Container Ship Deck Loading Space for Shallow Water LNG Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for supplying liquefied natural gas (LNG) to remote areas lacking infrastructure are inefficient due to the need for separate storage tanks and complex, costly transportation processes, and existing ships cannot navigate shallow waters or operate without dedicated port facilities.
Innovation Solution
A container transportation ship with a cargo space and loading/unloading space on its deck, equipped with a crane for moving containers and a barge-type hull, allowing for the direct loading and unloading of LNG tank containers without the need for separate handling facilities, and capable of sailing in shallow waters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a general container ship is used to transport LNG tank containers, then transportation can be performed, but the ship cannot sail in shallow waters such as inland rivers or coastal waters and requires dedicated port facilities
Solution Approach 1:
The ship integrates multiple functions into a single vessel: it combines cargo transport capabilities with onboard loading/unloading facilities (crane and storage tanks). This allows the ship to operate in shallow waters without requiring dedicated port infrastructure, as it can perform both transportation and cargo handling operations independently.
Solution Approach 2:
The ship acts as an intermediary between LNG supply sources and remote consumption areas. By equipping the vessel with onboard storage tanks and loading/unloading equipment, it mediates the transportation process, enabling LNG delivery to locations that lack direct pipeline infrastructure or dedicated port facilities.
2Reliability
If separate stationary storage tanks and cargo handling facilities are installed at remote places, then LNG can be supplied to those areas, but construction costs increase and the transportation process becomes complicated
Solution Approach 1:
The patent extracts the cargo handling facilities (storage tanks, loading/unloading equipment, crane) from the destination port infrastructure and relocates them onto the transportation vessel itself. This eliminates the need to construct separate handling facilities at remote destinations, simplifying the overall system while maintaining reliable LNG supply capability.
Solution Approach 2:
The ship becomes self-sufficient by carrying its own cargo handling equipment and storage facilities. It can independently perform loading, transportation, and unloading operations without requiring external port infrastructure, thereby reducing the complexity of the transportation process and eliminating the need for complicated coordination with destination facilities.
3Reliability
If new gas supply infrastructure such as gas pipeline networks is constructed, then LNG can be supplied to remote areas, but opposition from local residents and existing facility occupation make construction impossible
Solution Approach 1:
The ship serves as a mobile intermediary infrastructure that replaces the need for fixed pipeline networks. By bringing storage and loading/unloading capabilities directly to the destination, it provides an alternative solution that avoids the social and logistical challenges of constructing new gas supply infrastructure in occupied or opposition-prone areas.

AI summary
The present invention relates to a container transportation ship. More particularly, the present invention relates to a container transportation ship for transporting containers, characterized in that a loading space in which at least one container is loaded and a loading/unloading space configured such that an external transfer means can directly enter/exit in order to load and unload the container, are delimited on the deck of the container transportation ship; and a crane is provided to move the container in the longitudinal direction of the container transportation ship, in the transverse direction thereof, and in the upward/downward direction thereof for the purpose of loading the container on the external transfer means that has entered the loading/unloading space or unloading the container from the external transfer means.
