BNWAS: Bridge Navigational Watch Alarm System

What happens if the Officer of the Watch becomes unable to perform his duties?

Fatigue, sudden illness, or loss of alertness can compromise a bridge watch without any outward warning. The Bridge Navigational Watch Alarm System (BNWAS) provides an independent safeguard. It monitors OOW activity and escalates automatically when no response is detected.

Regulatory Framework

-Carriage requirements: SOLAS Chapter V, Regulation 19

-Performance standards: IMO Resolution MSC.128(75)

Operating Principle

-Dormant Period: A preset interval, adjustable between 3 and 12 minutes, during which the OOW confirms alertness through a reset, either via the reset button or other detected bridge activity.

-Stage 1, Visual Indication: If no reset occurs, a visual signal is displayed on the bridge.

-Stage 2, Audible Alarm: If the signal goes unanswered, an audible alarm sounds on the bridge.

-Stage 3, Remote Alarm: The alarm is transmitted to the Master and/or a designated standby officer.

-Stage 4, Crew Alarm: If there is still no response, additional crew members capable of taking corrective action are alerted.

Why It Matters

BNWAS does not replace the lookout or the watchkeeper's judgment. It acts as a last line of defense, ensuring that an incapacitated or inattentive OOW is detected and that a qualified person is brought to the bridge promptly.

Every reset is more than acknowledging an alarm. It is a confirmation that the watch is being kept.

VDR: The Technical Side of the "Black Box"

How it works

The system continuously collects data from bridge equipment and stores it in a protected recording unit. The data is time-stamped in UTC so that all sources can be synchronized during an investigation.

Data recorded

Date and time (UTC), ship's position, speed, and heading

Bridge audio from microphones and VHF communications

Radar and ECDIS display images

Echo sounder, wind speed and direction

Main alarms, rudder and engine orders and responses

Status of watertight doors, fire doors, and hull openings

Built to survive

Data is stored in a Final Recording Medium (FRM) inside a protected capsule, designed to withstand:

Severe impact and pe*******on

High temperature fire exposure

Deep-sea pressure, with an underwater locator beacon to aid recovery

Compliance and operations

An Annual Performance Test (APT) by an approved service provider is required to verify that all inputs are recorded correctly.

After any incident, the VDR data must be saved immediately to preserve it for investigators.

Why it matters

Accurate, synchronized data allows investigators to separate fact from assumption. That leads to clearer root cause analysis, better lessons learned, and safer operations for the whole industry.

Under SOLAS Chapter V, Regulation 20, a Voyage Data Recorder (VDR) is mandatory on passenger ships and on cargo ships of 3,000 GT and above. Cargo ships built before 2002 may carry a Simplified VDR (S-VDR) with a reduced data set. Performance requirements are set by IMO Resolution MSC.333(90) and IEC 61996-1.

Every Second Recorded. Every Incident Understood.

🛰️ MARITIME SATELLITE COMMUNICATION

Communication at sea is not limited by coastal coverage.

Maritime satellite communication gives ships reliable long-range connectivity in ocean areas beyond the reach of VHF and MF, and where HF performance can vary with propagation conditions.

🔹 Long-Range Communication

Satellite systems provide wide ocean coverage for voice and data, independent of distance from shore.

🔹 Voice & Data

Depending on the system and service, vessels can exchange voice calls, operational data, weather routing information, and crew welfare communications.

🔹 Distress & Safety (GMDSS)

Satellite services are a core part of the GMDSS:

▪️ Inmarsat services (e.g., Inmarsat-C, FleetBroadband) for distress alerting and safety communications

▪️ Iridium, recognized by the IMO as a GMDSS provider, extending coverage to polar regions (Sea Area A4)

▪️ COSPAS-SARSAT satellite-linked EPIRBs on 406 MHz for distress alerting

🔹 Maritime Safety Information (MSI)

Navigational warnings, meteorological warnings, and SAR information are broadcast to vessels via services such as SafetyNET, alongside NAVTEX.

🔹 Ship–Shore Connectivity

Commercial and operational services such as VSAT support vessel management, reporting, and coordination with shore teams.

⚠️ Good to know: VSAT and similar broadband services are used for operational and commercial communication and are not GMDSS-approved systems. They complement the GMDSS but do not replace it.

NAVTEX — Maritime Safety Information

In maritime navigation, access to reliable and timely safety information is essential for maintaining situational awareness and supporting safe voyage planning.

NAVTEX (Navigational Telex) is an automated international service used to broadcast Maritime Safety Information (MSI) to ships within its coverage area.

🔹 What does NAVTEX provide?
NAVTEX broadcasts essential navigational and safety information, including:

• Navigational Warnings
Information about hazards, changes to navigation aids, and other conditions affecting safe navigation.

