Construction Support
Offshore Construction Support involves positioning and surveying activities essential for the installation of offshore
structures and pipelines in marine environments.
Safe and successful offshore construction operations rely on precise, assured and reliable data concerning
surface and subsurface locations and status. This is especially true in harsh environments and
challenging conditions.
Securing the right support services can make all the difference when dealing with project-critical time,
cost and performance objectives.
Fugro provides comprehensive offshore field development, construction support and pipeline survey
services designed to meet broad and specific needs of offshore construction contractors.
Life of Field Support
Fugro’s Construction Support Services are designed to address marine installation, construction and maintenance activities across the entire life of
field development.
We provide precise positioning, survey support and monitoring during the tow-out of
structures and pre-fabricated pipeline bundles; the installation of platforms and jackets;
the placement of subsea infrastructure and the trenching of pipelines and cables.
Thereafter, we offer ‘as-built surveys’ such as upheaval buckling analysis and OOS
(Out-Of-Straightness) along with annual inspection and maintenance.
Contributing a world-renowned fleet of ROVs and highly-trained and respected technicians
and engineers, Fugro provides access to ground-breaking technology in underwater
acoustic positioning and in ROV control and metrology. In effect, all requirements
from evaluation through to decommissioning and reparation are catered for.
Dimensional Control Surveys
Some construction support projects call for specialist pre-project planning using
3D simulations, structural modelling and real-time 3D visualisation monitoring
during critical operational phases.
Fugro is fully equipped to provide all these and more, providing additional support during:
- Load-outs and tow-outs of structures where tight tolerances are involved
- Float-over positioning for decks on jackets
- Subsidence surveys to detect differential movement across structures
- Precision water level surveys
Pipelay Support Services
Fugro offers pipeline installation contractors a range of services to ensure that
the client’s specifications regarding right of ways, avoidance of obstructions and
trenching are achieved.
Accurate site information is essential for successful offshore positioning. Fugro’s proprietary
regional databases contain vast volumes of geographic information
concerning existing facilities, pipelines, wells and hazards for offshore field developments.
These are used to assist clients in planning projects and assuring safe operations.
We also provide an integrated survey support service using our state-of-the-art construction
support vessels with integrated ROVs, ideally suited for pipelay operations.
Fugro services include:
- Lay barge positioning and remote monitoring of anchor drop locations
- Pipeline touchdown monitoring
- Pipeline trench profiling for buried lines
- Positioning of mattresses for pipeline crossings
- Sonar monitoring of pipeline crossings during lay operations
- Positioning of pipeline end terminations (PLET) within target boxes
- Post-lay surveys
- As-built surveys and pipeline depth of cover surveys
Spoolpiece and Jumper Metrology
We are committed to providing a matchless subsea metrology service.
This includes offering extremely accurate in situ measurement between pipeline
flanges for rigid link-engineering of spool-pieces and jumpers.
Our surveyors use only the latest and most advanced measuring systems to ensure
absolute precision in three dimensions. In addition, dimensional control services are
provided at fabrication yards to guarantee that spools and jumpers will fit when installed
offshore.
Deep-water Services
Deep-water oil and gas developments demand innovative solutions to deliver complex facilities, safely and reliably into challenging environments.
That’s where experience and professional expertise really counts. Fugro’s
personnel excel at creating unique solutions that confront the difficulties faced by
construction engineers, optimising turnaround and budget parameters and providing
invaluable peace of mind.
Our services in deep-water developments include:
- Development drilling - positioning drill centre layouts
- Inertial Navigation Systems (INS)
- Underwater Acoustic Positioning (LBL and USBL)
- Pipeline cut-to-length measurements
- Umbilical and flowline measurements
- Remote monitoring and stand-alone navigation
- Project management
FPSO Installation Support
Fugro has the tools and experience required for installation of FPSO production facilities at remote sites far from existing infrastructure.
Services include:
- Positioning of pre-installed mooring systems
- Flowline and riser hook-up to seabed production facilities
- Shuttle tanker positioning and docking services
- Field support ROV services
IRM and Decommissioning
Fugro works closely with its clients to establish the parameters and objectives
of their projects, contributing vast international experience of IRM
(inspection, repair and maintenance) and decommissioning projects.
We combine this with pioneering technological innovations and substantial inhouse
resources. These include our world class subsea acoustic pipeline inspection
services, which use the latest generation of ROTV, and our Risk Based Inspection
methods designed to increase uptime, reduce maintenance costs and
further protect the environment.
Our aim is to provide a wholly integrated set of disciplines capable of performing
the most challenging of remote inspection and intervention techniques with precise
positioning, latest inspection technology and modelling services.
