owner depends entirely on whether a specific clause was negotiated into the subcontract before mobilisation. The interaction between the legal, contractual, and technical dimensions of force majeure in welding projects is the core subject of this guide, written for project managers, QA/QC leads, welding engineers, and fabrication yard supervisors who are dealing with the 2026 Gulf crisis right now.
Force Majeure in Construction and Fabrication Contracts: The Legal Framework
Force majeure (from the French, meaning “superior force”) is a legal concept that has been incorporated into virtually all major construction and engineering contract standard forms used in the Gulf: FIDIC (Red, Yellow, and Silver Books), NEC4, LOGIC (for offshore), and the various bespoke EPC contract forms used by Saudi Aramco, ADNOC, QatarEnergy, and Kuwait Oil Company. Despite appearing in all of these, the exact definition of what constitutes a force majeure event, what relief it grants, and what obligations it imposes on the parties differ significantly between contract forms and between individual project contracts.
In English law — which governs the vast majority of international Gulf EPC and subcontracts — there is no general common-law doctrine of force majeure. Force majeure is entirely a creature of contract: it applies only to the extent that the contract defines and incorporates it. This means that the exact language of the force majeure clause in the specific subcontract is everything. Two welding subcontractors working on the same project for the same principal contractor may have substantially different FM rights and obligations if their subcontract forms were negotiated differently.
The Three-Part Test for a Valid Force Majeure Event
Across all major Gulf contract forms, a force majeure event must generally satisfy three conditions before it triggers relief:
Specific 2026 FM Triggers Affecting Gulf Welding and Fabrication Projects
The 2026 Iran war has generated multiple distinct FM trigger events, each affecting different categories of welding and fabrication obligation. It is important to match the specific FM trigger to the specific contractual obligation it disrupts — a single overarching FM notification may not be sufficient if multiple distinct obligations are affected by different events at different times.
| FM Trigger Event | Date | Contractual Obligation Disrupted | Affected Parties | FM Strength |
|---|---|---|---|---|
| US–Israel strikes on Iran; Iranian retaliation on GCC facilities | 28 Feb 2026 | Site access; personnel mobilisation; production welding on affected platforms | All contractors on GCC / Iraq sites within risk zone | Strong |
| Iran closure of Strait of Hormuz; de facto blockade | 1 Mar 2026 | Pipe and consumable delivery; equipment shipment; export of fabricated modules | Procurement contractors; fabrication yards delivering into Gulf | Strong |
| QatarEnergy force majeure declaration; LNG facility shutdown | 2 Mar 2026 | All subcontracts on North Field expansion and Ras Laffan facility works | All QatarEnergy EPC and sub-tier subcontractors | Strong |
| GCC airspace closures; commercial aviation disruption | 28 Feb – ongoing | Expatriate workforce mobilisation and demobilisation by air | All contractors requiring air access to Gulf project sites | Strong |
| Red Sea shipping disruption (Houthi campaign) | Ongoing from late 2023; intensified Feb 2026 | European and Asian pipe / consumable deliveries; Red Sea route cargo | Procurement contractors; subcontractors supplying from European mills | Moderate–Strong |
| Home-country government travel bans (India, Philippines, Pakistan, Bangladesh) | Mar 2026 (varied by country) | Workforce mobilisation obligations for Indian, Filipino, and South Asian welders | Labour contractors; EPC contractors with South Asian welder workforces | Moderate |
| War-risk insurance withdrawal / premium escalation | 28 Feb 2026 | Insurance requirements for cargo and personnel in Gulf risk zone | All contractors with contractual insurance obligations for Gulf sites | Moderate |
Force Majeure Notification: The Most Critical and Most Missed Obligation
More force majeure claims fail on notification grounds than on any other basis. The overwhelming majority of Gulf EPC and subcontracts require FM notification within a defined period — typically 7 to 14 days from the date the party became aware (or should have become aware) that an FM event had occurred or was likely to affect their performance. Missing this window can be fatal to the claim, even if the underlying FM event is entirely genuine and well-documented.
