Deciding between retrofitting an old cargo ship or investing in a new build depends heavily on the company’s financial health, operational needs, and long-term strategy. Retrofitting can be a cost-effective solution for extending the life of a ship with lower initial outlay, but it carries risks related to the vessel’s age and potential hidden costs. On the other hand, a new build, though costly, offers long-term savings and reliability. Each scenario should be evaluated based on specific operational profiles and market conditions.
