Industrial Ethernet and This Project
•
•
•
•
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
SHARKFEST '09 | Stanford University | June 15 –18, 2009
The Project – Why YR20?
• 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!

SHARKFEST '09 | Stanford University | June 15 –18, 2009
What does it Compare To?
SHARKFEST '09 | Stanford University | June 15 –18, 2009
MV Well Enhancer - Stats
• 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.

What Does This Network Compare To?
•
•
•
•
•
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!

Vessel Networks
• 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.
– VLANs for:
• 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).
• CCTV
– 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.
SHARKFEST '09 | Stanford University | June 15 –18, 2009
Traffic Engineering
• 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.
SHARKFEST '09 | Stanford University | June 15 –18, 2009
Tools
• 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
SHARKFEST '09 | Stanford University | June 15 –18, 2009
Commissioning Process
• 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

Thanks to the Wireshark Community!!
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.
