ONGC case study

Magcat reduced cleaning frequency, cut chemical use, and kept offshore compressors running longer between shutdowns.

Client: ONGC
Region: India
Application: Offshore compressor cooling systems
Sector: Oil & gas
Product: Magcat water conditioner

ONGC (Oil and Natural Gas Corporation) is India’s largest oil and gas exploration and production company. On its offshore rigs, seawater is used to cool compressors, but high hardness levels quickly cause fouling and scale build-up.

The challenge

Compressors needed frequent cleaning due to heavy scale deposits from seawater cooling

One unit required cleaning every 65 operating hours, another every 172 hours

Cleaning involved shipping chemicals offshore, using large amounts of manpower, and taking compressors offline

This meant higher costs, logistical challenges, and reduced availability of critical equipment

The solution

Magcat conditioners were installed on the cooling water inlets of two compressors. Cleaning frequency and run time were monitored before and after installation.
