Offshore Wind Vessel With Sliding Deck And Support Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for installing offshore wind power generators are costly and time-consuming, especially in deep water environments, due to the need for open-sea assembly using jack-up barges and cranes, which pose safety risks and increase worker fatigue.
Innovation Solution
A specialized vessel with a support frame, sliding deck, and spuds that allows for assembly and loading of the wind power generator at a shore-based facility, enabling stable transportation and installation with reduced interference from cables and minimal worker involvement, using a suction pile method to stabilize the substructure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If open-sea assembly using jack-up barge and cranes is used, then wind power generator can be assembled on the sea, but installation cost becomes excessive and installation time becomes long
Solution Approach 1:
The invention applies preliminary action by assembling the wind power generator on land (quay wall or harbor) before transporting it to the installation site. The entire structure including substructure and turbine is pre-assembled onshore, then loaded onto a specialized vessel for transport and direct installation at the target location, eliminating the time-consuming open-sea assembly process
Solution Approach 2:
The invention merges transportation and installation functions into a single specialized vessel. The vessel is designed to both transport the pre-assembled wind power generator and perform the installation operation, combining what were previously separate operations (land assembly, sea transport, sea installation) into an integrated process that reduces overall installation time
2Adaptability or versatility
If open-sea assembly using jack-up barge and cranes is used, then wind power generator can be assembled on the sea, but installation cost becomes excessive
Solution Approach 1:
By performing assembly operations on land where conditions are more favorable and less costly, the invention reduces the expensive sea-based operations to only transportation and final installation. The preliminary assembly on quay wall or harbor avoids the high costs associated with deploying jack-up barges and specialized cranes in open sea conditions
Solution Approach 2:
The invention replaces the complex mechanical system of jack-up barges and multiple cranes with a simpler, integrated vessel design that has built-in lifting and installation capabilities. This substitution of the entire installation system with a purpose-built vessel reduces operational costs and simplifies the installation process
3Adaptability or versatility
If water depth is large, then wind power generator can be installed in deep water locations, but safety and fatigue of workers deteriorate due to long-period work time
Solution Approach 1:
The invention addresses worker safety by completing the complex assembly work on land where workers are in a stable, controlled environment rather than working from unstable platforms in deep water. The preliminary assembly onshore eliminates prolonged exposure to harsh marine conditions, reducing fatigue and safety risks while still enabling deep water installations through the vessel transport capability
