Technology is often not a cost centre and can be a competitive advantage for the right company, but Maersk is not and probably doesn't need to be a tech company (although I guess they could have a tech-forward strategy).
IT, as in, what it takes to have a computer per employee that they can use, phones, productivity software, etc, is almost never going to be a competitive advantage. It's almost always going to be a cost-centre, definitely so for a company like Maersk.
However, when technology is called upon to interface between the deeply technical (operations analysis for solving efficient container shipping and fleet Management), the thousands of people and manual handling and data entry operations per day, in just about every country and climate possible, then your IT operations are non-standard.
