In the application dossier for international convention compliance certificates for seagoing vessels including important certificates such as CLC, Bunker and WRC, a mandatory legal term that always appears is the Blue Card. Practical application of the law shows that many ship owners or vessel management units often have a serious misunderstanding, assuming that the Blue Card is a type of certificate issued by a state agency, or believing that enterprises only need to possess a regular hull insurance contract to meet the legal operational conditions.
Practice proves that the Blue Card is a mandatory document serving as a foundational legal basis for the competent authority to consider issuing convention certificates. If the Blue Card document contains discrepancies in vessel identification information, errors in the structure of legal commitment wording, or if the insurance service provider has not been approved for capacity by the state functional agency, the entire licensing application dossier of the enterprise will be rejected and required to undergo multiple rounds of supplementary explanation. The detailed analytical content below will help the transport business community clearly understand the true nature of this document, the reasons why VINAMARINE strictly requires its provision, as well as analyze in detail the most accurate dossier preparation process.
1. Legal nature and comprehensive definition of the Blue Card
For the entire legal dossier preparation process to proceed smoothly without encountering delay incidents, marine transport enterprises must correctly understand the nature and clearly distinguish the core difference between the guarantee document of the insurance organization and the administrative certificate issued by the public authority.
1.1. The legal nature is a financial security confirmation letter
Viewed from the perspective of jurisprudence and maritime practice, the Blue Card is essentially a financial security confirmation letter officially issued by commercial insurance organizations or P&I Clubs of ship owners to guarantee obligations for a specific watercraft. This document is used to prove and legally commit that the ship owning entity has successfully established a civil liability security basis in accordance with the extremely strict requirements of each international treaty. Only on the basis of this financial capacity confirmation document does the state management agency of the flag state have sufficient authority and legal grounds to consider issuing the corresponding certificate for the vessel.
1.2. The Blue Card is absolutely NOT a certificate
Enterprises operating in the transport exploitation sector must absolutely not confuse these two types of documents because they carry two completely different legal values. The Blue Card is entirely issued by economic entities in the private sector, demonstrating a civil financial guarantee commitment. In stark contrast, the certificate of compliance with international conventions is a state administrative decision document issued by the national vessel registration agency, serving as a mandatory legal document for the vessel to carry throughout its commercial trading activities at sea. In short and most simply understood, the financial security letter acts as a mandatory input condition of the dossier submission process, while the convention certificate is the final output result of the entire administrative appraisal process.
2. Why does the flag state or VINAMARINE require the Blue Card ?
The requirement by the specialized maritime state management agency system for vessel owners to submit the Blue Card is absolutely not an administrative procedure intended to cause difficulties for enterprises. This requirement stems from the following three core reasons to protect environmental security and traffic order.
2.1. Management of pollution risks and civil liability
All international conventions on maritime safety and environment revolve around controlling the absolute civil liability of vessel owners for ecological disasters. This responsibility covers areas requiring extremely costly funding including direct compensation for oil spill incidents, reimbursement costs for marine ecological environment restoration efforts, as well as the massive expenses arising from locating, salvaging and processing sunken vessels. The Blue Card helps the state and the international community ensure with certainty that the ship owner always has abundant financial resources available, guaranteed by a reputable financial institution, to fulfill the obligation of remedying consequences as quickly as possible.
2.2. The mechanism of the right to direct action
In certain specific disaster contexts stipulated by international law, individuals or organizations who are victims suffering damages have the power to initiate legal proceedings to claim direct compensation from the commercial insurance organization that issued the guarantee document without having to go through the process of suing the ship owner. Because this superior mechanism directly protects the economic interests of the nation and coastal communities, the state management agency must conduct extremely strict censorship through the appraisal of the Blue Card to ensure that the financial security is real, in a valid state and the insurance organization has sufficient global financial capacity to meet the compensation obligation.
