AI Technical Summary

Technical Problem

Existing technologies lack unified and universal carbon footprint measurement standards for marine engineering equipment, resulting in poor comparability of measurement results. They are difficult to penetrate to system units and construction processes, and data acquisition is difficult and costly, failing to support low-carbon design and management decisions.

Method used

A multi-level quantitative model is constructed to systematically identify key greenhouse gas emission sources. Carbon footprint is measured by collecting activity level data, including the quantification of equipment system units, construction phase procedures, and materials and energy resources. Emission factors are used for systematic calculation to generate full-process carbon footprint data.

Benefits of technology

It enables the standardization and precise quantification of the carbon footprint of various types of marine engineering equipment, supports carbon emission prediction in the equipment design stage, provides highly comparable carbon footprint data, and supports low-carbon decision-making and management.

Abstract

The invention discloses a carbon footprint metering method for multi-type ocean engineering equipment. The carbon footprint metering method comprises the following steps: defining a full-process metering boundary from raw material acquisition to ocean engineering equipment delivery; the method comprises the following steps: constructing a modular multi-level quantitative model adaptive to different equipment types, and systematically identifying key greenhouse gas emission sources in each period stage; systematically collecting and inputting activity level data generated by target equipment in design, purchase and construction plans based on the multi-level quantitative model; and based on the activity level data, systematized calculation and summarization of greenhouse gas emission are carried out. According to the method, accurate quantification of the equipment delivery carbon footprint obtained from the raw materials can be achieved, carbon emission prediction can be carried out in the equipment design stage, and the problems that in the prior art, due to the fact that maritime work equipment is diversified in type and complex in system, a metering method is poor in universality, and metering results are poor in comparability can be solved.
