In today’s evolving maritime landscape, adhering to EEXI regulations is non-negotiable. Many vessels are now equipped with power limitation solutions, such as EPL (Engine Power Limitation) or ShaPoLi (Shaft Power Limitation). However, to ensure compliance and operational efficiency, it is equally important to keep the documentation accurate and up-to-date alongside implementing these technical measures.
🛠️ Why Proper Documentation Matters
Having clear and compliant records is not only essential for meeting statutory requirements but also crucial for ensuring the safety of your operations. Correctly documented measures ensure that your crew and pilots have the precise information needed to navigate safely and efficiently.
🔍 Key Insights on Power Limitation Solutions
EPL & ShaPoLi: Overridable power limitations allow temporary bypassing under specific circumstances. Whether it’s a mechanical fuel rack blockage or software-controlled limits, proper documentation in the Onboard Monitoring Manual (OMM) is mandatory and must be approved by the EEXI verifier.
- Permanent Power Limitation: Unlike overridable solutions, these modifications cannot be overridden by the crew. They ensure consistent operation within the designed range, often combined with propeller retrofits or turbocharger adjustments. Accurate descriptions must accompany the EEXI Technical File, replacing outdated OMMs.
- Engine Derating: Reducing engine power through technical modifications like cylinder deactivation or bore adjustments requires updates to the NOx Technical File and IAPP certificates.
📋 Manoeuvring Information Updates
Power limitations impact vessel manoeuvrability, necessitating updated wheelhouse posters and manoeuvring test trials. Providing accurate data to pilots ensures smooth operations in real-world conditions.
💡 Practical Recommendations
- Always keep OMMs or permanent limitation reports on board.
- Update manoeuvring information to reflect new propulsion characteristics.
- After a propeller retrofit, ensure previous documentation aligning with old power reserves is removed.
