Recon Survey

www.fugro.com7

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

www.fugro.com17

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

When Goldeneye was commissioned

www.fugro.com18

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

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

PIPELINES

in the

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

GIS for Pipelines

GIS for Pipelines

www.fugro.com34

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

• 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)
