Section 1 - OPERATIONAL
1.1. 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. However it makes sense that a precautionary approach to emitting
sounds in the whales and dolphins’ natural habitat should be observed.
The CSP energy sources described in this manual have the ability to “soft-start” and
increase the energy emitted in the water slowly over time and this technique will give
any marine mammals nearby the opportunity to escape before maximum signal
amplitude is reached. It will also give them a chance to get used to the noise if they
choose to stay (!) rather than being subjected to a sudden shock of a full power
seismic signal.
The procedure is quite simple:-
By using a slow repetition rate –say at 1 pulse per 15 seconds and by using the “Auto”
charge rate, the energy will slowly increase over the course of several minutes. Once full
power has been achieved, the repetition rate can then be slowly increased until the
rate desired for the survey has been achieved.
Another factor to consider is to ensure that the start of any survey line is not in such a
location that any cetacean is trapped by the vessel and the noise, for example in a
small harbour. In such an instance, the survey should start in such a place that any
cetacean in the vicinity has a clear and rapid means of escape into open water and
away from any unnatural noise source. Further details and advice can be obtained
from the following web site:-
http://www.jncc.gov.uk/pdf/Seismic_survey_guidelines_200404.pdf. This web site
refers to UK waters and relates to air guns as the sound source (in many ways different
to a sparker or boomer), but should serve as a useful guide nonetheless.

1.2. Introduction
The CSP-SNv is an evolution of the CSP-S range of seismic power supplies. The CSP-SNv
has a high voltage charger rated at 4000 joules per second (peak), and can supply up
to 1250 or 2400 joules of energy per shot into the seismic sound source, for example
Dura-Spark. The CSP-SNv incorporates microprocessor control and configuration for
greater configuration flexibility and reliability whilst retaining a fail-safe logic design.
The CSP-SNv is built on the proven high voltage technology of the industry leading CSP
range of power supplies adding to the standard safety systems and operational
functions found across the entire range of CSP energy sources.
The CSP-SNv is configured by an intuitive menu driven app, when operational the LCD
provides real time system status for operational safety and monitoring.
The CSP-SNv feature a selectable soft-start ‘power save’ setting; AVIP (Automatic
Variable Input Power) which allows the units to be operated from reduced generator
sizes when operating at low output powers. Traditional high voltage power supplies
(bang boxes) will charge the energy storage capacitors at a fixed high rate for example
at 4000J per second even when the average energy drawn from the capacitors is less;
a typical example may be 100J at 3 pps (300J). This results in a rapid capacitor charge
rate for <30mS followed by nothing, until the next discharge / charge cycle. This charge
/ no charge operation can often result in generator hunting as the load changes, and
may mean that a larger generator is needed than would be the case if the power
requirement was averaged over time. By reducing the peak charge rate, the generator
hunting is all but eliminated, and a smaller capacity generator is required. The AVIP will
automatically adjust charge rate from 20% to 95% of specification, thus lowering the
peak charge rate to just 300J / second compared to bursts of 4000J / second.
The CSP-SNv allows the user to effectively ‘tune’ the sound source to operate at a lower
frequency by lowering the operating voltage and increasing the capacitance to supply
the correct energy to the sound source. This may be effective in certain instances
where more penetration is required.
The CSP-SNv monitor the output of the system for open circuit fault conditions and over
current fault conditions, limited to approx. 10,000A.

1.3. Installation
Siting the CSP-SNv
The CSP-SNv delivers high energy, high voltage pulses, yet still emits minimal electrical
emissions, and so can carry the CE mark.
The CE marking ensure that the CSP-SNv 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. However it is often more convenient to locate
the CSP-SNv nearer to the back deck and the deployment area so that the high voltage
‘output’ cable run is minimised.
As high voltages are present, the CSP-SNv must be located away from water spray and
condensation, in an environment which is not allowed to become too hot. Care should
be taken to allow safe and easy access, and that high voltage cables are out of harm’s
way. It should also be possible to switch off the unit quickly without having to reach
over it!
Ventilation should also be present. All units draw air in from the rear and exhaust air
from the front. For operation in high ambient temperatures, the rear cover of the transit
case should be removed to allow a good air flow. If condensation is allowed to develop
serious damage may occur. Good room ventilation should be ensured, with no sudden
change in temperature (i.e. bringing the unit into a warm room from a cold area) and
allow the fans to operate for 10 - 15 minutes before switching on the high voltage.
The CSP-SNv Unit will normally be supplied from the factory in a ‘Hardigg’ transit case.
As is the case with all electronic equipment, care should be exercised in handling. For
maximum airflow in high ambient temperatures it is recommended that the anti-
vibration housing rear panel be removed. The CSP-SNv should be positioned on its
base in a dry ventilated area. Airflow for cooling is from back-to-front of the unit; there
must be at least 50-60mm clear room from the rear panel to any obstruction. If the
unit is to be operated in very warm ambient temperature (25°C or above), for optimum
performance an air conditioned environment is strongly advised. If the unit overheats,
it will switch OFF for a few minutes until it is cool.
Although the unit produces minimal interference, and carries a CE mark, it is often good
practice to put the CSP-SNv away from the navigation and survey equipment and
somewhere where cabling to the sound source can be run conveniently and safely. It is
this cabling which is the most common source of electrical interference.