2.3. Avoiding the risk of vessel detention and delays at ports
Allowing a situation where marine transport enterprises lack valid certificates or possess expired certificates will lead to terrible operational consequences. When state port control forces at international seaports conduct inspections and discover that the vessel does not meet the conditions, the vessel will immediately be subject to an indefinite detention measure. This detention decision will create a chain reaction, causing the vessel to delay its cargo handling schedule, violate commercial contracts, incur massive daily berth and anchorage costs and seriously degrade the commercial exploitation reputation of the enterprise in the international market.
3. The system of international conventions governing the financial security requirement
Depending on the technical design of the vessel, the nature of the transported cargo and the specific gross tonnage threshold, the financial guarantee letter will be specially designed to meet the following three key international convention groups.
3.1. The CLC Convention
This convention focuses on completely resolving civil liability issues arising from pollution incidents caused by oil carried in bulk from specialized oil tankers. In Vietnam, detailed regulations on the issuance of compliance certificates for this convention are instructed in detail in Circular 22 of 2025 issued by the Minister of Construction, officially taking effect from 30 September 2025. Under the regulation of this legal document system, transport vessels carrying over 2000 tons of oil in bulk as cargo are mandatorily required to establish a financial security mechanism to submit an application for a CLC certificate.
3.2. The Bunker Convention
Unlike the regulation specifically for vessels carrying petroleum as cargo, the Bunker Convention directly focuses on compensation liability for leakage and pollution incidents caused by bunker oil serving the operation of the vessel engine itself. This environmental protection regulation has an extremely broad scope of application, covering a variety of commercial seagoing vessel types currently operating, specifically applied mandatorily to vessels with a gross tonnage of over 1000 GT operating on international routes. Domestic vessels reaching this tonnage threshold can also voluntarily apply for the Bunker certificate to enhance their operational reputation.
3.3. The WRC Convention
The WRC Convention sets the highest legal standards regarding the responsibility of vessel owners related to all stages of locating and processing sunken property on the seabed. The focus of this convention is to ensure there are available funds to pay the extremely expensive towing and salvage invoices for sunken vessels. The mandatory tonnage threshold is usually applied to vessels with a gross tonnage from 300 GT upwards according to international practice. In Vietnam, the management of sunken property is strictly enforced according to the instructions of Consolidated Document 15 announced by the Ministry of Construction on 19 March 2026.
4. Bunker vs WRC vs CLC: Quick differences for immediate understanding
To assist legal specialists and exploitation staff of enterprises in easily navigating legal dossiers, remembering the differences among these three convention systems can be summarized through the following four core criteria.
4.1. Vessel subjects
The legal system regarding oil pollution under CLC standards leans entirely towards the management and supervision of specialized oil tankers carrying cargo in bulk. Meanwhile, the Bunker Convention and the WRC wreck removal mechanism cover a scope of application extending to almost all types of dry cargo transport vessels, container vessels and passenger vessels operating at sea.
4.2. Design GT thresholds
Each international convention possesses a completely independent measurement GT limit and management scope. The CLC convention applies regulations for cargo transport levels over 2000 tons. Meanwhile, the Bunker Convention takes the gross tonnage milestone of over 1000 GT as a mandatory condition, and the WRC Convention applies stricter regulations when expanding the management milestone to vessels with a gross tonnage of 300 GT and above.
4.3. Types of governed risks
The CLC and Bunker conventions focus entirely on paying compensation and remedying severe ecological consequences caused by oil spills into the marine environment. Completely opposite in nature, the WRC convention focuses on addressing physical risks, specifically dangerous obstacles created by the sunken vessel itself under the sea directly threatening the safety of maritime navigational channels.
4.4. Types of convention certificates
Corresponding to each specialized type of risk, the state management agency will issue a type of convention certificate with a different name and function. This leads to completely different legal wording requirements expressed on the Blue Card and the cross checking document checklist. The most important note for enterprises is that when proceeding with actual dossiers, the legal department must always carefully cross reference the specific vessel case including vessel design type, GT milestone, operating route and national registration status to accurately determine the exact type of certificate mandatorily required to be issued to avoid wasting insurance costs.
