Support BOP Test Station Improvements

Aiken Completed the following scope: INVESTIGATE A 150 HP MOTOR STARTUP UNDER LOAD ISSUE. The 480V connections were not properly insulated so wire conductors arc’ed against the motor starter panel. Also, the VFD was undersized. Proper insulation was applied and the VFDs were replaced with correctly specified VFDs. CALIBRATE 2 REGULATOR ASSEMBLIES. A 4-20 mA signal was scaled by 83% […]

Projectile Containment Test Cell with Pneumatic-Electric-Magnetic Door Lock System

Aiken first completed calculations for a projectile containment test cell based on a specified pressure test failure and design-basis projectile. Aiken then created construction and foundation drawings for the test cell of a specific size and with a specific door configuration. Aiken fabricated and installed this structure in an approximately 2 month time period. The test cell internal dimensions […]

Analysis of Hydraulic Torque Fixture for BOP Assembly and Disassembly

A fixture which applies a very large torque to an assembly was analyzed and documented. On site measurements were taken to gather analysis and drawing information. A usage history write-up was created to investigate forces, torqued equipment size/type variations, reasons for fixture use, the condition of equipment that the load is applied to, and more. […]
