GENCOA B 2022 is BIMCO’s standard contract of affreightment for dry bulk cargoes. It is one of two versions of GENCOA revising the latest version of the contract issued in 2004:

GENCOA A - a framework contract that can be used with different voyage charter parties for different trades; and

GENCOA B - an “all in one” contract that includes all terms and provision usually found in a contract of affreightment, both the contract terms of GENCOA A and the charter party terms that would otherwise be found in a voyage charter attached to GENCOA A.

GENCOA B 2022 – Explanatory notes


GENCOA B 2022 is a standard contract of affreightment for dry bulk cargoes. It is one of two versions of GENCOA revising the latest version of the contract issued in 2004:

GENCOA A - a framework contract that can be used with different voyage charter parties for different trades; and

GENCOA B - an “all in one” contract that includes all terms and provision usually found in a contract of affreightment, both the contract terms of GENCOA A and the charter party terms that would otherwise be found in a voyage charter attached to GENCOA A.

These explanatory notes are intended to explain the drafting team’s thinking behind some of the clauses of GENCOA B. This document is intended as a living document and when BIMCO receives questions on some of the clauses we will expand these notes.

BIMCO would like to thank the members of the drafting subcommittee for all their hard work in producing the new editions of GENCOA:

Ms Inga Frøysa, Torvald Klaveness (Chairperson)

Capt. Lin Huoping, COSCO Shipping Bulk Co 

Ms Peri Ertugruloglu, Viterra 

Mr Mike Queally, ADM 

Mr Sasha Patel, Steamship Mutual 

Mr Fulvio Carlini, FONASBA 


The charter party includes several standard BIMCO clauses (such as the Anti-Corruption Clause and the Sanctions Clause). Some of these clauses have been amended to fit a contract context. Explanatory notes for these clauses are available on the BIMCO website.

Copies of GENCOA B are available on BIMCO’s contract editing tool SmartCon. Users who obtain a copy of GENCOA B from any other source are encouraged to verify its authenticity before using it. A free verification checking tool is available on BIMCO’s website at


GENCOA B is divided into four main sections. Part I, Part II, Annex A and Annex B. Part I is used to insert the deal-specific information that has been agreed between the parties. Part II contains the standard provisions. The Annexes are optional.

Part I

Box layout

GENCOA B follows the usual pattern of BIMCO standard forms and includes a box layout format. Here the parties can enter the variable information that applies to the contract such as details of the parties, quantities, shipments, and scheduling requirements. Note that when using SmartCon the information entered in the boxes will automatically appear also in the corresponding clauses of Part II. This means, for example, that when the charterers’ spread of laydays is typed in Box 13 (ii), the corresponding subclause 7 (a) will be filled in at the same time, or vice versa.

Additional clauses covering special provisions, if necessary and agreed for a particular contract, may be added as rider clauses to the contract and should be referred to in Box 29. It should be noted that the incorporation of additional clauses, as with amendments to the standard text, may alter the balance of responsibilities and liabilities between the parties in the pre-printed form and, potentially, prejudice P&I cover.

Part I incorporates the BIMCO Authenticity Clause above the signature boxes. The purpose of the clause is to decrease the frequency of the industry’s - often unknowing - use of counterfeit copies of BIMCO forms. If one of the parties provides the contract template for negotiation and is reluctant to include this clause or wants it struck out, then this should serve as a warning that the offered contract is probably not a genuine BIMCO standard agreement.

Part II

Clause 1 - Subject of Contract

This clause sets out the core obligations of the parties. Additionally, it contains an express safe port warranty from charterers. The safe port warranty implies a safe berth warranty. The reasoning behind this is that whilst in a contract context the ports are usually named, port characteristics and circumstances may change during the contract period. The safe port warranty is often an issue for negotiation between the parties and can be amended to reflect the outcome of individual negotiations.

Clause 2 - Total Quantity/Number of Shipments

The parties need to elect whether a total volume of cargo in metric tons or a number of shipments should be performed. The parties must make a clear choice of which provision is to apply by indicating their choice in Box 9 of Part I.

