Stage 2: Lock the connector on stump and P-test.Stage 1: Lock the connector on stump then remove the locking pressure then P-test.High Pressure test: Hydrostatic proof test value – Hold minimum 10 minutes after stabilization Low pressure test: 200 – 300 psi – hold minimum 10 minutes after stabilization. The hydraulic operating chamber pressure to be equal to or less than manufacturer’s specification. Ram to be tested at Low and High Pressure, engage ram locks after rams are closed, then remove operating pressure.Įach hydraulic connector to be P-tested at Low pressure and at hydrostatic proof test. The closed preventer test for BOP equipped with ram locking system shall be P-tested with ram locking system engaged. Low Pressure: 200-300psi, minimum holding 10minutes after stabilization. The timing shall not start until the test pressure stabilizes within manufacturer’s specified range and the external surfaces have been thoroughly dried.Īll rams & annular to be closed-preventer tested after hydrostatic proof test. Pressure up and hold for minimum 15 minutes.Initial pressure holding for minimum 3 minutes.Hydrostatic Proof & Hydraulic Operating Chamber Tests Hydraulic operating system test shall be administered on each ASSEMBLED BOP and Connector, including any hydraulic locking chambers. Test shall include the ring gasket surface areas on each ends of the body.Lowest RWP part of the equipment shall be used as the RWP for the equipment.Drill through equipment shall be tested with sealing mechanism open – if applicable.Any additives shall be recorded in the test records. ![]() according to API-16A 4th edition, and API-16AR temperature classification. Water, water with additives, or dielectric fluid shall be used as test fluid. WellProtek is Freudenberg Oil & Gas Technologies line of API-16A licensed.All drill through equipment shall be subjected to a hydrostatic proof test prior to shipment from factory.Drift mandrel GAUGE LENGTH (which may be different from overall length) shall be at least 2” longer than any CAVITY that intersects the well bore, but not less than 12” è GAUGE LENGTH minimum 12” and minimum 2” longer than any CAVITY intersecting well bore.Drift to pass through bore of test objects.Ram BOP – Annular BOP – Hydraulic Connectors – Drilling Spools – Adapters.Maximum allowable test pressure above RWP is 5% of RWP or 500psi whichever is less.Īfter test and prior to shipment: Water or water with additives test fluid should be drained and replaced with a corrosion-inhibiting fluid. The quality control requirements for assembled equipment includes:ĭrift test – Pressure test – Hydraulic operating system tests To help those who may be in similar situation, hereafter I extract the Factory Acceptance Test guide from API 16 A 4th edition – the latest edition to this point for your convenience.ĪSSEMBLED EQUIPMENT FACTORY ACCEPTANCE TEST – FATĪssembled equipment includes bonnet or door assemblies when shipped separately from a BOP. The most recent edition contains changes that will drive a significant amount of rigorous testing to monogram pressure-control equipment going forward. This includes ram and annular blowout preventers as well as connectors, spools, and adapters. I spent ages working with a BOP manufacturers to get a common ground on this but things seem so hard going through manufacturer specification and API standards. Abstract API Specification 16A defines the requirements for design, testing, and other aspects of drill-through equipment. Second Edition – TG Work Continues 1220 L Street, NW ģ Current Activities “Success Path” Evaluation of CT Well Control Barriers Completed Recommended Changes in CT Unit Accumulator Configuration Adopted (Compliance with API Spec 16D) Scheduled WebEx Meetings Focused on Revising Section Text by 4th Qtr.If you happen to buy a new BOP from manufacturer definitely Factory Acceptance Test is an indispensable step.
