Inclination Testing for Marine Industry Equipment
May 25th, 2022
Testing marine equipment involves simulating the harsh environment typical for recreational craft and onboard commercial ship applications. Test lab equipment must replicate accelerated moisture and high humidity, temperature extremes, and corrosive atmospheres. High vibration and shocks are also tested to evaluate marine systems against the mechanical stresses from propulsion or other motor driven ship systems.
Another stress that is unique to the marine environment comes from pitch and roll inertial attitude changes of the ship during rough seas and initial acceleration. These conditions are simulated using static and dynamic inclination testing.
Static inclination testing evaluates the ability of equipment to perform when the vessel is off plane for extended periods such as when a vessel is listing to one side or another. Dynamic inclination testing evaluates equipment operation during pitch and roll from rough seas.
Many types of marine equipment are tested for inclination. For example, ship controls are evaluated to confirm normal operations such that components remain seated, connectors stay mated, actuators hold position, and the cabinet doors remain closed. Motorized or moving systems are tested to evaluate how angular momentum of a spinning motor or dynamic system changes with the angle of inclination. Storage batteries are tested to confirm they operate normally and without electrolyte leakage when angled to the extremes.
Inclination tests are specified in the commercial marine industry equipment standards. These include:
- IEC 60092-504
- IACS E10
Inclination requirements are also incorporated into type certification specifications from the major IACS classification societies.