Subclause (a) is a “total quantity” option allowing the parties to state a minimum/maximum amount to be carried under the contract. It is part of the negotiations to agree on the quantity. To avoid recurring disputes, as per Clause 3 the loaded quantity as stated on the bill of lading for each shipment shall apply when calculating the total quantity shipped.

Subclause (b) is a “number of shipments” option.

Subclause (c) deals with the situation when a shipment is not performed in accordance with the contract. If the contract provides for the total quantity option, the nominated quantity will be deducted from the total quantity. If the contract provides for a number of shipments to be performed, the number of shipments will be deducted.

Situations when a shipment cannot be performed are for example force majeure situations or when a shipment is cancelled because the laycan was missed.

Clause 3 - Actual Total Quantity Shipped

This clause deals with the quantity for the actual shipment loaded and referred to in the bill of lading. The actual total quantity is important in order to establish compliance with the total quantity requirement under Clause 2 (Total Quantity/Number of Shipments).

Clause 4 - First Shipment Layday and Final Shipment Cancelling Date

This clause establishes the shipment period, making it clear that the first layday of the first shipment must coincide with or be later than the date stated in Box 10, and the cancelling date for the final shipment must not be later than the end date specified therein.

Clause 5 - Quantity per Shipment

The quantity of cargo for each separate shipment is an integral part in the performance of the whole contract. It is at the owners’ option to decide on the minimum/maximum quantity per shipment within the limits stated in Box 10. This is very important for the owners to be able to nominate the performing vessels.

Clause 6 - Spread of Shipments

This is one of the core provisions of the contract as it deals with the gaps between the voyages.

The practical importance of this provision is that the parties need to know when they will be required to perform their respective obligations. For the owners, it means providing the ship. For the charterers, it means having the cargo at the port ready for loading. All this requires planning and coordination and must be done within a timeframe that is workable for both parties.

GENCOA is intended for use in a broad range of dry bulk cargo trades on a worldwide basis. It would be difficult to regulate contractually for every kind of programme of shipments and nomination of tonnage because individual requirements vary so much. Instead of incorporating alternative clauses for programming shipments, GENCOA uses the concept of “fairly evenly spread” which should be sufficient in most cases.

The reference to “fairly evenly spread” means that the parties are not tied to any specified dates. There is a significant downside to this in practice because the term is imprecise, and it is difficult to determine what are suitable intervals. We recommend that the parties consider agreeing timings setting out the preferred “quarter” or range of months during which the shipments are to be carried, wherever practicable, or even agree on schedules.

Clause 7 - Scheduling/Nomination

This clause provides a scheduling and nomination procedure for each of the shipments under the contract.

In Clause 7(a) the charterers are obliged to give the owners a notice providing an agreed spread of laydays for each shipment. If the contract provides for a range or multiple load or discharge ports, the charterers must nominate the port when declaring the laycan.

Subclause (b) dealing with the vessel’s nomination provides for options to elect. The second option under (b) (ii) provides for a further narrowing down of the laydays.

In practice, the first nominated ship will often not be the one performing the actual voyage. This process is reflected in subclause (d) which gives the owners the option to nominate another similar vessel which will be the ship performing the voyage and must meet the same requirements as the initially nominated ship

The acceptance by the charterers of the owners’ nominated vessel is dealt with in subclause (c). The principle is that if the charterers fail to advise the owners whether the nominated vessel is accepted within 24 hours of the nomination, then the vessel will be deemed to be accepted.

Clause 8 - Nomination of Discharging Port(s)

It should be noted that this Clause requires the charterers to make their declaration of discharge port or ports “so as not to delay” the vessel. The clause deliberately avoids a requirement to specify how many days’ notice, as the time required will depend on the discharge port nominated.

Clause 9 – The Voyage

This clause describes the standard obligations to be performed during an individual voyage under the contract.

Clause 10 – General Liberty

This is a clause commonly found in voyage charter parties granting the vessel the right to call at any port or ports and in any order (meaning ports of call within the context of those under the voyage charter). The wording of Clause 10 is taken from GENCON 1994, Clause 3 (Deviation) with the addition of an obligation on owners to notify charterers immediately of any deviation.

