2. 📝 Content Outline
This content describes the most important new regulations of the International Maritime Organization ($\text{IMO}$) Under the Greenhouse Gas Reduction Strategy ($\text{GHG}$) which has a direct impact on both new ship designs and existing ship operations:
2.1. Context and origin of IMO measures
- target$\text{IMO}$: International shipping must reduce greenhouse gas emissions according to stringent targets.$\text{IMO}$(such as reducing$\text{CO}_2$per unit of freight)
- Mechanism of action: $\text{IMO}$Technical and operational measures are established to achieve this goal, the main ones being:$\text{EEXI}$and$\text{CII}$
2.2. Technical measures: EEXI (Energy Efficiency Existing Ship Index)
- Objective: This is a measure focused on ship design , aiming to improve the energy efficiency of existing ships.
- Definition: $\text{EEXI}$It is a technical index calculated from ship design factors (e.g. engine type, size, design speed) to indicate the discharge level.$\text{CO}_2$per unit of transport per distance
- Design Impact: To pass the criteria$\text{EEXI}$Many ships need to consider technical improvements such as:
- Engine power limitation ($\text{Engine Power Limitation - EPL}$): The easiest and most common way to reduce top speed.
- Installation of Energy Saving Devices (ESDs): such as high-efficiency impellers or devices that improve water flow.
- Shifting to low-carbon fuels
2.3. Operational measures: CII (Carbon Intensity Indicator)
- Objective: It is a measure that focuses on the actual operation of the ship with the goal of reducing the intensity of emissions.$\text{CO}_2$Each year
- Definition: $\text{CII}$It is an index that measures quantity.$\text{CO}_2$The amount of CO2 released by a ship per unit of cargo carried per nautical mile in a year (e.g., grams $\text{CO}_2}$ per ton of cargo per nautical mile).
- Rating and Impact: Ships are rated with a carbon efficiency grade of A, B, C, D, or E by:
- Grade ship$\text{D}$or$\text{E}$In order to improve efficiency, a corrective action plan must be submitted .
- Business Impact: Grade$\text{CII}$It will become a key factor in the decision-making of charterers and financial institutions (Green Financing).
2.4. Integration and impact on industry
- New Ship Design: New ships must be designed for high efficiency from the start (according to the criteria$\text{EEDI}$(already strict)
- Fleet Management: Entrepreneurs Need Technology$\text{Digital Monitoring}$and data analysis for speed control, route planning ($\text{Weather Routing}$), and cleaning the ship's hull ($\text{Hull Fouling}$) to maintain grades$\text{CII}$
- Challenge: These regulations create pressure to accelerate investment in green technologies and the use of new alternative fuels.
