How Do You Calculate Ship Fuel Consumption?

The Importance of Calculating Ship Fuel Consumption

Fuel is an expensive commodity, as we all know. Knowing the fuel consumption of vehicles is essential for minimising costs and increasing efficiency. Calculating ship fuel consumption, especially on longer journeys, becomes even more critical. With this data, ships can form better strategies towards achieving maximum fuel efficiency.

At Bell Flow Systems, we supply a wide range of fuel control and measurement products. Fuel consumption solutions for various applications forms a significant part of the range. This includes fuel generators, larger vehicles and in this case; for ships.

Recently we were asked to supply a fuel consumption system on an ex Navy vessel. The Spirit of Samsø was originally known as Y303, a Barsø class vessel belonging to the Danish Navy. Innovative marine engineers, NAVA. are currently re purposing The Spirit of Samsø in to a luxury yacht.   They required a monitoring system installing, in order to measure the fuel consumption of the vessel.

Measuring ship fuel consumption

HDMS Samso Y303 by Ove Jensen

As with a lot of fuel systems, the engine consisted of a supply and return to and from the fuel tank. As such, the system required two flow meters. One to measure the fuel supplying the engine, and one to also measure the fuel flow back to the tank. With all flow metering applications, selecting the correct size meter is crucial. This is to ensure accurate measurements. This is particularly relevant with fuel measurement.

With our expert understanding of fuel flow, we took in to account the engine whilst idle and also when at full capacity. It was also important to ensure that the meter did not reduce the pressure too much so as to starve the engine of fuel. With this is mind, we were able to correctly calculate appropriate sized meters for the job.

The Installation

For this installation, we used Macnaught MX series oval gear meters. Oval gear meters offer a high turndown ratio and a low pressure drop, making them ideal for fuel consumption applications. Their high resolution digital output and high accuracy also lends itself to being a first choice solution. These are paired with a Fluidwell F116 differential flow computer. This meter gives visualisation of the fuel flow rate and total volume of both the flow and return to and from the engine. The computer also handles the flow calculations to clearly show both the current and total fuel consumption.

With this simple solution installed, fuel consumption monitoring is more efficient and ultimately the overall running costs for the vessel decrease.

Products used in this installation were the Macnaught series of fuel and oil meters and Fluidwell F116 flow displays.

High Viscosity Glucose Flow Measurement

Challenging High Viscosity Glucose Flow Measurement in Soda Manufacturing

Bell Flow Systems was approached regarding a rather challenging task of glucose flow measurement. A production line specialist needed a solution for controlling the glucose flow measurement in a newly built processing plant for a large, UK based soft drinks manufacturer.

The glucose was to be pumped through stainless steel dairy pipes and heated to a temperature of 45⁰C. Thus producing a viscosity of 5000 centipoise. Due to the kind of product being manufactured, it was essential to have hygienic connections. The application also specified the installation of digital batch controllers. This was in order to allow operator control of the production process. These dual stage batch controllers offer intelligent over-run correction and two-stage valve closure for accuracy and repeatability.

The system would accurately dispense the exact quantity of glucose for the user-specified mixture each time. This was critical so that the recipe for the soda remained the same and the taste didn’t vary from batch to batch. Due to this high working viscosity, it was determined that a positive displacement flow meter was required.

Glucose Flow Measurement

 

Macnaught oval gear meters for glucose flow measurement

Bell Flow Systems offered one of the Macnaught oval gear type positive displacement meters. This particular range of meters are constructed from food grade stainless steel. Thus making the meter suitable for hygienic application. High viscosity stainless steel rotors allow for measuring viscosities over 100,00 centipoise. Hygienic tri-clamp connections, FDA approval, and locally mounted IP67 rated batch controllers completed the selection.

The oval gear meter principle ensures that there is flexibility of installation. Because there are no straight lengths of pipe needed before or after the meter, they can be installed vertically or horizontally. Additionally, these meters create an exceptionally low pressure drop – which was critical to the application.

Do I need to compensate my water level data for barometric pressure?

One of the first questions we are asked when talking about our water level loggers is “why does my water level data need to be compensated for barometric pressure”

Firstly to explain this we need to look at the two components which vary the pressure being applied to the diaphragm of the pressure sensor, these are the water level and the barometric pressure.

Barometric pressure is the pressure applied by the atmosphere on to the ground around us. The level of barometric pressure is influenced by two main factors, these are Temperature change and Weather systems. Temperature change variation causes the density of air to change, thus varying barometric pressure, change also in humidity can be linked to barometric pressure change. This change in barometric pressure is also used by meteorologists to monitor and predict the changes we see in weather on a daily basis.
The change in barometric pressure is referred to as the diurnal shift. In some areas of the world the diurnal shift can be significant to causes variations of up to 0.30m per day.

What do I need to consider when monitoring water levels?

When conducting the measurement of water level, your product selection is often determined by the measurement period. For example if your measurement period is only for a short period, less than a day, the need to continually measure barometric pressure may not be required. Our Dipperlog Nano systems will always take a single barometric reading and use this for compensation. However if the location / conditions at site or the monitoring is for a long period of time we strongly recommend the use of Barlog sensor to compensate for barometric pressure. Alternatively a vented Dipperlog Nano can be used, as the sensor will provide automatic temperature compensation.

When downloading the data, we always recommend downloading the Barlog information first followed by the Dipperlog Nano pressure data to ensure all recorded readings can be compensated. If no Barlog is used a single value will be used from the initial setup of the sensor.

For more information or to discuss the compensation of water level data please feel free to contact us. sales@bellflowsystems.co.uk

Remote Water Management

Remote Water Monitoring and Management

Remote Water Monitoring and Management in the Hebrides

A customer living in Norway had a remote water metering problem, so they approached Bell Flow Systems to provide a solution.

They owned a second home in the Hebridean Islands, which was left empty for long periods of time and only visited sporadically. The customer wanted to be able to view the properties water usage remotely from their home in Norway, and also set alarms to alert them of any peaks in the flow – which would indicate a potentially burst pipe or other water leak.

This would then enable them to call a local caretaker to come and assess the situation and prevent and further damage to the property or grounds, in addition to preventing a large water utility bill!

RCDL-Badger-Meter

Badger Meter RCDL Nutating Disc Flow Meter

With these criteria in mind, Bell Flow offered a water meter and GSM data logging solution. Considering the relatively high possibility of freezing temperatures and frozen pipes, Bell Flow offered a Badger RCDL Meter with a pulsed output. The RCDL, which is the most popular domestic water meter in the USA, does not suffer frost damage if the water within the chamber freezes, like other types of meter might. The water within the RCDL can freeze and the meter will cease working but when the water thaws again, the meter will continue accurate water monitoring operation once more.

 

Along with this model of pulsed meter, the customer was also offered the Aqualink GSM Datalogger. The pulse output from the water meter would go into the Aqualink – which is fitted with a SIM card. The flow data is then captured by the Aqualink and sent to an on-line water monitoring portal with a secure customer log in.

 

Aqualink II GSM Remote Data Logger

Aqualink II GSM Remote Data Logger

This ensures that the customer can view his water usage anywhere that has internet access. The Aqualink also has the ability to set alarms, enabling the customer to set a warning alert by SMS for excessively high water usage.

This gave the customer peace of mind that he wouldn’t visit the house to find any unexpected water damage, or be surprised by unexpected high water bills.
