BIMCO charter-party clauses: the working reference

BIMCO charter-party clauses: the working reference

Built for the people who negotiate and live with fixtures (concluded charter deals): charterers, owners, operators and brokers who agree "main terms" and then fight over the detail clauses when the world changes. The BIMCO charter-party clauses that actually allocate risk — war, sanctions, ice, bunkers, emissions, hire — are scattered across the BIMCO library and standard forms. We assembled what each one does, when it bites, and whether it's a voyage or time-charter clause, into one place.

This is the "details" layer that follows the main terms in a fixture — see the end-to-end flow in How to charter a ship.

At a glance

The short version, if you read nothing else:

  • Main terms make the deal; clauses decide what it means when something goes wrong. BIMCO publishes standard, market-accepted wordings so both sides negotiate from a known baseline instead of drafting from scratch.
  • War and sanctions clauses are the escape hatches. CONWARTIME/VOYWAR let a ship refuse or deviate from war-risk areas; the BIMCO Sanctions Clause lets a party refuse a voyage/cargo that would breach sanctions — critical in the current environment.
  • The emissions clauses are new and load-bearing. The ETS, FuelEU Maritime and CII Operations clauses decide who pays the EU carbon bill and who controls the rating — the EU carbon layer in contract form.
  • Hire is protected by the anti-technicality clause. On a time charter the owner can withdraw the ship for unpaid hire, but must give an anti-technicality notice (a short cure period) first.
  • A Paramount Clause pulls the Hague/Hague-Visby Rules (the international carrier-liability regime for sea cargo) into the contract, and a General Average / New Jason clause governs shared losses — standard incorporations you'll see in almost every form.
  • Know whether a clause is a voyage or time-charter clause — many exist in both flavours (e.g. CONWARTIME for time, VOYWAR for voyage) and using the wrong one is a drafting error.

This is a practical reference, not legal advice. The exact clause wording and its latest revision always govern; consult a shipping lawyer or your P&I club (Protection & Indemnity — the shipowner's mutual liability insurer) on application.


The standard forms

A charter is usually built on a named BIMCO (or industry) pro-forma form (a standard base contract), then amended by rider clauses (the negotiated add-ons appended to it). The main ones:

Form Type Used for
GENCON 2022 Voyage General dry-cargo voyage charter (the default voyage form)
NYPE 2015 Time Dry-cargo time charter (the dominant TC form)
BALTIME Time Older dry-cargo time-charter form
BARECON 2017 Bareboat Demise / bareboat charter
SHELLTIME / BPTIME Time Tanker time charter (oil-major forms)
ASBATANKVOY / SHELLVOY Voyage Tanker voyage charter
SUPPLYTIME 2017 Time Offshore support vessels
GASVOY / GASTIME Voyage/Time Gas carriers

The recap (the broker's written summary of the agreed terms) will name the form ("otherwise as per owner's pro-forma NYPE 2015…") — which means you've agreed that entire form as amended by the recap. Read it.


Risk & security clauses

The clauses that let a party say "no" or charge extra when the world turns dangerous:

Clause Time / Voyage What it does
CONWARTIME Time Lets the owner refuse to send the ship into, or order it out of, an area of war/piracy risk; charterer bears additional war-risk premiums and crew bonuses.
VOYWAR Voyage The voyage-charter equivalent — right to refuse/deviate on war risk, with cost allocation.
BIMCO Sanctions Clause Both Lets a party refuse to perform a voyage/carry a cargo/call a port that would expose it to sanctions; unwinds the fixture without breach.
Designated Entities Clause Both Extends the sanctions protection to dealings with listed (designated) counterparties.
Piracy Clause Both Allocates the cost and routing decisions for high-risk piracy areas (armed-guard engagement is usually a separate GUARDCON contract).
Infectious or Contagious Diseases Clause Both Post-COVID wording allocating delay/cost when a port is affected by an outbreak or quarantine.
Ice Clause Both Right to refuse ice-bound ports and the cost of waiting/deviation.

War and sanctions clauses are the ones most likely to be invoked in the current market — get their cost-allocation right at fixture, not in a dispute.


Emissions & fuel clauses

The newest and most commercially live family — the EU carbon rules turned into contract mechanics:

Clause Time / Voyage What it does
ETS — Emission Trading Scheme Allowances Clause Both Shifts the cost of EU (and UK) ETS allowances to the party that controls the voyage/buys the bunkers — usually the charterer — via allowance transfer or reimbursement, with reconciliation.
FuelEU Maritime Clause Both Allocates the FuelEU compliance cost/penalty and the data needed to compute it; handles pooling and who keeps a surplus.
CII Operations Clause Time Gives the owner visibility and some control over speed/routing so the charterer's operation doesn't wreck the ship's annual CII rating; sets data-sharing and cooperation duties.
Marine Fuel Sulphur Content / Bunker Quality Clauses Both Warrant that supplied bunkers meet the applicable sulphur cap (ECA 0.10 % / global 0.50 %) and quality spec; allocate off-spec-fuel liability.
Slow Steaming / Virtual Arrival Clause Both Permits reduced speed to save fuel/emissions or to match a berth window without breaching the "utmost despatch" duty.

Because the ship's operator/charterer controls speed, routing and bunkering but the owner often holds the compliance obligation, these clauses are where the money and the blame get assigned.


