War & Maritime Commerce: Legal Implications of Armed Conflict on Ships, Trade, Oil & Commodities : Force Majeure, Sanctions, Risk Allocation

I. Introduction: Geopolitical Conflict as a Systemic Risk to Maritime Trade

Armed conflicts, from regional skirmishes to full-scale interstate wars, constitute one of the most profound disruptors of global maritime commerce. The effects permeate every facet of shipping: vessel operations, charterparty performance, cargo safety, insurance, trade finance, commodity supply chains, and ultimately the legal architecture that governs carriage of goods by sea. When hostilities erupt, the foundational assumptions of commercial contracts are shattered. Ports close, strategic straits become perilous, insurance premiums skyrocket, and sanctions regimes multiply. This treatise authored by Dr. Shrikant Pareshnath Hathi undertakes an exhaustive examination of the legal implications of war on ships, trade, oil, and commodities, with a specialized focus on force majeure, contractual frustration, war risk clauses, sanctions compliance, and risk allocation strategies. Drawing upon English common law, US jurisprudence, Indian maritime statutes, international conventions (Hague-Visby, Hamburg, Rotterdam), and landmark arbitral awards, this article equips maritime stakeholders with the analytical tools to navigate conflict-induced turbulence.

In the contemporary era, the spectre of war in the Black Sea, the Red Sea crisis involving Houthi drone attacks, simmering tensions in the South China Sea, and the resurgence of state-sponsored naval aggression have reminded the shipping industry that peace is not guaranteed. The ripple effects extend far beyond the immediate theatre of operations: oil prices surge, grain corridors close, container shipping faces diversions around the Cape of Good Hope, and carbon-intensive detours increase emissions. For legal practitioners, the central questions revolve around the allocation of risk: Who bears the additional costs of war risk insurance? Can a charterer lawfully refuse to order a vessel into a war zone? When does force majeure suspend or terminate a charterparty? How do sanctions interact with shipping contracts, and what happens when performance becomes illegal? This analysis dissects these questions through a structured, multi-disciplinary lens.

II. The Legal Framework: International Law, UNCLOS, and Armed Conflict at Sea

The law of armed conflict at sea (sanctioned by the Geneva Conventions and customary international law) provides a baseline, but commercial shipping operates primarily under private contract law. The United Nations Convention on the Law of the Sea (UNCLOS) establishes navigational rights, but in times of war belligerent rights such as blockade, contraband interdiction, and visit-and-search can override ordinary commercial freedoms. Neutral vessels face risks of detention, requisition, or even attack. Understanding the interplay between public international law and private maritime contracts is essential. Recent state practice including the creation of naval coalitions to protect merchant shipping (e.g., Operation Prosperity Guardian) illustrates how states attempt to safeguard trade lanes, yet the legal status of such protection does not automatically relieve contractual obligations. Shipowners must balance voyage instructions with obligations of safe port under charterparties, while charterers must consider their duty not to order vessels into dangerous areas without appropriate war risk cover.

III. Force Majeure and Frustration in Maritime Contracts: Doctrinal Foundations

Force majeure (civil law concept) and frustration (common law) are the principal doctrines that relieve parties from performance when war renders contractual obligations impossible, illegal, or radically different. Under English law, a contract may be frustrated if an unforeseen event (e.g., outbreak of war, prolonged closure of the Suez Canal, imposition of sanctions) fundamentally changes the nature of the outstanding contractual rights and obligations. The landmark case of *The Evia (No. 2)* [1983] 1 AC 736 established that a time charterparty can be frustrated if the vessel is trapped in a war zone for an indefinite period. Similarly, *The Sea Angel* [2007] EWCA Civ 544 refined the modern approach, emphasising a multifactorial test: the terms of the contract, the nature of the supervening event, and the parties reasonable expectations. In voyage charters, force majeure clauses often specify that war, blockade, or acts of terrorism entitle the carrier to cancel or deviate. The absence of an express clause forces parties to rely on common law frustration a high threshold.

Force majeure clauses are increasingly sophisticated. BIMCO s Force Majeure Clause 2022 provides a modern template, defining qualifying events (including war, invasion, hostilities, terrorism) and offering relief from performance without termination. However, in volatile regions, termination rights (war cancellation clauses) are preferred, enabling owners to withdraw vessels from dangerous areas. The legal effect of force majeure under Indian law, governed by the Indian Contract Act 1872, is rooted in Section 56 (impossibility). The Supreme Court in *Energy Watchdog v. CERC* (2017) reaffirmed that force majeure must be express or implied from the nature of the contract. Given the centrality of war disruption, drafting precise clauses is not a luxury but a necessity.

IV. War Risk Clauses in Charterparties: BIMCO CONWARTIME, VOYWAR, and Safe Port Warranties

Standard war risk clauses are pivotal. BIMCO CONWARTIME 2013 (time charter) and VOYWAR 2013 (voyage charter) grant the shipowner the right to refuse orders to proceed to a war zone or to deviate to avoid danger. The clauses also allocate the cost of additional war risk insurance premiums to charterers. Under CONWARTIME, the owner is entitled to require the charterer to nominate a safe port; if the nominated port becomes unsafe due to war, the owner may demand an alternative. Failure to comply permits the owner to deviate or terminate. The jurisprudence on safe port warranties (the *The Eastern City* [1958] 2 Lloyd s Rep 127) establishes that a port is unsafe if, in the absence of abnormal occurrences, the vessel cannot reach, use, and depart without being exposed to danger that cannot be avoided by good navigation and seamanship. War adds a layer of unpredictability missile attacks, mines, or insurgency render ports unsafe. The owner is not obliged to test safety by sailing into a known war zone.

