Please refer to the Guidelines (.pdf, 105 KB) for more information.

To apply for the licence of a new bunker tanker, refer to registering a bunker tanker.

As bunker tankers are also harbour craft, the licensing requirements for harbour craft in general are also apply.

De-bunkering operations in port can be carried out only with the express permission of the Port Master. An application for the process must be made.

Regulation 44 of the Maritime and Port Authority of Singapore (Port) Regulations 1997 states:

"No person shall cause or permit a vessel to undertake ship-to-ship transfer of bulk liquid without the written permission of the Port Master and except under such conditions as the Port Master may impose."

Pursuant to the above, the Port Master would consider granting permission to the owner, agent, master or person-in-charge of a vessel to offload her bunkers, i.e., Marine Fuel Oil (MFO), Marine Diesel Oil (MDO) and/or Marine Gas Oil (MGO), from the vessel's bunker tank(s), provided that the intended de-bunkering operation is due to any of the following reasons:

  • The vessel needs to enter a local shipyard for repairs, docking, etc.
  • The vessel received wrong grade(s) of bunker fuel from her last call to Singapore Port; and
  • Other reason(s) subject to approval by the Port Master.

In this regard, the owner, agent, master, bunker supplier, bunker craft operator or person in charge will submit a completed application form for a de-bunkering operation at least three working days before the intended date of the operation to the Standards and Investigation - Marine Fuel at the following:

The accreditation scheme for bunker suppliers aims to recognise good bunker suppliers while deterring malpractice in the industry. 

The scheme was developed by MPA and the Singapore Shipping Association (SSA) and was implemented on 1 June 2003.

Annual renewal of the bunkering licence is subject to the suppliers achieving the accreditation qualifications below. 


To be accredited, Bunker suppliers should meet the following three qualifications:

1.  Minimum Paid-up Capital

Bunker suppliers shall have a minimum paid-up of $500,000. They must have the minimum paid-up capital or more when renewing their licences.

2. Quality Management for Bunker Supply Chain (QMBS)

Bunker suppliers shall have a quality management system for bunker supply chain (QMBS). The quality management system should be based on the requirements as specified in the SS 524:2021, published by SPRING Singapore.

Bunker suppliers shall engage a certification body which is accredited by the Singapore Accreditation Council (SAC) for quality management system (QMS) to certify their compliance with SS 524:2021. An annual audit report has to be submitted to MPA before the expiry of their annual licences. The list of SAC accredited QMS certification bodies can be obtained from the SAC website.

SS 524:2021 can be purchased via the Singapore Standards eshop or by contacting:

3. Key Performance Indicators (KPI)

The objective of Key Performance Indicators (KPI) is to encourage accredited bunker suppliers to maintain a high standard of bunkering services in port so as to improve service level to customers. Bunker suppliers must satisfy the three KPIs, namely, Craft Operations Records, Bunker Supply Records and Customer Feedback Records, during the 12-month assessment period.

Each KPI will consist of the following components and weights:




Craft Operations Records(COR)

•    Collision / Crew injury  
•    Pollution to sea  
•    Compliance with bunker tanker standards 
•    Others


Bunker Supply Records (BSR)

•    Compliance with SS 600 and SS 648


Customer Feedback Records (CFR)

•    Customer feedback on every bunkering operation




Mechanism of KPI

When a bunkering licence is approved and at the beginning of every renewal of licence, a bunker supplier will be allotted 100 points for each category of KPI by MPA. The supplier will strive to maintain the points allotted during the licensing period. Additional merit points for each KPI will be allotted to a bunker supplier if it had no adverse records on each KPI at the end of the year under review. Conversely, if a supplier's performance is not satisfactory during the year, demerit points will be given, which deducts from the points allotted.

The respective demerit points and merit points for the KPI are given below.

During the licensing period, the bunker supplier shall maintain a minimum total weighted score (TWS) of 75 in order to be accredited or remain in the accreditation scheme.

*2: Bunker suppliers shall obtain from the master or chief engineer of the vessel receiving bunkers their satisfaction level of the bunkering operations. Customer’s satisfaction level on the bunker deliveries will be assessed on a scale of 1 to 5. The rating 5 denotes ‘Very Satisfied’ and the rating 1 denotes ‘Very Dissatisfied’.

Suppliers should key in the customer feedback for every bunkering operation into the MPA system when declaring their bunker operations through DigitalPORT@SGTMto MPA.

The standard format of the feedback questionnaire is as follows:


Bunker suppliers should incorporate the above standard feedback questionnaire in the Bunker Delivery Note (BDN) or stamp the  questionnaire at the back of the BDN and obtain customer feedback for every bunkering operation.
