Safety
WARNING: Trapped air requires considerable time to compress and
when it is compressed is highly dangerous. It has enough stored
energy to separate parts with considerable force.
Seals in high-pressure vessels are also susceptible to explosive
decompression; the O-rings or rubber gaskets used to seal pressurised
pipelines tend to become saturated with high-pressure gases. If the
pressure inside the vessel is suddenly released, then the gases within
the rubber gasket may expand violently, causing blistering or explosion
of the material.
All pressure equipment has a particular pressure rating and care must be
taken to ensure that no item is used in a situation that may cause its working
pressure to be exceeded.
All personnel involved in pressure testing must be formally trained, competent
and utilising the appropriate PPE.
Safe-Lok devices, where fitted, should be checked for positional security to
avoid unnecessary movement of the collar
Ensure the identification band/plate is fitted and is displaying the correct
information as per the Tag Sheet/Index
This equipment and the equipment it is attached to is heavy never position
yourself below a suspended load

1 Introduction
1.1 General
The IRIS tool catcher dispenses with the traditional collet style grapples,
which are restricted in the range of fishing necks that can be caught, and
instead introduces a unique array of shaped fingers that form a spring loaded
iris that automatically adapts to suit any size of fishing neck.
This user manual serves as an introduction to the equipment and contains the
relevant specifications, operation, planning and maintenance instructions,
parts list and drawings.
1.2 Product Identification
Phuel products are identified by a unique serial number that facilitates full
product traceability. Each product is supplied with a documentation pack that
contains product certification and material/inspection reports. The serial
number is always etched on the surface of the product but can sometimes be
difficult to find or read after painting. A customer identification number is also
included to allow the customer to track the asset in their system.
A stainless steel band secures the nameplate tag that is stamped with the
information shown below. This tag should be located in the first instance to
ensure that this manual refers to the correct equipment.

2.1 Fishing Neck Limitations
Fishing necks generally conform to an unofficial industry standard, but there
are some products on the market that fail to comply. The fishing neck head
length (Z) should therefore be measured to confirm that it will fit inside the gap
between the two sets of finger rings. If the head length (Z) is larger then it will
be necessary to remove the upper set of fingers and replace it with the Spacer
Ring, bought seperately (see Section 8.1.2)

3 Technical Description
3.1 Description
The IRIS Tool Catcher is designed to prevent tool strings from falling
downhole in the event of a breakage in the wire after the rope socket has
struck the stuffing box. The unique IRIS fingers will catch in the recess of the
fishing neck and lock the tool string in position. The Tool string can be
released by applying hydraulic pressure to the piston to open the fingers –
note that this will occur even with significant tool string weight so operators
must guard against the dropping of the string when hydraulic pressure is
applied.
There are twelve independent fingers mounted on a pivot joint that are spring
closed. The upward movement of the tool string will naturally open the fingers
against the spring, and they will then collapse into the recess below the fishing
neck. When the tool direction is reversed the sharp angle at the base of the
fishing neck prevents the fingers from opening allowing the whole tool string
weight to be supported.
There is a second set of IRIS fingers mounted in the reverse direction and the
top of the tool catcher. This group acts as a stop for the tool string to ensure
that the lower set of fingers is correctly positioned to catch the fishing neck
upset. The upper set is also mounted on a shock absorber so that any upward
momentum is dissipated with minimum shock loading to the wire and the tool
string. The fact that we are using IRIS fingers as an upward stop has the
additional benefit that the tool string can now be loaded through the tool
catcher from the top, which greatly simplifies the set up operation. Note that
the tool string cannot be withdrawn from the top unless the top set of fingers
are being held open with a suitable, locally manufactured, tubular sleeve (not
supplied).
The Tool catcher is moved into the release position by applying hydraulic
pressure to the piston, which will move upwards and force the fingers into the
open position. With the piston fully extended the fingers are open to allow full
bore access to the tool string.
Note: The second set of iris fingers can be removed and replaced with a
spacer ring (supplied) if a longer fish neck is to be used. Care must be taken
that the fingers can only catch in the correct recess when the tool strings
stops and the top of the riser.

3.2 Tool String Insertion
Ensue tool catcher set up for
correct length of fish neck
Visually check both sets of
fingers are closed
Attach hydraulic hand pump to
½’’ NPT fitting and apply
pressure to open the bottom
set of fingers
Insert tool string allowing it to
pass through both sets of
fingers
Release pressure allowing the
fingers to close
Remove hand pump

3.3 Withdrawal of Tool String (Catching)
Tool string withdrawn from well
As tool approaches iris fingers they
automatically open allowing tool to
pass
Once wider part of tool passes
through iris the fingers close to the
size of the tool neck
Upper set of fingers act as a buffer to
prevent tool from being totally
withdrawn from the catcher
With tension released on the tool
string the tool drops and rests on the
iris fingers
Note: if a longer fish neck is used the upper set of fingers are not fitted and
therefore the tool can be withdrawn from the top catcher when rigging down.

3.4 Long Fishing Neck Configuration
The Tool Catcher can be configured for long fishing necks by removing the
upper finger set. Follow this procedure to re-configure the assembly for this
purpose
Split the top and bottom sub connection and remove the top sub
Remove the spacer spring, finger assembly and shock absorber from
the top sub
Fit the spacer ring at the bottom of the top sub bore then the spacer
spring
Ensure that the finger seal sub is still fully made up to the bottom sub
as this connection may have backed off when removing the top sub
Verify that the ‘O’ ring is still in good condition – replace if required
Make up the top sub again taking care not to dislodge the parts inside it
Feel from the top end that the parts inside are held together correctly
Open and close the fingers to ensure that they are operating correctly
Note – When ever the top sub is removed check
that the seal sub has not backed off before re-
assembling.

4 Operation
All operations to be carried out by suitably qualified and competent personnel
4.1 Setting Up
Position the tool catcher at the top of the riser stack immediately below
the stuffing box, grease head or Turnaround Sheave (see note below)
Remove protector to allow fitment of ½” NPT connector
Attach a hydraulic hose to the ½” NPT port using a suitable adapter –
secure the hose to the riser to prevent trapping when lifting
Refit protector
Apply pressure to the tool catcher to open the fingers. If possible look
in the bore to confirm that the fingers are opening. Bleed off and
confirm that they are closing again fully.
Make up the rest of the riser stack as normal
4.2 Inserting the Tool String
Apply pressure to the port to open the fingers and insert the tool string
– remember it will not be possible to withdraw the tool string again as
the upper fingers will catch in the recesses between the tool sections*.
When the rope socket (or cable head) is reached, push it beyond the
lower finger set and then bleed off the hydraulic pressure to release the
fingers. Pull the string back against the upper finger set to lock the rope
socket in the catcher.
*Alternatively the string can be inserted from below the catcher by
feeding only the cable head through the catcher then making up the
string to the cable head and then pulling back into the catcher. Either
method is acceptable
4.3 Operating (Catching)
The Catcher is automatically set at ready to catch if no pressure is
applied to the hydraulic port and there is no fishing neck in the Catcher.
Pull the tool string upwards until the rope socket tags against the top
set of fingers and the slack off the weight and the fingers will now
support the tool string
4.4 Operating (Releasing)
Take the weight of the tool string and lift up until the rope socket tags
the upper set of fingers

User Manual
Tool Catcher
OPS-4428 Rev A 9
Apply pressure to the tool catcher to open the fingers
Slowly lower the tool string to make sure that the fingers have fully
retracted and have cleared the tool string
Bleed off the pressure to set the catcher ready to catch again.
4.5 Pre Job
