NYK Introduces Japan’s 1st Additive for IMO 2020-Compliant Fuel Oil

Japanese shipping company Nippon Yusen Kaisha (NYK) and shipping and marine supplier Nippon Yuka Kogyo, a NYK Group company, have jointly developed a new fuel oil additive for low-sulfur compliant fuel-oil that meets SOx emission requirements.

Yunic 800VLS — patent pending — is Japan’s first additive for very low sulfur fuel oil (VLSFO), NYK said.

The additive is said to improve safety by helping to avoid troubles that may be caused by certain contents of VLSFO, according to the company.

A global sulfur cap will enter into force on January 1, 2020, and one way ships can meet the requirement is by using VLSFO – a fuel oil with a sulfur content below 0.5%. However, a wide variety of VLSFO is expected to be supplied because the manufacturing process differs from conventional heavy fuel oil, which has a sulfur content of up to 3.5%.

NYK and Nippon Yuka Kogyo thus began examining VLSFO at an early stage and have developed an additive that will lessen the likelihood of the VLSFO causing engine problems.

Specifically, Yunic 800VLS disperses asphaltene and paraffin (wax) specific within VLSFOs to suppress sludge formation.

The effect of Yunic 800VLS has been certified by ClassNK.

“The NYK Group seeks to be compliant with the 2020 SOx cap and enrich safe operations by introducing this new fuel-oil additive for VLSFO,” NYK said in a statement.

NYK in biofuel research and testing

Separately, NYK Line and Japan Engine Corporation (J-ENG) revealed they would start the research and development of biofuel using a test engine as one of the solutions for decarbonization.

Considered to be a carbon-neutral fuel, biofuel is a fuel derived from organic substance or biomass.

Biofuel has been attracting attention as an alternative fuel as one of the promising renewable energy toward decarbonization and one of the solutions against the energy crisis due to the depletion of natural resources such as fossil fuel.

In addition, since biofuel emits almost no sulfur oxides (SOx) in combustion, its use as a marine fuel is expected to be expanded.

In collaboration with NYK Line, J-ENG plans to carry out the engine test using the biofuel from GoodFuels, a biofuel supplier based in the Netherlands.
