Abstract
There is a method for obtaining control of a source array configured to generate seismic waves. The method includes accessing an interface unit attached to a fixed structure that is substantially stationary in water, the interface unit being connected to a source array; entering a passcode to the interface unit to gain access to the source array; downloading a shooting sequence or a driving signal to a controller of the source array; and actuating the source array to generate seismic energy into water.

A method for obtaining control of a source array configured to generate seismic waves, the method comprising:
- accessing an interface unit attached to a fixed structure that is substantially stationary in water, the interface unit being connected to a source array;
- entering a passcode to the interface unit to gain access to the source array;
- downloading a shooting sequence or a driving signal to a controller of the source array;
- and
- actuating the source array to generate seismic energy into water.
A seismic acquisition system comprising:
- a marine source array configured to generate acoustic energy, the source array being in a locked mode;
- and
- an interface unit connected to the marine source array and configured to change the source array to an operational mode when a predetermined passcode is entered to the interface unit.
