GOST 18174-83 PDF

Full title and description

GOST 18174-83 — Automated remote control systems of main (marine propulsion) diesel engines. General technical requirements. The standard establishes general technical requirements and functional, reliability and safety criteria for remote automated control systems used to start, stop, regulate speed and reverse main ship diesel engines operating with fixed‑pitch propellers (directly or via reversing gear).

Abstract

This standard defines required functions, performance and reliability characteristics for shipboard remote automated control systems (DAU) for main diesel engines — including control logic, command processing, interlocks, transition and emergency behaviours, permissible static error for speed control, and requirements for testing, power supply and maintainability. It was approved by the State Committee for Standards of the USSR in 1983 and introduced into force on 01.01.1985.

General information

• Status: Active / действующий (listed as in force in current catalogues of GOSTs).
• Publication date: Approved 20 September 1983; date of introduction (in force) 1 January 1985.
• Publisher: Approved by the State Committee for Standards of the USSR; published by Izdatel'stvo standartov (Moscow), 1983.
• ICS / categories: Shipbuilding and marine engineering / main propulsion and drive systems (classifier entries reference 47.020 and related ship engine categories).
• Edition / version: Original 1983 edition (replaces ГОСТ 18174-72).
• Number of pages: Editions are short (published variants list between about 3 and 6 pages depending on print/electronic copy).

Scope

The standard applies to remote automated control systems (systems of дистанционного автоматизированного управления, ДАУ) for main ship diesel engines that drive fixed‑pitch propellers either directly or through reversing gear. It specifies overall functional requirements, reliability and maintainability expectations, interaction with other ship control posts, and requirements for operation under shipboard environmental and power conditions.

Key topics and requirements

• Required functions: start/stop (including emergency stops), continuous stepless change of crankshaft speed and propeller direction using operator controls, processing of operator commands according to defined algorithms.
• Control performance: limits on static error to ensure overall speed error (including regulator and engine) does not exceed 3% of nominal speed.
• Interlocks and safety: independence of DAU interlocks from other control system interlocks, blocking to prevent simultaneous control from multiple posts, and prevention of unintended starts or speed increases on power loss.
• Command processing and availability: guaranteed processing of the operator’s last command regardless of prior command order; switching control between posts (remote, central, local) at any time with switching time not exceeding 10 s (operator transition time excluded).
• Redundancy and manual fallback: provision for independent emergency or manual stop circuits outside the DAU and the ability to operate the engine from local or alternative control posts if DAU is disabled.
• Power supply and maintainability: capability to be powered from general ship sources and (or) engine-derived sources; repairability and restoration in shipboard conditions; defined service life and resource (minimum service resource example: ≥ 5000 operating hours without adjustment, unless otherwise specified).
• Environmental and installation classes: device executions and placement categories per GOST 15150‑69 and protection types as required by related documentation.

Typical use and users

Primary users are shipyards, marine systems integrators, engine and control‑system manufacturers, vessel owners/operators, classification societies and design bureaux involved in propulsion control systems. The standard is used during design, acceptance testing, commissioning and for defining vendor contractual requirements for automated remote control systems on vessels.

Related standards

The document references and works together with other GOSTs and technical requirements such as ГОСТ 10150‑82 (environmental/test conditions referenced for control chain testing), ГОСТ 21753‑76 (requirements for control forces), ГОСТ 15150‑69 (placement and climatic categories) and various standards/technical conditions specific to particular engine types or subsystems. It replaces ГОСТ 18174‑72.

FAQ

Q: What is this standard?

A: GOST 18174‑83 is a Soviet (now CIS) state standard specifying general technical requirements for automated remote control systems of main ship diesel engines (DAU). It sets functional, performance, safety and reliability requirements for such systems.

Q: What does it cover?

A: It covers required control functions (start/stop, speed and direction control), command processing, permissible control errors, interlock/safety behaviour, switching between control posts, power and environmental requirements, maintainability and minimum service resource expectations.

Q: Who typically uses it?

A: Shipbuilders, marine control system manufacturers and suppliers, classification societies, ship operators, and designers specifying or approving propulsion control systems.

Q: Is it current or superseded?

A: Catalogues and document vendors list ГОСТ 18174‑83 as действующий (in force) while noting it replaced ГОСТ 18174‑72; users should verify applicability against current national/regional rules and any more recent maritime or GOST/R standards that may be mandatory for specific applications.

Q: Is it part of a series?

A: It is part of the body of GOST standards related to ship machinery, propulsion and marine automation; it cross‑references other GOSTs for environmental classifications, testing and specific device requirements.
