MTCC-Asia Pilot Projects

1. Uptake of port energy efficient technologies and operations (Ship Trim Optimization)

For a target ship with constant speed, the rapidity of the ship will change with the trim difference when the speed of the main engine is fixed. This trim which minimizes the EEOI value of a ship at a given displacement and engine speed, is called the optimum trim of the ship. Ship trim optimization simply advocates selecting the trim condition for minimum resistance. Less resistance implies fewer emissions and more economical operation by fuel savings.

Ship trim optimization can be achieved by operating cargo and ballast water on board instead of installing new equipment or changing ship’s hull structure, therefore optimizing the trim of a ship is a reasonable and advantageous way to achieve lasting reductions in fuel consumption. As of the date of submitting this report, 68,517 of sets of data for determining the ship optimum trim in total has been successfully collected from 15 demonstration ships by MTCC-Asia after installing the system developed on board.

 

2. Fuel consumption automated data collection and reporting

As MTCC-Asia determines one of the main purposes of implementing this pilot project is to validate the availability and reliability of the collection method on ship fuel oil consumption data instead of emphasizing the quantity of ship fuel oil consumption data collection and ship number that the data is collected from. Currently, total 68,517 of sets of ship fuel consumption data has been successfully collected from 15 demonstration ships (5 container ships, 5 bulk carriers and 5 oil tankers, respectively) by MTCC-Asia. The data quality indicates that the method used by MTCC-Asia, i.e. collect data by seafarers through bunker fuel oil tank monitoring on board, transmit data through BeiDou Navigation Satellite System and produce aggregated data through electronic means is a reliable method that can be used in ship fuel consumption data collection and reporting in accordance with the IMO requirements.

For ships which the flowmeters and their supportive electronic system are installed and working in normal conditions on board, the data collected on these ships board can be collected more frequently (every 15 minutes) and more accurately in an automatic manner. However, for ships which the flowmeters and their supportive electronic system are not installed on board, the data collected on these ships board can only be collected by seafarers after they use bunker fuel oil tank monitoring on board in daily interval and transmitted from ship to shore via the system developed by MTCC-Asia.
