Bridge Navigational Watch Alarm System Suppliers

A Bridge Navigational Watch Alarm System (BNWAS) sounds an alarm if the officer of the watch becomes unresponsive. SOLAS Chapter V Regulation 19 has required BNWAS on most ships above 150 GT since 2014. Without a working unit, the ship cannot legally sail.

Buying the right BNWAS is a long-term decision. Service support, spare parts availability, and class approvals all flow from the choice of supplier. Bridge Navigational Watch Alarm System suppliers vary widely in regional reach and after-sales coverage.

Main Components of a BNWAS

A typical BNWAS package includes:

Main controller and timer unit
Bridge reset buttons (usually two or three)
Motion sensors for hands-free reset
Alarm sounders for the bridge, master's cabin, and crew areas
Visual flashing alarm indicators
Connections to GPS and VDR for status logging
Backup battery and power supply
Operator manual and class certificate.

Most BNWAS suppliers ship the system as a single package matched to the ship's accommodation layout. Sensor count and sounder placement scale with vessel size.

Brands on the Commercial Market

The BNWAS market is led by Daniamant, Furuno, JRC, Tokyo Keiki, McMurdo, and Marine Technologies. Daniamant holds strong share on European newbuilds. Furuno and JRC dominate Japanese shipyards. Tokyo Keiki and McMurdo cover the mid-market. Smaller regional makers serve specific national flags.

Each system carries IMO type approval but uses different reset codes, service software, and wiring layouts. Suppliers of BNWAS with direct manufacturer agreements deliver with full type approval certificates and matched commissioning support.

Newbuild vs Retrofit Installations

A newbuild BNWAS goes in during yard fit-out. The vendor and yard coordinate wiring and accommodation alarm placement during the design phase.

A retrofit takes more planning. Existing alarm panels must be tied in. Cabin sounders may need new wiring runs. Most retrofit jobs take three to seven days at berth, depending on cable routing and accommodation layout.

How to Choose a BNWAS Supplier

A BNWAS lasts 15 to 20 years on most ships. The wrong supplier creates support problems for the rest of that period. Before signing, confirm:

IMO MSC.128(75) type approval for the model
Class society certification matching your flag state
Service network covering your trading region
Spare parts are stocked for at least 15 years after delivery
Commissioning and crew training are included in the price
Warranty of 24 months minimum on a newbuild package.

Reliable suppliers provide all six without negotiation.

Integration with Other Bridge Systems

A modern BNWAS does not work in isolation. It connects to GPS for time-stamping, the VDR for incident recording, and the central alarm panel for escalation routing. Some integrated bridge packages include BNWAS as a software function rather than a separate unit. Others run it as standalone hardware. Both approaches meet SOLAS, but standalone units are easier to service and replace at the end of life.

Frequently Asked Questions

Can a BNWAS be bought separately from the bridge package?

Yes. Most ships fit a standalone BNWAS even when the bridge integrator offers an embedded option. Standalone units are easier to replace and service across different brands of bridge equipment.

What documentation comes with a new BNWAS?

The package includes the type approval certificate, an operator manual in English, a wiring diagram, a class survey checklist, and a warranty card. Keep all paperwork in the ship's technical file.

Are BNWAS units interchangeable between ships in a fleet?

The hardware is, but the wiring loom and sensor placement are vessel-specific. A spare unit held ashore can move between ships in the same class series, but rarely fits a different design without modification.