Payment & performance clauses

Clause Time / Voyage What it does
Hire payment clause Time Hire is paid in advance (e.g. every 15 days). Late payment triggers the owner's remedies.
Anti-technicality (withdrawal) clause Time Before withdrawing the ship for unpaid hire, the owner must serve a notice giving a short cure period (typically a few banking days) — protects against withdrawal over a clerical slip.
Off-hire clause Time Suspends hire when the ship can't perform (breakdown, drydocking, deficiency of crew/stores) — the charterer doesn't pay for time they can't use.
Speed & consumption / performance warranty Time The owner warrants a service speed at a stated fuel consumption; a shortfall (in good weather) grounds a performance claim.
Laytime & demurrage clause Voyage The time allowed for cargo ops and the overrun rate — see the laytime & demurrage reference.
Deviation clause Both Permits justified deviation (saving life/property, bunkering) without breaching the contract voyage.

The anti-technicality point is the single most litigated TC event — a valid withdrawal is a powerful owner remedy in a rising market, but only if the notice is served correctly.


Cargo & carriage clauses

Clause What it does
Clause Paramount Incorporates the Hague / Hague-Visby (or Hamburg) Rules into the charter and bills of lading — the carrier's liability regime. (The regimes and their package limits are compared in the bill of lading reference.)
General Average / New Jason Clause Applies the York-Antwerp Rules to shared losses (jettison, salvage), and (New Jason) preserves GA contribution even where the loss stems from a navigational error.
Both-to-Blame Collision Clause Reallocates the cargo interest's recovery in a both-to-blame collision so the shipowner isn't indirectly stuck with cargo's claim. (Note: held void under US law for common carriage, so its effect depends on the governing law.)
Himalaya Clause Extends the carrier's defences and liability limits to its servants, agents and sub-contractors (stevedores, terminals).
Cargo exclusions / Solid Bulk Cargoes that Can Liquefy Clause Excludes named dangerous cargoes and manages moisture/liquefaction risk (IMSBC Group A) — the owner's protection against a cargo that can shift or liquefy.
Bill of Lading clause Governs how B/Ls are issued and that they don't impose terms beyond the charter — see Bill of lading types.

Law, arbitration & boilerplate

  • BIMCO Law & Arbitration / Dispute Resolution Clause — picks the governing law and forum. The market defaults are English law + London arbitration (LMAA), with New York (SMA) and Singapore (SCMA) as common alternatives; small claims run under the LMAA Small Claims Procedure.
  • BIMCO Notices Clause / Electronic Signatures Clause — how notices are validly given and whether e-signature binds.
  • ISPS / ISM clauses — allocate the cost and delay of security (ISPS) and safety-management (ISM) compliance.

These are "boilerplate" only until a dispute — then the law/forum choice decides where and how you fight, and under whose rules.


Who bears the cost — voyage vs time

The same event lands on different parties depending on the charter type (background in How to charter a ship):

Event Voyage charter Time charter
Extra war-risk premium (VOYWAR/CONWARTIME) Usually charterer, per clause Charterer
EU ETS allowances / FuelEU penalty Priced into freight or a surcharge Charterer (via ETS/FuelEU clauses)
Bunkers Owner Charterer
Time lost in port Charterer pays demurrage Charterer already pays hire; may claim off-hire if owner's fault
Slow/underperforming ship Owner's risk (poor TCE — the voyage's net daily earnings) Owner (performance claim / off-hire)
Sanctions making the voyage illegal Sanctions clause unwinds it Sanctions clause unwinds it

The drafting takeaway for a recap: for every risk that matters (war, sanctions, EU carbon, off-spec bunkers, performance), name the clause and the paying party — silence is where disputes are born.


For developers and operators

  • Model the cost the clause allocates: the voyage-economics calculator folds EU ETS, FuelEU, CII and the ECA bunker premium into TCE with an explicit payer input — so both sides can see their net position before agreeing the ETS/FuelEU clause.
  • Stress the demurrage exposure a laytime clause creates in the demurrage calculator before fixing.
  • Match cargo and tonnage on the chartering, cargo and tonnage boards, then negotiate the detail clauses on the agreed pro-forma.

FAQ and common confusions

Q: What's the difference between CONWARTIME and VOYWAR?
A: Same purpose — the right to refuse or deviate from war-risk areas and to pass on the extra cost — but CONWARTIME is the time-charter version and VOYWAR the voyage-charter version. Using the wrong one for the charter type is a drafting error.

Q: Which clause decides who pays the EU ETS bill?
A: The BIMCO ETS — Emission Trading Scheme Allowances Clause, which transfers the allowance cost to the party controlling the voyage (usually the charterer under a time charter), with reconciliation. FuelEU has its own clause.

Q: Can an owner really withdraw a ship for one late hire payment?
A: Yes, in principle — but a modern time charter's anti-technicality clause requires the owner to first serve a notice giving the charterer a short cure period. Withdraw without it and the withdrawal itself can be a breach.

Q: What is a Clause Paramount?
A: A clause that incorporates the Hague / Hague-Visby (or Hamburg) Rules into the charter and bills of lading — fixing the carrier's liabilities and the package/weight limitation. See Bill of lading types.

Q: What does the CII Operations Clause do on a time charter?
A: It manages the tension that the charterer controls speed and routing while the owner carries the ship's annual CII rating — setting cooperation, data-sharing and sometimes rating expectations. See the CII reference.

Q: Is off-hire the same as demurrage?
A: No. Off-hire (time charter) suspends hire when the ship can't perform. Demurrage (voyage charter) is what the charterer pays for overrunning laytime in port. Different charters, opposite directions.

Q: What law and forum govern a charter dispute?
A: Whatever the Law & Arbitration clause says — most commonly English law + London (LMAA) arbitration, with New York and Singapore as frequent alternatives.

Q: Do I have to use the exact BIMCO wording?
A: No, but starting from the current BIMCO clause is safer than free-drafting — the wordings are market-tested and courts/arbitrators know them. Amend on the record, and always use the latest revision.
