Supporting complex pipeline repairs
What happened
Firstgas executed a complex wrinkle remediation on a major transmission pipeline using STATS BISEP live isolation while maintaining continuous gas flow. The campaign deployed two 30” BISEP units about 500m apart, used an integrated 12” bypass and sustained leak‑tight double-block-and-bleed isolation at pressure for an extended period. This demonstrates verified live-isolation plus bypass is operationally real; watch whether other operators replicate rental/service models and how suppliers set mobilisation pricing
Why the category manager should care
Treat BISEP-capable vendors as strategic for integrity campaigns because verified DBB isolation reduces the need for shutdowns and changes how mobilisation and contract terms should be structured
Key facts
- Two 30” BISEP units deployed approximately 500m apart
- Integrated bypass maintained continuous flow via a 12” bypass line
- DBB isolation sustained leak‑tight performance on a live transmission pipeline at operating p
