Don't just take our word for it

Since 2019, I have primarily used Greywing to manage security risk assessments, intelligence and management of security tasks. Our office teams have critical and sensitive security information easily on hand – just one click ahead. No time to source from different providers. In the past, it was a time-consuming challenge to compare different data analytic. With Greywing, we have a tool to assess the real security threat We can provide our crews, customer and ship owner with the insights they need. Greywing is used to decide if we have a go or no-go situation and what can be done to mitigate the threat. \n\n However, I was so impressed by their recent work on the crew change crisis that I had no hesitation in recommending it to our crewing team. We are now better prepared to plan crew changes and verify the latest regional rules which may restrict our ship operation. Greywing is the innovation our industry needs.

Greywing has produced a very interesting and innovative web-based crewing solution during covid crises. It’s about accessing all relevant information regarding crew changes in one platform which will have the access to our vessel position/ next port of call (through AIS data), port restrictions, restrictions in crew sourcing areas, information from IATA, port agents, crew nationalities etc. They also integrated the platform with flight info and our crewing software (compas) which gives us all possible information to quickly plan and decide on a crew change where it is possible. It is very time saving solution as previously we used look at a lot of data from various sources, do a lot of back and forth communication with agents in home port as well as joining port, travel providers etc. which is time consuming and at times delays our decision in executing crew changes.
