Main Engine Fuel Oil Consumption Monitoring

Engine Fuel Oil Consumption

Today, more than ever industries including shipping industry are expected to decrease their CO2 emissions in order to alleviate global warming.

The European Commission supports the idea of an internationally established global solution to reduce GHG emissions from vessels. This is why in 2012 the European Commission submitted a proposal on a monitoring, reporting and verification system for vessel emissions based on fuel consumption that could lead to additional alleviation strategies.

The challenge

Shipping companies make strategic decisions to reduce everyday operational cost. Hence, fuel oil consumption becomes top priority to achieve that point.

Many shipping companies face the problem of disagreement between ship management and onboard crew to determine fuel oil consumption. This dispute arises when determining fuel consumption because factors that influence the ship engine performance depend on sailing conditions. It is quite often reported that the real quantity of the fuel consumed during the trip is found to be less than the quantity missing from the fuel boiler and this cannot be explained under normal circumstances.

In an era where environment matters and fuel consumption is a crucial parameter in a ship’s operation, the ability to make early accurate predictions is essentially needed.

Facing the problem of disagreement as mentioned above, one of the largest shipping companies in Greece discussed with LAROS team and sought a solution for one of their containerships.

Facing the problem of disagreement as mentioned above, one of the largest shipping companies in Greece discussed with LAROS team and sought a solution for one of their containerships.

Laros solution

A solution was built using LAROS wireless sensor network platform to monitor basic parameters regarding the operation of the Main Engine and especially the Fuel Oil Consumption. This is a useful application of LAROS for the maritime companies that need to monitor the fuel consumption of every vessel during the trip and correlate with the rest parameters to conclude.

The wireless sensor network consists of sensors that are installed at various engine stages. The necessary parameters to monitor are the Main Engine Fuel Oil Flow, Temperature and the Fuel Oil Flow that returns to the boiler. These parameters combined calculate the Specific Fuel Oil Consumption and the total tons of fuel consumed during the trip. This is calculated to make sure that all missing fuel has been really consumed.

The sensor data are collected by wireless nodes that form a wireless network. The nodes send the data through a gateway to an onboard server. Then, data are sent via satellite link at the headquarters, where land-based engineers can extract useful information about the vessel’s engine operational status and provide maintenance instructions to the onboard engineers.

LAROS software is installed on the company’s computers in order to create the data analysis and produce reports and early warnings. Reports are fully customized depending on what engineers request to get informed about.

Benefits

LAROS system provides real time feedback on fuel use. Since LAROS was installed the ship operators have all the data they need and train their crew to embrace approaches on sailing that are fuel-efficient and to optimize their maintenance and cleaning plans. Due to this fact, ship savings on fuel consumption reach about 3-5% every day.

Moving Forward

LAROS system is easily expandable in order to host new sensors that can monitor several parameters at the vessel’s engine room that are significant for the efficient vessel operation. After 3 months of operating LAROS system, the shipping company requested its installation in 15 additional containerships of its fleet.
