Ways on reducing fuel consumption is a major concern that’s been stressing out constantly in the shipping or maritime industry.
Essentially, decision making in shipping fleets would always involve cost savings, most especially when it comes to reducing fuel consumption. Behind that increased fuel utilization are factors affecting not only the ship’s fuel usage but also its operation in general. Commonly, a vessel’s power versus its speed curve is inclined upon the delivery sea trials.
The “power” is actually a more balanced parameter in contrast to fuel consumption and thus, it’s quite easier to be measured. On the other hand, the equivalent ship’s speed is actually determined to be the most compelling parameter measuring both power and fuel consumption.
Aside from the elevated resistance, speed, and fuel usage, there are more elements to consider, such as:
- Heightened draft and dislocation
- Weather conditions become worse
- Worsening of the hull and propeller roughness
Mostly, the shipowners and the overall management of every ship explore alternatives to reduce fuel consumption. Nowadays, the advancement of technology is incorporated to help the marine field in applying options wisely to fully realize the reduction of fuel expenditures.
The following are examples of fuel efficiency measures, integrating technology progress.
Low Loss Hybrid Energy System is an ingenious technology that uses a variety of power sources. It combines with energy storage devices to perform the prime movers nearest to their most ideal performance. Simply, it features its ability to minimize transient engine loads, which cause heightened fuel usage and added emissions. The Low Loss Hybrid Energy System is associated with inverter control devices and interfaces with typical power management structure.
In addition, through elevating the redundancy of power, the LLH System permits the engine to operate near its optimum layout point where having the least emissions and highest efficiency. Decreased maintenance and boost system performance by rapid feedback from the energy storage system is also the benefits catered. the general hybrid control scheme is the key factor in the entire stability and control of the vessel’s electrical structure and flow of energy.
Fuel Oil Emulsion Technology is also one of the most innovative creations for significantly lessening the consumption of fuel. This kind of technology burns more effectively than unconverted fuel and thus, consumes less fuel. As well, lower emissions and engines operate cooler. Hence, these would absolutely require much lesser maintenance. As a result, can promote significant cost savings.
Air Lubrication, Onboard DC Grid System, Fuel Saving Propeller Attachment & Nose Job
The Air Lubrication System, also known as the “Bubble Technology” is a measure to lower the resistance between the vessel’s hull and the seawater using air bubble. This method works by supplying air to the vessel’s underside to help form a layer of tiny bubbles. Definitely, this would help in diminishing the friction between the seawater and the hull.
The Onboard DC Grid scheme aids ships in reducing fuel consumption by cutting the noise and trimming their environmental influence. This measure that allows engines to work at variable speeds for top fuel efficiency at every load has been determined to minimize specific fuel oil utilization up to twenty-seven percent. It has been shown as well that 30% of the noise of the engine room has reduced. As a result, contributes to enhanced working conditions on-board the ship.
The Fuel Saving Propeller Attachment is also an effective energy-saving tool. It is attached to the ship’s propeller hub, generating countering swirls that offset swirls created by the propeller. Therefore, this develops propulsion efficiency.
The Nose Job or Modifying Ship’s Bulbous Bow is a sufficient method of reducing fuel consumption. The inventors of this technology created bulbous bow fuel efficiency adjustments to a container ship. Basically, this leads to a verified twenty-three percent reduction in Carbon Dioxide emission for more than half a year.
The Netwave Seawise Technology
Netwave Seawise BV – the VDR expert also introduces its cost-efficiency strategy by creating the Seawise Big Data Technology. It is a generic resolution that directly collects, normalizes, reports, and validates all sorts of important data and details onboard the ship. At the same time, developing for an immediate or future determination and performance optimization via the cloud.
The Seawise Technology either utilizes the Netwave’s VDR or the Netwave dedicated Seawise gateway as a form of data gathering device, sending information to the cloud. There, the data is harmonized and analyzed. The result of which can be readily available for further processing and analysis.
The Netwave Seawise Technology filters, stores and forwards data into the cloud through the vessel’s current data communications structure. Hence, filtering, encrypting, and compressing the integrated data communications cost is slight.