Clause 11 – BIMCO Slow Steaming Clause for Voyage Charter Parties 2012

Please see the explanatory notes for the Slow Steaming Clause here.

Clause 12 - Loading/Discharging

This clause deals with the allocation of costs and risks for loading and discharging of the cargo in subclause (a). It is based on the understanding that the charterers are responsible for these operations.

Subclause (b) is another standard provision. Depending on the type of the ship, it may be equipped with cranes. The charterers will have free use of the cranes and any breakdown of a crane will be deducted from laytime/demurrage on a pro-rata basis.

A standard stevedore damage clause can be found in subclause (c). It corresponds with subclause (b) where the charterers undertake the responsibility for stevedores.

Clause 13 - Cancellation Clause

This clause is often subject to negotiation and can be amended or deleted as per the parties’ wishes.

Clause 14 - Freight/Deadfreight

Clause 14 makes it clear that the freight rate for each voyage is determined by the rate stated in Box 14, and in Annex A in case there should be different freight rates based on different ports. The freight provisions of GENCOA are tied closely to Clause 23 (Suspension and Termination) - which is a provision not normally found in voyage charter parties. It spells out the consequences of late freight and demurrage payment in the context of the relationship between owners and charterers under GENCOA. Subclause (b) provides that the freight will be payable before breaking bulk. If the vessel is performing a short voyage, it is important to consider whether that is suitable.

Clause 15 - Bunker Price Adjustment Clause

This is the BIMCO Bunker Price Adjustment Clause 2004 adapted for GENCOA. The wording provides a template for a bunker adjustment clause which can be amended to reflect the needs of the parties and the trade. The common practice in dry bulk trades is to make a specific reference to the prices quoted by a named supplier or published index at a named port or place. This helps avoid disputes over which reference price is to be used for calculations.

Clause 16 - Notice of Readiness and Commencement of Laytime

This wording can be amended to fit with the individual contract or trade.

Clause 17 - Laytime and Demurrage Exclusions

This clause is listing events when laytime and demurrage shall not count. Again, it is suggestions only and can be amended to reflect the individual contract and is a commercial discussion. As currently drafted, the clause reflects the “once on demurrage always on demurrage” principle but this is something that is subject to negotiation between the parties. If they wish that only laytime should not count, the reference to “demurrage” needs to be deleted.

Clause 18 - Demurrage/Despatch

This clause deals with the applicable demurrage rate specified in Box 17 or Annex A, or as declared on nomination when the parties wish to agree to it separately for each shipment.

The clause distinguishes between disputed and undisputed demurrage. Undisputed demurrage is payable within 14 days after receipt of the invoice. Disputed demurrage is dealt with in subclause (c). It is important to note that the owners have no right to suspend performance or terminate the contract in accordance with Clause 23 (Suspension and Termination) for disputed demurrage.

The parties should use best endeavours to submit invoices within 30 days after completion of discharge, but provided they have indeed used their best endeavours they do not waive their rights if the invoices are not submitted within that time.

Clause  19 - Bills of Lading

Under most shipments, bills of lading or seaway bills are issued establishing contractual relationships between the parties to the bill. Subclause (b) provides for an indemnity for owners if the terms thereof are more onerous to the owners than the terms of the contract.

Clause 20 – BIMCO Electronic Bills of Lading 2014

Please see the explanatory notes for the BIMCO Electronic Bills of Lading Clause 2014 here.

Clause 21 - Lien

This is a standard provision for contracts of affreightment. The lien can be exercised for previous and completed voyages and is not limited to claims under the current voyage.

Clause 22 - Agents

The parties should fill in Boxes 21 and 22 to indicate which party is to nominate and appoint the agents at the loading and discharging ports. If no such choice is made, the default position that will apply is that the agents should be nominated by the charterers and appointed by the owners.

The party nominating the agents should be aware that the agents must meet the minimum quality standards required inter alia by the Federation of National Associations of Ship Brokers and Agents (FONASBA) or other equivalent quality standard. Information about the FONASBA Quality Standard is available here.

