or “Why things just have to work!”
17 June 2009
President | YR20
June 15-18, 2009
YR20 Group – a Texas Corp. – Operating Cos in Houston, Texas and Aberdeen, Scotland
Over 100 years of experience in mission critical networking and telecommunications
Totally independent - objective, fact-based services completely aligned with our customers
We operate utilizing our in-house tool-set backed up with years of hard experience to offer our customers optimal solutions to their networking and telecom needs
Network Engineering and Analysis as a Service
No capital investment in equipment
We supply the expertise and equipment on a simple contractual basis
Full range of services – lab simulating and testing, incident and problem management, traffic engineering and capacity planning, equipment evaluation, application evaluation and optimization
Sales or Leasing of Standards Based Network Data Capture Appliances
Standards based – Training and Support Available, Extremely Rugged with Remote Management – High Performance
Simply Stated – Industrial Ethernet must work
Lives and huge economic values are at stake
Focused on plant, process, and control
Directly contributes to the revenue stream of an organization
Installation requires detailed approval by a classification society such as DNV, LR, ABS, etc. to get insurance
“There must be a tie-wrap on the cable every metre”
Likely to be in hazardous environments
The MV Well Enhancer was conceived by Helix ESG to be the largest, most high tech offshore service vessel available
Very high market visibility
Helix ESG demanded that this vessel ‘simply must work!’
Lives, Safety and Revenue were at all risk
YR20 was identified as the Company that could make this happen.
Design, implementation, FAT, and ongoing support
We had the tools, technique, reputation and ability to get it done!
132m long - 1 1/2 football pitches
12,000 ton displacement - more than a USN Ticonderoga Class Cruiser
Top of Tower is almost 50m above sea-level (10 storey building).
Accommodation for 120 people.
Diesel electric power for propulsion and equipment with total of 15MW of generation capacity in x6 engines in x3 engine rooms.
Dynamic Positioning Class 3.
18 saturation divers in x4 chambers living under pressure.x2 ROVs.
A ship with crew
Plus a power station
Plus an airport
Plus a hotel for 120 people
Must cover the needs for work, safety, personal use, and regulatory
All over the equivalent of a poor rural DSL 512k x 512k 140,000 km long!!
You cannot design this without knowing the traffic!
Wireshark is a key and critical item in getting it right!
A very pensive Mr. Everitt!!
Industrial Ethernet round vessel
total of 25 switches
Resilient gigabit core.
Approximately 100 miles of copper installed PLUS fibre!
Total of 25 configured VLANs of which about 8 are in service now.
General desktop PCs, printers, etc. About 40 devices.
Voice; About 30 VoIP devices. (there is a full general PBX on the vessel that is not connected).
About 60 CCTV channels incl. inside monitoring of winches, etc., external monitoring for decks, cranes, etc. diver helmet video and audio feeds, ROV camera feeds, etc.
Control; x5 separate VLANs for control systems
Likely to be more in the future
Ranges from Modbus/TCP, ProfiNet, etc to HTTP.
Dual VSAT antennae for shoreside link.
All traffic divided into classes at Layer 2 for LAN priority using IEEE 802.1P marking and QoS/queues in switches.
All traffic divided into classes at Layer 3 for VSAT WAN priority using DiffServ marking and QoS/queues in routers.
Note: LAN trunk capacity is 1Gbps - no bottlenecks at this time.
Note: VSAT/WAN traffic capacity is symmetric 512kbps - significant bottlenecks from start.
Have to deliver all the operational and social requirements for a very large industrial facility and the 120 people who live and work there over the equivalent of a very poor DSL service. This is commonly known in the offshore oil industry as the "elephant and the drinking straw" trick.
Simply would not be possible to do this correctly without tools like Wireshark.
YR20 PCAP-Probes™ to collect traffic 7x24
Large amounts of data captured to be analyzed
Up to .5 T / month
RSD to divide the traffic into Layer 2 or Layer 3 classes of traffic for examination
Wireshark for packet-level analysis
L1 analysis for automated analysis of large volumes of traffic to spot problems
L2 being developed and tested
Proper Initial Design
FAT – Field Acceptance Testing
Use of all tools to confirm correct configuration and traffic flows at layers 2 and 3
If operational problems occur traffic can be compared to commissioning traffic to see what's different.
Ability to respond very rapidly to operational issues
Without remarkable tools like Wireshark it simply would not be possible for us to design, build and operate systems like this for serious industrial use.
