Item Definition as used throughout this Manual
ALT Coil altitude above the seabed. This could be measured by a sub-sea altimeter con-
nected either directly to the SEP or through the umbilical to the SDC. Where there is no
altimeter fitted to the System, ALT could contain a fixed coil height that you specify dur-
ing the configuration procedure.
COV Target depth of cover. The SDC calculates this distance by using COV = VRT – ALT.
CV Composite Video. This can be utilised in either NTSC or PAL formats.
LAT Lateral offset. The horizontal distance measured by the 440 System between the top of
the target and the centre line of the coil array. Positive measurements indicate a target
to starboard of the centre line.
PSU Sub-sea power supply pod. The depth rated unit that accepts an electrical supply from
the ROV and produces the conditioned and stabilised DC supplies used by the SEP.
ROV Remotely operated vehicle. Any form of sub-sea or surface vehicle supporting the 440
System during survey operations.
SDC Surface display computer. The configuration, control and display computer supplied by
Teledyne TSS to operate the 440 System.
SEP Sub-seaelectronics pod.Thedepthrated unitthatperformsthe measurementoperation
on the target.
VRT Vertical range to target. The distance measured by the 440 System alonga line perpen-
dicular to the coil surface, between thecoil array and the closest point ofthe conductive
target.

DPN 402196 Issue 4.1 © Teledyne TSS 1-1
1 Introduction
The Teledyne TSS 440 Pipe and Cable Survey System provides a convenient and uncomplicated
method for performing accurate submarine surveys on a conductive target such as a cable or pipe. The
440 System represents a considerable advance over its predecessor, the 340, in that signal processing
routines are used which can discriminate between seawater and metallic targets which helps to
enhance the accuracy of the information gathered during a survey.
The burial state of the target has no effect on System operation. However, you should note the
following:
❐The special characteristics of 316 stainless steel do not allow the 440 System to detect this
material reliably.
❐Do not use the 440 System to survey targets buried beneath iron ore, which will mask signals
from the target.
The 440 System includes a display and control computer that you should install where you may see its
screen easily while you operate the ROV. The display includes information to help you guide the ROV
along the course of the target. With the introduction of the 440 Pipe and Cable Survey System,
Teledyne TSS have also introduced their new DeepView for Windows software, which makes
configuration and operation of the system easier under a familiar working environment. This runs on
the Surface Display Computer (SDC) and makes all acquired survey data available to view or report to
external data logging equipment.
The 440 System operates in real time and provides accurate measurements at a rate that allows
deployment on board faster ROVs. The measurement technology used by the System also allows it to
operate out of water with no degradation in performance, range or accuracy. You may therefore usethe
440 System for land-based or amphibious survey applications.
This System Manual contains full installation and operating instructions and is an important part of the
440 System. You should ensure the Manual remains easily available for use by those who will install,
operate and maintain the System.
Provided you follow the installation, operating and maintenance instructions included throughout this
Manual, the 440 System will maintain its specified measurement accuracy.
1.1 Migration from the 340 Cable and Pipe Survey System - Sum-
mary of Benefits
The Teledyne TSS 440 system represents a considerable improvement over the previous 340 system.
It operates to a greater target range than the previous system, yet is simpler to set up and operate.
The previous generation of products used a geometric algorithm to reject seawater which was based
on the assumption that the undesired seawater signal is the same across the three coils. The new 440
product has an advanced compensation method which exploits the different types of signals generated
by target and seawater. This allows the range to be determined from two search coils, giving up to a
50% improvement in range.Although the conductivity of seawater varies widely, the system can
accommodate all situations.
Extensive testing under a variety of water conditions shows that the characteristics for the local water
conditions need only be determined once per survey: the user simply inputs the approximate water
temperature. An automatic method to tune the system after deployment is provided, but need only be
used in exceptional circumstances.
