Описание (английский):

This document specifies requirements for watertight and oiltight manholes of the current types with bolted covers, for general shipboard use other than for pressure vessels. It specifies the dimensions for the holes in the plating and the number, size and position of the fasteners. It is applicable to manholes of raised coaming, surface mounted or recessed cover types. The details of the manholes are at the discretion of the manufacturer.

Overview

ISO 5894:2018 - Ships and marine technology - Manholes with bolted covers - specifies requirements for watertight and oiltight manholes with bolted covers for general shipboard use (excluding pressure vessels). The standard defines nominal sizes, dimensional details for openings, and the number, size and position of fasteners for common manhole types (raised coaming, surface-mounted and recessed covers). It also covers material, manufacturing quality, gasket requirements and interchangeability of components.

Key topics and technical requirements

Scope and types: Applicable to manhole types AO, AE, BO, BE, CO, DO (raised coaming, surface mounted, recessed).

Dimensions and nominal sizes: Clear opening sizes (l × b) and associated dimensions are given in the standard’s figures and tables for each type and nominal size; dimensions are in millimetres.

Fasteners and coordinates: Number, size and positioning of bolts/nuts are specified, with recommended fastener coordinates listed (see Table 7). Threaded fasteners follow ISO 262 metric thread selection. Examples in the standard reference M20 fasteners (hole Ø23 mm) and auxiliary fastener sizes.

Material and strength: Cover plate, ring/coaming, bolts and nuts must be marine-approved material with a minimum yield strength of 235 N/mm². Corrosion-resistant equivalents are permitted.

Gasket requirements: Gasket materials must be suitable for oil, seawater and freshwater service and free from asbestos.

Manufacturing and quality: Surfaces must be flat, free from pitting and safe to handle; dimensional accuracy (cover, gasket, hole spacing) must ensure interchangeability. Marking, handles and jacking-up bolts details are included for practical use.

Designation: Standardized designation format (e.g., “Manhole cover ISO 5894 - AO - 600×400-8”) is provided.

Applications and who uses it

ISO 5894:2018 is used across the maritime sector wherever standardized, watertight or oiltight manholes are required:

Shipbuilders and shipyards for fabrication and outfitting

Naval architects and marine designers specifying access openings

Manhole and gasket manufacturers ensuring interchangeability

Classification societies and regulatory bodies referencing dimensional and material criteria

Ship operators and maintenance crews for repair, replacement and inspection guidance
