Operators need to understand practical risks, not just cite clauses.
Who decides, who pays, who provides data, who bears the consequences.
Concrete operational scenarios make risks tangible.
Start clearly from operational reality.
Charterparty risks were historically predominantly commercial in nature: demurrage, off-hire periods, speed warranties. With the introduction of FuelEU Maritime, the EU ETS for shipping, and the CII rating (Carbon Intensity Indicator), regulatory risks have been added that reach deep into the operational level.
The core problem lies in their multi-layered nature. A single paragraph on fuel selection can simultaneously affect ETS costs, FuelEU compliance, CII rating, and machinery reliability. A superintendent or fleet manager who reads the contractual point in isolation will miss the interactions. For example: a clause permits the charterer to bunker HFO with scrubber use. This reduces SOx emissions but increases CO2 output through the scrubber’s own energy demand. At the same time, the CII rating deteriorates, which can cause problems at the next class renewal.
Another hidden risk lies in data ownership. Many charter contracts do not regulate who “owns” the operational data generated during the charter period. The owner needs the data for their annual FuelEU submission, the charterer for their ETS cost accounting. Without an access provision, one party can pressure the other through data withholding.
Finally, the risk of time displacement. Many regulatory consequences – penalty payments, pooling settlements, CII rating adjustments – materialise months or years after the triggering operational event. A charter period may long since have ended when the financial impact becomes visible. Without a post-termination liability clause, the owner is left bearing the costs.
The key to understandable risk explanation lies in role-based logic. Rather than quoting clause text, the explanation should answer four questions: Who decides? Who provides data? Who pays? Who is liable if something goes wrong?
These four questions can be translated into a simple matrix filled in separately for each regulatory area (FuelEU, ETS, CII). The matrix becomes a communication tool between legal, commercial, and technical departments – a document all three departments can understand without needing to master legal terminology.
Working with concrete scenarios also proves effective. Rather than speaking abstractly about “compliance risks”, one describes a typical situation: “The vessel is alongside in Rotterdam for three days. The shore power connection fails. Who bears the additional emission costs?” Such scenarios make risks tangible and show where clauses apply – or do not.
In a documented case, a superintendent assumed that the FuelEU clause in their charterparty obliged the charterer to bear all compliance costs. In reality, the clause only governed data sharing, not cost allocation. The compliance costs – exceeding EUR 200,000 – remained with the owner.
In another case, a charterer communicated to their technical team that “the owner handles FuelEU”. The technical team interpreted this as licence to choose the cheapest bunkering option without regard to GHG intensity. At year-end, the compliance deficit was so large that neither borrowing nor pooling could offset it.
Both cases demonstrate: risks must not only be legally regulated but operationally understood. The clause exists in the contract; the understanding must exist in operations.
Not every stakeholder requires the same depth of explanation. For top management, the financial risk exposure suffices: “Maximum penalty risk per vessel per year: EUR X.” For the superintendent, the operational impact matters: “If the charterer bunkers VLSFO instead of B30, the GHG intensity worsens by Y%.” For the commercial manager, the negotiating position counts: “Without a cost pass-through clause, we bear the entire risk.”
The explanation should therefore exist in three versions: executive summary (one page), operational summary (three pages with scenarios), and full clause analysis (for legal). This three-tier approach ensures every decision-maker receives the information relevant to them.
The role-based matrix described above is most useful when it is introduced before a charterparty is signed, not only afterwards as a communication aid. During negotiation, each regulatory area can be walked through the same four questions — who decides, who provides data, who pays, who is liable — with the answers written directly into the clause rather than left to inference. A negotiating team that raises the data-ownership question explicitly, for example, is far less likely to end the negotiation with a fuel-selection clause that says nothing about who owns the resulting emissions data.
Using the matrix during negotiation also surfaces disagreements early, when they are still cheap to resolve, rather than months later when a dispute over cost allocation has already accumulated. A charterer and owner who cannot agree on who bears a particular regulatory cost are better served discovering that gap at the negotiating table than through an invoice dispute after the voyage has been completed. Building the matrix into the standard negotiation checklist, alongside commercial terms such as demurrage and off-hire, treats regulatory risk with the same seriousness as terms parties have negotiated for decades.
Several recurring drafting patterns weaken charterparty clauses that were clearly intended to address regulatory risk. The most frequent is vagueness about scope: a clause referring generally to compliance with applicable environmental regulations, without naming FuelEU Maritime, the EU ETS or the CII specifically, leaves room for dispute about which regime the clause was meant to cover once a cost actually arises. A second common mistake is addressing cost allocation without addressing data access, or the reverse — a party can be contractually liable for a cost it has no contractual right to verify.
A third mistake is silence on timing. Because many regulatory consequences only materialise after a charter period has ended, a clause that does not survive termination leaves the owner or charterer exposed to costs triggered by conduct during the charter but billed afterwards. Reviewing existing charterparty templates against these three failure modes — vague scope, mismatched cost and data provisions, and no post-termination survival — is a faster way to find weaknesses than rereading the entire document clause by clause.