• Meteorological Information
Weather forecasts, warnings, and other relevant maritime weather information.

• Search & Rescue Information
Safety messages related to SAR operations and maritime emergencies.

• Other Maritime Safety Information
Additional information considered necessary for safe navigation.

🔹 How does it work?
NAVTEX receivers automatically receive and display relevant broadcasts from designated transmitting stations, reducing the need for continuous manual monitoring of multiple information sources.

The international NAVTEX service primarily uses 518 kHz for broadcasts in English, while 490 kHz may be used for national-language broadcasts.

🔹 Why is NAVTEX important?
For the bridge team, NAVTEX provides a continuous source of standardized maritime safety information that can support voyage planning, navigational awareness, and risk assessment.

AIS — Automatic Identification System 📡

How much can a ship know about the vessels around her?

The Automatic Identification System (AIS) is a key tool for maritime situational awareness, allowing vessels and shore-based stations to exchange important information automatically through VHF communication.

🔹 What does AIS provide?
AIS can transmit and receive information such as:

Vessel identity
Position
Course & speed
Navigational status
Vessel type and other static data

🔹 Why does it matter?
AIS helps bridge teams build a clearer picture of surrounding traffic and supports safer navigation, particularly in busy or congested waters.

🔹 AIS ≠ Radar
AIS and radar provide different types of information and work differently. AIS relies on transmitted data, while radar detects targets independently. Together, they provide a more complete picture of the surrounding environment.

⚓ Maritime Essentials #5 | VHF, MF & HF Compared

Not all marine radio communication works the same way. VHF, MF, and HF each serve a different communication range and operational purpose — but knowing when each one is used is essential for effective communication at sea.

🔹 VHF → Short Range

🔹 MF → Medium Range

🔸 HF → Long Range

1- VHF — Very High Frequency (156–174 MHz)

VHF operates on line-of-sight propagation, with an effective range of roughly 20–30 nautical miles. It's used for bridge-to-bridge communication, port/VTS operations, and ship-to-ship coordination. Channel 16 is the international calling and distress frequency, and VHF also carries DSC for automated short-range distress alerting.

2- MF — Medium Frequency (300 kHz–3 MHz)

MF uses groundwave propagation, reaching 100–300 nautical miles. Under GMDSS, 2182 kHz is the traditional distress and calling frequency for voice, with 2187.5 kHz used for DSC alerting. MF covers the gap between VHF's coastal range and HF's open-ocean range, essential for Sea Area A2.

3- HF — High Frequency (3–30 MHz)

HF relies on skywave propagation, with signals reflecting off the ionosphere to travel thousands of nautical miles — near-global coverage. It's essential for Sea Area A3, supporting both voice and NBDP for distress and routine traffic, with dedicated DSC distress frequencies (e.g., 4207.5, 6312, 8414.5 kHz). Propagation quality depends on solar activity and time of day.

In summary: VHF for local coordination, MF for regional coverage, HF for long-range communication — together forming the layered structure of the GMDSS framework.

🚨 GMDSS Series | Part 2 — Understanding the 5 Key Functions

In our previous GMDSS posts, we explored the essential equipment used in maritime distress and safety communications.

But GMDSS is not simply a collection of radio and satellite equipment.

It is an integrated safety system built around five essential functions:

01 | DISTRESS ALERTING 🚨

The ability to send a distress alert is the first critical step in an emergency.

Equipment such as EPIRB, DSC, MF/HF and VHF DSC enables vessels to transmit distress alerts through appropriate communication channels.

02 | SEARCH & RESCUE

After a distress alert is received, identifying and locating the vessel becomes crucial.

SART, AIS-SART and Rescue Coordination Centres (RCCs) support search and rescue operations by helping rescuers locate vessels and survival craft.

03 | MARITIME SAFETY INFORMATION 📡

Vessels need reliable safety information to navigate safely and respond to developing hazards.

Systems such as NAVTEX and recognized satellite services deliver navigational warnings and other Maritime Safety Information.

04 | COMMUNICATION 📻

Effective communication keeps ships connected with other vessels, shore stations and rescue services.

GMDSS incorporates VHF, MF/HF, satellite communication and portable GMDSS equipment to support essential communications.

05 | EMERGENCY POWER ⚡

During an emergency, loss of the main power supply must not mean loss of communication.

GMDSS batteries and emergency power supplies help keep essential safety equipment operational when it is needed most.

🌊 The strength of GMDSS lies in how these functions work together.

From sending the initial distress alert to supporting search and rescue, receiving safety information, maintaining communication, and keeping essential equipment powered — every function plays a role in protecting life at sea.
