HMS 100 SHOLS Operation - Start-up Procedure 1. Select SHOLS configuration day or night 2. Enable logging and select Start in Run menu 3. Input weight for the helicopter 4. Select helicopter operation 5. Select procedure for the selected operation 6. Select wanted exterior light indication (Off, Red or Auto)

HMS 100 SHOLS – Main Goals ƒ Automatic method to calculate whether the helideck motion is within the SAP-90 limits or not. ƒ Go or NoGo for operations based on SHOLS calculations ƒ Visual landing aid on the helideck ƒ The complete helicopter operation can be compared to limits on all procedures simultaneously ƒ Helicopter mission planning tool ƒ Reduce the stress level for the crew and pilot during landing and take-off

Future concepts for improved availability:

- Additional Measurements in SHOLS - A Landing Period Designator

© KONGSBERG

Future Concepts – Additional Measurements in SHOLS ƒ Heave and heave rate. Reduces the probability for hard landings due to limited capacity of the helicopter to follow the deck dynamics. ƒ Measure horizontal accelerations. Reduce the probability to roll-over when standing on the deck. A Motion Severity Index (MSI) is under development.

© KONGSBERG

Future Concepts – Landing Period Designator (LPD) ƒ Measures position, velocity and acceleration and calculates an Energy Index- EI value ƒ Determines the rate a ship can move because of its hydrodynamic forces against the hull and the dynamic characteristics of the matching helicopter ƒ Determines the risetime in seconds for the accumulated energies in a ship to produce a motion from calm to a high risk condition (from green/very safe to red/danger) ƒ The EI value is compared to a deck availability scale displayed to the user © KONGSBERG

Green Deck Deck Stable (EI value 0-1.74) Green-Amber Deck Available Energy in Deck (EI value 1.74-4) Amber Deck Available Considerable Energy in Deck (EI value 4-10) Red Deck Deck Out-of Limits (EI value >10)
