Alphatec on the Shell Capsa Thomassen Compressor

By Alphatec Engineering

Alphatec shares how it delivered foundation repairs, and regrout for motor and compressor unit k2701-2 for one of its many customers, Shell CAPSA, Buenos Aires.

The challenge featured a four cylinder reciprocating C25-4 Howden Thomassen compressor, with direct coupling through an inertia wheel to a Siemens electrical motor, Pn=1,750kW working at 372rpm.; total weight 60 Tn. The foundation seemed to be constructed from a sole block with two sections of different hight: one for the crankcase and cylinder supports and the other (lower) for the motor. Both sections rested on top of an underground mat, 900 mm. in thickness and with 9 x 7,2 m. according to the drawings provided.
