Abstract

The problem is to observe the hull load with a simple configuration. The solution is that the hull load observation device (10) includes an acceleration measurement unit (21), an attitude measurement unit (22), an extraction unit (30), and a load calculation unit (40). The accelerometer (21) measures the acceleration of the hull. The attitude measurement unit (22) measures the attitude of the hull. An extraction unit (30) extracts an acceleration for load observation from the acceleration, and extracts a posture for load observation from the posture. A load calculation unit (40) calculates a load on the hull using the acceleration for load observation and the attitude for load observation.

Description

technical field [0001] The present invention relates to a hull load observation device, a hull load observation method, and a hull load observation program for observing loads imposed on a hull due to waves and the like. Background technique [0002] In a ship such as a large merchant ship, the load on the hull of the ship due to navigation becomes a problem. For example, there are slamming, whipping, and the like as main causes of hull loads. Slamming is the shock produced when waves collide with the hull, and slamming is the vibration of the hull due to slamming. [0003] The accumulation of the load on the hull may cause a change in the characteristics of the hull or damage to the hull to the extent that it affects safe navigation, steering of the ship, and the like. [0004] Therefore, conventionally, various systems for observing the hull load have been studied. For example, Non-Patent Document 1 describes a ship hull load monitoring system using optical fibers and h...
