At MISC, we recognised the direct impact of  energy consumption on climate change. The energy consumption from shipping operations largely came from the usage of marine fuel as it corresponds with the distance travelled by the vessels. The IMO has also developed an Energy Efficiency Design Index (EEDI) in 2011 to ensure the newly-built vessels are meeting the energy efficiency standards. A more stringent standard will be developed from time to time, currently at Phase 3 which is applicable to new vessels built after 2025.

Along with the advancement in maritime technology over the years, many newbuilds have been fitted with environmentally friendly features. The older vessels also have been retrofitted in order to meet the IMO EEDI standard.

2018 Highlights

19 vessels
10 reduction
ISO 50001


With the recently established carbon reduction targets, MISC has intensified its efforts to reduce our carbon footprint and improve operational efficiency.

Over 2018, we implemented DNVGL’s Navigator and Eco Insight monitoring and reporting tool fleetwide. This enables better informed decisions on vessel energy efficiency, with system generated alerts for potential fuel saving. We also continued our implementation of ISO 50001 Energy Management System. The certification supports better integration of processes and drives the commitment for MISC to continually improve energy management as well as our carbon performance. Moving forward, the plan is to obtain certification for our LNG and product vessels.

In addition, energy saving second generation Propeller Boss Cap Fins (PBCF) were installed on an additional three LNG vessels in 2018. PBCF are an energy saving device that enhances propeller efficiency, thus requiring less power to propel the vessel forward at a certain speed Refinements in fin shape and height mean enhanced propeller thrust and reduced torque, which should lead to fuel savings of 4-5 percent, compared to 2 percent with the first generation PBCF. To date, a total of 19 vessels in our fleet have been installed with PBCF.

Hull cleaning and propeller polishing is carried out across the fleet based on performance trend analysis and continuous monitoring of each vessel’s performance in order to avoid excessive fuel consumption.

The energy efficiency performance of our vessels during discharging and loading operations at ports is also monitored using the Energy Efficiency Discharging Index (EnDI) and Energy Efficiency Loading Index (EnLI). Opportunities for fuel saving are highlighted timely to our operations and commercial team for performance enhancement and we have registered a gradual improvement in EnDI and EnLI indicators across the fleet. An average of 10-15 percent reduction in EnDi and EnLi was observed in 2018.