5. General procedure: From Blue Card to convention certificate
The procedure for applying for a civil liability insurance certificate against pollution incidents and sunken vessels is carried out according to an extremely strict general framework process comprising the following four basic steps.
5.1. Step one: Prepare vessel and ship owner information
The first foundational step demands absolute care and accuracy from the operational management unit. All information must be collected and presented in complete consistency with the national vessel registration certificate along with the enterprise legal dossier system. The data fields mandatorily requiring thorough checking include the name of the owning entity, the address of the main headquarters, the vessel registration port, the unique global identification number IMO and the measurement figure GT.
5.2. Step two: The insurance organization issues a standard Blue Card
Based on the foundation of internally verified legal information, the ship owner requests the insurance organization to issue a financial commitment letter. The most decisive factor at this stage is the structure of the compensation commitment wording and the consistency of information presented on the document. In cases where the insurance contract includes a reinsurance element, the ship owner has an obligation to coordinate to obtain an additional original certificate from the relevant reinsurance receiving organization for submission. Practice shows that many dossiers have been returned by state agencies simply because the guarantee letter was drafted using equivalent terminology but did not accurately meet the mandatory wording template of the convention.
5.3. Step three: Submit the application for a certificate
Once officially possessing a valid guarantee document in hand, the enterprise proceeds to submit the application dossier for a certificate in accordance with the administrative procedure process prescribed by VINAMARINE. Currently, these advanced administrative procedures can be completely carried out through direct submission, sending via public postal services, or most conveniently, using the online public service portal. The administrative fee stipulated in Circular 22 of 2025 of the Ministry of Construction is 100,000 VND for each issued certificate.
5.4. Step four: Receive the certificate and manage its validity
After the state agency completes the appraisal work, the licensing decision issuance process will take place extremely quickly, at the latest being two working days from the time the system records receiving a complete and valid dossier. The enterprise has an obligation to pay the fee, receive the result and carefully store the original or the electronic scanned copy of the certificate. The legal department of the company must establish a tracking management software system for the expiration date of the document and proactively proceed to renew the certificate before the vessel enters a periodic inspection period or moves into the jurisdictional waters of another nation.
6. What do VINAMARINE or the flag state usually check on the Blue Card ?
Upon receiving the submitted dossier from the transport company, the legal specialists of the state management agency will extremely carefully scrutinize the content of the commitment letter. This cross checking process is established to prevent all forms of commercial fraud and ensure absolute national maritime safety. The information groups always put under the strictest appraisal include the following six categories.
6.1. Vessel identification information
All core technical parameters used to identify watercraft globally must be accurately matched character by character. The official name of the seagoing vessel, the permanently unchangeable IMO identification number and the GT parameter are the first three technical elements placed on the scale for comparison with the national registry book.
6.2. Registration information
The public authority will thoroughly review the information about the current registration port printed on the guarantee document and match it with the legal registration operational status of the vessel to ensure the vehicle is operating under the supervision of a specific nation.
6.3. Owner and ship manager information
Information about the property owning entity or the company providing direct exploitation management services including the full enterprise name and the business registration headquarters address must absolutely match the national vessel registration book along with the current legal dossier system of the applying enterprise.
6.4. Guarantee validity period
The validity period of the financial guarantee commitment must be specifically noted with clear time milestones on the document and must always reflect the correct current active validity status in the most transparent way so that the state agency has a basis to set the time limit for the administrative certificate.
6.5. Wording according to the convention template
The legal phrases and compensation commitment sentence structures directed towards third parties in the document must mandatorily adhere closely to the original template standards prescribed in the annexes of the international treaty. Any changes in terminology that narrow the scope of responsibility of the insurance organization will not be accepted.
