TLDR
In this article, an initial shape setting step was performed to set the initial shape of the bell mouth and then a shape modification step was carried out to make the shape rotatable.Abstract:
Provided is a bell mouth design method whereby a bell mouth shape suitable for a ship type can be designed easily without depending on specific craftsmen. The bell mouth design method of the present invention has an initial shape setting step (Step 1) for setting the initial shape of the bell mouth 4; a three-dimensional model creation step (Step 2) for creating the three-dimensional model of the bell mouth 4 and other parts on a computer; a preliminary shape modification step (Step 3) for modifying the outer peripheral shape of the three-dimensional model of the bell mouth 4 so as to be rotatable when the anchor 3 contacts the initial shape of the bell mouth 4; a mechanical analysis step (Step 4) for performing a mechanical analysis of the condition of the anchor 3 being housed using the three-dimensional model of the bell mouth 4 and other parts on a computer; a determination step (Step 5) for checking whether the results of the mechanical analysis satisfy predetermined conditions; and a shape modification step (Step 6) for modifying three-dimensional model of the bell mouth 4 on the computer on the basis of results of the mechanical analysisread more

3 Method for bell mouth shape forming
TL;DR: In this paper, a method for shaping a bell mouth attached to a bow of a ship is described, which includes the steps of: receiving drawings for manufacturing the bell mouth, extracting input data from the drawings, forming a surface of the bellmouth from the extracted input data; comparing the surface and the drawings; and setting an installation position if the surface coincides with the drawings.

Anchor monitoring system
TL;DR: In this paper, a monitoring system measures the tensile load on a ship's rode (the cable, chain or rope connecting the ship to its anchor) with a rode load sensor and also measures the velocity and direction of the wind and the velocity of the current that produces the rode load with individual sensors.
