Bunkering Standards

To ensure a robust bunkering sector, Singapore has implemented a set of bunkering standards covering documentation, equipment, procedures, quality of bunker fuel supplied and more.

A list of key standards are listed below. MPA reviews these standards from time to time to ensure its quality.

SS 648 was developed for the benefit of the bunker industry in Singapore comprising ship owners, operators, charterers, bunker suppliers, bunker craft operators and bunker surveyors and is intended to enhance the efficiency of bunkering operators and promote best practices in the measurement of bunker fuel delivered.

The purpose of this SS is to document principles, requirements and procedures in the application of mass flow metering to bunker in Singapore.

MPA has implemented the Singapore Standard for Quality Management for Bunker Supply Chain (QMBS) or SS524, the first national quality management standard for the bunkering industry. SS 524 is one of the requirements under the MPA accreditation scheme for bunker suppliers.

The SS 524 aims to establish an unbroken chain of control over the quality of bunker fuel supplied in the port. It looks into the management system for the entire bunker supply chain from product procurement to delivery of bunker to vessels in the Port of Singapore.

 

The Singapore Standard SS 648: 2019 – Code of Practice for Bunker Mass Flow Metering was launched on 7 November 2019 (“SS 648: 2019”). SS 648: 2019 is a revision of TR 48: 2015 – Technical Reference for Bunker Mass Flow Metering which was implemented on 1 June 2016 by the Maritime and Port Authority of Singapore (MPA) for the custody transfer of bunker deliveries via the mass flow metering (MFM) system to ocean-going ships in the Port of Singapore. 

TR 48: 2015 was reviewed and developed into SS 648: 2019, taking into account the operational and technical experience gained by the bunkering industry on the use of the MFM. Under the coordination of the Singapore Standards Council, the review was jointly conducted by MPA, Singapore Shipping Association (SSA), International Bunker Industry Association (IBIA), bunker suppliers, bunker craft operators, bunker surveying firms, meter vendors, National Metrology Centre and Enterprise Singapore’s Weights and Measures Office.

SS 648 : 2019 includes new requirements for multi-meter installation, enhancement of the zero verification procedure and clarity on the role of bunker surveyors. Starting from 1 May 2020, MPA will mandate SS 648 : 2019 for the custody transfer of bunker deliveries to ocean-going ships in the Port of Singapore. The existing bunkering standards, TR 48: 2015, will cease to apply by end November 2020.

The Singapore Standard Code of Practice for Bunkering by bunker barges/tankers or SS600 is applicable only in the event that there is a measuring system failure during a bunkering operation and the delivery cannot be continued, pumping shall cease immediately and the Mass Flow Meter’s totaliser readings shall be recorded in the meter reading record form. The failure shall be reported to MPA immediately. A bunker delivery note shall be prepared based on the meter totaliser reading. After obtaining permission from MPA, tank gauging in accordance with SS 600 shall be used to determine the remaining quantity to be delivered and a separate BDN shall be issued. The final quantity delivered shall be the sum of the quantities determined from the meter readings and the tank gauging recorded in the respective BDNs. SS 600 sets out the best practice for documentation and equipment requirements and, verification procedures during a bunkering operation. Covering pre-delivery, actual delivery and post-delivery checks and documentation, the SS 600 was developed for the benefit of the ship bunkering industry in Singapore comprising shipowners, operators, charterers, bunker suppliers, bunker tanker operators and surveyors.

Every bunkering operation carried out by bunker tankers to ships in the Port of Singapore must adhere to the SS 648 and 600. By carrying out the bunker delivery process in accordance with the requirements contained in this the SS 648 and SS 600, the likelihood of a bunkering dispute should be minimised.

In Singapore, all bunker suppliers and bunker craft operators are licensed by the Maritime and Port Authority of Singapore (MPA). They are required to comply with the SS 648 and 600 as a licensing requirement. Shipowners, operators and charterers should advise their officers to follow the procedures and requirements as stipulated in the SS 648 and 600 when their vessels call at Singapore for bunkering.

The “gate system” for licensing of port limit bunker tankers, spells out the requirements for bunker tankers of 600 DWT and above to operate in the Port of Singapore.

In November 2011, the Maritime and Port Authority of Singapore revised the “gate system” for the licensing of port limit bunker tankers.

Standards for port limit bunker tankers, which covers equipment, operational performance and efficiency of the bunker tankers.

All steel-hulled bunker tankers operating in the Port of Singapore must adhere to the standards for port limit bunker tankers (.pdf, 178 KB). Covering equipment, operational performance and efficiency of bunker tankers, the standards are reviewed by the Maritime and Port Authority of Singapore (MPA) from time to time.
