Innospec launches Octamar™ series of additives for new blends of IMO 2020 bunker fuels

Octamar™ HF-10 Plus & Octamar™ Ultra HF both enhance the stability and compatibility of VLSFOs and hybrid fuels, company spokesman tells Manifold Times.

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.

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.

“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 ship owners 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 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.”

“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.”

Singapore: EMA, MPA shortlist two consortia for ammonia power generation and bunkering

Chosen consortia are Keppel’s Infrastructure Division and Sembcorp-SLNG, and the bunkering players in these consortia are Itochu Corporation, NYK Line and Sumitomo Corporation.





RESIZED bunker tanker singapore

The Energy Market Authority (EMA) and the Maritime and Port Authority of Singapore (MPA) on Thursday (25 July) said they have shortlisted two consortia that will proceed to the next round of evaluations of proposals to provide a low- or zero-carbon ammonia solution on Jurong Island for power generation and bunkering. 

The two consortia were selected from a total of six that were earlier shortlisted in 2023 to participate in a restricted Request for Proposal (RFP), following an Expression of Interest (EOI) called in 2022. The bids were assessed based on the technical, safety and commercial aspects of their proposals. 

The two consortium leads are Keppel’s Infrastructure Division and Sembcorp-SLNG, and the bunkering players in these consortia are Itochu Corporation, Nippon Yusen Kabushiki Kaisha (NYK Line) and Sumitomo Corporation. The two consortia will proceed to conduct engineering, safety and emergency response studies for the proposed Project.

At the next phase, we will select one of the two bidders as the lead developer of the project. The lead developer will develop the end-to-end ammonia solution comprising (i) generating 55 to 65 MW of electricity from imported low- or zero-carbon ammonia via direct combustion in a Combined Cycle Gas Turbine; and (ii) facilitating ammonia bunkering at a capacity of at least 0.1 million tons per annum (MTPA), starting with shore-to-ship bunkering followed by ship-to-ship bunkering. 

Given the nascency of the technology and global supply chains, the Government will work closely with the appointed lead developer to implement the Project. We aim to announce the lead developer by Q1 2025.

The project is part of Singapore’s National Hydrogen Strategy launched in 2022, which outlines Singapore’s approach to develop low-carbon hydrogen as a major decarbonisation pathway as part of the nation’s commitment to achieve net zero emissions by 2050.

A key thrust of this strategy is to experiment with the use of advanced hydrogen technologies that are on the cusp of commercial readiness. Ammonia is currently one of the most technologically-ready hydrogen carriers with an established international supply chain for industrial use.

“If successful, the project will position Singapore as one of the first countries in the world to deploy a direct ammonia combustion power plant and support the development of ammonia bunkering for international shipping, EMA and MPA said.

“This will help to unlock the potential of low-carbon ammonia as a low-carbon fuel.”

LNG Bunkering

China: River-sea LNG bunkering vessel named and delivered in Shanghai

The 14,000 cubic metre ship, “Huaihe Nengyuan Qihang”, was independently developed, designed and built by Hudong-Zhonghua Shipbuilding (Group) for Huaihe Energy Holding Group.





China: River-sea LNG bunkering vessel named and delivered in Shanghai

China’s river-to-sea LNG bunkering vessel, which was built locally, was named and delivered in Shanghai on Monday (19 July), according to the Shanghai Association of Shipbuilding Industry (SASIC). 

The 14,000 cubic metre (cbm) ship, Huaihe Nengyuan Qihang, was independently developed, designed and built by Hudong-Zhonghua Shipbuilding (Group) Co., Ltd for Huaihe Energy Holding Group as part of China’s "Gasification of the Yangtze River” project.

The ship is capable of travelling through the Nanjing Yangtze River Bridge all year round and has been dubbed a “Customised Yangtze River” LNG refuelling and transportation ship.

The ship is equipped with the B-type LNG containment system independently developed by Hudong-Zhonghua and authorised by a national patent.

According to SASIC, this was the first time such a system has been applied to a domestic LNG  refuelling and transportation ship, marking a major breakthrough in the B-type LNG containment system developed by China with independent intellectual property rights.

Singapore-flagged tanker “Hafnia Nile” to be moved to safe location for cargo transfer

“Hafnia Nile” and the Sao Tome and Principe-flagged “Ceres I” collided and caught fire about 55km northeast of Pedra Branca on 19 July.





Singapore-flagged tanker “Hafnia Nile” to be moved to safe location for cargo transfer

Shipowner Hafnia, the operator of Singapore-flagged tanker Hafnia Nile, is in discussion with The Maritime and Port Authority of Singapore (MPA) on a safe location to transfer the ship’s cargo, MPA said on Wednesday (24 July). 

They are also discussing towage plans for repairs to be approved by MPA.

Hafnia Nile and the Sao Tome and Principe-flagged Ceres I collided and caught fire about 55km northeast of Pedra Branca on 19 July.

“An additional tug with deep-sea towing capacity has arrived on site on 23 July 2024, joining four other tugs equipped with oil response and firefighting capabilities,” MPA said. 

In a meeting with MPA on 23 July, Hafnia informed MPA of light oil sheens near Hafnia Nile

“As part of the towage plan, Hafnia will arrange for repairs, containment and clean-up of the assessed localised seepage,” it added.

Reuters reported Hafnia stating that an initial assessment by a team of specialists conducting inspections of damaged areas of the tanker, showed Hafnia Nile's engine room had suffered damage from the fire.

Hafnia also reportedly said a salvage team has boarded the vessel and transferred equipment from one of the attending tugs on site to contain and stop any localised seepage.

Manifold Times previously reported Ceres 1 allegedly leaving the site of the collision as of 20 July and turned off its Automatic Identification System (AIS) but was believed to be in Malaysian waters.

The Malaysian Maritime Enforcement Agency (MMEA) was able to locate Ceres 1 some 28 nautical miles northeast of Pulau Tioman.
