DDS

System integration in offshore shipsHow we applied DDS and redefined system topology

R&D Manager Ulstein Power & Control– Develop and maintain Automation & Control

products and platform

– The company sells packages and products in the maritime industry, with a main focus on Offshore Supply Vessels

– We sell system integration and products

– This ranges from Power switchboards, ship automation, bridge and navigation equipment

Main topic of interest

This presentation is to address our challenges to make a configure to order control system architecture, which lasts for the lifetime of the ship

Challenges

Business

Standards and second source

Responsibility and liability of being total integrator

Legacy products, SCADA system, components, code, old Windows versions – technical debt over 30 years

Business

2015

- challenging offshore market

- tough competition

- In-house competence vs hiring

Second source and standards

Ulstein - long term investment in control systems

DDS - the next 30 years ?

- two real suppliers (RTI and Prismtech)

Alternative standards?

- OPC UA is becoming important

- Industry 4.0

DDS – OPC UA bridging can become important

Second source Hardware

2014- only Schneider done some tests

2015- Bachmann, Wago and Phoenix API with possibility for C++ and DDS implementation

2016Ulstein will use DDS invariant to hardware make

Responsibility of a total integrator

2015

- rules and regulations are being developed

- responsibility vs willing to pay

- who will pay if …

How to handle legacy, ship next 30 yrs

- Technical debt

- Old SCADA tools

- Non supported windows plattforms

- Proprietary PLC’s

- Form, fit & function

- Outdated rules and regulations

- Now: invariant to this, hope DDS will last …

Further challenges

- Retrofit code on new platforms

- Open source vs proprietary

- Scalability

- Vulnerability

DDS for communication between applications

Configurator for delivery of control system, GUI and documentation

Qt/QML for Graphical User Interface

Hardware Technology

Marine approved electronics

IEC 60945, Marine Equipment Directive

Few vendors and low volume hardware with limited options and high cost

All components are COTS (Commercial off the shelf)

Serial (All) Configuration

IO Controller:- Application for converting hardwired & serial signals

(CANBus, NMEA, ModBus RTU) to and from DDS- Simple distributed signal alarms- Vendor dependent API

Network traffic- DDS on the Ethernet

DDS Network Architecture- General

- DDS for all data traffic between controller and other devices- DDS is a «Cloud» concept, supports «Industrial Internet of

Things»- Less CPU load on controller- Faster system- No network protocol handling, DDS takes care of all network traffic- Data is distributed and available everywhere- DDS gives more reliable data collection, provides more redundancy
