Client SoW
Client requested that an access way was required on the side of existing catwalk. The access way had to incorporate significant loading capabilities; and be totally flat level with the top steel of the catwalk.
Client Requirements Summary
- Flat – allowing pipe to be rolled over it
- Load capacity >2Te/m2
- Slip resistant for personnel in transit
- Light weight piece-small assembly
- Quick / easy to assemble by deck crew
Solution
A solution was devised meeting all the Clients requirements. It was carefully managed to ensure the Clients requirements were not over engineered – as this costs time and money.
The solution we devised uses a simple arrangement with mechanical locking and easily accessible pins (rather than conventional nuts/bolts).
The outrigging steelwork is pinned into position, and infill covers positioned. The covers are all interchangeable, allowing the ease of installation and/or replacement. The benefit of this approach has multiple ‘standard’ parts; not a multitude of ‘unique’ parts that only fit into unique positions.
Each individual component is light weight; allowing a single person to easily construct the assembly in less than 1 hour.
The solution was also delivered 16% under the original estimate.
