KONGSBERG HMS 300 Helicopter Deck Monitoring System

NORMAM-27: Suitable for operations in Brazilian waters

NOROG: Suitable for operations on the Norwegian continental shelf

3. Helicopter types and day night restrictions

The operator needs to choose according to the actual situation:

Helicopter type: Class A or Class B (based on the evaluation of the helicopter's handling characteristics during landing and ship contact phases)

Deck Category: Divided by Ship Type and Day/Night Conditions

Day and night restrictions: daytime or nighttime operations

4. Mode switching

Under the CAP 437 standard, the system has two working modes:

Pre landing mode: The helicopter approaches the deck but has not yet landed

Deck Landing Mode: Helicopter has landed and come to a complete stop

Switch to deck landing mode:

Pilot reports helicopter magnetic heading

Enter the helicopter heading in the 'User Input' view

Click on 'Enter heading'

Confirm switching to deck landing mode

Switch back to pre landing mode:

After the helicopter leaves the deck, click on "Helicopter Departure"

Confirm switching back to pre landing mode

5. Deck repetitive light control

The operator can manually turn off or turn on the deck repeating lights through the system settings. After shutdown, the system interface will display a red warning message "Helicopter deck duplicate lights have been turned off", and the status view will also show a cross symbol to ensure that the operator is aware of the current status.

6. Generate deck report

Before each helicopter operation, the system can generate a deck report for use in flight planning and safety assessment. Report generation is divided into three steps:

Edit email: Fill in recipient address and other information

Create report and screenshot: Fill in general data, meteorological observation data, deck motion data, etc

Preview and send: Check the attachment and send an email

The reports under CAP 437 and NORMAM-27 standards are "meteorological reports", while under NOROG standards they are "deck reports", with the former containing richer data fields.

Detailed explanation of user interface

1. Interface organization

The user interface is divided into three main areas:

Top bar: Display current standard and mode, ship name, location, UTC time, service quality indicator, user configuration, application menu, settings menu

Sidebar: Provides mode switching and report generation entry

Main display area: dynamically display different views based on the selected standards and modes

2. Core View

User Input View

Used to select helicopter type, deck category, day and night conditions, and input helicopter heading. In deck landing mode, display the 'Helicopter Departure' button.

Status View

Display the current system status indicator:

Green: Sensor data is stable and effective

Red: Invalid or missing data

Yellow: unreliable data

Blue: Using simulated input data

Deck wind direction and heading view

Display deck orientation, vessel heading, wind direction, and wind speed in compass form. Users can choose between a 2-minute or 10 minute average statistical value.

Meteorological data view

Display data such as air pressure, temperature, dew point, visibility, cloud cover, wave height and period. Simultaneously display QNH and QFE correction values for air pressure.

Operation Status View

Display the access status and signal quality of each sensor (motion, wind direction, navigation).

3. CAP 437 Exclusive View

Relative wind direction restriction view: graphically displays the relationship between relative wind direction and wind speed, with red and amber warning areas indicated

View of changes after touching the ship: displays the trend of changes in heading and wind direction within 30 minutes after touching the ship

Deck Landing Stability Limitation View: Displaying Deck Stability with MSI/WSI Coordinate Diagram

Touch ship restriction view: displays the maximum and limit values for roll, pitch, heave rate, and tilt

4. NOROG and NORMAM-27 exclusive views

Deck restriction view: displays limit values for roll, pitch, tilt, and heave rates

Sports summary view: displays the maximum roll, pitch, tilt, and significant heave/heave rates in the past 20 minutes

Sports history view: selectable time range of 2 minutes, 10 minutes, 20 minutes, or 3 hours, displaying real-time trends of roll, pitch, heave rate, heave cycle, and maximum heave

Data Management and Logging

1. Data recording

The system records sensor data and operational events as binary IB files, with each file corresponding to a 10 minute data fragment. These files are stored in the processor unit and can be copied to a USB storage device through the "Data Export" function under the "Tools" menu.

2. Data Conversion and Analysis

The IBReader program is used to convert binary log files into CSV format for easy analysis in tools such as Excel. The converted CSV file contains:

sports data

meteorological data

Marine environmental data

Operation Change Record

Navigation data

Configuration files corresponding to each operational variable

When exporting, the IBReader program should be copied along with the log file to ensure file format compatibility.
