Why develop an integrated monitoring sys Based on feedback our customers there is increasing requirements for improve efficiency and reduce risk We believe this is best served by taking an integrated systems approach all the way from the sensors to the delivery of the final information
Monitoring systems - diverse applications, common architecture

Presentation Notes
Lets just consider a typical system All these functions are part of the system and common across many applications Across the board there is commonallity in different applications
Ashtead’s common building blocks philosophy• Reducing cost and risk through
• Re-use of common hardware and software modules
• Elimination of proprietary interfaces
• Elimination of duplicate engineering
• Use of open data communication channels
• Design for robustness, reliability and easy operation
7
Result: Highly responsive and effective service with reduced asset inventory
Presenter
Presentation Notes
We have adopted a building block philosophy Reduces cost and risk Use common hardware and software Eliminate bespoke interfaces Remove duplication of engineering Open data communication architechture
Increased demands for smarter information in real-time

Presenter
Presentation Notes
Ever increasing demand for efficient data service Real time subsea to topside comms U/W displays Logging Data broadcast over network Monitoring from onshore We have developed a core system that can handle these requirements
Open subsea communications• Key consideration – integration with all common subsea
communications methods
• Ability to work efficiently within existing LBL and USBL acoustic array topologies
• Ability to operate with existing vessel acoustic systems
Optimised for use with:
• Kongsberg HiPAP/cPAP & Cymbal
• Sonardyne 6G wideband
• Teledyne Benthos acoustic modems
• Any transparent modem link

Presenter
Presentation Notes
Open communications is fundamental We need to be able to work within existing subsea networks and acoustics is one One example is the avoidance acoustic interference between data and positioning systems Technology have moved along a long way in the last few years and we need to be future proofed
Our track record in enhancing our clients’ performance
Presenter
Presentation Notes
We now have a few examples of projects we have delivered See the frame and the cNode What I will now show is a number of projects which all use the same building blocks Talk more as we progress
Buoyancy stability monitoring systems, Guará - Lula (Brazil)
EPIC scope for 4 buoyancy supported SCR riser systems with large submerged buoys supporting 27 steel catenary risers
The buoyancy modules required monitoring during tow-out, installation and subsequent hang-off of the SCRs to provide information on the buoyancy structure stability during these key stages
The stability monitoring system consisted of an instrumentation package that was retrievable by ROV. Instruments measured inclination, heading and depth as well as providing precise position measurement
System data transmitted to topside vessel via an acoustic modem and via a dedicated umbilical
Extended autonomy with power management and optimisation was included to allow for extended periods where the system would remain dormant until re-awakened

SS7 Brazil 4 subsea buoys to be installed to 200m in 2000m water Subsea Catenery Riser This was a very high profile job and was the first project of this type System provided real time stability monitoring giving heading, pitch, roll and depth Project lasted for 18 months and then rolled onto further monitoring projects which still out working on
Suction pile manifold installation monitoring - Quad 204 (UK)
Subsea structures incorporating suction piles can be difficult to install without incurring high levels of stress on critical weldments
This project required monitoring of multiple key structural parameters simultaneously during installation to avoid damage to the structures and to allow a single survey package to provide all data from deck to final installed position
Ashtead Technology developed a real time monitoring service that provides critical data on the shape of the structure and the relative attitude of the piles
With positioning and orientation data also incorporated, this fully integrated one-pass installation monitoring package reduces vessel time and technical risk
In addition to the real-time offshore benefit, valuable data is also available that allows post installation analysis of the structure response to refine models for future structures

VIV and FIV monitoring (Brazil)
This client had a requirement to classify the modes and extent of vortex induced vibration of 10” and 12” flow-lines with free-spans in 10 locations on an asset for a period of 2 years
The client invited Ashtead Technology as their sole sub-contractor to present a solution to undertake this work scope
The system required tight integration of accelerometer, gyroscope and power optimisation systems along with data processing electronics into a very small overall package
Also included in this package were Doppler current profilers and turbulence meters

Suction pile installation monitoring (North Sea)
This client required an attitude monitoring system for installation of suction piles
The system required configuration to operate with Kongsberg SimradC-Node, configured for EM3000 protocol under Cymbal acoustic protocol
Ashtead Technology integrated C-Node into the AMS system via the FlexiTxT display unit
The system also provided battery management and remote control functions

Offshore jacket & mono-pile installation positioning (EMEA)
This client required an integrated data package for positioning and installation of an offshore steel jacket for a middle East project
These projects required GPS position, heading and attitude to be acquired and transferred over a single UHF radio communications channel
Ashtead Technology integrated GPS position data with fibre-optic gyro data utilising the programmable capabilities of the FlexiTxT unit and transferred data from the foundation structure via UHF data telemetry

Open data networks for multi-vessel operations (North Sea, SEA)
Sharing of survey and inspection data across multiple vessels has been a challenge for the subsea sector
New technology has however provided a means of multi-casting data across an entire project and to onshore
Using intelligent networking technologies designed specifically for vessel operations, and having ATEX approval for hazardous areas, Ashtead Technology has provided a new capability in monitoring inspection operations aboard an FPSO which was openly shared across vessels
This technology allows global access key inspection information in real time and is also being used between platform and vessel and vessel to vessel for construction and IRM operations
Data connectivity both offshore and onshore

Maximising production uptime is vital for all operators This client had a critical issue in keeping deep-water riser systems and their flex joints fully operational
Gulf of Mexico experiences particularly high volumes of marine growth and a solution was needed to provide a one-pass cleaning and precision metrology inspection of flex joints
Ashtead Technology offers a unique solution incorporating cameras, lights and lasers onto a Flex Joint Cleaning Tool
