    CSPP Capacitor Charging Unit Operation Manual CSP-CSPP-8000/2 _________________________________________________________________________________________________________ SECTION 1 - OPERATIONAL 1. Environmental Considerations Seismic Sound Sources And Marine Life Although not proven, there is concern in some quarters that marine mammals may be harmed or their behaviour changed by seismic activity. The sound pulses from sparkers and boomers is much lower in amplitude and higher in frequency (so it will travel less far) than air guns.

    CSPP Capacitor Charging Unit Operation Manual CSP-CSPP-8000/2 _________________________________________________________________________________________________________ 2. Introduction This manual covers the CSP-P model available from AAE. The CSP-P is based on the highly proven CSP-300, the CSP-P has a high voltage charger rated at 1500 joules per second, and can supply up to 350 joules of energy per shot into boomer and sparker loads.

  • Page 7: Installation

    CSPP Capacitor Charging Unit Operation Manual CSP-CSPP-8000/2 _________________________________________________________________________________________________________ 3. Installation Siting the CSP-P The CSP-P units can deliver high energy, high voltage pulses, yet still emit minimal electrical emissions, and so can carry the CE mark. The CE marking ensure that the CSP-P‟s can be sited next to sensitive electronic equipment which carry their own CE marking (for susceptibility to emissions) and will be unlikely to cause them interference.
  • Page 8 CSPP Capacitor Charging Unit Operation Manual CSP-CSPP-8000/2 _________________________________________________________________________________________________________ Earthing All CSP-P‟s MUST be earthed. The M8 earth bolt on the front panel should be connected to the vessel earth by a heavy gauge wire or cable. On larger ships, earth is usually a steel bulkhead, but for smaller fibre glass / wooden vessels a sea earth is necessary.
