LMF COMPRESSOR

A request has been sent to LMF for a technical solution and a quotation regarding a mobile system for a compressor used for marine seismic operation. The main requirement is constrained by the capacity which should be at minimum 10.4 m³/min free air, corresponding of the current compressor on R/V Håkon Mosby.

The technical answer proposed by LMF is:

High Pressure Compound Compressor LMF 11sL/138-207 E60 Piston Compressor BS102-309 S21

A capacity of 11 m³/min (390 cfm) and a discharge pressure of 138 barg (2000 Psig) or 207 barg (3000 psig). [Using atmospheric pressure as reference is usually signified by a "g" for gauge after the pressure unit.]
