Introduction

VISTA is a set of standards, tools and services designed to help DNVs partners and customers in the maritime industry standardize and contextualize sensors and other data channels. We combine industry standards with free and commercial tools and services to give the industry a broad set of opportunities to embark on their standardization and digitalization journeys.

What is Vista

Standards​

We believe the most advanced and valuable contextualization standards available today in the maritime industry consist of:

  • DNVs Vessel Information Structure (VIS)
  • ISO 19847 - Shipboard data servers to share field data at sea
  • ISO 19848 - Standard data for shipboard machinery and equipment
  • ISO 19848 annex C - DNV naming rule

In the following sections of this documentation we provide a high level introduction to these standards.

VIS​

DNV’s naming standard utilizes the Vessel Information Structures (VIS) - an information model created by DNV in 2005 and maintained ever since to support classification services.

VIS provides the master information used as basis for the classification processes in DNV. An important part of VIS is the Generic product model (Gmod), a functionally oriented model describing the vessel. The Gmod and its use in DNV's classification processes are described in Vindøy (2008). Link to PDF on site- see below.

ISO 19847​

ISO 19847 is a standard for a shipboard data server, defining requirements for functionality, performance, and data handling. The standard addresses details regarding ship-to-shore communication and shipboard data server configuration, including defining an API to store and query datachannels using naming rule specifications from ISO 19848.

ISO 19848​

ISO 19848 standardizes data concepts and data structures. It provides the foundational data templates for ISO 19847 compliant data server configuration. The standard defines:

  • Sensor measurement data (Time Series data) in two different forms - Tabular data or Event data
  • Sensor meta data (Data Channel Property)
  • Systematics for sensor naming with suitable naming rules and templates for standardized Data channel IDs (UniversalID and LocalID)

DNV naming rule (ISO 19848 annex C)​

ISO 19848 defines the LocalID as a unique and standard identification of each sensor or data channel onboard a given ship. The "dnv-v2" naming rule defines how such a LocalID can be generated using reference libraries and associated codebooks from VIS. The reason for using the version suffix "v2" is to distinguish it from the first version of the naming rule "dnvgl-vis" presented in the initial publication of ISO 19848 in 2018.

The reference library used in the "dnv-v2" naming rule is "vis", i.e., DNV’s Vessel Information Structures information model used for ship classification.

Tools and services​

We provide tools to cover the whole standardization journey, from contextualization to analysis.

  • Learning tool - free tool to interactively learn the buildup of standarized Data channel IDs using DNV's naming rule. Read more here
  • Gmod viewer - free tool to interactively explore the Gmod in VIS for the creation of Data channels IDs. Read more here
  • Mapping tool - ML-powered commercial tool to map and contextualize data channels, assisting in converting proprietary sensor names into fully standardized Local IDs. Read more here
  • Lab - commercial tools for data analytics which enable a fully digital representation of the data channels available on a ship based on the standardized data channels (a digital twin), and the import and analysis of sensor data streams. Read more here
  • Vista SDK - free and open source SDK, bringing all the standards together, codyfing the rules and data models therein described. Read more here
