BOP testing system en route to drillship

February 2018

BOP testing at Calder facility

This BOP testing system was designed, built and tested under one roof at our factory in Worcester, UK.

Commissioned by a major oil & gas well service company, this blowout preventer (BOP) testing system will be used to test the sealing arrangements of BOPs and will operate in an ATEX Zone 2, hazardous environment on-board a drillship.

At the heart of the BOP test system is the Hammelmann high pressure reciprocating plunger pump. Power is supplied through an ATEX Zone 2 compliant electric motor enabling the unit to achieve test pressures of up to 345 bar (5,000 psi). A self-contained mixing tank is used to prepare the test water to suit the prevailing environmental conditions. A stand-alone accumulator skid allows the pressure to build to preset levels ready for a sudden, controlled release of test water into the blowout preventer.

The scope of supply includes a complete control system package. An on-board HMI controls the three operational phases: initial tank filling; mixing procedure to various ratios; and the high pressure injection. The HMI features a fault-monitoring system, and clearly displays the operating parameters.

Each unit of the BOP test system is mounted in a crash frame which offers the dual benefits of being lightweight and providing a high level of protection during transport operations. The crash frame has lifting eyes and fork-lift slots, and a spill-containment/bund feature.

This BOP testing system was designed, built and tested under one roof at our factory in Worcester, UK.

Factory acceptance testing was carried out in our in-house test bay and was witnessed by the customer.
