Abstract

Wellhead is one of equipment used in oil and gas drilling process. In the process of moving wellhead from one place to another, often used lifting equipment such as eyebolt. The use of lifting equipment to assist the lifting process and to make it easier and safer. Eyebolt is a threaded hook that serves as a lifting tool. To know the safety of eyebolt when used, an analysis of the mechanical behavior of the eyebolt is required. In addition, the different angle of lift will affect the maximum stress, strain, displacement, and Factor of Safety (FOS) values significantly. To know the comparison of angle difference is done simulation on software Solidwork with value of 575.604 N. The simulation process is done with angle 35°, 45°, 60°. The maximum stress occurs at an angle 35 ° that is 195.765 and safest FOS occurs at an angle 60° that is 2.7, it means if angle of lifting larger are used safer.

Abstract

The character of the ship's hull will determine the speed and movement of the ship. Ship engine power to overcome resistance is influenced by the hull of the ship so that in doing the design it is necessary to calculate precisely. This research is a further study related to the installation of wireless control devices and the design of unmanned hulls but with a different hull and engine shape. The conclusions obtained from this study are the main size of the ship are as follows: LWL = 66.74 cm; B = 32.07 cm; T = 4.91cm; Cb = 0.338. The ship has pre planning at speed: 2.5 - 4.75 knots with 6.09 – 19.6 N resistance and froud number values between 1.028 – 1.952, then experience planning at a speed of 3.5 knots with resistance values starting at 5.59 N with froud number starting at 1.439. To reach the speed of 10 knots, the ship needs around 102 W of power. The object of the ship investigated above is the Batam State Polytechnic Gurindam ship, where the ship was once used for the national fast boat contest in Indonesia. Hopefully with this research, it can provide a knowledge related to the resistance that occur and, in the future, will be used as the basis for the development of the ship to be better designed.

Abstract

A Pressure Vessel is a container for storing liquid and gas fluid shaped like a cylinder that can produce pressure from outside or inside. Almost all oil and gas industries often use this object to collect and separate water and oil from offshore exploration. This study aims to determine the strength of a Pressure Vessel and determine which is more economical by comparing two types of materials, namely SA-106 Grade B and SA-516-70N, with the same thickness of 12.7 mm. Simulations are carried out on the shell using SolidWorks software to find out the strength of each material. The data used in this study refer to one of the Pressure Vessels from the company with the basic design following ASME section VIII Div.1 standard 2007, document name "Cartridge Filter C027-S-U13000-01 A / B" and document number 6522 -XXX-C027-ISGP-U40300-MX-4018-00XXX with a design pressure of 10 bar, a design temperature of 121 ° C, an inner diameter of 444.5 mm, a corrosion factor of 3 mm. From the calculations and simulations that have been carried out, the values ​​obtained from the maximum pressure on the SA-516-70N material are 34.10 Bar, and the SA-106 Grade B material is 16.90 Bar. The voltage received from the pressure vessel is based on the analysis of the SolidWorks software with the same value for both materials at 1758 psi / 121 Bar. This study also proved that SA-106 Grade B material is far more economical, with an estimated budget of Rp6,531,951 for one 10m long pipe.

Abstract

The Support Structure is a part of the structure that provides rigidity and strength and supports the weight of the load above it. The initial design in this study uses CAD which is then converted to SolidWorks 2019 for simulation. The weight of the load generated for testing the support structure comes from the weight of the module construction above it of 30,925 kg, assumed to be a static load. The material that is part of the support structure in this study is S355J0-type structural steel with a yield strength value of 275 N/mm2. Stress testing shows that the maximum stress is 198 N/mm2 so it can be categorized as safe because x < the yield strength value. Strain testing shows a maximum value of 5.260 × 10-4, while the maximum displacement is 1.168 mm. The factor of safety testing with simulation showed a result of 1.4

Abstract

In shipbuilding, various stages of surveys are conducted when a vessel is declared fit for operation, encompassing annual surveys, intermediate surveys, and special/extension surveys. During these surveys, commonly encountered issues include corrosion and reduction in plate thickness associated with the ship's age and year of construction. In cases of significant thickness reduction, replating procedures are implemented. The examination of plate thickness involves ultrasonic testing utilizing the Cygnus Ultrasonic Gauge, with prior visual inspections performed on each plate section. When inspections reveal considerable thickness reduction and indications of corrosion during visual tests, such instances are evident in areas like the forepeak and deep tank. Substantial thickness reduction is noted on both the port and starboard sides, covering a dimension of 1,200 mm × 400 mm along each plate line, employing standard 12 mm thickness material. Test results are obtained for plate lines numbered 1 to 4 on the port and starboard sides of the Forepeak Tank area, as well as plate lines numbered 1 to 3 on the port side and plate lines numbered 1 to 4 on the starboard side within the Deep Tank region.

Abstract

Molding is a process utilized by industries to shape plastic products. One of the plastic molding processes involves injection molding. Injection molding is a procedure where plastic pellets are placed into a hopper or channel and subsequently fed into a barrel. The injection is propelled by a screw mechanism through a machine nozzle and a sprue bushing enters the mold cavity. All of this occurs within a closed mold. A flashing defect in a product refers to an excess material flaw located at the product's edges. To identify the causes of flashing defects in shaving tools, a fishbone diagram is employed, categorizing factors into five: machine factors, material factors, method factors, human factors, and mold factors. The identification results show that flashing defects in shaving tools are primarily attributed to mold factors, where 37 cavities exhibit flashing defects.

Abstract

The hydroponic pilot project in the Batam State Polytechnic area was motivated by problems with economic conditions and declining health conditions during the Covid-19 pandemic. This project is expected to support the "growing your own food movement" in an effort to reduce unemployment, increase food security and a healthy lifestyle. The hydroponic method was chosen because it is very easy to do and does not require a large area of "‹"‹land. In this community service activity, a hydroponic plant building framework will be made as a prototype of an efficient and efficient hydroponic building so that it can be used by the wider community. This activity is also useful for applying design knowledge as one of the PbL activities carried out by CAD, CNC, CAM, and Fabrication Engineering courses in the Mechanical Engineering Department, so that it can become an arena for higher education participation to support people's lives. The method of implementing this community service activity is to make observations to find a suitable area to build a hydroponic plant house, then the results of the observations are poured in the form of a design by utilizing software so that the materials needed and the shape of the framework that is built can be known. The last activity is making a hydroponic plant place. This activity is planned to be carried out from April to November 2021. Based on the results of the evaluation of the service program questionnaire for product distribution, it is known that the majority of respondents are satisfied with the products produced.
