Analysis Of Needs And Placement Of Zinc Anode For New Ferry Ship Buildings

Muh. Syaifullah — 2024-06-28

Marine structures (ships, offshore platforms, underwater pipes and other floating structures) in operation are not protected from corrosion. One of the biggest sources of damage to ships is caused by seawater corrosion. Until now, the use of iron and steel as the main materials for shipbuilding is still dominant. Corrosion is a degradation process of a metal due to chemical reactions between the metal and its environment. The aim of this research is how to determine the need for zinc anode and efficient installation distance as well as the costs required in procuring cathodic protection. Cavitation is a factor that often occurs around propellers or propellers. When the propeller or propeller rotates in the water, the low pressure around the surface of the propeller can cause water vapor to form and turn into cavitation bubbles. When these bubbles burst, the erosion effect on the surface of the affected object will quickly corrode. So that the installation of the sacrificial anode at the stern is installed slightly tightly. The method used to control the rate of corrosion is by protecting the steel plate using cathodic protection. Therefore, every ship that is built needs to have zinc anode planning to control the rate of corrosion on the ship's steel plates. The number of zinc anodes required for a new construction ship with a length of 72.76 m, a width of 14 m and a draft height of 3.30 m is 55 with an addition of 30% of the total number at the stern due to the cavitation factor. The design life of the zinc anode protection is 2.5 years with a longated flush mounted (welded type) type s-8, dimensions (300 mm × 150 mm × 25 mm) weighing 8 kg. The installation distance is 3 m and 1.3 m with the installation cost being IDR. 40,530,000.

Analysis of the Effect of Using Concrete Mattresses on Subsea Pipelines

Risal Risal — 2024-06-28

This Leaks in oil and gas pipes under the sea will cause pollution and threaten the ecosystem in the sea. Damage to underwater pipes caused by anchors has quite a large percentage, therefore good prevention efforts are needed so that leaks do not occur which have a negative impact on environment and economy. The aim of this research is to find out how the strength compares between pipes that use protective concrete mattresses and pipes without protective concrete mattresses when hit by ship anchors. This research uses explicit dynamic simulation using Finite Element Method software. Based on explicit dynamic analysis, deformation values and equivalent stress values are obtained after being hit by an anchor at a speed of 5,491 m/s. For unprotected pipes experiencing significant damage, when viewed from the deformation values obtained, namely amounted to 0.143 m, while for the pipe model with protection the deformation value obtained was 0.0769 m. For pipes without protection and pipes that use protection with a thickness of 0.15 m, the deformation value is both above the maximum value that has been determined, namely 10% of the diameter value and when viewed from the equivalent stress value, for pipes without protection the equivalent stress value is obtained. namely 1,150 MPa, while the pipe that uses a protector is 240 MPa, the equivalent stress value obtained by the pipe using a protector is below 780 MPa, which means that the use of pipe protectors is quite effective in reducing damage that occurs to the pipe.
