Energy Efficiency of Dredging Activities
The CEDA WG Energy Efficiency is well on track with its paper titled: ‘Energy Efficiency of Dredging Activities’.
The paper will cover the subject energy efficiency of dredging activities from a project – as well as an equipment related perspective.
For a project it is noted that the greatest opportunities regarding energy efficiency are in decisions made in the early phases of the project life-cycle. Therewith challenge is to mobilise relevant expertise regarding energy efficiency opportunities from the very first design phases.
Life Cycle Analysis (LCA) covering the construction-, maintenance - & end of life lifetime phases of dredging equipment clearly shows: It is (fossil) fuel consumption during the operational lifetime phase, together with the emissions related to this fuel consumption, that greatly dominates the environmental impact of dredging equipment over its entire life cycle. Therewith the relevance of energy efficiency of dredging equipment is substantiated within an ‘equipment perspective’.
Another example of an actual topic covered in the paper will be: ‘legislation’. Given the Paris Agreement national and international legislation is evolving towards a complex variety in regulations. For illustration: most dredging equipment has to comply with international regulations as set by the International Marine Organization (IMO) and the national regulations as applicable for dredging projects. The resulting complexity here often stems from a difference in level of ambition regarding wanted reductions of fuel and related emissions.
Please note that a presentation of the WG Energy Efficiency is part of session 1 of the upcoming CEDA Dredging Days 2019 2 (7-8 November, at Ahoy Rotterdam).
Naturally this presentation is a welcome opportunity to get updated on the subject ‘Energy Efficiency of Dredging Activities’ as well as to provide your feedback regarding the WG’s findings.