Clause 23 - Suspension and Termination

GENCOA includes a suspension and termination clause giving rights to both the charterers and the owners in the event the other party breaches the contract.

Subclause (a) deals with the charterers’ non-compliance with their payment obligations or failure to provide cargo for shipment.

Failure to pay freight, deadfreight, demurrage and sums due and payable is addressed in subclause (a)(i).  It applies to all outstanding sums due and payable under the contract as such and is not limited to a currently performing shipment. The charterers failure to pay “other compensation” due, covers other amounts due and payable by the charterers to the owners. These rights are not available for disputed demurrage before it has become payable in accordance with Clause 18 (Demurrage/Despatch).

If a situation arises where the charterers are in breach of their obligation to pay, the owners must issue a notice with a request to pay within the stated period. If the charterers do not pay within that period, the owners can immediately suspend performance of any or all their obligations.

The right to terminate the contract is only available once the period agreed in subclause (a)(i)(2) has lapsed.

If the charterers fail to provide cargo for an agreed number of shipments, the owners are entitled to terminate the contract unless the failure is caused by a Force Majeure Event in accordance with Clause 24 (Force Majeure) or due to owners’ breach of contract.

Subclause (b) mirrors this provision for situations where the owners are in breach of contract. It addresses the owners’ core obligation under a contract which is to nominate ships and make them available to the charterers. The clause does not refer to “consecutive” shipments and therefore means a failure to nominate the agreed number of shipments throughout the duration of the contract.

The charterers can also exercise the rights provided under this subclause if the owners are in material breach of the terms of the contract. The reference to “material breach” is an undefined term and its meaning will vary based on the individual contract terms. On a more general basis, it is intended to mean an act, omission, thing, payment, provision, obligation, or circumstance that would be of significance to both parties and which a reasonable person would consider as important to the contract. If the owners commit such a breach, the charterers are entitled to suspend performance immediately - which includes the payment of freight - and after an agreed grace period has lapsed, to terminate the contract.

Clause 24 - BIMCO Force Majeure Clause 2022

This is the BIMCO Force Majeure Clause 2022. The explanatory notes to the clause can be found here. Note that the suggested additional subclauses (h) and (i) in these notes have been added to the clause.

Clause 25 - Insurance

Setting out insurance requirements for both parties under long-term contracts has become important. The provision reflects what is required in the market.

Clause 26 - Assignment/Novation

GENCOA is intended to be a complete base contract the parties can use for a long-term contract. To protect eithers party’s interest, a party to the contract cannot be changed without the other party’s consent. The non-assigning party can only refuse to consent if it has reasonable grounds for doing so. A standard example for that is that the new company would not be as financially sound as the original party.

Clause 27 - Liquidation/Bankruptcy

Such a provision is often seen in long-term contracts of affreightment. It is important to know that it operates differently in different jurisdictions and depending on the local insolvency law, the non-liquidated/bankrupt party might not be allowed to terminate the contract because overriding local legislation might prevail. We recommend obtaining local legal advice before operating the clause.

Clause 28 - Taxes and Dues Clause

This clause is self-explanatory.

Clause 29 - Clause Paramount

This is the BIMCO Paramount Clause General 1997 with the addition of an introductory paragraph stating that the contract and all bills of lading and waybills issued under the contract shall be subject to the Paramount Clause. The explanatory notes for the clause are available here.

Clause 30 - Both-to-Blame Collision

This is the BIMCO Both-to-Blame Collision Clause. The explanatory notes to the clause are available here.

Clause 31 - Sanctions

This bespoke Sanctions Clause for GENCOA is based on the BIMCO Sanctions Clause for Voyage Charter Parties. The explanatory notes can be found here.

Clause 32 – Anti-Corruption

This is an amended version of the BIMCO Anti-Corruption Clause for Charter Parties 2015 adapted to fit a contract context. The explanatory notes to the Anti-Corruption Clause are available here.

Clause 33 - BIMCO General Average and BIMCO New Jason Clause

This clause contains the BIMCO General Average Clause, with the exception that the option to agree another place of adjustment than London has been removed. The explanatory notes to the General Average Clause are available here. The notes to the New Jason Clause are available here.

