Industry development

Balloting for ISO / DIS 8217 was completed in December 2009.

Singapore gave a disapproval vote with comments on basic on 4 items andespecially Hydrogen Sulphide(H2S) inclusion.

Singapore comment was that further deliberation at ISO level is needed to

understand what is better for the industry i.e. safe, effective and reasonable incost.

ISO / FDIS was developed after additional ISO Working Group meetings and

completed in March 2010.

ISO / FDIS has a further balloting process from 19th March 2010 to 19th May2010.

Major Technical Changes are not expected.

New ISO 8217 Standard expected to be released on 1st July 2010.

ISO 8217 FDIS : 2010

Aluminium and Silicon (Al + Si)

Present max limit 80 mg/kg.

New max limit 25 mg/kg lowest residualgrade to 60 mg/kg highest residual grades.

Reduce the risk of high level abrasive particlereaching the engines inlet.


9/21


ISO 8217 FDIS : 2010

Ash, Vanadium and Sodium

Vanadium and Ash limit reduced for most

residual grades.

New parameter Sodium Max level 100 mg/kg(50 mg/kg for RMA 10 and RME180).

Traditionally Sodium associated with saltwatercontamination.

Sodium may also originate from refineries inwhich case cannot be removed by onboardtreatment.

Contribute to post-combustion deposits.

ISO 8217 FDIS : 2010

Calculated Carbon Aromaticity Index (CCAI)

CCAI revised limit of 870 included for all RMG and RMK residual grades.The remaining residual grades have 850 to 860 as limits.

Not a new discovery

DNVPS Statistics only 0.02% of MFO 380 delivered globally exceed 870.

Annex F expanded to include alternative ignition and combustion quality test

method.

One alternative method is the IP 541 Fuel Combustion Analyser (FCA).

Clause 6.3 Annex F provides a basis for suppliers & purchasers to agree on

tighter ignition quality characteristics where the ignition quality is known to

be critical.

Calculated Carbon Aromaticity Index (CCAI)


12/21


ISO 8217 FDIS : 2010

New Distillate Grade DMZ

Viscosity 3 cSt @ 40C min limit.

Cater to engine with higher distillate min viscositylimit.

Safety issue low injection viscosity especially largemarine diesel engine not able to pick up full load.

Worst cases may fail to start during manoeuvring inport areas or congested waters.

MAN Diesel limitsthe viscosity at the

engine inlet to min. 2

cSt.

ISO 8217 FDIS : 2010

Grade changes

DMC removed replace as residual fuels RMA 10.

RMG and RMK expanded to include additional

viscosity grades.

RMF and RMH categories removed.

ISO 8217 FDIS : 2010

Amendment to Clause 5 of ISO 8217

General requirements have been expanded.

More reference to added substance which is unacceptable for use indiesel engines.

New Annex B Deleterious materials.

ISO & CIMAC initiated research on the analysis & interpretation of thechemical composition and the levels at which the materials can causeengine problem.

ISO 8217 FDIS : 2010

FAME and Oxidation Stability Test for Marine Distillates

FAME (fatty acid methyl ester) use of such biodiesel as fuel product orblend component.

Expected to increase in marine distillates.

Limited to de minimis levels.

FAME can cause problems with Oxidation Stability during long- termstorage.


16/21


ISO 8217 FDIS : 2010

Lubricity Test

Sulphur < 0.050% mass (500 mg/kg) this lubricity test is required for

distillates.

Too low fuel pump wear.

Acid Number (AN) Originally Strong Acid Number included in ISO / DIS 8217 as a test

parameter, however removed from table 1 & 2 now.

Acid Number is a new test parameter with 0.5 mg KOH/g for distillates

and 2.5 mg KOH/g for residual fuels.

ISO 8217 in general marine fuels shall be free from inorganic acids.

ISO 8217 FDIS : 2010

ISO 4259

Annex L compared to ISO / DIS 8217 FDIS now contains more thorough

and balanced reference to ISO 4259 procedures & applications.

ISO 4259 Clause 9 provides information to allow the supplier or the recipient

of fuels to judge the quality of a product with regard to the specification whena single result is available.

ISO 4259 Clause 10 provides procedure for supplier and recipient ifagreement cannot be reached on quality of fuel.

Applies to subdivisions of one representative sample.

ISO 8217 FDIS : 2010

Hydrogen Sulphide (H2S)

Singapore TC recommendation to exclude 2ppm measurement (in liquid)and focus on vapour limit for safety of shipboard personnel:

Singapore places the utmost importance on the safety of shipscrew. As such, we propose the limit for H2S in liquid should beremoved from the standard and instead be placed in the relevant

Annex, as H2S in any quantity is a health hazard and ISO 8217should not include any values that may put handlers at risk. A limit of2ppm H2S in the liquid phase does not necessarily preventdangerous levels of H2S from developing in the vapour space or inthe surrounding atmosphere.


19/21


ISO 8217 FDIS : 2010

Hydrogen Sulphide (H2S)

Threshold Limit Value (TLV) of 10 ppm H2S in vapor form is commonly

observed as a safety precaution in areas where ship crew is present.

2ppm (in liquid) to remain in new Standard but effective July 2012.

Argument for limit is to increase awareness of possible presence of H2S inmarine fuels and improve margin of safety for this toxic and flammable gas.

But challenge is H2S 2ppm(in liquid) measurement can give a false sense ofsecurity since 2 ppm in liquid may result in vapour level exceeding 200 ppmin vapour form during transportation, storage and handling.

Key issues for future

How ready is Buyer, Seller and other players in the value chain?

How will this impact bunker prices?

What is the position of other regional bunkering ports?

How should Singapore vote for this ISO 8217 FDIS?

- The TC will appreciate input before we take final vote. Formal voting closeson 19th May 2010.

- Input can be set to [email protected]
