About Windcat

Windcat Workboats owns and operates a growing fleet of over 44 offshore crew transfer vessels, mainly in the European offshore wind sector, but also in the oil and gas industry and outside Europe. The vessels are designed and built by Windcat and, as such, include over 16 years of experience in the field. The vessel’s layout and propulsion is optimised to transfer personnel offshore in a safe and comfortable environment. Windcat’s organisation provides the highest quality of service, enabling the charterer to perform their work offshore without delay. The focus on safety has the highest priority in the operation of the vessels and can be found throughout the organisation. The size of our fleet and the variety of vessels ensures that we can deliver the right vessel to each project.




Crew Transfer Vessel




Oceansat 4G Pro

The Challenge

Crew Transfer Vessels from windcat sail continuously between the coast and wind farms which are only a few nautical miles outside 4G range. The investment for an expensive VSAT system is therefore not justified and the limits to receive 4G signal are constantly being sought. And even though we are getting very close, unfortunately there is still no service level agreement for 4G that guarantees signal receiption. So, as mentioned, it is important that the ship stays within 4G as long as possible in order to offer the crew and its passengers internet for crew wellfare, but more importantly, operational internet traffic. But as soon as the CTV is out of range of 4G, a smart system must ensure that only the captain can still send E-mails for operational internet traffic. The rest of the internet traffic must then be blocked to prevent high bills. Oceansat has completed this question with Oceansat Pro.

“We can now manage ships from the office, so we know exactly whether they vessels are online. We now no longer miss a single update and, also important, no longer receive billshocks. How it works? We are connected up to 45nm from the coast to the 4G network and if that does not work by accident, a satellite connection will take over automatically ”


The Solution

Oceansat 4G Pro. This sophisticated maritime system keeps the crew online via 4G even 35 nautical miles from shore and when out of 4G range it picks up a satellite connection for mandatory operational data transfer, which keeps them online even 100 nautical miles from shore. When the system detects when the 4G connection is down, it automatically switch to the satellite connection. Oceansat software knows the connection is on satellite, and only allows E-mail or VoIP to avoid high billshocks via Inmarsat L-band. At shore, the IT department has a clear view on the vessels network via het Incontrol management software. It knows IP addresses, realtime-insight in users and data traffic and real-time administration by amending the firewall, QOS or in/outbound policies on the fly. This way the captain can concentrate on sailing the vessel and the IT department can give maximum support to their colleagues at sea.
