Stolt Tankers enhances fuel efficiency with Yara Marine’s Fuel Opt

  • Stolt Tankers has confirmed a follow-on order for Yara Marine’s Fuel Opt propulsion optimization technology to be fitted on seven vessels.

Stolt Tankers and Yara Marine Technologies have signed an agreement to equip a further seven tankers with Yara Marine's Fuel Opt propulsion optimization technology. The agreement was signed at SMM in Hamburg, Germany on Wednesday, 7 September 2022. This new order follows the installation and evaluation of Fuel Opt on board the Stolt Breland in early 2022.

Operating the largest fleet of chemical tankers in the world, Stolt Tankers is looking to prioritize voyage efficiency solutions that support emissions reductions. Having successfully trialed Yara Marine’s Fuel Opt system and recorded distinct fuel savings and emissions reductions, the company intends to implement the system across a larger percentage of its fleet.

Jose Gonzalez Celis, Energy and Conservation Manager at Stolt Tankers, said: “This collaboration represents a new step towards our carbon reduction goals. We want to be ahead of the timeline and reach our ambition, and the best way to do so with an extensive fleet like ours is to maximize fuel savings and minimize emissions. Shipping needs practical and cost-effective solutions that demonstrate tangible results, and I am pleased to say that our agreement with Yara Marine Technologies has ensured that we are making real progress towards greater fuel efficiency without compromising operational efficacy. We look forward to working together and collaborating on further solutions for our fleet.”

Fuel Opt maximizes fuel savings through energy efficiency and is compatible with any marine fuel, which supports Stolt Tankers’ goal of having a fuel-flexible fleet. The system allows customers to use all existing fuels while future-proofing for possible new fuels. Extremely versatile, Fuel Opt is also compatible with any propeller or engine, and can be installed on older vessels or newbuilds.

Aleksander Askeland, Chief Sales Officer at Yara Marine Technologies, said: “We are proud to support Stolt Tankers with technology solutions that meet their immediate needs, while also allowing for additional enhancements further down the road to Net Zero. Increased fuel efficiency already plays a key role in cost-effective operations, and will no doubt continue to be a vital part of dealing with the expense of future fuels and upcoming regulations.”

Customers can monitor and adjust Fuel Opt’s ability to directly control speed, fuel consumption, engine power, or a combination thereof based on commands set via an intuitive panel on the bridge. The system adapts propulsive power to changing environmental conditions and erases costly variations in speed and power, leading to increased efficiency, fuel savings, and emissions reductions.

For vessels with a controllable pitch propeller – such as the Stolt Breland – Fuel Opt offers dynamic pitch and RPM optimization that regulates propeller pitch and engine RPM separately. This leads to greater gains in efficiency since the engine and propeller operate at optimal conditions, thereby optimizing energy use.

In addition to Stolt Tankers, Yara Marine has worked with Neste, Ardmore, Teekay, Stenersen, Donsötank, Ektank, and more to provide fuel savings via Fuel Opt across both short sea and deep sea operations.
