Certainly! "Orbis" is actually a proper noun and doesn't have an official shortened form. However, it's common for people to refer to "Orbis International" simply as "Orbis" in casual conversations or informal writing. This is a common way to refer to organizations or companies by using the first word of their name. In this case, "Orbis International" becomes "Orbis" when using the shortened form.
