ABSTRAK

Pada Field Project yang berjudul proses pengembalian bentuk plat yang terdeformasi dengan proses fairing di bangunan atas kapal PT PAL Indonesia . Masalah yang paling banyak plat mengalami deformasi adalah pada bagian bangunan atas kapal dikarenakan plat pada bangunan atas relatif tipis sehingga akan mudah mengalami deformasi. Saya akan mengambil contoh bagian plat yang terdeformasi di bangunan atas pada kapal chemical tanker 24.000 LDWT dengan nomor S 242 yang dibuat oleh PT. PAL INDONESIA Pada faktanya dilapangan banyak sekali plat yang terdeformasi pada bagian bangunan atas kapal sehingga perlunya perbaikan agar plat yang terdeformasi kembali ke bentuk semula berdasarkan rule standart bangunan kapal baru dari quality controlquality assurance. Untuk mengatasi masalah tersebut maka dipakailah proses pemanasan lalu pendinginan plat secara ekstrim yang sering disebut dengan proses fairing. Proses fairing merupakan suatu metode yang dilakukan untuk memperbaiki sifat keuletan dan ketangguhan suatu pelat setelah ditekuk dingin. Perbaikan sifat mekanis yang disebabkan oleh pemanasan pada garis desain diakibatkan oleh perbedaan antara elongasi penguluran pemanjangan dan pemuaian antara sisi yang dipanaskan dengan sisi yang belakangnya. Maka dengan proses fairing ini plat yang tidak rata di bangunan atas dapat diperbaiki sesuai standart.


ABSTRACT

In the Field Project entitled proces0 flatness return of shape plate due to welding voltage with fairing process in deck on the tanker ship S242 PT. PAL Indonesia. The problem that most deformed plate is in part due to the building of the ship building plate on top is relatively thin so it will be easily deformed. Ill take the example of the plate is deformed in a building on the chemical tanker hips LDWT 24 000 with a number S 242 made by PT. PAL INDONESIA. In fact the field a lot of the deformed plate in the building of the ship so that the need for improvements to the deformed plate back into shape by rule standards of new ship building to quality control quality assurance. To solve the problem was used heating and cooling plates process is often called the fairing process Fairing proces is a certain method for repaired persevering and integrity steel after give a refrigaration. Repair charateristic of mechanism that proceed because heating in the design line of different between elongation extendion elongation expansion between side is heating and side is cooling. So with this fairing proces not flat of plate in the building top ship can be repaired with standart.
