Abstract

The high demand for building the vessels and ojfshore structure as jackup, such as platform, and submersible rig causing shipbuilding industry demanded to do some inovivation in order to make the ship building process to be more e'mzctive and e17icient. One of the key przocess on ship building is Block's Erection. This research carried out to include the design and analysis to create a tool fbr block erection which capable to boost the e17‘ectiveness and e17iciency on production of shipbuilding. The angular contact ball bearing is the Tool which created and proven very e,0‘ective to use on the process of erection block ship DRU 3 PT. Karimun Sembawang Shipyard. The research is applying descriftive analytic methode which use to analyse the compressive stress and shear strength and proved capable to receive the maximum load as planned. By using material grade AH 36 with tensile strength up to 285.000 Psi, proven much higher than total load applied to them. The results of the study showed that the Angular contact ball bearing capable to work on big load and also can move in all directions with will boost process the ship production significantly. Shipyard should be consider to develop the thrust ball bearing technology as a tool for block erection process.

Abstract

The calculatton of the draft survey is a highly anticipated result as a reference of business transacttons and as a reference to the determination of tax payments to the state. Fast in terms of time and precise calculation accuracy becomes a demand in business services especially in international business. Given the delay impacted the loss of a fine to be paid by the recipient of goods for being late in the process of loading or known as Demurraage. The problem raised in this research is how to apply the calculation of the optimal draft survey with the speed of time and accuracy of calculation. The research method used in this research is quantitative analysis by calculate of cargolood/ verify the calculation of the number of vessels betweet the conventional draft survey method and the method of draft survey microsoft excel which refers to the data of the ship that has been verified by the PT. Surveyor Indonesia. The results obtained from this research is the calculation by the method of draft survey microsoft excel has a high level of accuracy because the chances of error due to human error is smaller that the calculation by manual. It consume also more effective time compared to manual methods (more time efficient).

Abstract

Lifting Arrangement is a platform for the process of using cranes, in this final task discussing the operation of a platform located in the main deck conducted in Saipem Taqa Al-Rushaid Yard Company. The analysis of this research is focused on the Penganangkatan tool because it has different types and types. The size of the Platform has a length of 34714 m, width of 18700 m and weight 221.51 tonnes. The most critical part of this lifting process is the angle determination for each wire sling because the crane is used for different types and types. The Minimum Angel used in the process of the Pengkatan this platform for Crane 1 is 69 º, Crane 2 is 69 º, Crane 3 is 71 º and the Crane 4 is 71 º.

Abstract

The pump is a machine for moving fluid. The pump moves fluid from a low pressure place to a place with a higher pressure, to overcome this pressure difference a power is needed. The cooling system is a system that serves to keep the engine temperature in ideal conditions.Seawater cooling pump used on the MV.BAHARI 22 ship, experienced a problem of decreased suction power analyzed using quantitative research methods in which research uses data taken directly on the ship. Then the analysis of this study uses a predetermined formula. Research findings and analyzed data are head loss which includes static head, head pressure, head speed, head major loss, head minor loss. The decrease in the pressure of the sea water coolant pump on the ship is caused by the total head of the system which exceeds the pump head where the head of the system according to the calculation is 61 m, while the maximum head of the pump is only 55 m so that the cavitation in the pump is ensured which causes impeller damage and damages the house the snail This can be proven from the calculation results where the NPSHr value = 5.49 meters far exceeds the NPSHa value which is only 2.52 m.

Abstract

The use of electrical energy in shipping is very important its role as a supporting factor for the smooth operation of the ship itself, for that it needs to be made a very mature design so that the system is able to work effectively and efficiently and be able to overcome the disturbances that occur at any time. Comfort during the process of the operation of the ship and every active'ltas certainly can not be separated from a good lighting system. the main goals and objectives to be achieved in this lighting installation system is that the amount of lighting needed in the operation of the ship can be adequate, sufficient and efficient in its use by not ignoring the safety system both for humans and equipment.

Abstract

On the suction ship produced by PT. Timah (Persero) Tbk applies a lighting system using standards from the 2012 Minister of Health Decree regarding the level of lighting in the work environment. With this standard, it is expected that each manganese lighting will function properly according to the active needs of the task. The lamp used for lighting in each room is Philips TL-D 36 Watt with Pacific TCW097 type, so the lamp can last a long time because it is protected from dust which can reduce the quality of the lamp. The results of research on the use of energy, in this case electricity in shipping plays a very important role for the needs of manganese lighting. Therefore the lighting system of a room on the ship must be planned well taking into account the energy conservation efforts that can be done

Abstract

Dalam perencanaan pemilihan ukuran utama kapal (principle dimension) dibutuhkan pengambilan keputusan sesuai dengan kriteria yang telah ditentukan. Pengambilan keputusan yang tepat dan sesuai dengan kriteria yang dibutuhkan akan menjadi rumit apabila dihadapkan pada beberapa kriteria yang saling berhubungan dan harus terpenuhi. Oleh sebab itu digunakanlah logika fuzzy guna membantu dalam penentuan pengambilan keputusan. Dalam perencanaan pemilihan ukuran utama kapal barang pada jurnal ini diberikan beberapa batasan yaitu tinggi sarat maksimal kapal yaitu 6 meter, panjang keseluruhan kapal sekitar 100 meter, dan berat mati kapal kira – kira 3000 ton dan 5000 ton. Setelah dilakukan analisa menggunakan logika fuzzy terhadap data kapal-kapal yang telah dikumpulkam, didapatkan hasil yang menunjukan kapal nomor 16 memiliki nilai keanggotaan satu sehingga masuk dalam kriteria sangat memenuhi.