For the February 28, 2026 event, the notification window for most Gulf project subcontractors closed by March 7–14, 2026. Any welding or fabrication subcontractor that had not issued a formal FM notice by that date may have lost their contractual FM protections for obligations disrupted by the initial event — though they may still be able to notify for subsequent distinct FM events (such as the GCC airspace closure, or a new home-government travel ban issued after the initial notification window).
What a Proper FM Notification Must Contain
A legally effective FM notification in a Gulf construction subcontract is not a brief email saying “we can’t work because of the war.” It is a formal contractual notice that must typically contain the following elements to be effective under standard-form contract requirements.
Identify the FM event (specific strike, blockade, GCC attack, airspace closure) by name, date, and description. State which specific contractual obligations the FM event prevents or is expected to prevent. Quote the specific FM clause reference in your subcontract. Send via the contractually required method (written notice to the named contract representative — do not rely on email unless the contract permits it). Retain proof of delivery.
Most Gulf contracts require the party invoking FM to provide regular updates on the status of the FM event, its continuing effect on performance, and the estimated duration of the disruption. Issue these on a fixed weekly or bi-weekly schedule. Include the latest available information on the specific event (conflict status, Hormuz closure update, insurance market position, government travel ban status). Failure to maintain updates can be argued as evidence that the FM event has ended.
Force majeure does not excuse a party from taking reasonable steps to mitigate the effect of the FM event. Document every mitigation step taken: alternative supply route investigations, secondary supplier quotations, workforce redeployment to non-affected projects, consumable procurement from alternate sources. A claimant who cannot show mitigation efforts is vulnerable to having their FM extension reduced or denied.
Issue a formal notice when the FM event ends or when the party can reasonably recommence performance. Simultaneously submit the quantified extension of time (EOT) claim and any cost claim permitted under the contract, supported by the contemporaneous records maintained throughout the FM period. EOT and cost claims submitted long after the FM period ends, without contemporaneous records, are routinely challenged and reduced.
ASME Section IX QW-322: Welder Certification Continuity During FM Suspension
The ASME Section IX QW-322 six-month continuity rule is the single most consequential technical code provision for welding subcontractors during a prolonged Gulf force majeure event — and it is the provision most commonly overlooked at the moment of evacuation when project teams are focused on the immediate safety of personnel and equipment. Understanding exactly how QW-322 operates, what it requires, and what it does not permit is essential for both cost management and code compliance on project resumption.
What QW-322 Actually States
QW-322.1(a) states that a welder or welding operator shall be requalified when the specific process has not been used during any period of 6 months or more. Several important technical points follow from the precise language of this provision.
Process-specific, not project-specific. The 6-month clock runs per welding process, independently. A welder qualified in SMAW (electrode), GTAW (TIG), and FCAW who has performed SMAW work on another project during the FM suspension retains their SMAW qualification but will lose their GTAW and FCAW qualifications if they have not used those processes elsewhere during the same period. This requires tracking each process independently — a general “welding activity” log is not sufficient.
No FM exception in the code. ASME Section IX makes no provision for extended continuity in the case of force majeure, government travel bans, armed conflict, or any other external event. The 6-month clock runs continuously from the date of last use of the process, regardless of the reason for the gap. This is often misunderstood: many project teams assume that an FM-related stoppage creates a code exception that does not exist.
Evidence of continuity elsewhere is acceptable. If a welder maintained continuity during the FM suspension by welding with a specific process on another employer’s project, that continuity is code-acceptable. The evidence required is a signed letter from the other employer confirming the process used and the dates of welding activity, or a weld log signed by a qualified inspector at the other project. The documentation must specifically identify the process by AWS/ASME designation (e.g., “GTAW in accordance with ASME Section IX”) — a general statement that “welding was performed” is not sufficient.
