Ship Energy Efficiency Management Plan (SEEMP)

SEEMP Facts • Mandatory for ships >400 GT • No requirement to have SEEMP approved • MARPOL Annex VI will require SEEMP to be onboard • May form part of SMS

SEEMP Aspects • Mini-management system (based on the continuous improvement principle) • Elements missing: mandatory goal setting and performance auditing • SEEMP requirements - industry driven

Monitoring – Operational Energy Efficiency

The Energy Efficiency Operational Indicator (EEOI)

• A tool proposed by the IMO to assist with the

“monitoring” aspect of the SEEMP

• Generally expressed as tonnes CO2 per tonne-nm

• Measure of overall efficiency, easy to calculate based on readily available data

• Challenging to isolate areas of bad performance unless EEOI is broken down into components and filtered

Going a step further…

• Renewable energy sources , Biofuel, Methanol, Nuclear

• LNG as fuel Shipowners see LNG-fuelled engines as a

viable option in the long term (10+ years), particularly for ships on liner trades

Low-sulphur distillate fuel is seen as a short-term solution (within the next five years)

Exhaust gas scrubbing is seen as a medium-term option (five to ten years)

Concluding Remarks

• Ship performance and efficiency is affected by many different factors, detail requires an extra amount of effort. Focussing on a few key performance parameters usually proves efficient

• EEOI can be considered as an ‘overall’ energy efficiency indicator but is ‘crude’ as a detailed measure

• It is difficult to determine the effectiveness of any efficiency measure without first setting a breakdown of the vessel’s energy efficiency into individual aspects

• National or international legislative action, technology development, fuel scarcity and prices all create a very unstable environment

• Investment must be technically and financially substantiated. Beware of substitutes. Evaluation techniques can offer valuable assistance.

• Assume ownership , seek advice
