HA OPERATION AND MAINTENANCE 7/2019 HEC HA Blowout Preventers are simple to operate and proven effective at meeting the demanding pressure control requirements of drilling industry. It is highly recommended to perform periodic inspections of rubber, seals, and over – all integrity of the blowout preventer to reduce the risk of problems in a well control situation. INSTALLATION INSPECTION and INSTALL RECOMMENDATIONS It is recommended to install the H A blowout preventer using: 1. A control line to the closing (lower) port 2. A control line to the opening (upper) port 3. An accumulator bottle in the closing line for stripping. This bottle should be pre – charged to 500 psi for surface applications and 500 psi plus – sea applications 4. A hydraulic regulator to allow adjustment of operating pressure 5. F or an water soluble oil /water mix is acceptable Inspect for any damage to the top and bottom ring grooves. Clean the ring grooves with emery cloth and lightly oil prior to pl acing ring gaskets into place. ALWAYS replace ring gaskets when preventer is removed from a job site and reinstalled. Inspect studs and nuts for any damage. Replace any stud that is shorter than required to maintain full thread engagement or has thread dam age . Inspect all studs and nuts for tightness when the preventer is in use. Prolonged intervals of non – operation and no lubrication will cause seals to freeze up and possibly break or lock up the preventer. OPEN and CLOSE OPERATIONS HEC HA models are des igned to operate with any 1,500 psi approved hydraulic oil field system. A HA blowout preventer must be operated using hydraulic pressure. A ll models available from HEC can close and seal with no pressure adjustments on various casing sizes using 1,500 psi except the 13 – . On 13 – t is recommended to use the table be low for pressure adjustments when closing on the listed casing sizes to prevent damage to casing from sealing element segments maki ng contact with casing. Table 7: 13 – Casing Size (inches) 13 – 7 7 – 5/8 8 – 5/8 9 – 5/8 10 – 3/4 11 – 3/8 Adjusted psi 1,500 1,255 890 615 415 280 When hydraulic pressure is pumped into the closing chamber, the pisto n rises, forcing the element up. The spherical shape causes the element to close as it moves upward. Steel segments in the rubber support both the rubber and the drill string by containing the pressure below and providing a seal around the pipe. When there is no drill string present, the piston will continue to rise which forces the rubber element to seal on an open bore. The steel segments inside the element further aid in providing support to contain the well bore pressure. STRIPPING Stripping operation s are one of the most severe applications for any preventer because of the extreme stress the rubber element is exposed to when the drill string is moved through the preventer. A HA blowout preventer can offer a long stripping life if maintained and operat ed properly. Onl y the top portion of the HEC Kelly or string. The large reservoir of rubber allows the user to strip in and out of deep hole without replacing the element on the job site . The Recommended proce dure for stripping is: 1. Close the preventer with a maximum of 1,500 psi closing pressure unless otherwise recommended from the above table 2. Prior to initializing the stripping operation, reduce the closing pressure to a value sufficient to allow a slight lea k 3. Stripping should be done with a slight leak to provide lubrication and prevent excessive temperature buildup if conditions allow. As the sealing element wears, the closing pressure will need to be increased to prevent excessive leakage 4. If conditions do not allow leakage during stripping operations, closing pressure should be adjusted to a value sufficient to maintain a seal 5. If closing pressures approach 1,500 psi on the hydraulic close line, consideration should be given to switch to a different prevente r or new sealing element as the rubber may be worn and could cause further damage to the valve. Keep in mind, the minimum pressure required to maintain a seal during stripping, may vary depending on the sealing element and its service history.

HA OPERATION AND MAINTENANCE 7/2019 MAINTANANCE After 6 months or at the end of drilling of well, operate the packing element by pumping hydraulic oil into the close port an d wash grease and mud from around the packing element. Continue to operate the packing element (open & close hydraulic) while wash ing out packing element and through the bore of the BOP stack. Grease top of the packing element if possible and open completely. OPERATING CAPACITY HA Blowout Preventers can be operated via hydraulic connection ports located on each side of the lower b ody. Fluid capacities and body fitti ng sizes are listed in table 8 . STUD TORQUE When installing lid on HA Blowout Preventer, the bolts should be torq ued in the order shown in Figure 13.

Buyer agrees to notify HEC in writing of any clam, da mage, defects, deficiencies, or failures in performance within 30 days of the event giving rise to the claim, damage, defects , deficiencies, or failures. To the extent they may validly do so, the parties agree that the Work will be deemed to be fully a ccep ted without defect if no notice as required herein is received by HEC within 12 months of the completion of Work. Final Inspection, Delivery and Acceptance . Inspection and acceptance of Product or Work must be made at HEC ‘s plant or other shipping or recei ving point designated by HEC and shall be conclusive except as regards latent defects. Delivery shall be in acceptance with the requirements in the Work Order , provided, in the event Buyer is unable to accept delivery upon completion of the Work in accorda nce with such requirements, Buyer agrees that (i) title and risk of ownership shall pass to Buyer on date of HEC ‘s invoice, and (ii) Buyer will make payments within thirty (30) days after date of such invoice. HEC shall retain custodial risk of loss until delivery is made in accordance with such requirements. Shipment schedules are given as accurately as conditions permit and every effort will be made to make shipments as scheduled. HEC will not be responsible for deviations in meeting shipping schedules no r for any losses or damages to Buyer (or any third party) occasioned by deviations in the shipping schedule, whether due to A cts of God, orders bearing priority ratings established pursuant to law, fire, flood, shortages or failure of raw materials, suppli es, fuel, power or transportation, breakdown of equipment or any other cause beyond HEC ‘s reasonable control whether of similar or dissimilar nature than those enumerated. HEC shall have additional time within which to perform as may be reasonably necessar y under the circumstances and shall have the right to apportion its production among its Buyers in such a manner as it may co nsider to be equitable. HEC reserves the right to furnish commercially equivalent or better substitutes for materials or to subcont ract the Buyer’s order or portions thereof as HEC deems necessary. In no event shall HEC be liable for any consequential damages resulting from failure or delay in shipment. If Buyer requires drawings, procedures, standards, or similar material for approva l, shipping schedules are based on HEC having all required information and a firm order from Buyer which is enterable into production. Any hold points, witness poin ts or the need for inspection by Buyer’s representatives must be identified by Buyer at the time of quotation (if any) and/or placement in order that the effect on the prices or shipping schedules (if any) can be taken into account. Additional inspection or testing required by Buyer which affects normal product ion sequence will be considered as e xtending the shipping dates accordingly. Limitation of Liability . Buyer acknowledges that it is the Buyer’s responsibility to maintain the product manufactured, remanufactured or tested by HEC in accordance with the industry standards including but not lim ited to function testing of the Product. Buyer acknowledges that in the event any defect or damage occurs from Buyer’s use of the product serviced by HEC , Buyer holds HEC harmless for any and all failures and agrees to indemnify HEC against claims by third parties for damages that are not resulting from the acts or negligence of HEC . Buyer agrees to hold HEC harmless from and against all claims, demands, losses, damages and causes of action of whatever kind or nature for loss of or damage to property arisin g from or attributable to the negligence of Buyer.
