Sensors increasingly play key roles in monitoring the material and functional condition of naval, merchant marine and maritime industry machinery and operational and structural spaces. Choosing parameters for monitoring functions can be challenging. Selecting and proving sensors that will be sufficiently robust to perform reliably for an economic service-life can be truly daunting. A good illustration is the trial of tank fluid and coating monitoring sensors applied to test service in U. S. Navy CHT (collection, holding, and transfer) tanks.
