标准范围
本文件规定了通用测量和计算方法，用于评估安装在船舶、内河航行船舶和海上结构上的功能系统中连接的多个组件的能效。海事功能系统由集成多种功能的多个组件组成，共同努力实现一个总体目标。本文件的目的是展示各种功能系统的能效如何与船上具有相同功能的其他装置相对应，从而确保高效设计得到回报。海事系统根据其功能进行分组，以比较可以在船上完成相同任务的功能系统的能源效率。本文件仅适用于可以明确定义单位输出且需要能量才能运行的功能系统。本文件适用于耗能功能系统。它不提供生命周期评估（LCA）。注:当考虑消耗物质的系统时，生命周期评价可能是有用的，如果不使用这些物质，这些系统将无法满足功能要求。一个例子是使用活性物质的压载水管理系统（BWMS）（本文件不考虑这些类型）。本文件适用于以下五类功能系统:a)压力和流量；b)照明；c)加热和冷却；d)机械；(e)推进。
This document specifies generic measuring and calculation methods to evaluate the energy efficiency of multiple components connected in a functional system installed on board ships, vessels for inland navigation and offshore structures.
A maritime functional system consists of multiple components integrating multiple functions, working together to achieve an overall goal.
The purpose of this document is to show how the energy efficiency of various functional systems correspond to the other installations on board of same functionality, thus ensuring that efficient design is rewarded.
Maritime systems are grouped according to their functionality, to compare the energy efficiency of functional systems which can fulfil the same task on board a ship.
This document is applicable to only the functional systems for which a unit output can be clearly defined, and which require energy to function.
This document is applicable to energy consuming functional systems. It does not provide a life cycle assessment (LCA).
NOTE An LCA can prove useful when considering systems which consume substances, and which would not meet the functional requirements without the use of these substances. An example is a ballast water management system (BWMS) using active substances (these types are not considered in this document).
This document is applicable to the following five types of functional systems:
a) pressure and flow;
b) lighting;
c) heating and cooling;
d) mechanical;
e) propulsion.
