Amarinth completes pump test facility, improving procedures and throughput

22 June 2011

Amarinth has completed the installation of a new test facility at its Suffolk site, providing additional capacity to handle a growing order book. A new building at the Rendlesham site now houses the new test facility, which is expected to lead to improvements in delivery times, as well as providing a safe environment for the test site personnel and assurance that pumps are not damaged during test procedures.

The new facility has a comprehensive test rig with multiple connections to the main test tank, which can cope with flows of up to 1,650m3/hr. The multiple connections allow pumps to be prepared for test or disassembled after tests whilst another pump is undergoing testing, saving hours of idle test time and increasing throughput significantly.
 
The test process is fully automated, with electronic valve actuators enabling the whole rig to be controlled via a single push button at the master test desk. All test parameters are captured electronically using modern digital test and data acquisition instrumentation, and delivered directly to the test desk.

 
Large vertical pumps provide a real challenge for most manufactures to test. In the new facility Amarinth has constructed two 5m deep sumps allowing for full length testing of vertical sump pumps up to 7m. Again, one pump can be prepared whilst the other pump is under test. An hydraulic system is used to lower the pumps into position - all at the push of a button - avoiding the need for cranes and enabling the job to be completed safely by just one operator.


Building on its web-enabled order processing and documentation systems, Amarinth has also embraced the internet for pump testing. Using web video cameras on the test rigs, witness testing can now be carried out without the inspector or the customer travelling to the factory. Video witnessing of pump testing is now being allowed under the latest issue of the API 610 standard (ISO13709).
 
Indeed, Amarinth used video witness testing to good effect on a recent contract from Larsen & Toubro for low shear API 610 OH2 A-series centrifugal pumps destined for an existing Produced Water Treatment Plant on a platform in the Mumbai High North field in the Arabian Sea, operated by the Oil and Natural Gas Corporation.

When it came to testing the pumps, delays waiting for visas to be granted was impacting the critical path and threatening delivery.

Using the web video camera, the test process was witnessed over the Internet in the presence of Larsen & Toubro’s designated inspector from Bureau Veritas Inspection agency. This proved very successful and enabled the pumps to be tested on-time. Additionally, a significant cost saving was made by removing the need for someone to come over from India.