6.6. Whether the Insurer or P&I Club is approved
This is the most crucial stage to prevent national level financial risks. The state agency will evaluate whether the commercial insurance organization issuing the document is included in the approved capacity list. As of 2026, functional agencies have recognized a series of reputable insurance organizations such as Samsung Vina Insurance Company Limited, QBE Vietnam Insurance Company, Bao Minh Joint Stock Corporation, Global Insurance Joint Stock Corporation, MSIG Vietnam Non profit Insurance Company Limited and Saigon Hanoi Insurance Joint Stock Corporation. For international insurance organizations not belonging to the International Group of P&I Clubs, the applying enterprise must mandatorily attach strict credit rating explanation documents.
7. General checklist for a certificate application dossier
Depending on each specific type of convention and the internal regulations of each administrative dossier processing agency, the detailed dossier checklist may appear to have a few minor differences. However, based on the current legal system, a standard and complete administrative dossier framework always includes the following core document groups.
7.1. Mandatory dossier components
The first document acting to open the process is the original or electronic form of the application from the ship owner drafted according to the exact template prescribed by law. The second decisive document is the original or electronic copy extracted from the original ledger of the Blue Card financial security confirmation letter issued by the insurance service providing organization. The third document is a copy or electronic copy of the national vessel registration certificate to prove the legal registration status of the vessel. The fourth document is a legal authorization letter bearing the enterprise stamp if the person directly submitting the dossier is not the legal representative.
7.2. Practical tips before submitting the dossier
An extremely effective professional operation for legal specialists is that before proceeding to submit the dossier to the public service portal, perform a comprehensive data matching step on the same single page. Directly comparing the Blue Card document and the vessel registration certificate regarding information fields on vessel name, IMO number, GT parameter, ship owner name and business registration address will help completely eliminate the risk of the dossier being returned by the state agency requesting multiple rounds of correction.
8. Common errors causing Blue Card rejection and the latest administrative sanctions
A delayed dossier not only wastes the time resources of the administrative agency but also causes unpredictable consequences in terms of finance. Below are the most common technical errors leading to dossier rejection incidents and severe punitive sanctions if enterprises intentionally violate.
8.1. Missing or incorrect IMO number
The IMO identification number is a unique and permanent string of numbers attached to the life cycle of a seagoing vessel. Data entry staff writing down an incorrect IMO digit or negligently leaving this information field blank on the guarantee document is the leading cause for the automatic system of the state agency to reject the dossier right from the first screening round.
8.2. Incorrect GT or GT not matching documents
The design GT measurement figure recorded on the guarantee letter is calculated incorrectly or provides data that does not completely match the official technical figures in the registry dossier and the national registration certificate.
8.3. Incorrect owner or incorrect address
The legal entity providing an incorrect ship owner name, noting an incorrect office headquarters address or this information completely contradicting the vessel registration paper and the current enterprise registration dossier due to changing headquarters but forgetting to update with the insurance company side.
8.4. Unclear guarantee validity
The provided document does not contain specific information about the guarantee start time and end time, or the sentence structure does not reflect the correct state of the document being continuously active at the time of dossier submission.
8.5. Incorrect wording template and unapproved Insurer
The terminology system interpreted by the insurance organization deviates from the original standard template, lacking crucial compensation commitment phrases exactly according to the strict requirements of the convention. Furthermore, the enterprise intentionally submitting a guarantee letter from a foreign insurance service providing organization that has never been recognized for capacity by the national functional agency, while also failing to provide documents proving credit ratings, is also an error leading to the cancellation of dossier acceptance.
Enterprises must pay special attention that intentionally operating vessels on navigational channels while lacking valid certificates will face extremely fierce administrative penalties according to the latest regulations. Pursuant to Decree 82/2026/ND-CP officially taking effect from 04 May 2026, the state agency has raised the maximum administrative violation fine ceiling in the maritime sector to a maximum level of one billion VND for organizations. A series of functional forces are granted the authority to impose fines at this ceiling level including the Commander of the Vietnam Coast Guard, the Chief Commander of the Provincial Border Guard and the Director of the Provincial Police. Alongside the financially deterrent fine penalty, law enforcement forces also have the power to immediately apply extremely severe supplementary penalty forms such as revoking the right to use professional licenses, suspending the transport exploitation activities of the enterprise, or most heavily, issuing a decision to confiscate all exhibits and watercraft violating the law.
