Accreditation Scheme for Bunker Suppliers

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

MPA and the Singapore Shipping Association (SSA) have together developed an accreditation scheme for bunker suppliers.

The objective of the accreditation is to recognise good bunker suppliers and deter malpractice in the industry.

The accreditation scheme was implemented on 1 June 2003, and bunker suppliers were given up to two years to attain the accreditation qualifications.

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

Accreditation Qualifications

Bunker suppliers to be accredited shall meet the following three accreditation 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 524:2006, 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 524:2006. 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.

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 TR48


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.

    3. 3rd & subsequent NC (Letter of Warning with 5 demerit points)
  • Moderate NC  – Letter of Warning with 20 demerit points
  • Serious NC – Letter of Warning with 40 demerit points for each NC.

*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 Marinet to 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.
