Abstract

Diantara fasilitas galangan yang ada di PT.Dok dan Perkapalan Surabaya penggunaan floating crane menunjukkan efektifitas produksi yang nyata. lni disebabkan karena terbatasnya jangkauan dan kapasitas crane darat untuk memmjang kegiatan galangan. Floating crane di PT.Dok dan Perkapalan Surabaya berjungsi terutama untuk pengangkatan material atau blok blok untuk kegiatan ship repairing maupun ship bui /ding. Saat ini kapasitas floating crane yang dimiliki PT.Dok dan Perkapalan Surabaya maksimum 30 ton dengan tipe fix crane, non-self propelled barge. Kondisi tersebut mengurangi efisiensi kerja galangan terutama untuk kebutuhan pengangkatan material atau blok-blok /ebih dari 30 ton. 0/eh karena itu kapasitas floating crane yang lebih besar diper/ukan sehingga volume pemindahan material atau blok blok menjadi /ebih cepat. Dalam tugas akhir ini dilakukan perancangan floating crane sesuai dengan kebutuhan PT.Dok dan Perkapalan Surabaya diuraikan. Crane yang dipakai direncanakan memiliki kapasitas angkat 100 ton. tipe revolved crane 360° dan tipe barge-nya yaitu self propelled barge. Proses perancangan dimulai dengan mencari ukuran utama barge. Ukuran utama barge didapatkan dari barge pembanding. Adapun ukuran utama yang perlu diperhatikan adalah LoalLpp, B, H, T, dan kapasitas daya angkat. Selanjutnya dari data tersebut dilakukan proses optimisasi yang meliputi perhitungan tahanan, propu/si, BHP mesin induk, intact stability, trim dan estimasi harga pembangunan serta biaya operasional tahun pertama. Fungsi obyektif dari proses ini adalah meminimalkan biaya pembangunan dan biaya operasional tahun pertama. Dari hasil proses ini ukuran utama optimal yang didapatkan ada/ah Lpp = 42.672 m, B = 23.000 m, H = 3.369 m, T = 2.081, Vs = 5 knot. Berdasarkan ukuran utama optimal ini, gambar rencana garis dan rencana umum floating crane disajikan dan diana/isis.

The use of a floating crane in PTDok and perkapalan Surabaya between shipyard facilities gives the production efectifity. The reason for this is that the capacity and reach of existing mobile and lifting cranes are Umited and not sufficient to support planned shipyard activities. The floating crane in PTDok and Perkapalan Surabaya has a function especially to lift building blocks or material for ship repairing and ship building. Currently, the maximum capacity of the floating crane in PTDok and Perkapalan Surabaya is 30 ton with the type of.fix crane, non-self propelled barge, which is ever than the intended capacity, that is 100 ton. Therefore, the larger capacity of floating crane is needed, thus moving blocks or material faster. In thisfinal project, the design of a floating crane suited to the requirement of PTDok and Perkapalan Surabaya is presented . The crane to be planned has a lifting capacity of 100 ton, with the type qf 360° revolved crane and se!fpropelled barge. The design process starts with searching principal dimensions of the barge, which include Loa or Lpp, B, H, T and the lifting capacity. Then from these data, the optimization process is carried out which considerd the resistance, horse power of main engine, intact stability, transverse stability and estimation of ship building cost and first year operating cost. The objective function of this process is to minimize these costs. The optimum principal dimensions resulting from this optimization process are Lpp=42.672 m, B=23.000 m, H 3.369 m, T=2.081 m and Vs=5 knots. Using these dimensions, Lines Plan and General Arrangement are then drawn and analyzed.
