2. Industry Leading Solutions
WLSL Industrial Measurement:
Distinguished by our depth and breadth of industry knowledge
developed from undertaking numerous projects, Warner
Industrial Measurement brings the accumulated intellectual
capital that enables our teams to assess information and
quickly advise project stakeholders of the impact of technical
issues. A key part of this skill is the capability to communicate
the findings in a simple and concise manner. Vast experience
in the process industries has allowed WLSL to develop unique
methodologies which means we provide solutions that are
subject to rigorous analysis to ensure that we meet the client’s
budget, time and operational constraints.
Dimensional Control Methodology Summary:
WLSL uses the most up to date Sokkia MONMOS coordinate system (Net1200 plus 3-DIM Controller Software). This
equipment is a first-order three dimensional measurement system which allows operators to calculate precision
coordinates and elevations in real time. The dimensional accuracy of the instrumentation is 1” vertical collimation
accuracy, 1” horizontal angle accuracy and 0.8mm +2ppm @150m distance accuracy. We can therefore report
spatial dimensions to 1mm accuracy.
WLSL will first establish a local network of control points surrounding the unit to be surveyed. We will then work from
these control points to locate all details and features to a positional accuracy of 1mm using auditable measurement
techniques. To reach the required accuracies for precision survey WLSL methods involve temporarily positioning
reflective targets in the vicinity of the areas of interest. These measurements can be applied to position, in real-time,
any object inside the controlled space or monitor movement.
High-Order Laser Scanning Methodology Summary:
WLSL uses Leica dual-axis compensated time of flight laser surveying instrumentation to capture fit for purpose data
sets and digital images. Our scanning methodology avoids the use of point-to-point registrations and will rely on
coincident and geo-referenced target registration. The control network is created using the industrial measurement
techniques described above and supported by conventional surveying methods from the whole to the part. This
methodology allows WLSL to capture data project-wide at the upper limit of the laser scanner precision capabilities,
which has a single measurement positional precision of 6mm, while maintaining an over-all data accuracy of 1mm.
At the same time the scanning is occurring, an
industrial surveying instrument is set up nearby by
another operator. The backbone of the surveying
process is the location of a network of 1mm accurate
scanning targets throughout the area to be scanned as
mentioned above. This surveying accuracy allows us
to rely on geo-referenced targets to register multiple
point-clouds with auditable surveying closure that
eliminates cumulative errors.
No job or client is alike:
For your next project, we will be happy to assess your requirements and provide a full and detailed methodology fit for
purpose for your needs.

4. PROJECT EXAMPLE – TURNAROUND SERVICES
Project Statistics:
Client: Chevron
Site Attendance: 5 weeks
Safety: 100%
OVERALL PROJECT
This was a major turnaround project which
involved the refit of vessels in the FCCU
complete with exchanger change-outs, riser
replacements, man-way installations, and vessel
penetrations, among many other detailed tasks.
Some of the key jobs are outlined below, along
with examples showing survey reports.
RISER REPLACEMENT
For this critical component, WLSL completed
precise measurements for verticality, bolt
orientation, fabrication, weld-preps, and landing
position.
MANYWAY REPLACEMENT
A last minute addition to the scope of works,
there was no design information to this many-
way which had been a field change during a
previous turnaround. WLSL provided critical
geometry and set-out, as well as fabrication
checks, to ensure a first time fit.
EXCHANGER SURVEYS
WLSL first verified the removed bundles against
the newly fabricated bundles. After surveying
the interior of the shell, it was found that
deformation around the nozzles had occurred
and this would not allow the new bundle to enter
smoothly because of a design change. WLSL
provided data so the bundles could be modified
by 3mm to ensure a smooth fit.
RESULT
WLSL helped save time during the turnaround
by providing critical geometry information to high
accuracy, enabling the engineers to make the
right modifications before the new kit was
offered into place.

