1. Introduction
The Vigo profiling winch (hereafter referred to as ‘the winch’) simplifies the task of repeatedly
deploying a sound velocity profiler or other instrument (hereafter referred to for simplicity as ‘the
profiler’), either from a moving or stationary vessel, eliminating the need for an operator to manually
collect profiles from the rear deck. It can also be configured for use from unmanned surface vessels
(USV’s).
The system is designed to operate primarily with a Valeport SWiFT SVP, with an option to use a Rapid
SV profiler for deeper water work. Both these profilers feature Bluetooth® data transmission, allowing
automatic retrieval of the recorded profile.
The winch control software allows profiles to be collected manually, when required, or automatically
based on distance or time interval. It is a self-contained system, requiring only single phase 230v
power, and a wired ethernet connection to operate.
The winch incorporates several features designed to make its installation easier and its operation
simpler and more reliable. These features include:-
a) Integrated control and operation software that runs on the winch and is accessed through a
web browser.
b) Built-in GPS receiver.
c) A boom carrying the line sheave that can be extended over the stern for deployment of the
profiler, or retracted for access to the sheave and profiler on completion of the series of casts;
no swiveling platform is needed.
d) A line-limit tube and switch mechanism to alert the operating software that the profiler is very
close to the line sheave.
e) Audible and visual warnings prior to any automatic movement of the winch.
2. Summary of Warnings
The warnings summarised below are intended to prevent injury to personnel and damage to
equipment in what can be a hazardous environment.

3. Installation
3.1 Location
The winch should be mounted at a location which allows the boom to be extended over the stern, far
enough from the vessel outline that the profiler is unlikely to contact the hull.
Apart from its location the height of the mounting platform should be such that when the profiler has
been fully recovered it will be suspended clear, or partially clear, of the water and in a position where it
can reliably transmit data.
If a raised platform is needed this can be a simple wooden structure. The boom should be parallel to
the boat's centreline so that it will experience minimum sideways force when the profiler is deployed
and the boat is underway.
The winch is supplied with eight points at which attachment screws can be fitted. However it can be
secured with as few as six screws if necessary, leaving two of the holes empty.
3.2 Extending and Retracting the Boom
The winch is supplied originally with the boom in the retracted position; a configuration that it will
usually be returned to when not in use.
To extend the boom, release the red latch. This latch pivots on one of the top hinges of the boom, and
when closed, extends outwards to grip one of the other hinges. With the latch lifted pull the end of the
boom outwards until it locks in position. The mechanism that locks the boom reports the fact to the
winch computer which, if powered, switches on the two white LED’s that illuminate the boom area.
This extended position is necessary (in a normal installation) before the computer will allow casts to
be performed, and is confirmed to the operator via the control software.
To retract the boom from the fully extended position, lift the red knob on the levelwind unit. Whilst this
knob is held raised the boom lock is released and the boom can be retracted. Ensure that the rotating
red latch is above the path of the retracting boom then push the boom back fully towards the winch.
When the boom is fully retracted rotate the latch down to secure it.

3.3 Fitting the line to the level-wind
As supplied from the factory, the line is installed into the level-wind wiper arm between the clevis pin
and the removable drop-nose pin, as shown in the illustration below. Should the line need to be
re-fitted it is a simple matter to remove the drop-nose pin, threading the line between the guides and
refitting the pin. Ensure that the toggle on the end of the drop-nose pin is closed fully.

3.4 The Line-Limit Tube
The winch is supplied with a line-limit tube fitted to the line. This item is vital for the correct operation
of the winch.
The sheave assembly mounted at the end of the extending boom incorporates both the main pulley
and, above the line, a smaller wheel. This upper wheel detects when the line-limit tube enters the
sheave assembly and triggers a switch which has two functions, as follows:-
1. It tells the winch to stop pulling the line in, preventing the profiler from impacting the sheave
assembly
2. When performing the pre-launch configuration it enables the winch to position the profiler
automatically a certain distance from the sheave assembly (see section 4.5).
The line-limit tube consists primarily of a flexible tube, one that engages with the upper wheel to rotate
it but without applying excessive force to the sheave assembly. In normal operation, because the
recovered line cannot stop instantly, the tube is carried a little distance through the sheave assembly.
The tube is fitted to the line immediately above the line’s suspension loop, the loop that carries the
profiler’s attachment shackle. In this position it typically stops the line recovery with the shackle 65mm
above the plane of the winch’s mounting platform. If the boat’s freeboard is such that this does not
allow reliable communications then the platform may need to be raised, as already mentioned.

Removing and replacing the line-limit tube
It is strongly recommended that only genuine C-MAX line-limit tubes are used. Silicone tube is
available in various diameters, thicknesses and grades, and a repair or a substitute may not work as
intended. An unreliable limiting action could result in equipment damage.
To remove the tube, first slacken the gland nut and extract the tapered grommet which it has been
gripping. Pull the grommet off the end of the line past the suspension loop in the line where the
shackle is normally attached. Follow this by removing the gland and tube via the same route.
8

Fitting the replacement tube is the reverse of the removal process. With the new tube in place over
the line follow that with the tapered grommet, tapered end first. Getting the grommet over the
suspension loop can be made easier by passing a light line (eg. cotton thread) through the grommet,
through the line's loop then back through the grommet: this enables the bulky loop to be pulled
through the grommet.
With the grommet just clear of the line's loop advance the tube’s gland over it and tighten. Whilst
tightening the gland continue to press the grommet into it.
3.5 Power Supply
The winch is supplied with a 10m power cable. The power cable should be routed safely to a suitable
230v single phase source and terminated either directly into a switched disconnect or in a suitable
plug. The cable should be protected with a 6 amp fuse or circuit breaker. For operator safety ensure
that all applicable requirements for neutral-earth bonding have been followed when installing the
power cable.
The power connector on the winch has a bayonet locking ring which should be fully rotated to lock the
connector into place and to ensure a watertight seal. Avoid forceful insertion of the power connector
into the receptacle; this can easily damage the plastic bayonet latches on the locking ring.
Conductor colours used in the supplied power cable
The winch will monitor the voltage of the AC supply every second to ensure it is within the range
200-255v. If the supply exceeds these values, a warning will be displayed to the user. If this warning
appears, the user should power down the system and rectify the voltage supply issue before
restarting the system.

3.6 Network
The winch is controlled through a web application and to facilitate this a connection to the survey
network is required. A 10m ethernet cable is supplied with the winch as standard. The cable has a
waterproof RJ45 connector on one end that locks onto the corresponding LAN connection on the
left-hand cover of the winch.
Connecting the waterproof RJ45 connector
The ethernet cable should be routed safely to a suitable network switch in the survey room.
NOTE: If the cable needs to be passed through a gland or bulkhead penetration, the dry end RJ45
connector can be removed and subsequently replaced with a standard RJ45 crimp connector using
the EIA-568B wiring colours:
RJ45 wiring to the EIA-568B standard
Do not remove the waterproof RJ45 connector from the cable under any circumstances.
