Innospec New Octamar™ Additives To Help in the Blending of Compliant Fuels


In a major development, the Colorado-based global specialty chemicals company Innospec on Tuesday (3 September) launched a new series of additives specifically developed for new blends of 0.5% sulphur limit IMO 2020 bunker fuels at the 9th Biennial Bunkering in Asia conference, reports IBC. 

About the New Additives

The two new multi-functional additives, Octamar™ HF-10 Plus and Octamar™ Ultra HF, both enhance the stability and compatibility of VLSFOs and hybrid fuels; however, Octamar™ Ultra HF offers extra combustion improvements to aid blends with ignition issues.

Cost Effective Fuel Management Solution?

“Additive solutions for marine fuels were simply a ‘good to have’ in the past, but now with IMO 2020 around the corner we are seeing so many people open to this cost effective measure for marine fuel risk management,” Martin Chew, Marine Regional Sales Manager, Asia Pacific, told Manifold Times.

“There is no straight forward solution for the changeover of IMO 2020 compliant fuels and a chemical [additive] solution is one of the ways vessels can transit from consuming HSFO to VLSFO in a safe and predictable manner.”

According to Chew, most ship owners are aware they are not recommended to mix the new blends of IMO 2020 compliant fuels due to potential issues.

“Segregation in storage tanks is possible on larger ships with many tanks. That said, in some cases this might reduce the range of the ship. Older ships with 1 set of settling and service tanks will certainly experience co-mingling at some point of time.”, he explains.

“Properties of these new fuels (e.g. viscosity, cold flow properties, CCAI and cat fines) are too varied and everyone knows of their possible stability and compatibility issues which can actually worsen under operating conditions.”

“In the end, co-mingling cannot be avoided especially when you get another new batch of compliant fuel to go on top of an initially compliant fuel – that is where the problem comes in.”

Chew notes of field reports indicating sludging issues faced by shipowners when less than 10% of different IMO 2020 compliant marine fuel blends are mixed together.

“The reason for the large range of properties seen in IMO 2020 compliant fuels is due to refiners, who are more concerned about meeting  ISO 8217 specifications, each having different blends.”, informs Lawrence Chia, VP Sales – Asia Pacific, Performance Specialities.

Innospec Additives Eradicates Fuel Switch Issues

Innospec has been supplying additives to heavy fuel refining customers for the past 80 years.

“We are also working with a lot of refineries and we’re trying to help them to meet the specifications of IMO 2020 fuels; what we are seeing is that they are having problems with CFPP (cold filter plugging point), pour point, TSP (total sediment potential), and combustibility,” notes Chia.

“That’s why we are seeing compliant fuels produced by refiners having a wide range and much lower viscosity. As the refiners’ concern is limited to meeting the ISO 8217 specification, the potential operational issues are with the end user.”

How good are Innospec products?

“Our products [Octamar™ HF-10 Plus and Octamar™ Ultra HF] have gone through intensive R&D over the past one year where we collected close to 100 samples for testing at the refinery level.”

“We actually tested our additives on IMO 2020 compliant marine fuels and can verify these products are able to stabilise the fuels and greatly reduce the chances of operational issues when the fuels are co-mingled.”

  1. Dear Sir
    Good day
    I am from a technical team of Mercantile shipping lines Ltd who is managing 12 vessels and would like to use OCTAMAR product for incoming Sulphur Cap 2020.
    We know your product OCTAMAR BT25 is used for tank cleaning purpose respect to S2 Cap 2020 preparation.
    As we see again you are introducing new products Octamar HF-10 & Octamar Ultra HF to mitigate bad effect of instability & incompatibility , perhaps it is appreciable.
    Considering usage of all three chemicals , our question is
    01. If Octamar BT25 chemical has used for tank cleaning programe and in system , is it possible to use any of other two products .
    02. Whether all these chemical can use together for individual purpose as it stated for its function and that will not have adverse effect on engine component or will not change fuel properties.
    03. Please let us know bulk purchase process.
    04. Appreciate to get dat sheet for these chemicals, usage and dosing guidance.

    Thanks .