6. PROJECT EXAMPLE - REGENERATOR SURVEYS
Project Statistics:
Client: Statoil
Site attendance: 3 weeks
Safety: 100%
OVERALL PROJECT
The project involved the installation of a major new
regenerator, associated infrastructure, and
additional piping. Critical dimensions needed to be
ascertained for proposed cut-lines, manufacturing of
new Overhead Line and analysis of regenerator
cone section.
OVALITY
In the top example, the existing weld and reference
lines at the proposed cut were surveyed using our
precision survey methods. The report shown is the
existing condition ovality that must be matched
correctly by the new fabrication of the regenerator
ahead.
EXISTING CONE
The same methods were used to precisely survey
and then model the existing cone section of the
regenerator as shown in the second example. This
report details the existing condition of the complex
shape.
OVERALL EXISTING CONDITION
To avoid clash and provide complete tie-in data for
the surrounding pipe-work, very accurate 3D ‘As
Built Data’ of existing plant were supplied. This
enabled clash free design of all integral components.
RESULT
WLSL have provided an integrated solution to the
above problem by combining; high accuracy
dimensional control, First Time Fit Critical
Interface & Overall plant modelling.

9. TYPICAL EXAMPLES
MONITORING, ALIGNMENT and DIMENSIONAL SERVICES
The following examples show some of the complex situations
where WLSL have provided key real-world geometry for design.
MONITORING
Monitoring of operational plant over set periods can provide
engineers with a real world glimpse of the dynamics occurring on
site. In the example shown, WLSL has monitored PRT at all
significant movement points for a number of years. This process
can also be extended to gantry cranes, vessel deformation, and
operational changes, even in real-time
EXISTING CONDITION
In many cases, plant has been fit-to purpose using field welds and no as-built information is available. In today’s world
of material upgrades, fabrication must be done off-site. WLSL can bring the geometry back to the engineer from any
location, including this wye piece cross-over in the FCCU.
ROTARY KILN ALIGNMENT
Machine alignment of rotary kilns represents one of the most difficult challenges in geometry verification. WLSL has a
history of providing this critical geometry for alignment. The kilns we monitor in the UK are described as “dialled-in” with
fewer hot-spots and less maintenance as all others in operation by our clients.
RESULTS
WLSL can provide a dimensional solution for nearly any complex geometry found in the refinery environment. More
importantly, our experience allows us to ensure that the reports are fit-to-purpose and the accuracy is acceptable for
design and fabrication.

10. PROJECT EXAMPLE – DIMENSIONAL CONTROL
RELIANCE JAMNAGAR
The Reliance Jamnagar Refinery has:
 The world’s largest FCCU
 The world’s largest Coker
 The world’s largest Aromatis complex
 India’s largest Sulphur Recovery complex
 India’s largest Petroleum Terminal
Warner Land Surveys Ltd were
commissioned to control the fabrication
& installation of the highly complex
“Cone to Cone” critical interface on the
existing Reactor.
The new cone standpipe was surveyed
in the fabrication shop in South Korea.
The exact shape of the “as built” new cone
section was set out to 1mm accuracy on the
existing reactor cone section.
The cut was carried out in accordance with
Warner Land Surveys cut lines and the new
cone section was installed. This was achieved
on a “First time lift and fit basis”.

11. PROJECT EXAMPLE – DIMENSIONAL CONTROL
BAPCO - BAHRAIN
Time required to achieve critical interface
fit-up between new plenum and existing head:
Without WLSL dimensional control = 14 Shifts
With WLSL dimensional control = 2 Shifts
WLSL’s contribution has helped to move
the plant restart date for this turnaround
further forward by days against the
anticipated programme for this event.
“We could not have done it
without you..”
Barry Ward, Project Manager BAPCO.
Return on investment: Cost for WLSL
services for the entire project was
approximately 85,000 Dinars.
Project completed on-time, in budget,
and with 100% safety.
Existing Regenerator roof precision measured.
New plenum precision measured
The two were then modelled to establish
the required fit-up.
The complex shape for the cut was then
set-out and made in the lay-down yard.
BENEFITS of WLSL SURVEY
Reduced shutdown time, Avoidance of re-work,
Improved process performance, Improved plant longevity
New Plenum to existing head - Cut line profile