Managing the QW-322 Clock During FM Suspension
On the day of evacuation, pull a complete copy of the welder qualification register showing each welder’s name, ID, qualified processes, and the date of last recorded welding activity for each process. This snapshot is the baseline from which the 6-month continuity clock is measured. If this record is not taken at evacuation, it must be reconstructed from welding logs and NDE inspection records — a time-consuming exercise. Store this snapshot in a cloud-accessible location, not only on site-based servers.
For each welder and each qualified process, add 6 months to the date of last activity recorded at evacuation. The resulting date is the requalification trigger — if the welder has not welded with that process before this date, their qualification lapses. Build a simple spreadsheet or register tracking this. Flag any welder-process combination whose trigger date falls within the expected FM suspension period — these are the welders who need proactive management.
Contact demobilised welders every 2 months during the FM suspension period. Ask specifically whether they have welded with their qualified processes elsewhere, and if so, collect employer confirmation letters and weld log copies. File these against the welder’s record immediately. This proactive approach converts what would otherwise be a mass requalification test on project resumption into a much smaller set of genuinely lapsed welders who could not find work elsewhere during the conflict period.
As soon as a resumption date becomes foreseeable, schedule requalification tests for all welders with confirmed lapsed qualifications. Tests must use the qualified process under the same essential variable conditions as the project WPS (P-number, F-number, thickness range, position). For sour service piping applications, consider testing all welders regardless of continuity status to establish a documented current skill baseline. Allow at minimum 3 weeks for testing, test coupon destructive examination, and issue of updated qualification records before the first production weld on resumption.
Material Traceability Obligations During FM Disruptions
ASME B31.3 Para. 306.1 imposes an unbroken material traceability obligation on all pressure-boundary pipe and fittings: heat number identification must be maintained continuously from mill receipt through to final installation, and every segment of pipe used in a pressure system must have its heat number cross-referenced to a certified mill test report (MTR) on file. This obligation does not pause during a force majeure event. The practical challenge is that the physical conditions of an emergency evacuation — rushed departures, unmanned storage yards, extended periods of unattended material in a hot and humid Gulf environment — create multiple mechanisms through which traceability can be compromised.
How Traceability Is Lost During FM Events
The most common traceability failures during Gulf FM events in 2026 are: painted stencil heat numbers on pipe bores fading or washing off in stored pipe bundles exposed to rain or humidity; spray-painted end markings on fittings degrading in direct sun over a 3–6 month storage period; pipe bundle ties and colour-coded end caps becoming separated from their bundles when material is moved by site security or maintenance staff during the unattended period; and paper MTR files stored in site offices being damaged or destroyed if the office is hit by blast, fire, or weather during the suspension. Electronic document systems are not immune if site servers lose power and backup protocols were not established before evacuation.
- Cloud backup of all MTRs completed before site departure
- Photographic survey of all received materials showing heat number markings
- Pipe ends sealed with weather-resistant plugs; heat numbers re-stencilled with paint pen
- Partially fabricated assemblies locked in container with joint hold notice attached
- Formal material hold notice issued covering all material received but not yet installed
- PMI gun used to spot-check all alloy materials before departure, records saved to cloud
- MTRs on paper only; site office inaccessible or damaged — records lost
- Pipe stored in open yard; stencils unreadable after 6 months sun and humidity
- Material moved by security staff; bundles separated from end-cap labels
- No photographic baseline of received material heat numbers taken at evacuation
- Alloy pipe cannot be positively identified — entire lot treated as suspect
- Result: PMI testing of all suspect material; potential rejection and replacement
Recovering Traceability at Project Resumption
Where traceability has been compromised during the FM period, the recovery procedure under ASME B31.3 is well-established but costly. Any pipe or fitting whose heat number identification cannot be positively confirmed must be treated as unidentified material. The options for unidentified material are: reject and replace; or test to confirm properties (chemical analysis, tensile and hardness testing) sufficient to assign the material to a specification, record the test results in lieu of the original MTR, and obtain engineering approval for use. The testing route is feasible for carbon steel line pipe but becomes progressively more expensive and complex for alloy piping grades like P91 and P22, where full chemistry and elevated-temperature tensile testing is required to confirm the grade.
