Mobile Emissions Control System for Ship Exhaust Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current alternatives for reducing emissions from auxiliary diesel engines on ships at berth are either cumbersome, expensive, or unavailable, making it difficult for vessels to comply with regulations like the CARB at-berth regulation, which can result in ships being unable to dock at major ports and hinder business expansion.
Innovation Solution
A movable emissions reduction system comprising an emissions capturing system and an emissions control system, where the capturing system uses a telescoping or articulating duct connected to a crane or boom to capture diesel engine exhaust and direct it to a mobile emissions control system, allowing for regulatory-compliant air emission even without shore power connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If shore power connections are used to reduce emissions, then emission reductions are achieved, but the system becomes cumbersome and expensive
Solution Approach 1:
The invention extracts the emissions treatment function from the ship's auxiliary engine system and implements it as a separate, mobile emissions control system that can be deployed independently. This allows emissions reduction without requiring complex shore power infrastructure modifications or permanent installations on the vessel.
Solution Approach 2:
The mobile emissions control system acts as an intermediary between the ship's exhaust and the environment, capturing and treating emissions without requiring direct connection to shore power. The system includes a mobile platform with exhaust capture equipment and emissions treatment components that can be positioned near the ship and operated independently.
2Object-generated harmful factors
If alternative control techniques are used to reduce emissions, then emission reductions are achieved, but the techniques are unavailable or not economical
Solution Approach 1:
The mobile emissions control system is designed to be self-contained and self-sufficient, with its own power source and emissions treatment capabilities. The system can operate independently without requiring connection to external shore power infrastructure, making it economically viable for vessels that cannot or choose not to use shore power.
Solution Approach 2:
The system employs a mobile platform that can be dynamically positioned and deployed as needed. The mobile nature of the system allows it to adapt to different ship configurations and port conditions, providing a flexible and cost-effective solution compared to fixed shore power infrastructure.
3Ease of operation
If the emissions control system is made mobile for easier deployment, then ease of operation is improved, but system complexity increases
Solution Approach 1:
The mobile platform serves multiple functions: it provides mobility for easy deployment, houses the emissions control system, and can be positioned to optimize exhaust capture. This multi-functionality reduces the need for separate specialized equipment, thereby managing system complexity while maintaining operational ease.

AI summary
A mobile emissions control system having an emission capturing system and emission control system is provided for diesel engines operated on ocean-going ships at-berth. The emissions control system may be mounted on a towable chassis or mounted on a barge, allowing it to be placed alongside ocean-going ships at-berth. A crane or boom transfers a duct of the emissions capturing system extending from the emissions control system to the ship to capture exhaust from its engine. Alternatively, the system may be mounted on an automated guided vehicle (AGV) equipped with a tower and a crane. The crane mounted on the AGV then lifts the duct forming part of the emissions capture system to the ship's exhaust system to capture exhaust from the ship's diesel engine and transfers it to the emissions control system, which cleans the exhaust and then passes clean air into the atmosphere through an exhaust outlet.
