Four techs to optimise fuel consumption

Four techs to optimise fuel consumption

As 2020 gets underway, shipping companies are looking to keep their voyages as fuel efficient and cost efficient as possible to remain at a competitive advantage. In this week’s spotlight, VPO Global highlights four technologies that are helping shipping companies to optimise fuel consumption.


German technology company SCHOTTEL offers the Rudder EcoPeller, a marine propulsion system that delivers high propulsion efficiency with excellent course-keeping stability to ensure low fuel consumption, low operating costs and low emissions.

EcoPeller has been developed primarily for open sea and coastal operating conditions and combines SCHOTTEL’s current technology with the latest, hydrodynamic insights from CFD simulations and model tests.

The SRE is based on the SCHOTTEL Combi Drive design principle: The electric motor is vertically integrated into the support tube of the EcoPeller. This design saves space and eliminates the upper of the two angle gears as well as any necessary shaft lines. According to SCHOTTEL, the EcoPeller offers unbeatable comfort thanks to extremely low vibration and low noise levels.

Additionally, the integrated High-Torque-Gear (HTG) technology provides enhanced durability and uptime of the thruster, while the LEACON sealing system guarantees highest oil-to-water-interface protection.

The EcoPeller is currently leading the Norwegian ferry market as it has been selected to be installed in eight newly-built ferries of two of the biggest Norwegian ferry lines.

FuelSave FS Marine+

FS Marine+ is a patented marine hydrogen synthgas generator with proven fuel savings of at least 10 per cent. Developed by German firm FUELSAVE, the technology consists of a controlled hydrogen syngas generator and injector that combines a proprietary gas injection with other efficiency enhancement processes like a specific water methanol injection to increase combustion efficiency, leading to a cleaner and cooler combustion, thereby reducing fuel consumption and emissions.

Fuel consumption can be reduced by up to 25 per cent equating to net savings of 16 per cent and a significant reduction in CO2 and NOx emissions and particulate matter (PM).

FS MARINE+ solution has been field-tested on high seas and has been certified and approved by DNV GL as the world’s first onboard hydrogen generator and injection solution with gas & liquid injection mechanisms and processes.

FS MARINE+ is available in a container version for simple “plug & play” installation.

Marc Sima, president and co-founder of Germany’s FuelSave, is confident that shipowners choosing sulphur fuel oil (LSFO) for 2020 compliance over scrubbers will benefit even more from fuel optimisation as these fuels are more costly than those used alongside scrubbers. These costs will continue to rise as well, reducing the amortisation period, and providing a better return on the investment (ROI) for efficiency enhancement technologies. “The more expensive fuels become the greater the fuel saving, and consequently greater reductions in OPEX,” he said.

METIS Cybertechnology Fuel oil monitoring Analysis Agent

METIS Cybertechnology has developed a fuel analyser that quantifies the amount of fuel used and generates a cost calculation based on this. The solution helps shipping companies to estimate the cost of a future voyage, thereby helping them to plan the most fuel efficient route. According to METIS, this can lead to effective and efficient agreements between the charterer and the maritime company, help with budget planning, and indicate possible vessel faulting/fouling.

The analysis agent works by collecting and processing in real time information from flow metres, cargo profile parameters, the hull and propeller operation, vessel speed, and sea and weather conditions.

FUELTRAX Energy Fuel Management System

FUELTRAX’s energy fuel management system measures fuel directly and sends standardised data in real-time every 15 minutes, providing clarity on how fuel is being consumed. The technology uses Coriolis mass flowmeters to measure fuel and ensure regulatory compliance.

According to FUELTRAX, the technology is easy to install and compatible with any vessel, engine and fuel type.

Accuracy is guaranteed and tampering or theft is instantly detectable, enabling complete monitoring of fuel to optimise consumption.

The addition of FUELTRAX Vision can also be deployed to increase security. Cameras are placed to provide 24-7 coverage, providing insight into vessel activity from anywhere in the world. All video surveillance collected by FUELTRAX is coupled with a shipping company’s existing fuel monitoring data and tracking information, to provide greater transparency of vessel operations.

In January this year, FUELTRAX was certified by Verifavia against the European Union’s (EU) Monitoring Reporting and Verification (MRV) regulation requirements and IMO Data Collection System (DCS). Nicolas Duchêne, chief operating officer & VP technical, Verifavia Shipping, said: “Shipowners and operators need confidence in the system they choose to review their fuel data and FUELTRAX is a system which optimises fleet-wide reporting while minimising resource and costs. Verifavia’s specialist team uses its extensive experience to provide an independent and efficient certification service. We know that certification provides our customers with third-party verified assurance that the systems meet the highest standards in emissions monitoring and reporting.”