13. PROJECT EXAMPLE – LASER SCANNING
& DIMENSIONAL CONTROL
HO-PING POWER STATION, TAIWAN
Existing condition survey of four classifier
units providing a complete ‘as-constructed’
solution.
Prior to WLSL involvement, dimensions were
collected by hand.
With WLSL methodology a rigorous data set
was supplied in a fraction of the time.
WLSL’s contribution has helped Loesche
Energy to develop a global standard on the
services they offer.
Each of the four classifier units were laser
scanned along with the site environment
during operation to enable clash-checking
of the new design.
In conjunction with the laser scanning, high
order dimensional surveys were carried out
on critical interface points for positional
reference, orientation and tilt.
Deliverables:
A complete environment 3D model created
from scan data, with interfaces modelled and
confirmed from dimensional survey.
Dimensional ‘fit-up’ reports in plan and profile
for each unit from the precise survey.
In addition, the point-cloud data was made
available to Loesche Energy using web-
enabled free viewer software for assessment.
BENEFITS of WLSL SURVEY
 Reduced shutdown time
 Avoidance of re-work,
 Improved process performance
 Improved plant longevity

14. RATCLIFF POWER STATION, UK
A survey was required of the boiler dead
space above the boiler while the unit was
shut down. A 3D model was created for
later use to assist with design and replace-
ment works.
It took 4 days on site using a Leica Phased
base scanner, completing 160 scans to
capture the required area.
PROJECT EXAMPLE – LASER SCANNING
Leica Tru-View:
Leica Tru-views were provided as an easy ref-
erence tool to view the data.
In addition, the point-cloud data was made
available to the end client using free viewer
software for their own assessment.
Deliverables:
A complete environment 3D model created
from scan data, with all interfaces modelled.
The model consisted of 36500 individual ele-
ments.

15. High Order Laser Scanning
Warner Land Surveys Limited has significant experience in providing clients with end to end as-built data solutions.
We can provide as-built data that enables clients and contractors to study, plan, and design for retrofits, expansions,
and refurbishments without necessarily needing to visit the site.
Besides accurate geometry models we can also provide data directly into any AutoCAD or MicroStation based system
without the need for purchasing new and expensive software. Intelligence can be achieved in a number of ways
including the use of our in-house expertise to mine intelligence from associated P&IDs or legacy design drawings.
We have a lengthy history, as well as an excellent safety track record, of using this system in on-site petrochemical
environments.
OBJECTIVES

work

16. Data Capture and Modelling – Laser Scanning
Detailed Discussion and Examples
Warner Land Surveys Limited (WLSL) has completed a significant number of successful projects for global clients
where we provided a fast, precise, accurate, and reliable method of creating large scale 3D Laser Scan data sets.
Furthermore, we have done so in a cost-effective and safe manner which resulted in industry leading fit-for-purpose
deliverables.
Through careful study and experimentation we have developed a scanning methodology that addresses key challenges in
the refining industry. WLSL has a lengthy history, as well as a perfect safety track record, of using this system on-site in
petrochemical environments.
METHODS
Warner Land Surveys Limited uses a range of
techniques and a wealth of industrial surveying
experience to ensure that the highest overall
dimensional accuracy possible can be achieved
using laser scanning. Each scanner on today’s
market can produce a very precise scan from
one position. The difficulty to ensure proper fit-
up of piping and steel, however, involves
ensuring accurate measurements across
multiple scans.
The backbone of our high-order laser scanning for process plant is to create a network of 1mm accurate positions
throughout the units to be surveyed. This network is created using industrial precise measurement techniques and is
supported by conventional surveying methods. This methodology allows WLSL to capture data project-wide at the upper
limit of the laser scanner precision capabilities, which has a single measurement positional precision of 6mm, while
maintaining an over-all data accuracy of 1mm.
Our methodology and product has been audited by clients and end users and found to meet the highest possible
tolerances for this type of measurement. In addition, we have provided clients with audits of other laser scan and been
there to pick up the pieces when they have been wrong. Without proper surveying techniques implemented on every
scan, surveying accuracy cannot be certified and our methodology directly addresses this reality.
INSTRUMENTATION
The precise network is accomplished by utilising a first-order three
dimensional measurement system. The dimensional accuracy of the
instrumentation used for this task is 1” vertical collimation accuracy,
1” horizontal angle accuracy and 0.8mm +2ppm @150m distance
accuracy providing 1mm positional accuracy over-all. We also use
more traditional 3” surveying instruments and prism kits in a
supporting role for verification of site control across multiple blocks to
increase base-line length and confirm site-control accuracy. This
traditional traverse may also be verified using GPS techniques and
precise levelling.
For laser scanning our principal equipment for conventionally laid out
units and pipe racks is the Leica C10 HDs Laser scanner. For the
more dense sections of plant which cannot be captured using ToF
(Time of Flight) due to access, we use the Leica HDS 6000 & 7000.

