Achieving regulatory compliance to limit environmental impact

Reducing the marine industry’s carbon footprint is a top priority for local, national and international organizations, which are developing ever more environmental legislation. To meet existing and upcoming regulatory requirements, such as the EEDI, EEXI and CII, ship owners and managers must meet specific limits for energy consumption and carbon emissions.

Bureau Veritas helps ship owners, managers and operators comply with IMO’s Marine Environment Protection regulations and limit their vessels’ environmental footprint. Our experts help clients meet EEDI, EEXI and CII requirements, conducting assessments, performing calculations, verifying technical files and identifying technical and operational improvement methods.

KEY BENEFITS

  • Comply with upcoming and existing IMO regulations for limiting the marine industry’s environmental footprint
  • Improve onboard energy efficiency and minimize fuel consumption for newbuilds and in-service vessels
  • Identify the carbon intensity of ship emissions and implement operational improvement measures to limit impact
  • Benefit from Bureau Veritas’ knowledge of the latest regulations under development by the IMO

The Energy Efficiency Design Index (EEDI)

First entered into force in January 2013, the EEDI requires newbuilds to meet a minimum level of energy efficiency per ton-mile. The EEDI provides a specific target figure for individual ship types, calculated based on the vessel’s technical design parameters. Based on this, ships can develop a Ship Energy Efficiency Management plan (SEEMP) to improve energy efficiency onboard. Bureau Veritas experts are available to help clients develop, verify, maintain and update their SEEMP and achieve EEDI compliance.

The Energy Efficiency Existing Ship Index (EEXI)

Coming into force on January 1, 2023, IMO’s EEXI regulation requires ship owners to track the emissions and energy consumption of in-service vessels over 400 GT. Based on EEDI guidelines, the EEXI is calculated in accordance with MARPOL Annex VI, using standard values for fuel consumption. Bureau Veritas helps clients perform EEXI assessments, gain approval for preliminary technical files, target technical measures for improvement, and be granted a statement of compliance and international energy efficiency certificates.

The Carbon Intensity Indicator (CII)

The CII regulation requires in-service ships of over 5,000 GT to quantify and report on carbon emissions from operations. Calculated as the ratio of total CO2 mass emitted to total transport work per year, the CII enables ship managers to determine their carbon footprint. Owners can then undertake operational improvement measures to minimize their impact and align with IMO decarbonization targets. Bureau Veritas can help managers assess a vessel’s carbon intensity profile, and develop a correction plan and an optimized SEEMP. Along with providing SEEMP verification, we help clients monitor fuel consumption and undergo annual CII reviews.

Calculate EEXI and CII values with VeriSTAR Green

Bureau Veritas’ VeriSTAR Green web platform enables users to easily and efficiently perform calculations for carbon indexes. Ship owners can calculate attained and required EEXI values, measure CII and determine their ship’s corresponding rating, and report on fuel consumption. Through VeriSTAR Green, ship owners can measure their environmental impact, accessing Bureau Veritas experts who can verify emissions and offer technical advisory services. This enables vessel owners to achieve compliance with IMO regulations.
