NORMAM-223: Offshore helideck regulation (Brazil)
The Brazilian Maritime Authority standard for the certification and registration of helidecks on vessels and offshore platforms operating in Brazilian jurisdictional waters.
What is NORMAM-223?
NORMAM-223 (NORMAM-223/DPC) is the Brazilian Maritime Authority standard covering the certification and registration of helidecks on vessels and offshore platforms operating in Águas Jurisdicionais Brasileiras (AJB).
In industry discussions you may still hear it referred to by the older shorthand “NORMAM 27”. Today, NORMAM-223 is the standard used for helideck certification and registration, and related operational requirements, in Brazil.
What the standard covers
NORMAM-223 is structured across chapters that span the helideck lifecycle and operations, including:
Registration, certification and design
Registration and certification, design, and the physical characteristics of the helideck.
Visual aids and operations
Visual aids, operational procedures, and communications and navigation expectations.
Official document

NORMAM-223/DPC
The official publication from the Brazilian authority. It includes its own revision and substitution notes: use those to confirm you are working from the correct version.
HMS and recording requirements
Helideck Monitoring System
NORMAM-223 states that every ETEX M unit must have a Helideck Monitoring System (HMS): equipment providing wind, temperature and helideck motion information, supported by data storage, reporting tools and critical alarms to help safe air operations.
Audio and video monitoring
NORMAM-223 also includes operational checks for video, audio and data recording associated with the HMS, including verification of recordings before air operations.
Using NORMAM-223 in practice
Operators typically use NORMAM-223 as the baseline reference when confirming helideck certification and operational requirements for Brazil, alongside any supporting aviation procedures relevant to the aircraft or operator.
