blow count limit for offshore hammers

[r2d22]

Hi,
Do you know if there is a limitation for the max. BPF for offshore hammers?. Sometimes I have read 240 BPF and others 150 BPF. Is this a specification from the manufacturer of the hammer?. Thanks

IHC has set limits for their hammers. Don't have them at hand.