Clause 34 - BIMCO War Risks Clause for Voyage Chartering 2013 (VOYWAR 2013)

The explanatory notes for VOYWAR 2013 Clause are available here.

Clause 35 - BIMCO Ice Clause for Voyage Charter Parties 2005

The explanatory notes for the BIMCO Ice Clause are available here

Clause 36 - BIMCO Piracy Clause for Consecutive Voyage Charter Parties and COAs 2013

The explanatory notes to the Piracy Clause are available here

Clause 37 - MLC Clause

The clause sets out a warranty for the owners’ compliance with the ILO Maritime Labour Convention (MLC) 2006 for all vessels nominated under the contract.

Clause 38 – BIMCO Law and Arbitration Clause 2020

This is BIMCO’s 2020 edition of the law and arbitration clause which offers four named arbitration venues and a free choice of law and forum. When using BIMCO’s contract editing system, SmartCon, the option chosen by the parties in Box 23 will appear automatically in the body of this clause. If the parties fail to make a choice, English law and London arbitration will be the default position.

Subclause (a) determines the governing law; the place of arbitration; the applicable arbitration legislation; and the seat of arbitration (where the arbitration takes place in a jurisdiction other than the agreed place of arbitration). It is an “exclusive” arbitration agreement. This is emphasised by the addition of the phrase “referred exclusively to arbitration”.

Subclause (b) requires the parties to appoint three arbitrators but allows for a different number of arbitrators to be agreed.

Subclause (c) applies the terms (or rules) of the chosen arbitration association to the conduct of the arbitration. An appointment procedure is no longer included in the clause because the terms of the named arbitration venue contain a procedure to which parties should refer when making appointments of arbitrators.

Subclause (d) provides for the small claims procedures offered by the named arbitration association. Parties are free to decide on the maximum applicable sum for small claims, but otherwise the clause will display the default amount used by each of the named venues. If the London arbitration version of the clause is chosen, then an additional “intermediate claims procedure” provision will apply optionally.

Subclause (e) applies the terms, rules procedures of the chosen arbitration association current at the time that arbitration proceedings are commenced. This is the common approach for arbitration in London, Singapore, and Hong Kong. In New York the rules are different, and it is those current at the time the contract was concluded that will apply.

Subclause (f) addresses the correct service of arbitration notices and communications. Parties are free to serve notices by whatever effective means they choose, but if they choose email then they must provide the email address of someone authorised to receive arbitration notices (and advise the other party of any change of address during the period of the agreement). Notices are considered effectively served immediately on sending by email.

Clause 39 - Mediation/Alternative Dispute Resolution Clause 2021

This is BIMCO’s Mediation/Alternative Dispute Resolution Clause 2021. The explanatory notes to the clause are available here.

Clause 40 - Commission

This clause contains the owners’ obligation to pay commission to the broker. 

Clause 41 - Notices

The clause refers to boxes in Part I where the parties can include names and addresses for nominations/notifications by owners and charterers, respectively. The reference to “electronically” includes emails which are deemed to be received on the day of transmission.

Clause 42 – BIMCO Just in Time Arrival Clause for Voyage Charter Parties 2021

The explanatory notes for the Just in Time Arrival Clause are available here.

Clause 43 - BIMCO Standard ISM Clause for Voyage and Time Charterparties 1998

This is BIMCO’s Standard ISM Clause for Voyage and Time Charterparties 1998. The explanatory notes to the clause are available here.

Clause 44 – BIMCO ISPS/MTSA Clause for Voyage Charter Parties 2005

This is BIMCO’s ISPS/MTSA Clause for Voyage Charter Parties 2005. The explanatory notes to the ISPS/MTSA Clause are available here.

Annex A - Port and Rates

To complement relevant boxes in Part I, an optional annex has been included where the parties can include information in case of multiple ports/places and freight/demurrage/despatch rates. Separate tables have been included for loading ports/places, discharging ports/places and freight/demurrage/despatch rates.

Annex B - Requirements for Nominated Vessels

An optional annex has been included to make room for the inclusion of specific requirements for the vessels to be nominated by the owners.
