The Hydrographic Society In Scotland
• Circa 1996 - In the first instance a Geophysical Pipeline RouteSurvey would be conducted to accurately establish seabed and sub-bottom conditions. This would be conducted using a purpose-built dedicated Geophysical Survey Vessel
• Routes are based on• Soil Characteristics
• Debris and obstructions
• Topography
• Pipeline design/needs
• Various sensors are utilised• Echo sounder
• Sonar
• Profilers
• Magnetometers
• Navigation and positioning information is recorded, processed and later applied to specific data-sets
• Gathered data is processed and/or interpreted to produce a final product aimed at presenting decision makers with detailed information to enable project planning and pipeline design
• Data is typically presented within hard copy reports as charts, written content and fly-sheets
• Additionally CAD data may be delivered in native formats – NOTE NO GIS!

• GIS products were not specified within scope of work (focus on cartographic
output) – charts were the main deliverable and great significance imposed upon
them
• Large duplication of effort and time consuming
• Charts latest revision not underlying data
• Every change moved further away for source

How GIS was
embraced
EARLY
ADOPTERS
www.fugro.com16
The Hydrographic Society In Scotland
• Oil and GIS (Survey) serviced exclusively by a CAD environment
• Dominated by Bentley Microstation not AutoCAD (engineering product)
• Providing initially only a Paper Product
• Over time the actual .dgn /.dwg files were delivered to client – was data used?
• GIS of no interest despite obvious added value
• In parallel Cable survey clients harnessed GIS
• Days of pouring over hundreds of charts while selecting a route were replaced
by adopting a GIS based solution with a delta called Makaiplan
AS I’VE MENTIONED
HOWEVER
When Goldeneye was commissioned

The Hydrographic Society In Scotland
• Oil and GIS (Survey) serviced exclusively by CAD environment (finishing)
• Dominated by Bentley Microstation not AutoCAD (engineering product)
• Providing for many years a Paper Product
• Over time the actual .dgn /.dwg files were delivered to client – what did they do?
• GIS of no interest despite obvious added value
• In parallel Fibre Option Cable survey clients harnessed GIS
• Days of pouring over hundreds of charts while selecting a route were replaced
by adoption of Geomedia based solution with a delta called Makiplan

The Hydrographic Society In Scotland
Put simply – in GIS you start with a
map and add data - it’s an
environment to query append and
make decisions about data

GIS
and Pre-Lay
Today
www.fugro.com20
The Hydrographic Society In Scotland
We’ve taken a look back in time to see
how our workflows operated during a
Recognisance Survey and understood
no GIS usage
Lets look at how a typical Pre-Lay is
conducted at present
Today’s Pre-Lay
www.fugro.com21
The Hydrographic Society In Scotland
Dedicated Vessels Same Equipment
to Recon but different platform
Today’s Pre-Lay
www.fugro.com22
The Hydrographic Society In Scotland
• What is a Pre-Lay Survey
• Survey of the seabed along a pipeline/cable route immediately prior
to installation.
• Why do we need a Pre-Lay Survey
Identify potential hazards or obstructions before laying/trenching of
pipelines or cables
To further investigate previously found debris - Recon
To establish existing seabed bathymetry and existing pipeline/cable
positions
• How do we do it
ROVs are commonly used for Construction Pre-Lay surveys
Cameras and Multi-beam are mounted on the ROV
The ROV will fly along the design route acquiring data
ROV Pilots will also use the scanning sonar in real time to locate
potential hazards
If a hazard is detected the ROV may break off the line to inspect the
target
Potential hazards
Objectives of a Pre-Lay Survey

Engineers
Mobilise and maintain the equipment on the vessel
Surveyors
Monitor vessel and ROV position and data

Processing Work Flow
www.fugro.com25
The Hydrographic Society In Scotland
• The main objective when processing a Pre-Lay
survey is to obtain the seabed depth along the
intended route
• Events are created real-time from the video and their
details will be further reviewed offline.
• The Multibeam data will also be cleaned and
assessed to look for boulders/objects that are
beyond the range of the camerasMultibeam targets
Seabed markers
Processing Work Flow
www.fugro.com26
The Hydrographic Society In Scotland
Common deliverables that would be supplied to the client are as follows:
Position Listings – provide seabed depth along the route
Event Listings – provide details of the locations of all hazards
DTMs – provide the client with the overall terrain of the route
Data is usually charted

Client Deliverables
www.fugro.com28
The Hydrographic Society In Scotland
• GIS still not fully embraced but positive signs
• GIS does exist within project lifecycle however is specific to limited areas
• Today we would typically have a GIS data set for upstream projects
(Geophysical)
• Site Survey
• Platform Survey
• Proposed Route Survey - Recon
• No requirement to deliver GIS versions of Pre-Lay but is now delivered at Post-
Lay (as-built)
GIS usage slowly building
www.fugro.com29
The Hydrographic Society In Scotland
• Data Schemas exist Pipeline Open Data Standard or ArcGIS Pipeline Data
Model
• Post Lay and touchdown information could be updated with annual inspection
data each year
• Centralised database approach ability to integrate data from different sources
and during the various stages of the project

FUTURE
www.fugro.com31
The Hydrographic Society In Scotland
• GIS ideally cannot conveniently coexist alongside CAD in a “production”
environment – this means you must either do the same work twice one way or
another or create GIS at final delivery to avoid edition in two places
• In general the CAD environment is not efficient due partly to the number of people
involved and requirement to migrate from one software package (format) to
another
GIS for Pipelines – No More CAD
www.fugro.com32
The Hydrographic Society In Scotland
• So we should move away from CAD based solutions with ridged data
• As pipeline moves you need the associated events to move with it - GIS
• Perform year on comparisons (analyse) - GIS
• Use the advantages of linear referencing - GIS
• Information to high levels of granularity should be associated against a point or
feature - GIS
• Ability to hold design or tolerance info – collaboration - GIS

The Hydrographic Society In Scotland
• GIS needs to play a central part – host and disseminate
data (public facing portals)
• Attention then focuses on the data (one instance) easing
QC and revision management
• No need to apply updates to various products
• Minimises potential for error
• Eases QC burden – shouldn’t be a burden
• If the data is right the products should be right

• Platform Surveys
• Route Survey
• GIS usage at Construction stage
• Pre-lay
• As-laid
• Touch Down
• OOS
• During annual inspections

• While pushing data into Spatial Database Engine avoid low-key tools (Python
programming)
• Develop standalone robust license free applications – Think Database at this stage
Postgres
• Use GIS to create the deliverables if we must - BUT preference is to work with the actual
data thru GIS desktop or portal (Clients)