9. Frequently asked legal questions
With the aim of helping professional departments of enterprises grasp issues in the quickest and most accurate way, this content section will focus on resolving in depth the core questions that frequently appear in practice.
9.1. Is the Blue Card an Insurance Certificate ?
The answer from a legal perspective is certainly no. The financial security confirmation letter is merely an independent civil commitment document issued by the insurance providing organization to serve as a basis to prove financial capacity, for the purpose of applying for an administrative convention compliance certificate from the competent state management agency.
9.2. Do vessels under 1000 GT need a Bunker certificate ?
This issue depends heavily on the specific application scope regulations of the port authority of each particular nation. In the practical work of dossier review at the registration agency, processing officers usually evaluate requirements based on the design GT threshold milestone of the vessel. Vessels under the 1000 GT threshold are generally not absolutely forced according to international standards, but ship owners have full rights to request the state agency to issue a voluntary certificate if commercial partners or destination port authorities have stricter requirements than general regulations.
9.3. What do vessels from 300 GT need under WRC ?
For commercial transport vessels possessing a design GT from 300 and above, exploiting enterprises will generally be mandatorily required to carry out the entire procedure to apply for a compliance certificate according to the standards of the WRC Convention when operating within the regulatory scope of the convention. In this legal situation, the Blue Card financial security confirmation letter continues to play the role of a mandatory tool proving the financial capacity to pay salvage costs so that the state agency has a basis to carry out the licensing procedure.
9.4. What is direct action ?
Direct lawsuit initiation is an extremely specific and progressive legal mechanism allowing individuals, organizations, or governments who are victimized in certain specific disaster cases under the convention to have full rights to initiate legal proceedings claiming civil liability compensation directly against the commercial insurance organization. This mechanism completely eliminates the obligation to sue the ship owning legal entity, thereby preventing situations where ship owners disperse assets or declare bankruptcy to evade environmental compensation responsibilities.
9.5. How does P&I differ from regular marine insurance when applying for convention certificates ?
P&I Clubs are always designed associated with civil liability groups handling third party compensation risks and possess a financial commitment mechanism directly serving the application for convention certificates. Therefore, the method of expressing legal wording and the clause structure on their financial security documents will meet legal requirement standards much better compared to hull and machinery insurance contracts specialized in handling physical damages.
10. Conclusion
If your enterprise is in the process of preparing a submission dossier related to environmental pollution and sunken vessel certificates for marine transport vessels, always deeply remember the following three core risk management principles.
Firstly, the financial security document is absolutely not an administrative certificate, yet this document is the foundational condition carrying a decisive nature for the state management agency to issue a legal certificate for the operating vehicle.
Secondly, functional agencies under VINAMARINE will appraise the content of this document extremely strictly for the purpose of thoroughly managing ecological damage compensation liability risks and ensuring a solid legal basis for the direct action mechanism to operate effectively in practice.
Thirdly, inaccurately declaring vessel identification information or using incorrect legal terminology on the guarantee document is the most common reason causing the entire administrative processing procedure to be delayed and the dossier to be returned requesting multiple rounds of explanation.
The most practical advice for professional transport management units is that if you need to carry out this administrative procedure, organize a process to truly carefully review the wording structure on the guarantee letter and cross check the entire legal dossier system once before officially submitting it to the public service system. This careful censorship step will thoroughly cut down the waiting time for correction feedback from the public authority, maximally limit the risk of delaying the certificate reception schedule, avoid the danger of being fined billions of VND under the new law, thereby ensuring the watercraft always meets the highest safety conditions to weigh anchor and depart exactly according to the planned commercial schedule.
