WORLD CLASS – through people, technology and dedication WORLD CLASS – through people, technology and dedication © KONGSBERG © KONGSBERG Presentation of existing SHOLS system and future concepts for improved availability By Kongsberg Seatex AS Finn Otto Sanne Harlans Seminar 2007 © KONGSBERG Agenda 1. Introduction 2. The SHOLS system – SAP-90 – The HMS 100 SHOLS system – Present installations 3. Future concepts – Additional measurements – Landing Period Designator, LPD © KONGSBERG Introduction - Kongsberg Seatex A company within the Kongsberg Maritime AS Established in 1984, located in Trondheim with 90 employees Product areas: – – – – Surface Positioning Reference Systems (GPS/Glonass/Galileo) Automatic Identification Systems (AIS) Attitude sensors, like the motion sensor MRU and Seapath Helideck Monitoring Systems (HMS) We are the SHOLS system supplier to the Norwegian Navy © KONGSBERG Kongsberg Seatex HMS 100 SHOLS (Ship Helicopter Operating Limits) A Computer Aided SAP-90 © KONGSBERG HMS 100 SHOLS - An electronic version of SAP-90 © KONGSBERG HMS 100 SHOLS – Electronic description of operations © KONGSBERG HMS 100 SHOLS - Configuration of Operations & Procedures © KONGSBERG HMS 100 SHOLS – Observed parameters Images: ForsvarsNett © KONGSBERG HMS 100 SHOLS - System Description © KONGSBERG HMS 100 SHOLS – Part locations Bridge operator station Met sensors Light panel FDO display & waveoff MRU © KONGSBERG HMS 100 SHOLS - Processing SAP90B SHOLS Data Motion Data Wind Limiter Motion Limiter MDM Limiter Met.

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) © KONGSBERG HMS 100 SHOLS Operation - Lights Panel Symbols DAY GO NIGHT (NVG) © KONGSBERG NOGO WAVE OFF HMS 100 SHOLS Operation - Lights Panel Dot-matrix panels Symbolic representation Flashing or steady Light intensity rating: 5500cd/m2 Adjustable intensity Heating available Dimension: 600X600X175 mm © KONGSBERG HMS 100 SHOLS – Installations All Coast Guard vessels in the Nordkapp class The Coast Guard vessel Svalbard All the new frigates in the Nansen class Two of the coastal express vessels “Hurtigruten” for medical purposes © KONGSBERG HMS 100 SHOLS – Main Goals Automatic method to calculate whether the helideck motion is within the SAP-90 limits or not. Go or NoGo for operations based on SHOLS calculations Visual landing aid on the helideck The complete helicopter operation can be compared to limits on all procedures simultaneously Helicopter mission planning tool Reduce the stress level for the crew and pilot during landing and take-off © KONGSBERG Future concepts for improved availability: - Additional Measurements in SHOLS - A Landing Period Designator © KONGSBERG Future Concepts – Additional Measurements in SHOLS Heave and heave rate. Reduces the probability for hard landings due to limited capacity of the helicopter to follow the deck dynamics. 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) Measures position, velocity and acceleration and calculates an Energy Index- EI value Determines the rate a ship can move because of its hydrodynamic forces against the hull and the dynamic characteristics of the matching helicopter 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) 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) Wave-Off HMS 100 LPD Tested by the US Navy since 1997 and also by the Royal Navy Part of the US Navy Dynamic Interface program The equipment is now in its final evaluation phase by the US Navy © KONGSBERG WORLD CLASS – through people, technology and dedication WORLD CLASS – through people, technology and dedication © KONGSBERG
