Alphatec applied its expertise on the issues of skid perimeter grouting, skid fill, and pressure injection.
For the customer Petrofac Facilities and Management Ltd, and end user Total E&P UK, Shetland Gas Plant, Alphatec had to implement its grouting expertise on problematic units.
The units in question are high-pressure SPX/Clyde Union 5-cylinder plunger pumps, driven by ABB electric motors of 420 kW, through a David Brown gearbox, operating at 238 rpm. All three elements are mounted on a fabricated steel skid, with approximate dimensions of 8.2 x 3.3 x 0.3m. The units were manufactured and installed in 2015, but have been suffering from vibration issues since start-up, and are in MEG injection service.
