Quality control in the oil and gas industry is being advanced by

tool probes and calibration products from global leader Renishaw.

The company is playing a key role in the preventive maintenance

programme of Texas-based

FMC Technologies which has a manufacturing

base in Dunfermline, Scotland where it uses

Renishaw equipment to check and verify dimensional accuracy

of its CNC machine tools.

FMC develops and manufactures oil and gas

Production Control Systems (PCSs) which

consist of topside (surface) controls, power

equipment, the Subsea Control Module

(SCM), various sensors, and sub-sea electrical

and hydraulic distribution equipment. An SCM

contains electronics, instrumentation and

hydraulics for safe and efficient operation of

valves and chokes on the well-top 'subsea tree.'

Wells can be 120 km from the production platform, in water

up to 10,000 feet deep. So when

an SCM is installed on the seabed, it has to be

reliable and safe for the production life of the

well, which can be decades. If a critical part

malfunctions, the potential cost can run into

tens or even hundreds of million dollars.

FCM in Dunfermline has 20 CNC machine

tools, and a recent investment includes a £2.5

million, purpose-designed and built SCM

machining cell, with horizontal boring

machines loaded and managed by a Fastems

automation system.

This is used to machine the stainless steel

hydraulic manifold block, which is a critical

control element in an SCM assembly. The 267

kg block has a complex 350 drilled holes, and

the company makes more than 200 manifolds

a year when the cell is fully operational. If a

tool break occurs during operation, a

Renishaw NC4 laser-based tool setting system

will notify the Fastems system, which will reject

the pallet and replace with another.

To ensure accuracy each of the 20 machine

tools is serviced up to three times a year, with

each checked using a Renishaw ballbar. The

company has also invested in Renishaw's

CNC Reporter software - initially to keep production records

but also now in its maintenance operation.

FMC maintenance technicians Craig Simpson

and Mike West who are responsible for the

service and support of the 20 CNC machine

tools, said of the manufacturing process:

"Traceability is everything." The performance

standard is zero defects and "nothing leaves

the machine shop unless it is exactly right -

but we couldn't do it without Renishaw."

Record keeping and traceability are vital and

by using Renishaw products FCM can trace

back a finished or shipped part if any show a

fault and prove whether the machine was

accurate and aligned when the part was

manufactured.
