INSTRUÇÕES PARA NAVIOS DE PESQUISA SÍSMICA
(INSTRUCTIONS FOR SEISMIC SURVEY VESSEL)

1.
The purpose of the present Instruction is to assure the safety of seismic operation inside Brazilian Search and Rescue (SAR) area for both
Seismic Survey Vessels (SSV) and other ships in the vicinity. Due to the risk of collision, Brazilian Navy must broadcast a Maritime Safety Information
Bulletin, named “Aviso aos Navegantes” (notice to mariners).

2.
Therefore, all SSV are required to daily transmit, during the survey, a type 2 message from SISTRAM, informing the working area for the
next six days. All your SISTRAM messages must contain the “Y” field filled. This field is used to provide information about the survey and
coordinates of your working areas, separated in four parts (Y-1, Y-2, Y-3 and Y-4).
Y-1 -
Working area for the first three days.
Y-2 -
Working area for the three days following Y-1.
Y-3 -
Working area (only used when the first working area is assigned for a period of 1 or 2 days)
Y-4 -
Vessel and towed array characteristics with the following information:
One – Hull color.
Two – Superstructure color.
Three – Medium speed during surveys;
Four – Towed array characteristics;
Five – Signals used (buoys, lights, etc);
Six – Other relevant information.
Considering all maritime traffic implications, the 3-days survey area shall be as small as possible.

3.
Examples on how to fill the “Y” field of a type 2 message from SISTRAM are shown below.
