Pigott Shaft Drilling Limited
is the leading specialist onshore mud cleaning equipment rental company
in the UK.
The founder and chief executive
of PSD is Colin Pigott B.Sc.(Eng.), C.Eng., F.I.C.E. He
is very well known and respected within the civil engineering and drilling
industries, having spent over 30 years in the management of piling and
groundworks projects. He designed and built the TITAN reverse circulation
rig, which could drill blind shafts of up to 4m diameter to depths of
over 300m. He also developed and supervised the innovative rock
roller bit techniques that were used to excavate the central piers of
the Thames Barrier, thereby saving many months on the construction time
for that project.
The wide knowledge of drilling
systems and drilling muds gained by PSD has been used in the creation
of their extensive range of high performance mud cleaning equipment which
is available for hire for use in civil engineering applications throughout
the world, with or without operators.
We are renowned for high
quality mud cleaning and specialise in ‘dry discharge’ solids separation
with flowrates of 10 to 1200m3/hr.
We work mainly in Europe,
but are often taken further afield such as Hong Kong, Africa, the Middle
East and South America by our existing clients or their associated companies.

PSD has for over 15 years been supplying
rental mud cleaning equipment and mud services to the civil engineering and
drilling industries. We have experience of cleaning mud on hundreds of
directionally drilled crossings including the largest diameter crossings in
Europe. We have also worked on hundreds of pipejacking and micro-tunnelling
projects through many different types of ground. In addition we have
cleaned mud for many diaphragm walling projects with grabs and hydraulic cutters
as well as carrying out work for many other applications.
Our management personnel have experience
of earth
moving, trenching, bored & driven piling, diaphragm walling, rock drilling,
coring, large diameter shaft drilling by forward & reverse circulation,
tunnelling, pipe-jacking, micro tunnelling, caisson sinking, horizontal
directional drilling, off-shore & on-shore oil & gas exploration &
production, oilfield waste slurrification & reinjection into deep strata,
canal & dock cleaning, soil washing, quarrying and also minerals recovery.
They have been directly involved with such prestige projects as the Thames
Barrier, London Water Ring Main and the Channel Tunnel Rail Link, as well as on
smaller projects such as gas pipelines, sewers and bridge foundations.
The
majority of PSD’s machines are designed in-house and built using high quality
materials and components. Our plants are designed to be easy to transport,
set up and to operate, The machines are built specifically for the rental
market where reliability is of great importance, yet where operating costs need
to be low. The design principles that we employ for our equipment mean
that they achieve the optimum performance from the components used and that
each machine will provide better performance than similar sized or rated machines
available elsewhere on the European rental market.
Our policy of environmental
awareness and continuous improvement using input from clients, plant operators,
designers and equipment manufacturers ensures that our machines are at the
forefront of technology and performance and are easy to operate and maintain.
As an example, the creation by
PSD of a new class of high volume ‘SS’ desander, coupled with the use of
very efficient ‘SU’ desilters, has revolutionised mud cleaning, making
on-line cleaning a reality and reducing or eliminating the need for large volume
mud storage pits.
Another major advance that we have made
in recent years is the use of a computerised 3D design package
for our new machinery and equipment upgrades. Every component is modelled
and accurately positioned in 3D space so that a virtual reality model is created. When this is complete two dimensional drawings
are produced
and used for the fabrication of the equipment. The precision of the 3D
design coupled with accurate fabrication enabled the 152DP centrifuge to be
constructed so that the centrifuge module could be stored inside its tank with
only millimetres to spare.
We are frequently appointed to work in support of
clients on very challenging and critical jobs and our clients place great trust and confidence in our ability to provide the enhanced and
cutting edge performance that they require for these important projects.
Our "can do" approach enables us
to meet the high expectations of our clients and often enables us to apply
our wide knowledge base to new and interesting applications.
We constantly seek to provide even better
products and services so as to further extend our lead over the
competition and thereby increase, for our clients, the benefits of employing
PSD.
In short, we are committed to
providing to our clients a high standard of service at an affordable price.
