1 GENERAL INFORMATION
This manual is a user manual for the Subsea Claw Cutter tool.
The Subsea Saw has a rotating blade which is 600 mm in diameter. It is built to be used with a
Subsea ROV, controlled by manipulator and hydraulic supply from the ROV to drive the saw.
It is designed to cut steel pipes/profiles, armored cable and flexirisers. Standard blades to be
supplied with the saw are carbide and diamond types. The saw has claws to hold on to the object
which is being cut. Claws can be replaced if specific interface is required.

3 SAFETY
3.1 General –Operations
Only authorised people and qualified personnel should work on the system, and take suitable
precautions to prevent any potential injuries. Always adhere to authorised working practices, and
use the correct tools for the job. To facilitate this, make sure that these are available before
commencing the test.
Ensure that the working area is kept clear and uncluttered.
3.2 General –Hydraulic
Do not work on pressurised systems. Hydraulic systems contain a large amount of stored energy
when pressurised, therefore the system (including any accumulators) should be de-pressurised,
and the power pack switched off, prior to working on the system. Exceptions to this would be
system adjustments to components requiring the presence of pressure and/or flow.
Any personnel authorised to work on the system must have a complete understanding of the
operation of the hydraulic system, so that they will be aware of any system liable to remain
pressurised or hazardous in any other way. Ensure that all personnel are clear of any
mechanical/hydraulic system likely to move if pressure to system actuators is released or applied.
Do not attempt to tighten any leaking fittings whilst under pressure. A hose/fitting rupture could
result, leading to injury from flying components and/or oil jets.
Regularly inspect fittings and pipe-work for mechanical damage. If any such damage is found, the
item must be repaired or replaced as necessary before pressure is applied to the system. Do not
allow damaged fittings to remain in service.
Take care when inspecting, commissioning, repairing or maintaining the system to avoid jets of oil
issuing from open orifices; pipe ends etc. if pressure is applied. Particular care should be taken to
protect the eyes.
Hydraulic components may be heavy and slippery when covered in oil. Ensure that adequate
protective clothing and footwear is used.
Any moving component should be treated with caution when the system is pressurised during
operation, and especially during on-deck testing and repair. Keep clear of all moving components,
and take all necessary precautions to avoid injury when working on these systems by preventing
movement of any components likely to cause injury.
3.3 General –Mechanical
Beware of and keep clear of all moving components. Do not work on the system whilst power is
applied, or if there is any potential for components to move.
Ensure that all load bearing components are adequately and regularly inspected. If damage is
found the component must be repaired/replaced as necessary. Do not allow damaged
components to remain in service.

Always ensure that items are correctly and adequately supported before removal, and that
authorised lifting equipment and procedures are used.
Note: trying to lift heavy components in an awkward position by hand without the assistance of
correct lifting equipment, or lifting any component without adopting the correct stance, can lead to
serious injury.
Ensure that when working within or underneath the machine that your presence is known to your
supervisor. If working underneath the machine, always ensure that there are no loose or
unsupported assemblies, components or tools above.

4 OPERATIONAL DESCRIPTION
The following description is a generic description of preparation and use of the Subsea Claw
Cutter. Customers are advised to adapt the following information to their own specific operations
and specific work area.
4.1 Transportation
Make sure that the saw is properly strapped in the transport box, example of how to do this is
shown in the pictures below:
4.2 Preparation on the vessel prior to operations
➢Unpack all parts and check for transport damages
➢Verify that all parts on equipment list is present
➢Check the cutting blade for damage.

➢Check that the blade is installed correctly, not loose and correct direction.
➢Check all hoses and fittings for damage and leaks.
➢Check that all bolts are in place and tight.
➢Connect the hydraulic hoses to the ROV corresponding hydraulic system.
➢Ensure that the piston on the feed cylinder is fully retracted.
Function test:
➢Do not start the saw on deck without securing the area.
➢Run the clamp cylinders to full stroke.
➢Time the motor feed rate.
➢If the motor feed rate is to fast/slow, adjust it using the feed flow regulator and try again.
(This is also dependent on the ROV flow and pressure).
4.3 Feed flow regulator
Adjustment flow wheel:
Locking wheel:
➢The regulator is located on the right hand side, it can be seen in the drawing in Appendix A
sheet 2 (item 23 on part list).
➢The regulator can be adjusted to change the feed rate.
➢Start by loosening the locking wheel CCW while holding the adjustment flow wheel from
turning.
➢Adjust the flow wheel in small increments.
➢Apply adequate lubrication to thread and spring washer. Recommended lubrication: Aqua
lube/aqua shield.
➢Make sure spring washer is in place before tightening together again.
4.4 Subsea use
➢Ensure all the checks and preparations have been performed.
➢Ensure the saw is securely fastened to the ROV using the designated ROV handles.
➢OR it is securely connected to a crane.
➢Lower the saw into position.

➢Run the clamp Actuators to lock it around the area of object to be cut. (Ensure it is securely
fastened)
➢Run the saw, this will cause the feed cylinder to activate.
➢Perform the cut.
➢When the cut is finished retract the saw blade.
➢Retract the cylinders for the clamp.
➢Return to deck and perform “After operations maintenance”, ref chapter 5.

5 MAINTENANCE
Repair and maintenance work on the saw shall only be performed by qualified personnel,
specifically trained on this equipment.
5.1 After operations
➢Plug hydraulic hoses to prevent hydraulic leaks and dirt to enter the hydraulic system.
➢Clean the tool with fresh water. Apply an anti-corrosive layer on the tool when it is clean,
WD40 or similar.
➢Check hydraulic hoses, bolts, etc.
➢Check the cutting blade for damage.
➢When stored make sure the cylinders is fully retracted, to avoid corrosion.
➢Place tool in its original transport case/storage box and secure with straps.
5.2 Periodic maintenance
➢Start with “After operations” maintenance procedure.
➢A careful review of the entire tool is mandatory. This includes a visual check of the tool with
hoses and a function test. Be sure that there is no leaks and that the feeding rate is correct.
➢Replace or fix parts if needed. Damaged paint must be repainted.