Incomplete Weld Joints at FM Evacuation: Documentation, Protection, and Resumption
Few integrity challenges on a welding project are more consequential than a weld joint that was started and not finished. An incomplete weld — particularly one where the root pass and hot pass have been deposited but the fill and cap passes have not — creates a set of risks that are absent from both a fully completed and fully un-started joint. The root pass, once deposited and not subsequently protected and completed, is exposed to the atmosphere and to the aggressive Gulf marine environment for the entire duration of the FM suspension. Understanding what happens to an incomplete joint over a months-long suspension, and what must be done to assess it before completion can resume, is essential for both code compliance and weld quality.
What Happens to an Incomplete Root Pass During an Extended Suspension
A partially-completed weld joint in a Gulf outdoor environment over a 3–6 month suspension will undergo the following deterioration sequence. Within the first weeks, atmospheric moisture penetrates the gap between the deposited root pass and the parent metal in the joint preparation, initiating surface oxidation and scale formation on the joint walls. Chloride ions from the marine atmosphere deposit on the root pass surface and in the joint preparation. After 2–3 months, rust scaling is visible on the joint preparation walls and the surface of the root pass. After 4–6 months, in severe cases, pitting corrosion is initiated on the root pass weld toe and on the fusion faces of the joint preparation — the exact locations where subsequent weld passes must achieve full fusion.
The implication for resumption is clear: a root pass that has been exposed for more than a few weeks in a Gulf outdoor environment cannot simply be cleaned and continued. The joint must be fully inspected, and in most cases, the root pass must be removed and the joint restarted from the beginning. Continuing fill passes over a corroded root pass will result in lack of fusion, slag inclusions, and porosity at the root — defects that will be detected by radiographic or ultrasonic examination and will require repair, ultimately costing more time than a clean restart from the beginning.
Incomplete Weld Documentation at FM Evacuation
- Photograph every incomplete joint with job number, joint reference number, and date visible in the frame
- Record the pass sequence completed (e.g., “root and hot pass deposited by Welder ID WX-042, GTAW process, WPS-12 Rev.3”) on the weld traveller
- Record the pass sequence not yet completed and the number of passes remaining
- Cover all open joint preparations with moisture-resistant polyethylene tape or temporary backing plates — do not leave bare metal exposed
- Issue a formal weld hold notice for each incomplete joint, referenced to the weld map joint number
- Record the welder ID, process, and WPS for the passes already deposited — this is needed to trace the qualification applicable to the completed portion on resumption
- For sour service joints: apply desiccant sachets inside the temporary joint cap and seal with moisture-resistant tape before departure
Contract Clause Strategy: What to Negotiate Before Mobilising to a High-Risk Zone
The most effective risk management for a welding or fabrication subcontractor operating in a high-risk zone is not reactive — it is the negotiation of appropriate contract clauses before mobilisation. The current Gulf crisis has revealed, painfully and expensively, the gaps in standard-form EPC subcontracts when applied to a genuine force majeure event of this scale. The following clause provisions represent the minimum that a welding subcontractor should negotiate before signing a subcontract for any Gulf project where significant geopolitical risk exists.
Recovery Planning: Getting the Welding Programme Back on Track
When a force majeure event ends — or when a project resumes under a negotiated restart agreement — the welding subcontractor faces a compressed recovery schedule under significant commercial pressure. Project owners and principal contractors will want to see production welding begin as quickly as possible. The QA/QC and welding engineering team must resist the pressure to shortcut the recovery process in a way that creates code non-conformances or quality problems that will require expensive rework later. A structured recovery plan, issued before resumption begins, is the most effective tool for managing this tension.
