Normec Verifavia’s Onboard Management Manual (OMM) for Existing Ship Overridable Power Limiters (EPL/ShaPoLi) operates within the intricate regulatory framework governing greenhouse gas emissions from international shipping. Here, we illuminate key aspects to facilitate informed decision-making: 

EEXI (Energy Efficiency Existing Ship Index):
  1. Established by the International Maritime Organization (IMO) via Resolution MEPC.335(76), this index mandates specific energy efficiency levels for all ships over 400 GT by designated deadlines (typically first renewal survey post-1 January 2023). 
  2. Compliance hinges on a formula incorporating ship type, size, and technical characteristics as assessed during surveys. 
  3. Detailed regulations concerning EPL/ShaPoLi  implementation, operation, and record-keeping are outlined within the resolution and associated guidelines. 
Understanding EPL/ShaPoLi: 
  1. EPL/ShaPoLi serve as a technical instrument for achieving EEXI compliance by restricting a ship’s maximum engine power output. 
  2. These systems are designed to permit override in emergency situations, ensuring full power availability. 
  3. Their implementation necessitates meticulous adherence to specific regulations (refer to IMO Resolution MEPC.335(76) for comprehensive details).

FAQ

Find answers to the most commonly asked questions

What are the core components of an effective OMM for EPL/ShaPoLi?

An effective OMM for EPL/ShaPoLi  should encompass: 

  1. Detailed procedures: Covering EPL/ShaPoLi activation, deactivation, response time, record-keeping, and reporting, aligned with relevant regulations like IMO MEPC.335(76). 
  2. Standardized forms: Facilitating consistent and accurate documentation of EPL/ShaPoLi usage, power limitations, and overrides. 
  3. Comprehensive checklists: Ensuring adherence to all procedures and capturing critical data points for regulatory compliance. 

How does the OMM ensure accurate and transparent record-keeping of EPL/ShaPoLi usage?

The OMM should: 

  1. Utilize standardized forms for recording EPL/ShaPoLi operating data, including timestamps, power limitations, and override events. 
  2. Implement a clear record-keeping system for easy access, retrieval, and verification by crew and regulatory authorities. 
  3. Establish protocols for data security and integrity to ensure accurate reporting. 

How can the OMM be adapted to different EPL/ShaPoLi system types and vessel profiles?

An effective OMM should be adaptable to various EPL/ShaPoLi systems and vessel configurations through: 

  1. Modular design: Allowing for customization of procedures and forms specific to the installed EPL/ShaPoLi system. 
  2. Risk-based approach: Tailoring procedures and training based on the specific risks associated with the vessel type and operational profile. 
  3. Regular review and update: Ensuring the OMM remains relevant and effective through continuous evaluation and adaptation to changing regulations or operational needs.
