<strong>HMS</strong> <strong>100</strong> <strong>SHOLS</strong> – Installations<br />
• All Coast Guard vessels in the<br />
Nordkapp class<br />
• The Coast Guard vessel Svalbard<br />
• All the new frigates in the<br />
Nansen class<br />
• Two of the coastal express<br />
vessels “Hurtigruten” for medical<br />
purposes<br />

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

Future concepts for improved<br />
availability:<br />
- Additional Measurements in <strong>SHOLS</strong><br />
- A Landing Period Designator<br />
© KONGSBERG
Future Concepts – Additional Measurements in <strong>SHOLS</strong><br />
• Heave and heave<br />
rate. Reduces the<br />
probability for hard<br />
landings due to limited<br />
capacity of the<br />
helicopter to follow the<br />
deck dynamics.<br />
• Measure horizontal<br />
accelerations.<br />
Reduce the probability<br />
to roll-over when<br />
standing on the deck.<br />
A Motion Severity<br />
Index (MSI) is under<br />
development.<br />
© KONGSBERG
Future Concepts – Landing Period Designator (LPD)<br />
• Measures position, velocity and<br />
acceleration and calculates an Energy<br />
Index- EI value<br />
• Determines the rate a ship can move<br />
because of its hydrodynamic forces<br />
against the hull and the dynamic<br />
characteristics of the matching<br />
helicopter<br />
• Determines the risetime in seconds for<br />
the accumulated energies in a ship to<br />
produce a motion from calm to a high<br />
risk condition (from green/very safe to<br />
red/danger)<br />
• The EI value is compared to a deck<br />
availability scale displayed to the user<br />

<strong>HMS</strong> <strong>100</strong> LPD<br />
• Tested by the US Navy<br />
since 1997 and also by<br />
the Royal Navy<br />
• Part of the US Navy<br />
Dynamic Interface<br />
program<br />
• The equipment is now<br />
in its final evaluation<br />
phase by the US Navy<br />
