24” By 24” (24” DOUBLE BLOCK AND BLEED / STOPPLE AND HOT TAP SERVICES AT OB/OB GAS PLANT for Nigerian Agip Oil Company LTD (NAOC)

The OB/OB Gas Plant project presented a multifaceted challenge, involving the isolation and intervention of multiple pipeline sections under high-pressure conditions. Hyotem was entrusted with executing a 12” x 4” Hot Tap on the Low-Pressure (LP) Flare Header, a 10” x 6” Hot Tap on the Ebocha Pipeline, and a 24” x 24” High-Pressure Line Double Block and Bleed, STOPPLE®, and Hot Tap Services. These tasks were complicated by varying pipeline diameters and the imperative to eschew traditional methods like venting, flaring, and blowdown, which often entail significant environmental risks and operational downtime.
