ACO Marine supply bespoke tank designs for most shipboard requirements in both stainless and black carbon steel construction. Systems such as fresh water, food waste and wastewater can be offered in capacities up to 400m³. ACO Marine may be able to offer larger tanks subject to final design and production approval and evaluation with the customer. ACO Marine welcomes the opportunity to discuss all specialist customer requirements and to develop suitable project feasibility studies. Our preferred material is generally AISI 316L Stainless Steel as black steel, with special internal coating, is prone to corrosion.
