Lloyd’s Register: Focus on Energy
Efficiency for Ships

By Jesper Aagesen, Area Consultancy Manager, Scandinavia, Baltic & Western Europe, Lloyd’s Register EMEA

The EEDI requirements will
gradually be tightened during the
coming years and it will mean that
newbuilds in 2025 should emit
less than 30% CO2 than newbuilds
do today.

Due to the above mentioned
reasons it is only natural that many
shipowners are looking at how
they can make their ships more
energy efficient. This is something
that we in the Classification
Society Lloyd’s Register have
experience with and we have
assisted in energy optimisation of
a number of ships.

The shipping industry obtained when working with LLOYD’S REGISTER’S ENERGY

One of the challenges Part of the reason is the ECA of our clients’ requirements.
