We have designed and digitized SHOL charts for these VTOL aircraft types
By manufacturer's origin
SHOL design solutions

We designed more than 8400 digital Ship–Helicopter Operating Limits (SHOL) charts for a wide range of helicopters and helipads :
-
From 1 150 kg to 33 400 kg aircraft.
-
Up to rotors with a diameter of over 24 m.
-
From 6m radius up to 14 m x 14 m pads.

We create SHOL diagrams tailored to your needs and digitalize your existing charts
SHOL operations
Aviation operations on ships, offshore platforms and rigs:
-
SAFER
-
SIMPLER
The HEOL app (iOS) integrates SHOL digital charts into your crew's EFBs, improving the air-safety and performance of your flight operations.
Achieve operational gains of between 20% and 35%, depending on the case.
MARGO is designed for:
-
Rig and ship crew: flight deck officers and airbosses.
-
Helicopter pilots

SHOL design training
We provide training courses on landing and take-off issues in offshore areas.
We train future designers of your diagrams.
One- to two-week training courses, depending on level:
​

MARGO for SHOL design ensures a fully integrated process with your organization's internal network and verifies the integrity of the data.
MARGO for SHOL design software suite will make it easier for you to create your SHOL charts and use them in your organization.
​
This software suite is known by the French Ministry of Armed Forces as ZEPHYR-HEOL

End-to-end systems, it includes the creation tools, the validation workflow and the operational interface to deploy SHOLs on your ships and helicopters, with dedicated applications (Windows and iOS).​

Zephyr-HEOL suite has been in operational service with the French Armed Forces (French Navy) since July 2024.
​
Full Operational Capacity (FOC) was reached in autumn 2024.
​
On board all helideck vessels, from OPVs to aircraft carriers, LHDs and destroyers with all their embarked helicopters, whatever their origin: naval aviation, air and space, army, customs, civil security, allies & partners helicopters.
ZEPHYR-HEOL is the continuation of the ZEPHYR-H project awarded in May 2021 with the AUDACE prize for the French Navy by the Marechal Leclerc de Hauteclocque Foundation and the French Minister of the Armed Forces with the support of its innovation agency (Agence de l'innovation de Défense).
