Abstract
Sistem konstruksi kapal pada umumnya dibedakan menjadi tiga jenis yaitu sistem konstruksi melintang, sistem konstruksi membujur dan sistem konstruksi kombinasi. Pada kapal tanker yang kontruksinya merupakan kontruksi tipe membujur pada bagian deck diperkuat oleh pembujur geladak (deck longitudinal). Penulis melakukan inovasi dengan mengubah deck longitudinal dan deck floor menjadi corrugated floor dibagian deck yang berfungsi sebagai pemberi kekuatan pembujur kapal. Adanya perubahan pada kontruksi deck akan mempengaruhi kekuatan kapal sehingga perhitungan kekuatan kontruksi perlu dilakukan untuk mengetahui perbedaan antara kontruksi keduanya. Dalam kajian analisa akan dibahas mengenai tiga yaitu besarnya nilai perbandingan masing beban yang diterima, displacement, modulus dari konstruksi corrugated floor. Kajian kedua perbandingan berat konstruksi deck longitudinal dan corrugated floor, serta kajian yang terakhir yaitu tentang efisiensi corrugated floor tersebut berdasarkan keuntungan dan kerugian masing-masing. Dalam melakukan analisa kekuatan atau pengujian kekuatan kontruksi maka dilakukan simulasi menggunakan program solidwork. Dari hasil analisa kekuatan konstruksi Deck Longitudinal Model & Corrugated Deck Model dengan beban statis dan variasi nilai beban dinamis dari nilai persentase beban statis maka diperoleh nilai Pembebanan Statis Hasil analisa konstruksi Deck Longitudinal Model Max. Stress=183.999.726 N/m2, Displacement=1.93181 mm, Strain= 0.0113813, FOS=1.36,Hasil analisa konstruksi Corrugated Deck Model :Max. Stress =2.287.317,8 N/m2, Displacement= 0.260966 mm, Strain =0.00161214 FOS= 104.889. Pembebanan DinamisHasil analisa konstruksi diambil sampel nilai beban dinamis yang paling tinggi pada kedua konstruksi. Hasil analisa konstruksi Deck Longitudinal Model Max. Stress=1.64245 x108 N/m2, Displacement=198.432 mm, Strain=0.0065362, Hasil analisa konstruksi Corrugated Deck Model Max. Stress=433891 N/m2, Displacement=0.376273 mm, Strain=5.26406 x 10-6. Untuk analisa hasil berat konstruksi diperoleh b nilai berat konstruksi Corrugated Deck Model sebesar 61971 kg untuk dengan ketebalan pelat 13 mm dan volume konstruksi 7.894 m3 dan berat konstruksi Deck Longitudinal Model sebesar 72136.2 kg untuk dengan ketebalan pelat 15 mm dan volume konstruksi 9.18933 m3.
================================================================
The ship construction system is generally divided into three type : transverse construction system, longitudinal construction system and combination construction system. In tankers whose construction is a longitudinal type construction on the deck portion is reinforced by deck length deck longitudinal decks. The author innovated by changing the deck longitudinal and deck floor into corrugated floor section of the deck that serves as a giver of longitudinal force of the ship. Any change in the construction of the deck will affect the strength of the ship so that the calculation of the strength of construction should be done to determine the difference between the two constructions. In the analysis study will be discussed about the three values of the ratio of each load received, displacement, modulus of corrugated floor construction. The second study comparing the weight of longitudinal and corrugated floor deck construction, and the last review is about the corrugated floor efficiency based on the advantages and disadvantages of each. In performing strength analysis or strength of construction test, simulation is done using solidwork program. From result of analysis of construction strength Deck Longitudinal Model & Corrugated Deck Model with static load and variation of dynamic load value from value of static load percentage hence obtained value of static loading Result of construction analysis of Deck Longitudinal Model Max. Stress = 183.999.726 N / m2, Displacement = 1.93181 mm, Strain = 0.0113813, FOS = 1.36, Result of construction analysis Corrugated Deck Model: Max. Stress = 2.287.317,8 N / m2, Displacement = 0.260966 mm, Strain = 0.00161214 FOS = 104.889. Dynamic loading The result of construction analysis is taken by sampling the highest dynamic load value in both constructions. Result of construction analysis of Deck Longitudinal Model Max. Stress = 1.64245 x108 N / m2, Displacement = 198.432 mm, Strain = 0.0065362, Results of construction analysis Corrugated Deck Model Max. Stress = 433891 N / m2, Displacement = 0.376273 mm, Strain = 5.26406 x 10-6. For the result of weight analysis, the weight value of construction of Corrugated Deck Model is 61971 kg for 13 mm thickness and 7,894 m3 of construction volume and construction weight of Longitudinal Deck Model 72136.2 kg for 15 mm thickness and construction volume 9.18933 m3.
