Solution Overview

Problem

The deployment of offshore floating wind turbine platforms is challenging due to their size and weight, requiring costly permanent infrastructure modifications or expensive submersible barges, and existing quays lack the necessary infrastructure for efficient deployment.

Innovation Solution

A relocatable quay system with an elevator system that can raise and lower a deck to receive and deploy floating units, equipped with features like ballast compartments and jack-up systems to adjust to water levels and tides, allowing for horizontal transfer and separation from the deck.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If permanent tailormade equipment is built into the stationary quay to handle deployment, then deployment capability is improved, but infrastructure cost and complexity increase

Engineering Contradiction:
Improvedeployment capabilityVSAvoidinfrastructure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The deployment system is divided into separate functional modules: a relocatable quay unit with deck and elevator system that can be positioned independently of the stationary quay. This segmentation allows the deployment equipment to be moved to different locations without modifying the permanent infrastructure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The quay is designed with dynamic characteristics - the deck can be raised and lowered by the elevator system, and the entire relocatable quay can be moved to different positions. This dynamic capability enables the same equipment to adapt to various deployment scenarios without permanent modifications.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If submersible barges are used to deploy floating platforms, then deployment capability is improved, but operational cost increases

Engineering Contradiction:
Improvedeployment capabilityVSAvoidoperational cost
Core Design Contradiction:
Ease of operationVSQuantity of substance

Solution Approach 1:

The relocatable quay uses a cost-effective design that replaces expensive submersible barges. The deck and elevator system provide a more economical solution for deploying floating platforms, reducing operational costs while maintaining deployment capability.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

3Adaptability or versatility

If the quay is made relocatable to serve multiple locations, then versatility is improved, but device complexity increases

Engineering Contradiction:
ImproverelocatabilityVSAvoidquay system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The quay system is segmented into movable and stationary components. The deck and elevator system form a relocatable unit that can be transported to different locations, while the stationary quay provides fixed support infrastructure. This segmentation enables versatility without requiring the entire system to be complex and movable.

Inventive Principle:
Principle #1Segmentation

AI summary

A relocatable quay includes a deck that is relocatable in a body of water adjacent a stationary quay. The deck is positioned at the stationary quay to receive a floating unit. The relocatable quay also includes an elevator system positionable to raise and lower the deck to receive the floating unit from the stationary quay and to deploy the floating unit into the body of water.
