7 – Operating Procedure
DPN 402197 © TSS (International) Ltd Page 29 of 30
7.6 ROVS
You may use the 350 System with most types and size of ROV, and you may operate
it at depths down to its maximum specified depth rating. The standard installation
described in this Manual provides a high degree of accuracy and a useful measure-
ment range, together with ease of deployment.
It is important to install the 350 System properly by following the instructions included
throughout this Manual. The System will supply valid survey data only if you follow
these installation and operating instructions, which allow you to install the System on
most types of ROV.
7.6.1 Speed of Operation
The 350 System delivers measurements to a data logger continuously at a rate that
allows deployment on the faster ROVs. This is sufficient to maintain a high track reso-
lution under all normal operating conditions.
7.6.2 Altitude above the Seabed
The vertical detection range of the 350 System is limited by the frequency and magni-
tude of the target tone.
Where you will use the System to track a weak current at low frequency you should fly
the ROV as near to the seabed as possible, while avoiding damage, so that the coils
remain close to the target. If your ROV has an automatic facility for maintaining alti-
tude, you may use it.
7.6.3 Tracked ROV
You may install the 350 System on tracked ROVs. This type of ROV should allow you
to set a fixed coil height.
If you mount the System on an ROV of this type, locate the coils approximately one
metre above the seabed.
