Benefits

 The Hydril Sentry blowout preventer is a hydraulically operated unit designed to be light, small, cost-effective, and easy to maintain to help any land or jackup rig system operate more efficiently and competitively. Highlights include:

 1. Extreme cold/hot temperature tested to: ¡ Blind shear 30/350°F ¡ Fixed bore 30/300°F ¡ Variable 40/250°F

 2.  API 16A, 4th Edition PR2 compliant

 3.  Hydrostatic testing to 15,000 psi

 4.  The highest shear force of similar-sized products in the market at 813,000 lbs

 5.  Lower Total Cost of Ownership

Key features

1. The Hydril Sentry design encompasses features critical
to the land and jack up the market. The ram blocks are removed via a dedicated
ram access doors. In addition, a tandem operator is
used to maximize the closing force with minimal size
requirements.

2.  Ram blocks can be removed, inspected, re-dressed,
and re-installed without breaking the bonnet door seal.

3.  Ram blocks are 1 in. shorter and 30% lighter than
previous designs. The fixed and variable seals remain
unchanged from their proven designs; minimizing
potential discrepancies in spare inventory management.

4.  Ram access bolting torque requirements are 1,750 ft-lb,
less than half of the 4,000 ft-lb required to torque the
conventional bonnet bolts.

5.  Faster lead times supported by a product-specific,
streamlined supply chain process.

6. The conventional 19 in. operator has been replaced by a
13.5 in. diameter tandem operator. The tandem operator
is 25% shorter and 50% lighter while still providing the
same shear capabilities at all pressure ratings.

7.  Control tubing is ported directly to the operators,
reducing the number of pressure connections required
for operation.

8.  The Hydril Sentry weighs 35% less, is 5% shorter, has
25% fewer part numbers, and 36% fewer components
than the previous 13 in.
