The maritime industry is undergoing a transformative shift toward sustainability, driven by the International Maritime Organization’s (IMO) regulations. One pivotal regulation is the Ship Energy Efficiency Management Plan (SEEMP) Part III, which mandates vessels to adopt comprehensive strategies for reducing carbon emissions. This blog will delve into SEEMP Part III, its components, practical examples, and key takeaways for shipowners and operators.
The Importance of SEEMP Part III
Shipping accounts for a significant portion of global greenhouse gas emissions. To combat this, the IMO introduced SEEMP Part III as part of its decarbonization strategy under MARPOL Annex VI. Effective from January 1, 2023, SEEMP Part III applies to vessels over 5,000 GT engaged in international voyages. It requires ship-specific plans to achieve and maintain compliance with the Carbon Intensity Indicator (CII), a measure of operational energy efficiency.
Key Features of SEEMP Part III
• A three-year implementation plan for energy efficiency measures.
• Annual targets for CII ratings.
• Procedures for self-evaluation and improvement.
• Corrective Action Plans for underperforming vessels.

What is SEEMP Part III?
SEEMP Part III builds on Parts I and II by focusing on operational energy efficiency. It integrates data collected under SEEMP Part II to establish a CII rating system for ships. The plan must outline specific measures to improve energy performance, with annual evaluations to ensure targets are met.
The vessel Aegean Myth became the first ship globally to have a verified SEEMP Part III. Its plan included using biofuels and optimizing voyage routes to reduce emissions while maintaining operational efficiency.

Core Components of SEEMP Part III
1. CII Calculation and Targets
• Ships must calculate their annual CII and set three-year targets.
• Example: A bulk carrier targeting a 10% reduction in CO2 emissions through speed optimization.
2. Implementation Plan
• Details measures like hull cleaning or adopting energy-saving technologies.
• Example: A container ship implementing waste heat recovery systems to enhance fuel efficiency.
3. Self-Evaluation Procedures
• Operators must monitor progress and adjust strategies as needed.
• Example: Monthly reviews of fuel consumption data on a tanker led to route adjustments for better efficiency.
4. Corrective Action Plans
• Required if a vessel receives a D rating for three consecutive years or an E rating in one year.
• Example: A gas carrier revised its plan by adding wind-assisted propulsion after failing to meet CII targets.
Challenges and Opportunities
SEEMP Part III represents a critical step toward sustainable shipping. Here are the key points to consider:
Proactive Planning: Start early by calculating current CII ratings and setting realistic targets.
Dynamic Implementation: Treat SEEMP Part III as a living document that evolves with operational needs.
Collaboration: Engage stakeholders, including classification societies, for expert guidance.
Continuous Monitoring: Regularly evaluate performance and adjust strategies to stay on track.
By embracing SEEMP Part III, shipowners can not only comply with regulations but also contribute meaningfully to global decarbonization efforts.

The implementation of SEEMP Part III comes with several challenges, such as high costs, operational disruptions, and the need for continuous monitoring. Below are practical solutions to address these challenges effectively:
- High Initial Costs for Technology and Retrofits
Adopting energy-efficient technologies can be expensive, especially for older vessels.
Solutions:
Leverage Incentives and Grants: Seek financial support through green shipping funds or government subsidies aimed at promoting sustainable practices.
Phased Investments: Spread out retrofitting costs by prioritizing the most impactful technologies, such as hull cleaning systems or energy-saving propellers.
Collaborative Financing: Partner with charterers or stakeholders to share costs, especially if the upgrades benefit all parties involved.
2. Operational Disruptions During Implementation
Retrofitting or testing new technologies can interfere with vessel schedules.
Solutions:
Plan Retrofits During Scheduled Dry-Docking: Align upgrades with maintenance periods to minimize downtime.
Trial Technologies on Select Vessels: Test new systems on a few ships before fleet-wide implementation to ensure efficiency without widespread disruption.
Use Simulation Tools: Employ digital twin technology to model and predict the impact of new measures before actual implementation.
3. Continuous Monitoring and Compliance
Maintaining CII ratings requires constant data collection, analysis, and adjustment.
Solutions:
Automated Data Collection Systems: Install advanced monitoring tools that automatically track fuel consumption and emissions in real-time.
Regular Training for Crew: Equip crew members with knowledge on energy-efficient operations and data reporting requirements.
Engage Third-Party Experts: Collaborate with classification societies or consultants for periodic audits and performance reviews.
4. Adapting to Regulatory Changes
The dynamic nature of SEEMP Part III requires frequent updates to plans and procedures.
Solutions:
Dynamic SEEMP Documentation: Treat SEEMP Part III as a living document, updating it annually based on performance data.
Scenario Planning: Prepare for potential changes by simulating various regulatory scenarios and their impacts on operations.
Engage in Industry Forums: Participate in industry discussions to stay ahead of upcoming regulatory trends.
5. Crew Engagement and Awareness
Ensuring crew buy-in for new energy efficiency measures can be challenging.
Solutions:
Interactive Training Programs: Conduct workshops that explain the importance of CII compliance and how crew actions impact ratings.
Gamification of Efficiency Goals: Introduce reward systems for crews achieving specific efficiency milestones.
Feedback Mechanisms: Allow crew members to provide input on operational adjustments, fostering a sense of ownership.
For example, a tanker operator introduced a reward program for crews that achieved monthly fuel-saving goals, improving compliance and morale.
By addressing these challenges proactively, shipowners and operators can ensure smooth compliance with SEEMP Part III while optimizing operational efficiency.
In conclusion, SEEMP Part III represents a critical step toward sustainable shipping. Here are the key points to consider:
Proactive Planning: Start early by calculating current CII ratings and setting realistic targets.
Dynamic Implementation: Treat SEEMP Part III as a living document that evolves with operational needs.
Collaboration: Engage stakeholders, including classification societies, for expert guidance.
Continuous Monitoring: Regularly evaluate performance and adjust strategies to stay on track.
By embracing SEEMP Part III, shipowners can not only comply with regulations but also contribute meaningfully to global decarbonization efforts.
