In 2002, The National Maritime Electronics Association - NMEAestablished the Instrument network on ships NMEA 2000. This is largely used today. NMEA 2000 is a low-cost serial data network operating at 250 kbits/second utilizing the Controller Area Network (CAN) integrated circuit (IC). CAN was originally developed for the automotive industry, and now is used in numerous industrial applications and produced by dozens of IC manufacturers.

Driven by a desire to both utilize the existing “bus”, plus the need to have information at the wheelhouse, some vendors have utilized this network for music, comfort control and lighting control. However, it is not uniform. Disparate systems are commonplace.

Ships and boats are relatively compact and the “entertainment and comfort” areas are generally confined to upper decks/ cabins.

This paper considers multiple options to introduce IoT for these areas with the benefits and disadvantages of each.

It is open for discussion on the best practice for alternative scenarios.

Outline/Structure of the Talk

  1. 3 Network layers envisaged by NMEA
    1. Description of speed, data control and acquisition of each
    2. Bridge between networks
  • Lack of uniform standard or approach for entertainment and comfort controls
  1. Central operator command and control of a network (driving a ship, operating from a control station)
    1. Critical areas: Requirement for secure information, lack of clutter, data integrity
    2. Interest in “alarms” and system status from “entertainment and comfort” but NOT content.
  2. What constitutes “non critical “ information
    1. Entertainment
    2. Comfort controls
  • Convenience functions
    1. Selected lighting
    2. Voice command: Communication from communal areas to galley for service
    3. Blind and sunroof controls
  1. What constitutes “grey area”
    1. People count – who is “on deck” – video recognition systems
    2. Time and attendance by staff
  2. IoT solutions and benefits:
    1. Common SSID and Wifi throughout for IoT
    2. Disparate SSID reserved for critical control over wifi.
  • Hub and mesh network for each communal area and each cabin.
  1. Common User App
  2. Remote area access (Communal to cabin)
  3. Visual recognition (Ship command likes to know where key people are)

Benefits, risks and opportunities.

Learning Outcome

Separation of command and control networks from Entertainment Comfort and Convenience. How the two can co-exist

Target Audience

Anyone working in environment of IoT and Controlled networks (marine, mining, construction markets similar to marine).

Prerequisites for Attendees

None other than broad understanding of IoT.
