Fleet
Total Fleet >100 vessels (about 15 persons/ship)

Always-on Internet - Reasons
- Communication between ship/shore accelerated - Downloading manuals - Port details, Cargo details - Water heights - Weather and ice charts - Less printing of private e-mail
- Private e-mail (gmail, msn, …) - Chatting with home/friends - Electronic banking - Home newspapers - Surfing
-Supporting captain with PC problems -Remote install of updated software

Bandwidth a precious commodity
- Substantial bandwidth cost (airtime + initial cost) - Discussions on what crew contribution would be fair and how to enforce it.
- Some crew members ate all bandwidth , leaving nothing for their collegues
⇒ Compression ⇒ Organize charging ⇒ Organize fair distribution Middleware

Crew Policy Internet
• Get 300 MB/month free allowance (equals about 600 MB before compression) • 0.20 USD/MB above 300 MB allowance • Buy 5 – 100 USD (from leisure of their cabins) (infinitely valid) • Bring Your Own Device (no company provided PC’s) • No further restrictions (skype, etc ok) (as long as legal) • Friendly hints for controlling data usage • Unlimited internet access on special projects (waiting hours)

Crew: Infinity dashboard
Simulate a mobile device (less bandwidth)
The user can open the firewall on demand

Crew change integration
How to get crew changes automagically to ship? Webservices: - RegisterUser(…) - Signoff(UserID) - BuyCreditsFromShip(UserID,nn USD) No extra work for captain. Crew can buy extra (never expires) Fair Charging based on free monthly + additional buy on board (never expires)

Business - Crew
How do we make sure the business doesn’t drown in crew traffic?
QoS, order (most important first): VLAN IP Range Ports Description

Quality of Service (QoS) :
Implemented in the Infinity Box

Compression
Compression in reality even better: + Advertisement reduction + Local http caching + Local DNS caching

Netto 2.2 => 256 kbps ‘feels like’ 512 kbps

Notifications: • Your message has been delivered • >5 MB => Your message has NOT been delivered (rejected) • Your mail has been put on hold until the connection is restored (max 5 days). • The internet connection has been out of service for more than 5 days
=> discarded
E-mail revisited
Via VSAT e-mail cost is peanuts Via backup FBB/IOP still costly => direct mail with more intelligent control needed
![Page 17: Data-hungry applications via the “limited-capability ......Data-hungry applications via the “limited-capability” satellite network Maritime CIO Forum Rotterdam, 18th Nov 2014](https://reader034.vdocuments.net/reader034/viewer/2022050719/5f5e93f99475b7295b71747b/html5/thumbnails/17.jpg)
Telephony (VoIP)
• Increases cohesion between office and fleet
• Free of charge
• The quality of the voice is very good
• Phones can be placed anywhere on the vessel’s network
Office staff and vessels can call each other internally (4-digit number)
Technical notes:
- SIP connection between office Mitel PBX and Infinity VoIP
- Siemens DECT VoIP phones on the vessel
- Separate Voice VLAN

• Virtual vessel PC

Sensors
Sensors currently connected : - Fuel flow (IFO, MDO, Boiler) - Torque (propulsion power, shaft generator) - GPS (position + speed over ground + direction) - Speedlog (speed through water) - Wind meter - Crane control (Huisman; via sensor VLAN)
Standard interfaces…? NMEA, pulse, Volt, Ampere, modbus, … Big Data …: datalogger reduced from 1x/min to 1x/15 min; still a lot of data Not online, but via MS SQL database sync Combined with weather routing (Meteo Group SPOS)
![Page 20: Data-hungry applications via the “limited-capability ......Data-hungry applications via the “limited-capability” satellite network Maritime CIO Forum Rotterdam, 18th Nov 2014](https://reader034.vdocuments.net/reader034/viewer/2022050719/5f5e93f99475b7295b71747b/html5/thumbnails/20.jpg)
Conclusions
1) Crew : fair distribution + charging + administration in place 2) Average traffic has increased from 8 to 22 GB 3) Compression makes 256 kbps ‘feel like’ 512 kbps 4) QoS makes sure that 17% Business doesn’t drown in 83% Crew traffic 5) Direct e-mail now possible, including sophisticated control 6) Telephony brings fleet and office closer together 7) Sensor LAN now actively used

Future
Expand always-on Internet to 22 more vessels (128/256 or 128/384) Hunger for more bandwidth will remain Shift from infrastructure to applications:
web-based (on-board) applications (vessel cloud + sync to office) fuel saving (interpreting sensor data) renewed arrival/departure/noon/bunker apps (no longer messages) incident reporting app (solving large file attachment sync challenge)
how to mix map layers: private company info+weather+ECDIS? ECDIS directly connected to sensor VLAN Video (tele-medicine + tele-maintenance)
