1.1 This guide provides an overview and guide for the selection and implementation by shipowners and operators of a Fleet Management System (FMS) network of computer services in a client/server architecture (see Fig. 1). The FMS is based upon a wide area enterprise network consisting of an unspecified number of Shipboard Information Technology Platforms (SITPs) and one or more shoreside Land-Based Information Technology Platforms (LITPs), which provides management services for the shipping enterprise. The FMS can be understood as a computer system comprised of one or more LITPs and one or more SITPs. It can be characterized as mission critical 24

365 (24 h/day, 365 days/year).
1.2 The SITP (see Fig. 1) provides a set of software services, including:
1.2.1
Communications Services
, to communicate between vessels and with shore via multiple wireless communication technologies;
1.2.2
Data Acquisition Services
, providing access to shipboard system data as required for use by other systems and management purposes; and,
1.2.3
Executive Services
, providing software process administration and control.
1.2.4 In total, the SITP provides the capability for multiple shipboard computer systems to share data with each other and to communicate with shore-based management or other vessels or both.
1.3 The SITP is understood to consist of integrated hardware, software, a data repository, and standardized procedures, which provide the ability to send, receive, process, transfer, and store data or messages in digital form in a common mode from shipboard systems or administrative utilities or both, and from designated sources outside the network, for example, systems accessed through wireless communication services, such as satellite, VHF, HF, and so forth. Shipboard systems include navigational, machinery control and monitoring, cargo control, communications, and so forth. The SITP also will provide the capability for the remote administration and maintenance of associated computer systems aboard the vessel.
1.4 The SITP requires an underlying hardware and network infrastructure, including a shipboard computer local area network (LAN), file servers, workstations, wireless communications transceivers, cabling, other electronic and optical devices, video display units, keyboards, and so forth.
1.5 The SITP also requires underlying system software providing network operating system (NOS) services, DBMS services, and other system software.
1.6 There also is a layer of shipboard application systems, which are designed to capitalize on the FMS infrastructure to share data with other shipboard systems and management ashore. Those systems also would be able to capitalize on the remote management capabilities of the FMS.
1.7 The LITP is an asset that can exchange operating and administrative data from individual ships and maintain a DBMS to support fleet management and other maritime applications. The LITP will support data repositories, file servers, workstations or personal computers (PCs), and a communication hub providing connectivity to distributed satellite services, VHF (very high frequency), HF/MF (high frequency/medium frequency), and land lines. The DBMS makes possible the development of knowledge-based

by providing the ability to retrieve, process, and analyze operational data.
1.8 This guide does not purport to address all the requirements for a SITP, which forms a path for data for direct control of the operation or condition of the vessel or the vessel subsystems.
1.9 In all cases, it shall be possible for all units of navigation equipment resident on the Navigation Equipment Bus to operate and display essential operating data independently of the FMS.
1.10 In all cases, it shall be possible for all units resident on the Control, Monitoring, and Alarm Bus to operate and display essential operating data independently of the FMS.
1.11 In all cases, it shall be possible for all units resident on the Communications Bus to operate and display essential operating data independently of the FMS.

====== Significance And Use ======
Competent information management is essential for safe and productive operation and regulatory compliance. A short list of the functions affected includes decision aids for navigation, communications, ship handling, machinery control, cargo operations, maintenance and repair, personnel records, and environmental protection.
The shipbuilding and shipping industries have identified a need to develop comprehensive standards and guides for implementing computer-based shipboard data management systems.
The FMS may include single or multiple SITPs and single or multiple LITPs and provides the means to integrate shipboard and shoreside computer systems with multivendor connectivity, distributed processing, and electronic data interchange between noncompatible networks, computers, workstations, and peripherals and maintain databases, which promote safety of life at sea, protection of the environment, and operational efficiencies throughout the life cycle of the vessel/fleet. The FMS may incorporate satellite gateways to coastal communication hubs providing access to land-based networks, such as telephone lines, facsimile, e-mail, and expanded satellite services through land earth stations.
The SITP can be configured to provide the ship’control center with access to local control centers, such as for cargo operations, which may be located on the main deck.
This guide has provisions relevant to all components of the FMS platform including the ship earth station, interface devices for subsystems and administrative systems connected to or forming part of the network, communication services, and certain land-based facilities under the direct control of the ship’management.
It is the intent of this guide to provide guidelines for the design and implementation of open client/server architecture for computer and communication networks for shipboard and shore-based applications.
This guide is intended to assist vessel owners, designers, shipyards, equipment suppliers, and computer service providers in the development of contract technical specifications, which detail the services to be supported, performance required, and criteria for acceptance for specific FMS installations.
