Abstract
INSPECTION OF CHECKING THE THICKNESS OF BOTTOM PLATE SHIP MV. GLADIOLUS SEJATI IN PT. JANATA MARINA INDAH 1 SEMARANG ACCORDING TO THE RULES OF PT. BIRO KLASIFIKASI INDONESIA PT. BIRO KLASIFIKASI INDONESIA (Persero) is a State-Owned Enterprise (BUMN) appointed by the Indonesian government as an institution whose function is to inspect construction on ships and other vessel equipment. The inspection is called inspection or survey. Inspection of ships is prioritized for ships that have a length of more than 20 m or gross tonnage of GT 100 or more, or which are driven by a prime driving force of 250 HP or more than 250 PK. The writing of this paper aims to compare and practice between theories that have been obtained in lectures and in library studies, as well as document studies with conditions carried out in land practice by PT. BIRO KLASIFIKASI INDONESIA so that the hopes of the authors in the implementation of the land practice can add knowledge and insight for writers and readers and of course as a correction for PT. BIRO KLASIFIKASI INDONESIA to be better in the future. From a variety of data collection methods the authors use qualitative methods in data collection. Qualitative data is data in the form of words, not in the form of numbers, qualitative data is obtained through a variety of data collection techniques such as interviews, document analysis, focused discussions, or observations that have been stated in field notes. Based on the author's observations and when he went to the field during ground work practices the author draws conclusions during inspections in the field the inspector uses tools such as ultrasonic tests, hammer trials, trial pits, and linear dial gauges and in the implementation of inspections using the provisions of PT. BIRO KLASIFIKASI INDONESIA. And how to repair the plate and remove with cipping and painting methods. Based on the data collected, the authors draw conclusions. The tool for checking bottom plate thickness has been set by PT. INDONESIA CLASSIFICATION BUREAUs used include: Ultrasonic tests, Hammer experiments and hammering tests, Test holes or test holes and Linear dial gauges. In the inspection check the thickness of the bottom plate in the implementation there are several work steps that are in accordance with standard procedures including: Preparing PPE, cleaning the plate from rust, paint and dirt attached by tapping the plate using a hammer, making sure the surface is clean from dirt, then applying a couplant evenly on the part you want to inspect using ultrasonic thickness. This is done to facilitate the propagation of ultrasonic waves in the probe to the test object, calibrate the instrument first before carrying out checks, the calibrated probe is attached to the workpiece then moved gradually evenly on the part to be inspected, noting the conditions based on inspection results with chalk or a marker. Take photos based on the results of tests conducted to report equipment and record all inspection results on the hull of the ship. In the practice of onshore work carried out by the author also shown how to repair and replace the bottom plate according to the rules of PT. INDONESIA CLASSIFICATION BUREAU: Cipping / stamping, painting the hull in the ship and painting the hull of the ship. Keywords: Inspection, Bottom Plate, dock ship
