The Energy Efficiency Design
Index (EEDI) of a ship is an estimate of CO2 emissions per unit of traffic
volume (freight volume) during the design stage of the ship. EEDI is a design
index that considers the main factors and possible improvement methods of CO2
emissions generated by the ship inworking conditions, and encourages ship
designers, shipyards, and equipment manufacturers to take measures to improve the
energy efficiency of the ship and promote technological progress and innovation.
It has nothing to do with the operation situation of the ship. The use of the
energy efficiency design index is to consider increasing the traffic volume of
the ship and taking various measures to reduce CO2 emissions during the design
stage of the ship.
China Classification Society
(CCS) officially released the Rules for Green Ships on July
10, 2012, which are the world’s first rules for green ships for energy
conservation, environmental protection and working environment. In 2020, CCS upgraded
the original Rules, combined with the new connotation of green and ecological
development in the new era, and formulated the Rules for Green Eco-Ships (2020) which
incorporate new concepts of ecological development, promoting the upgrading of
new green technical standards, and guiding sustainable, high-quality
development of shipping.
According to the requirements of the Rules for Green Ships
and relevant guidelines, CCS provides the following services:
● Green ship type approval/evaluation services:
CCS provides green ship type approval/evaluation services to assist domestic
shipyards and designers to develop ship types in accordance with the
requirements of the Rules for Green Ships, or to
upgrade the existing design of domestic shipyards and designers to improve the
competitiveness of the industrial community.
● Green ship classification service: All ships
that meet the requirements of the CCS rules for classification and have good
environmental protection and energy efficiency performance are granted the
green ship I/II/III class notation as a whole, or a separate class notation is
granted to one of these items. This will help shipbuilders to obtain more orders,
shipowners to meet the relevant requirements of maritime regulations and port
states, and charterers to better understand the environmental protection
performance of ships and will also guide the industry to develop new green and environmentally-friendly
ship types and adopt efficient green new technologies.