Recent conflicts have tested the interplay between war clauses and force majeure. During the Black Sea grain corridor interruptions, many charterers sought to invoke force majeure to avoid demurrage claims, while owners relied on war cancellation to withdraw vessels. LMAA awards have consistently held that if a war clause is incorporated, the contractual mechanism (notice, change of orders, cancellation) must be followed strictly. Sanctions also now interplay: if a voyage would violate sanctions (e.g., trading with sanctioned Russian entities), performance becomes illegal, terminating the contract under common law illegality principles a distinct but related ground to force majeure.

V. Effect on Bills of Lading: Carrier s Liability, Misdelivery, and Deviation

War directly impacts bills of lading: the document of title concept becomes complicated when ports are blockaded, goods are confiscated, or carriers divert to alternative discharge ports. Under the Hague-Visby Rules, Article IV(2)(f) exempts the carrier from liability for act of war . However, the exemption does not relieve the carrier from exercising due diligence to make the vessel seaworthy. If a vessel is ordered into a war zone without adequate insurance or protection, the carrier may be in breach. Moreover, deviation to avoid war is generally justifiable as a reasonable deviation under Article IV(4). Nevertheless, cargo interests may claim that the carrier should have anticipated the risk and refused the voyage. The Rotterdam Rules (not yet in force) attempt to codify liability for war, but the existing international regime relies heavily on contract terms.

In practice, shippers and consignees must ensure that bills of lading contain war risk and deviation clauses. Straight bills vs. order bills also matter: if a war intervenes and the original bill cannot be presented for delivery, carriers may deliver against indemnity, but such indemnity does not cure misdelivery if the true holder later appears. This area demands careful drafting and reliance on P&I club letters of indemnity with first-class bank counter-indemnities.

VI. Sanctions and Embargoes: The New Frontline of Maritime Law

Economic sanctions have become a primary tool of statecraft, often accompanying armed conflict. US sanctions (OFAC), EU sanctions, and UK sanctions target vessels, commodities (oil, steel, grain), and shipping companies. The proliferation of dark fleet vessels transporting sanctioned oil has led to increased scrutiny, vessel arrests, and secondary sanctions risks for financiers, insurers, and charterers. Sanctions can render performance illegal, terminating contracts by operation of law. The BIMCO Sanctions Clause 2020 allows parties to suspend or terminate the charterparty if a party or vessel becomes subject to sanctions. For commodity traders, compliance is paramount: a letter of credit may be frustrated if the underlying trade violates sanctions, and banks may refuse payment under UCP 600 Article 36 (force majeure).

VII. Insurance: Hull War, P&I War Cover, and Cargo War Risk

Marine insurance is the shock absorber of war-related losses. Standard hull policies exclude war risks, which are covered by separate war risk policies (often placed through the London market or mutual war risk associations). The Institute War and Strikes Clauses (Hulls) define war broadly to include civil war, revolution, insurrection, and capture. Premiums vary according to the Joint War Committee s Listed Areas, which designate high-risk zones (e.g., Red Sea, Gulf of Aden, Black Sea). When a vessel enters a listed area, additional premium (AP) is payable; charterparty war clauses usually require charterers to reimburse AP. P&I clubs also provide war risk cover for liabilities (crew injury, pollution, etc.), subject to sanctions restrictions. Cargo war risk insurance is separate; traders must ensure coverage is in place when shipping through conflict zones. General Average contributions may also be triggered when a vessel incurs extraordinary expenses to escape a war peril.

VIII. Oil & Commodity Markets: Disruption, Price Volatility, and Trade Re-routing

War upends commodity supply chains: crude oil and LNG tankers avoid dangerous straits, leading to longer voyages (e.g., Cape of Good Hope detour adds 10 14 days), tightening tonnage supply and lifting freight rates. Grain exports from the Black Sea, critical for global food security, become intermittent; traders invoke force majeure on purchase contracts. Metals and mineral shipping from conflict zones likewise suffers. Legal implications cascade: demurrage claims multiply, laytime calculations disrupted, and frustration claims arise for long-term COAs (Contracts of Affreightment). Commodity futures markets exhibit extreme volatility, affecting hedging strategies. For legal counsel, the challenge is to draft adaptable force majeure clauses that encompass supply chain disruption and port closures due to war or warlike actions.

IX. Judicial and Arbitral Responses: Leading Cases and Emerging Trends

English courts and LMAA tribunals have addressed war-related disputes extensively. In *The Pioneer * (2018), the Commercial Court considered whether a missile attack constituted a war risk allowing owners to refuse orders. In *The MSC Flaminia * (2022), issues of perils of the sea vs. war risk were analysed. The trend is to enforce express contractual provisions strictly while recognizing the commercial realities of volatile regions. India s High Courts, though less frequently, have dealt with war-related deviation and frustration, applying principles analogous to English law. As the 2026 Carriage of Goods by Sea Bill nears enactment, Indian law will modernize its approach, aligning with international best practices on electronic bills and the Hague-Visby regime, but war risk issues remain largely governed by contract and general maritime law.

X. Practical Risk Management: Drafting for Resilience

To withstand war-induced turbulence, stakeholders must adopt robust contractual risk allocation. Owners should insist on comprehensive war clauses (BIMCO CONWARTIME), express reimbursement of AP, and clear termination rights. Charterers should secure warranties that the vessel has appropriate insurance and that trading limits are defined. Traders must incorporate force majeure provisions covering war, hostilities, blockade, sanctions and specify consequences (suspension, extension, cancellation). Banks must ensure letters of credit incorporate UCP 600 s force majeure protections and that underlying trade complies with sanctions. This holistic approach minimizes legal exposure and ensures business continuity.
