Custom-Built Triple Williams Air Driven Pump Skid
A bespoke triple-pump chemical injection skid designed for high-reliability dosing and safe operation across demanding offshore conditions.
The Challenge / Background
The operator required a bespoke triple-pump skid capable of delivering reliable chemical injection in an extremely cold environment. Low ambient temperatures risked increasing the chemical’s viscosity, which would slow flow rates and affect pump performance. A robust solution was needed to maintain fluidity and ensure each pump could operate consistently in harsh conditions.
The Solution
PPM designed and built a custom triple Williams air-driven pump skid with full trace heating applied to all critical pipework and pump bodies. The heating maintained chemical temperature, preventing thickening and ensuring stable flow under low-temperature conditions.
Key elements included:
- Triple Williams air-driven pump arrangement for duty/standby/backup flexibility
- Full trace-heated pipework and pump assemblies to protect chemical viscosity
- Temperature-resistant insulation and routing design for cold-weather reliability
- Integrated instrumentation to monitor delivery pressure and flow
- Stainless-steel skid frame engineered for easy site installation
Delivery & Execution
The skid was assembled and fully tested in-house, including verification of the trace-heating performance under simulated cold-weather conditions. All electrical heating elements, insulation, and control links were checked for uniform temperature maintenance before final sign-off. The unit was delivered ready for immediate deployment.
Outcome & Impact
The client received a fully engineered injection skid capable of operating reliably in extremely low temperatures. With the trace-heated system preventing chemical thickening, the pumps achieved stable performance, reduced downtime, and consistent injection rates throughout winter conditions.
