Integrated Offshore Lay Arrangement Reducing Mobilization Complexity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity and time required for installation and configuration of separate equipment for laying products like pipes and umbilicals offshore are increased due to the need for multiple, non-integrated pieces of equipment.
Innovation Solution
A single, integrated device is developed that includes a base for mounting and integrating a movable lay chute, hang-off clamp, work table, access platform, product support arm, and fixed chute, allowing for self-contained installation and operation on a vessel, with features like adjustable A-frame length and hydraulic rams for optimal positioning and movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate pieces of equipment (A-frame, crane, chute, hang-off clamp, work table) are used for product laying, then each component can perform its specific function, but the complexity and time required for installation and configuration increases
Solution Approach 1:
The patent combines multiple separate equipment components (A-frame, crane, chute, hang-off clamp, work table) into a single integrated device. The base structure supports all these functions in one unified system, eliminating the need for multiple separate installations while maintaining all necessary functional capabilities for product laying operations.
Solution Approach 2:
The integrated device performs multiple functions simultaneously - it serves as an A-frame for lifting, a crane for positioning, a chute for guiding products, a hang-off clamp for securing, and a work table for operations. This multi-functional design reduces the number of separate equipment pieces needed while maintaining full operational capability.
2Reliability
If separate pieces of equipment are used for product laying, then each component can be optimized for its specific function, but the time required for installation and configuration increases
Solution Approach 1:
By merging all necessary components into one integrated device, the installation process is streamlined from multiple separate installations to a single installation event. The base supports all components in predetermined positions, significantly reducing the time required for mobilization and setup while maintaining reliable functional performance of each component.
3Adaptability or versatility
If multiple separate equipment pieces are used, then functional capabilities are comprehensive, but the level of complexity for vessel mobilization increases
Solution Approach 1:
The integration of all equipment components onto a single base simplifies vessel mobilization. Instead of handling and installing multiple separate heavy equipment pieces, the entire system is mobilized as one unit, reducing the complexity of logistics, installation procedures, and coordination required on the vessel.
