Singapore bunkering firm Sinanju Tankers Holdings (Sinanju) Friday Singapore’s first bunker tanker installed with two mass flowmetering (MFM) systems for bunkering of distillates.
The Marine Pamela has been successfully tested by the MFM Working Group; it is a 2012-built 4,765 dwt bunker tanker that has been fitted with a 4-inch meter and a 10-inch meter connected to their respective piping systems.
The combination provides the vessel with a wide range of pumping rates from as low as 14 mt per hour to 1,000 mt per hour.
It ensures a stable and accurate measurement of low viscosity distillate fuels; accommodating to the delivery of small sized fuel parcels, to providing higher efficiency at faster pumping rates when receiving fuel at oil terminals.
“Sinanju has been actively involved in an industry task group set up to deliberate on acceptance test procedures for distillate MFMs since 2017,” says Desmond Chong, General Manager at Sinanju.
“We were faced with many technical challenges during the trials and we learnt that these MFMs are certainly not a simple replicate of existing MFO (marine fuel oil) MFM systems.
“The task group members working alongside with us, in particular, Metcore International, Endress+Hauser and ExxonMobil provided their expertise in metrology, flow measurement and fuels technology.
“This helped pave the way towards imminent regulatory approval for Marine Pamela to operate two MFMs for bunker deliveries, thereby establishing a new dimension in managing multiple MFMs on board bunker tankers in Singapore.”.
Darrick Pang, Managing Director at MFM bunker consultancy firm Metcore International, says it was involved in the testing of distillate MFMs on two test vessels, including Marine Pamela, to develop industry recognised acceptance test procedures and accreditation of distillate MFMs for bunker tankers.
“Having assisted over 70 bunker tankers obtain accreditation for their MFO MFM systems in Singapore and abroad, we drew on our experience in the integration of bunker tankers and meters as a complete system, with the aim of maintaining consistency and optimisation of fuel mass measurement performance,” he notes.
“Our support in the design of the dual metering system for distillates on Marine Pamela provided us with a better understanding in the behaviour of low viscosity fuel and aeration during operations which affects meter selection.
“Through the collaborative efforts of the team, we are delighted to achieve test results which are better than regulatory requirements.”
Mohamed Abdenbi, Business Process Consultant at MFM manufacturer Endress+Hauser (S.E.A), confirmed the successful tests of its 4-inch, 6-inch and 10-inch MFM systems for distillates.
“Along with this project, we are also delighted to showcase our new “dual line MFM system” on Marine Pamela,” he says.
“We are convinced it will help the bunkering industry meet the newly announced mandatory use of MPA-approved MFM systems for distillate delivery.
“Endress+Hauser is now ready to support the next phase of distillates MFM installations onboard bunker tankers and ensure that the MFM system can be easily integrated with the upcoming e-BDN project.
“We are committed in making this a success and will assist our customers meet the deadline.”
Summing up, Chong says Sinanju plans to prepare for the 1 July 2019 implementation date on the mandatory use of MFM systems for custody transfer of distillate fuels within Singapore port waters.
“With the growing demand for low sulphur distillate fuels, Sinanju will be retrofitting more than half of our fleet of 13 bunker tankers,” he says.
“Some will have distillate MFMs alongside existing MFO (marine fuel oil) MFMs, while other tankers may have different sized meters for distillates only.
“We aim to equip our vessels with a meter mix that will provide commercial flexibility and efficiency to meet the requirements of our ships’ charterers and the ships we bunker.”

Buyers can nominate deliveries on platform and plan operations together with suppliers following ‘one single truth’ concept with all players aware of what has been agreed when and by whom, says DNV spokesman.
Rotterdam’s intention to mandate the usage of MFMs goes down well with licensed bunker supplier VT Group; MFM providers supportive of move but stressed continuous monitoring is needed for optimum performance.
Cost of alternative bunker fuels, bunker operations and technology advancement are some considerations to be examined by the maritime industry, says Neo, director of SDE International Pte Ltd.
