Solution Overview

Problem

The challenge lies in supplying liquefied natural gas (LNG) to remote and scattered islands where building port infrastructure is not economically viable, and these locations lack the necessary LNG tanker trucks and distribution pipelines, making it difficult to provide a reliable and autonomous LNG supply.

Innovation Solution

A self-propelled barge equipped with LNG tanker trucks, a connection module, loading modules, and distribution modules that can connect to a small LNG carrier for loading and unloading LNG into tanker trucks, allowing for flexible and autonomous LNG distribution to various locations without relying on specific port installations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If large methane or gas carriers are used to transport LNG, then the transport capacity is improved, but the requirement for port infrastructure with large draft and specialized loading terminals increases

Engineering Contradiction:
ImproveLNG transport capacityVSAvoidport infrastructure requirement
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The invention divides the LNG transport system into multiple components: a mother vessel for bulk transport and multiple smaller barges for distribution. Each barge carries multiple tanker trucks, creating a segmented delivery network that can access locations without requiring large draft ports or specialized loading terminals for the entire system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The barges act as intermediaries between the mother vessel and the final delivery point. They receive LNG from the mother vessel and distribute it to tanker trucks, eliminating the need for direct port infrastructure connections at the final destination and enabling service to remote locations.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If port installations are built in each scattered island to supply LNG, then the supply reliability is improved, but the economic viability deteriorates

Engineering Contradiction:
ImproveLNG supply reliabilityVSAvoideconomic viability
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The barges are designed as multi-functional units that can serve multiple islands and locations sequentially. Instead of building dedicated infrastructure at each location, the same barge infrastructure can be deployed to various scattered islands, providing reliable supply without the economic burden of duplicate installations at each site.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system enables self-service delivery where tanker trucks on the barges can autonomously load and distribute LNG to various locations without requiring permanent port infrastructure or specialized loading facilities at each destination. The barges themselves provide the necessary infrastructure mobility.

Inventive Principle:
Principle #25Self-service

3Productivity

If a fixed port-based LNG supply system is used, then the distribution efficiency is improved, but the adaptability to remote and scattered locations deteriorates

Engineering Contradiction:
ImproveLNG distribution efficiencyVSAvoidadaptability to remote locations
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The system transitions from a static port-based infrastructure to a dynamic mobile platform. The barges can move between locations, and the tanker trucks can be distributed to various destinations, allowing the system to adapt its configuration and location based on demand while maintaining efficient distribution through standardized loading procedures.

Inventive Principle:
Principle #15Dynamics
