Power Cable Replacements
Project Location:
Port Talbot, Wales
Client Name:
TATA Steel
Project Description:
OCU supplied and installed new power cables following a fire in the west basement at Tata Steel’s Port Talbot Hot Rolling Plant, which caused significant damage to existing assets.
The works included installing seven 3.3kV three-core cables and one 11kV three-core cable, each approximately 500m in length. Cables were routed from the 3.3kV descaling substation switchgear, through the pumphouse and along the scale crane gantry before terminating in the Dirty Water Return (DWR) drive room. The scope also included all associated containment, jointing, termination, testing and commissioning.
Key Stats:
8 x 500m power cables installed
3.3kV and 11kV cable systems
Full supply, installation, jointing and testing delivered
Works completed within a live industrial environment
3 Months
Duration
Challenge
Complex cable routing through existing cable basements and over the scale crane gantry
Restricted access requiring specialist scaffolding without disrupting production operations
Scale crane isolation required to allow safe access to the gantry
Challenging environmental conditions, including continuous flooding within the cable basement due to a damaged pipe
Solution
Undertook detailed cable route surveys to identify existing services, interfaces and support locations
Utilised existing penetrations and routes to minimise additional civils and reduce impact on live operations
Designed and installed bespoke scaffolding to provide safe access to the crane gantry
Planned works around agreed production windows, allowing temporary isolation and emptying of the scale pond without affecting overall output
Outcome
Critical Dirty Water Return power infrastructure successfully reinstated
Works delivered safely within a live production environment
High safety and environmental standards maintained throughout
Full project scope completed on time and within budget
