Ships and Marine Technology — Energy efficiency — Part 1: Energy efficiency of individual

Scope

This standard describes generic measuring and calculation methods to evaluate the energy efficiency of individual maritime components.
A maritime component is defined as having a single function.
Maritime components are grouped according to their functionality to compare the energy efficiency of components which can solve the same task onboard a vessel.

The standard is limited to components for which a “unit output” can be clearly defined and which require energy to function.

The standard only covers energy consuming components.

This standard deals with five types of components:
a. Pressure components
b. Flow components
c. Lighting
d. Heating/Cooling components
e. Mechanical components

The energy efficiency is evaluated using a specified set of global ambient conditions. The energy efficiency is also evaluated using ambient conditions for operation in arctic, tempered or tropical regions.
