Johor Port Authority (JPA), being the authority in charge of regulating ports in Johor has collaborated with Universiti Teknologi Malaysia (UTM) to develop an online system named Ship Emission Management System (SEMS) for accounting the shipping emissions and analysing the impact of emission reduction measures in ports (https://sems.lpj.gov.my/). This is one of the green initiatives under JPA Green Port Policy. Under the mandatory requirement of JPA, Johor Port (JP), Port of Tanjung Pelepas (PTP), jetties, terminal and all operation within Pasir Gudang and Tanjung Pelepas Port Water Limit are required to report on ship activities using the SEMS. SEMS comes along with two versions: a web-based SEMS and an IOS SEMS app.
The Development of SEMS commenced on 1 April 2016 and was completed on 30 Jan 2017. Two user training seminars on the web-based SEMS were conducted on 31 May and 21 June 2017, to guide port users (shipping agents) on the system functions and usage. The SEMS has been implemented in Ports of Johor since 1 July 2017 through JPA Port Notice that has been circulated to Port Operators, Ship Owners, Masters of Ships, Forwarding Agents, Freight Forwarders, Associations, Private Jetties and all port users. The SEMS includes the web-based inter-phase and the mobile application to be used by JPA to monitor, calculate and estimate the emissions (CO2, NOx, SOx, PM10 and PM2.5) attributed to each ship operating in the port area. The SEMS provides the following functions:
Ship emissions estimation and calculation (total emissions, total engine emissions and total emissions for each operating mode).
Daily monitoring of ship emissions (through web and iOS).
Data of ship machinery (main engine, auxiliary engine).
Data of type of fuel, amount of fuel usage, sulphur content, time in each operating mode (anchorage, manoeuvring and at berth).
Setting up baseline reduction targets for ship emissions based on the current year total emissions.
Assessment of measures to reduce emissions such as changing fuel type in port area, using shore power supply at berth, ship speed reduction and port call optimisation.