17. DATA CAPTURE
Every scanning target used for registration is geo-
referenced from our network of site control
(permanently available to the client post-project) using
the same first order measurement instrumentation.
This surveying accuracy allows us to rely on geo-
referenced targets to register multiple point-clouds to
millimetre accurate targets with surveying closure. This
geo-referencing method allows us to eliminate potential
accuracy degradation due to cumulative errors. We
avoid point-to-point registrations unless absolutely
required to complete an otherwise inaccessible or
problematic area.
PERSONNEL
All of the equipment used in our process is operated
simultaneously by teams of personnel (from two to
four operators but usually a configuration of three)
with one team scanning and one team coordinating
control. All personnel in the division are trained in
both scanning and industrial surveying techniques;
our unique methodology allows them to be
interchangeable, providing greater flexibility. We can
therefore verify critical tie-in points using real-time
dimensional control surveying while scanning.
Furthermore our project leaders have a wealth of prior surveying
experience in both traditional and industrial environments on
refineries. WLSL’s industrial work is currently completed under
the direct supervision of a US licensed professional land surveyor.
PROCESSING
We create real-time point cloud registrations while on-site to verify
completeness of our scans. All registrations and point-cloud post-
processing is accomplished using Leica Cyclone or LFM Server
packages depending on the clients requirements. Geometric
primary models are created in Leica Cyclone or LFM Server
depending on the native deliverable requirement. LFM Modeller,
or CloudWorx running in AutoCAD or Bentley Microstation is used
to create models of civil and miscellaneous detail where organic
shapes are necessary.
DELIVERABLES
All point cloud sets and final model deliverables are exported for import into any AutoCAD or Microstation based product
including PDMS. The key point is that our point clouds can be opened in your existing design software using simple to
learn and low-cost add-in software. There is no need for expensive new modelling software or training.
WLSL now uses Leica TruView software to provide real-time review capability for clients at their offices. Multiple
deliveries are often made to clients on an as-completed cycle to enable multiple work-fronts. For final deliverables model
data and point clouds are provided via HDD, FTP, or DVD.

UK and in India. In addition, the data was
used directly in the existing design
software, PDS, as a fit-for-purpose
deliverable.

19. 3D Laser Scan to Traditional Drawings
Warner Land surveys has significant experience in
providing our clients with end to end as-built data that
enables clients to study, plan and design.
Using our 3D laser scanner technology we are able to
capture the full external or internal detail of any boat
and any size. The 3D information, which we call a
point cloud, can then be used to create a section
through the boat at any point. Our team of skilled
computer aided design staff then use these sections
to create traditional drawings that meet our cus-
tomer’s specifications.
Objectives
Provide fast, precise, reliable and cost effective
method for creating as-built drawings or models.
Benefits
Scan data closely replicates the real world status of
any object.
