Crown Deck Lighting Assembly With Rotatable Fixtures for Rig Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drilling rigs operate 24/7, necessitating operations in inadequate illumination, posing safety risks for personnel and equipment due to insufficient lighting during idle periods.
Innovation Solution
A crown deck lighting system (CDL) mounted on the rig, providing comprehensive illumination of the rig site through adjustable light fixture assemblies, ensuring safety during operations and transportability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If drilling rigs operate 24 hours a day, then productivity increases, but safety deteriorates due to inadequate illumination during nighttime operations
Solution Approach 1:
The lighting system employs adjustable light fixture assemblies that can be rotated between stowed and deployed positions, and tilted to adjust beam direction. This dynamic capability allows the system to adapt to different operational conditions and lighting requirements throughout 24-hour operations, maintaining safety while enabling continuous productivity
Solution Approach 2:
The lighting system is divided into multiple independent light fixture assemblies distributed around the crown deck perimeter. Each assembly can be independently adjusted and positioned, providing comprehensive coverage of the rig site while allowing flexible configuration for different operational scenarios, thereby maintaining both safety and productivity
2Reliability
If lighting fixtures are permanently mounted on the crown deck, then illumination reliability improves, but transportability deteriorates
Solution Approach 1:
The light fixture assemblies are designed with rotational joints allowing them to be moved between deployed positions for illumination and stowed positions for transport. This dynamic reconfigurability enables the system to provide reliable illumination during operations while being easily transported to different rig locations, resolving the contradiction between reliability and adaptability
Solution Approach 2:
The light fixture assemblies are positioned within or near the crown deck structure, allowing them to be integrated into the overall rig assembly. When not in use, they can be retracted or positioned to minimize space requirements, enabling transportability while maintaining illumination reliability during operations
3Area of stationary object
If light fixture assemblies are positioned far from the crown deck perimeter, then illumination coverage improves, but structural complexity increases
Solution Approach 1:
The crown deck handrail structure serves dual purposes: as a safety barrier and as the mounting support for the light fixture assemblies. By utilizing the existing handrail structure for both its original function and as a lighting support, the system achieves wide illumination coverage without adding separate complex support structures, thereby reducing overall device complexity

AI summary
A system that can include a crown deck with a handrail positioned along an outer perimeter, a support structure mounted to the crown deck, where the support structure can horizontal supports rigidly attached to vertical supports, the horizontal supports being supported at a vertical elevation above the crown deck by the vertical supports, which are welded to a top surface of the crown deck, with light fixture assemblies mounted to the horizontal supports, with each one of the light fixture assemblies being rotatable, relative to the horizontal supports, between a stowed position and a deployed position, where the stowed position locates a respective one of the light fixture assemblies radially spaced away from the outer perimeter of the crown deck and toward a center of the crown deck.
