Innospec: Slow steaming offers economic and environmental rewards, but not without sacrifices

While slow steaming may help save fuel cost and lowers emissions, it may end up being a costly endeavour for ship owners. Innospec suggests looking at smart slow steaming instead, shares Nicea Ng.

Slow steaming is often considered the easiest solution for overcoming both economic and environmental challenges.

However, doing so without risking the safety and long term efficiency of ships needs careful consideration by ship owners and operators, shares Nicea Ng, Marine Technical Specialist, Innospec Limited.

“Every vessel has an optimum engine load where the combustion is almost complete and the SFOC (Specific Fuel Oil Consumption) is at minimum level,” states Ng.

“When an engine is running on a low load condition, the cylinder pressure and temperatures are lower which leads to poorer ignition and incomplete combustion of bunker fuel.

“Though reducing speed offers a better CII rating; this may also lead to energy and combustion efficiency losses that cause preventable damage to vessel machinery.

“Vessels with high engine output will need costly retrofit solutions with high CAPEX in order to permanently work at lower loads.

“From experience, slow steaming usually results in a variety of negative effect on vessel engines.”

Adverse effects of slow steaming on ship engines

Poor Atomisation

Higher volume of fuel trapped at the injector tip (sac) delivering uncalculated fuel to the cylinder and increasing the likelihood of dripping. Increased fouling and carbon deposits all contribute to poor atomisation and subsequent drop in performance.

Poor Combustion Characteristics

At reduced ME load operation, inadequate turbo charger speeds are generated to provide adequate air to the combustion chamber, leading to lower combustion efficiency, unburnt fuel and the formation of harmful emissions.

Reduced Air Flow

Reduces engine efficiency and causes fouling in the air supply/scavenge system. Subsequently this can lead to very high differential and exhaust temperatures which can damage engine components and lead to burned exhaust valve as one example.

Cold Corrosion

Corrosive wear on the cylinder liners caused by acid condensation due to the drop in engine operation temperature caused by slow steaming operation.

Fouling Effect

On Turbocharger (turbine side),

  • On Exhaust Gas Boiler (heat exchanger pipes)
  • On Injector (clogged nozzles),
  • On Piston rings (deposit accumulation - lack of sealing)

‘Smart slow steaming’ with Octamar™ Ultra HF & Octamar™ Complete – fuel treatment systems with Class Verification

Combustion catalysts have a positive impact on the fuel’s combustion profile by providing a faster and more complete combustion of regular fuel at any load condition.

With a significant reduction in uncaptured fuel energy, vessels have seen 2.1-3.9% fuel savings which have contributed to better CII ratings.

“Even till today, issues with slow steaming have remained the same. However, with new regulations and changes in fuel quality over the years, Innospec continues to improve its technology to optimise today’s marine fuel,” informed Ng.

“Octamar™ Ultra HF & Octamar™ Complete allows vessels to slow steam with associated benefits by minimising the adverse effects listed above while improving fuel consumption and emissions.”

The unique treatment package improves energy efficiency of ships by reducing ignition delay, cleaning injectors, and reducing afterburn to mitigate all the issues associated with slow steaming while decreasing combustion properties and early max heat release to maintain energy efficiency.

“ClassNK has also verified several trials conducted over a decade which demonstrated the active fuel consumption (2.1-3.9%) and emissions reduction of Octamar™ technology,” she highlights adding the Octamar ™ solution can be further included in vessels’ SEEMP III.

Malaysia-listed Straits Energy Resources Berhad on Monday (2 October) announced the company’s intention to spin-off its oil bunkering and shipping related services segment for listing on NASDAQ stock exchange in the United States by way of a registered public offering.

In a filing with Bursa Malaysia, the firm said it intends to undertake a reorganisation of some of its subsidiaries involved in the oil bunkering and shipping related services segment, for the purpose of forming a separate listing group or Spin-Off Group suitable for the listing on NASDAQ.

“It is envisaged that these subsidiaries to be comprised in the Spin-off Group will continue to remain as

subsidiaries of Straits upon the completion of the Proposed Listing,” the company said. 

Straits Energy added it will make a detailed announcement in relation to the proposed listing in due course, once the board of directors has finalised and approved the terms and structure of the exercise. 

It said the listing would enable the Spin-Off Group to gain recognition and corporate stature through the listing status of its own on NASDAQ.

The company added the listing would further enhance its corporate reputation and profile which will be conducive in expanding its customer base whilst allowing the Spin-Off Group to expand and establish its global presence. 

The proposed listing would also enable the Spin-Off Group to gain access to the capital market in the United States for capital raising and to provide the Spin-Off Group with financial flexibility for future expansion and growth.

It will also unlock shareholders' value in the oil bunkering and shipping related services and provide transparent valuation benchmark for the same on NASDAQ, it added. 

Manifold Times previously reported marine fuel logistics firm CBL International Limited (CBL International), an ultimate holding company of Banle International Group Ltd (BVI), a 38%-associate company of Straits Energy Resources Bhd announced it would be listed on Nasdaq. 

Later, Manifold Times did an exclusive interview with Banle Group who shared insights on the successful listing of CBL International Limited, its listing vehicle, on the Nasdaq Capital Market
