Health Check

How healthy is your navigation and communication equipment on board?

The Radio Holland inland shipping Health Check increases the deployment, safety and efficiency of your inland ship and ensures that you will not be faced with unpleasant and expensive surprises.

Here’s how it works: Our technicians carry out a short but thorough inspection of your equipment. You receive a Health Check report. This report contains advice about your equipment, regulations, any required (preventive) maintenance, and if it is necessary to replace or install additional equipment.

This brings you completely up-to-date, and any equipment problems are signaled and solved at an early stage!
