The Impact of New IMO Regulations on Offshore Vessel Chartering
Mar 31, 2025
Introduction: The IMO’s Push for a Greener Maritime Industry
The International Maritime Organization (IMO) has set ambitious new environmental regulations aimed at significantly reducing the maritime industry’s carbon footprint. These regulations, which focus on lowering greenhouse gas (GHG) emissions and improving energy efficiency, have major implications for offshore vessel chartering.
With the Energy Efficiency Existing Ship Index (EEXI) and Carbon Intensity Indicator (CII) now in effect, vessel owners, charterers, and operators must adapt to stricter compliance requirements, navigate higher operational costs, and rethink fleet strategies to stay competitive.
This article explores the key IMO regulations affecting offshore vessel chartering, their financial and operational impact, and the best practices for ensuring compliance while maintaining efficiency.
1. What Are the New IMO Regulations?
In July 2023, the IMO updated its GHG reduction strategy, setting net-zero emissions targets by 2050, with intermediate goals of:
✔ A 20% reduction in emissions by 2030
✔ A 70% reduction by 2040 (compared to 2008 levels)
The key regulations affecting offshore vessel chartering include:
📌 Energy Efficiency Existing Ship Index (EEXI)
The EEXI measures the energy efficiency of existing vessels based on engine power, fuel consumption, and operational efficiency. Ships that fail to meet the required standards must undergo technical modifications, such as:
✔ Engine power limitations (EPL) to reduce emissions
✔ Retrofits like hull coatings & air lubrication systems to improve efficiency
📌 Carbon Intensity Indicator (CII)
The CII evaluates a vessel’s annual carbon emissions relative to cargo capacity and nautical miles traveled, assigning a rating from A to E:
✔ Vessels rated D or E for three consecutive years must submit a corrective action plan
✔ Poor ratings could impact charter marketability, as charterers may prefer higher-rated vessels
💡 Why It Matters: Owners and operators must continuously improve efficiency to maintain favorable CII scores, or risk penalties and reduced chartering opportunities.
2. How Do These Regulations Impact Offshore Vessel Chartering?
🚢 For Vessel Owners & Operators
✔ Increased Compliance Costs – Retrofitting older vessels with fuel-efficient technology (e.g., LNG engines, energy-saving devices) requires significant capital investment.
✔ Operational Adjustments – Owners may need to implement slow steaming strategies or optimize voyage planning to maintain better CII ratings.
✔ Regulatory Pressure – Vessels with low efficiency ratings may face higher insurance premiums and limited chartering opportunities.
📅 For Charterers
✔ Vessel Availability Challenges – Some older vessels may exit the market due to high compliance costs, leading to temporary fleet shortages.
✔ Higher Charter Rates – Owners investing in IMO-compliant retrofits may increase day rates to offset costs.
✔ Contractual Adjustments – New charter agreements must specify who is responsible for compliance-related modifications, fuel expenses, and emissions reporting.
💡 Example: An offshore wind farm developer looking to charter a Platform Supply Vessel (PSV) may now prioritize vessels with high CII ratings to meet their own sustainability targets and ESG commitments.
3. Best Practices for Compliance & Risk Mitigation
To successfully navigate the evolving regulatory landscape, offshore vessel owners and charterers should focus on:
⚡ Investing in Energy Efficiency Upgrades
✔ Hull modifications & friction-reducing coatings
✔ AI-powered fuel monitoring systems to optimize consumption
✔ Hybrid propulsion systems (LNG-electric, battery-assisted solutions)
📊 Leveraging Data-Driven Decision Making
✔ Real-time emissions tracking software for monitoring vessel efficiency
✔ Predictive analytics tools to optimize voyage planning and fuel usage
✔ Digital platforms to streamline regulatory reporting & compliance
🤝 Strengthening Charter Agreements
✔ Clearly defining CII responsibility in time-charter contracts
✔ Establishing cost-sharing mechanisms for emissions-reduction modifications
✔ Negotiating flexible charter periods to accommodate compliance adjustments
💡 Example: A vessel owner using real-time fleet analytics to adjust routes, optimize speeds, and reduce fuel consumption can improve CII ratings without making costly physical modifications.
4. The Future of Offshore Vessel Chartering Under IMO Regulations
As IMO regulations tighten, the offshore chartering market will continue evolving:
✔ Eco-friendly vessels will become more valuable, leading to increased demand for LNG-powered and hybrid vessels.
✔ Digitalization will play a bigger role, with AI-driven platforms helping owners and charterers track compliance, optimize operations, and reduce emissions.
✔ Vessel financing models may shift, with more owners seeking green financing options to fund retrofits.
Companies that proactively embrace compliance strategies will gain a competitive advantage by securing better charter contracts, maintaining lower operating costs, and aligning with global sustainability goals.
