Abstract

Most of the heat exchangers onboard are in the form of shell and tube. Another form is the plate heat exchanger (PHE). The advantage of PHE is that it has a very large displacement surface at a small volume of tools. Selection of suitable gasket material for PHE is very important. It is intended for a long service life of PHE. The research has been conducted at the shipyard of PT. JMI Semarang to find out the location and cause of plate leakage from PHE. PHE observations and improvements are carried out when the ship is docked at the shipyard. Repairs were made directly in the form of operational data and manual book PHE type of M15.

Abstract

PT Yasa Wahana Tirta Samudera (PT YWTS) is a subsidiary of Samudra Indonesia as one of the shipyards in Indonesia, has docking facilities such as Grafing dock (8000 DWT capacity),sliding with 3 docking rails, and airbags technology for and launching barges. Insufficient or excessive air pressure, inappropriate number of airbags and arrangement of airbags that are too close or too far away will have an impact on the ship launching process which may be disrupted and detrimental to the shipyard or owner.This study aims to determine the number of airbags and the distance between airbags during the process of launching the Virgo Sejati 177 with a length of 300 feet.The methods used in this study are From the calculation results of the number of airbags needed in the process of launching the barge, 18 cc airbags were needed. From the calculation results of the number of airbags needed in the process of launching the barge, 18 cc airbags were needed.barges with a cross over type of arrangement is 6.652 - 10.75757 meters.
