An Ageing Fleet Needs Greater Care
Shipping is investing heavily in the next generation of vessels, fuels and propulsion technologies, but a large part of the existing fleet will still be trading well into the next decade. This will mean the steel structure must be protected for much longer. For instance, Clarksons data from July 2025 showed that 38% of global ...
Shipping companies are investing in newer vessels and technologies, but a significant portion of their existing fleet is still in operation for many more years. A study by Clarksons showed that 38% of global fleet capacity is older than 15 years, including 30% of bulk carriers and 33% of container ships. Corrosion is the most common cause of hull issues, and its frequency increases as ships age.
Rather than focusing solely on the cost of coating structures during drydockings, owners should consider the ongoing maintenance required over the ship's remaining lifespan. This shift in perspective transforms corrosion protection into an integral part of the ship's value throughout its life. Newer coating systems, like Steelpaint's single-component, moisture-curing polyurethane coatings with zinc-rich primers, offer superior protection against corrosion in harsh environments.
These coatings have proven to require minimal maintenance even after three years, making them a cost-effective choice for ageing fleets. The use of such advanced coatings on critical areas like lashing bridges and tank tops can significantly reduce the need for repairs and extend the life of the steel structure, making corrosion protection a crucial aspect of asset management for older vessels.
