Boat Survey: Kifanlo parametric analysis<\/p>\n

Presentation<\/h1>\n

Built in 1955 in Les Sables d’Olonne, the KIFANLO was classified as a historical monument in 1984. She is one of the 16 identical hull trawlers launched by the Batifort shipyard between 1945 and 1957. The Kifanlo is a tuna trawler made of wood with mixed propulsion. She is 16.37 metres long, with a tonnage of 27.51 tons, and is equipped with a 120 hp Poyaud engine. (more at https:\/\/oceam.org\/presentation-du-kifanlo<\/a>)<\/p>\n

Methodology<\/h1>\n

The work is done with Rhino and Grasshopper in order to develop a tailored tool for 3D analysis.<\/p>\n

Evaluating deformations<\/h1>\n

Then sections are spaced:<\/p>\n

\"\"<\/a> <\/p>\n

Then the idea is to compare the relative distance of each side from the axial line<\/p>\n

\"\"<\/a><\/p>\n

This is what we want to get. (sorry for upside-down dimensions)<\/p>\n

\"\"<\/a><\/p>\n

To achieve that, 2 preliminary formatting:<\/p>\n

1\/ numbering sections<\/p>\n

\"\"<\/a><\/p>\n

2\/ drawing axes<\/p>\n

\"\"<\/a><\/p>\n

\"\"<\/a><\/p>\n

This axial line is then segmented. It will give a support to measure distances from axe to the section line<\/p>\n

\"\"<\/a><\/p>\n

\"\"<\/a><\/p>\n

Now we\u2019ve got to find the intersection between those line with section curves<\/p>\n

\"\"<\/a><\/p>\n

\"\"<\/a><\/p>\n

The point dispatch gives us the possibility of creating lines from the axial line to the section line.<\/p>\n

\"\"<\/a><\/p>\n

<\/p>\n

Lines are created<\/p>\n

\"\"<\/a><\/p>\n

\"\"<\/a><\/p>\n

Now we\u2019ve got the possibility to get every lines dimensions<\/p>\n

\"\"<\/a><\/p>\n

\"\"<\/a><\/p>\n

To help reading the results, we can create a colour gradient<\/p>\n

Let\u2019s bold the lines by creating a loft. Lines are duplicated and then linked with a loft.<\/p>\n

\"\"<\/a><\/p>\n

\"\"<\/a><\/p>\n

Each length is taken. The loft is coloured depending on the length.<\/p>\n

\"\"<\/a><\/p>\n

\"\"<\/a><\/p>\n

In Rhino, it is faster to reorganise the results to have this kind of presentation<\/p>\n
