Abstract

Crane vessel adalah sebuah bangunan apung yang dilengkapi dengan fasilitas akomodasi dan satu atau lebih crane untuk melakukan pekerjaan dilapangan. Crane vessel terus dikembangkan agar dapat mengangkat struktur yang besar dan juga dapat beroperasi dengan aman pada kondisi lingkungan tertentu. Pekerjaan yang biasa dilakukan oleh crane vessel adalah mengangkat beban berat maupun ringan dari darat ke kapal, dari kapal ke darat, dari kapal ke laut, dari laut ke kapal, ataupun dari kapal ke kapal. Proses pemindahan muatan yang dilakukan oleh crane vessel biasa disebut proses lifting. Crane vessel dalam melakukan pekerjaannya dibatasi oleh kriteria-kriteria tertentu dengan alasan keselamatan. Salah satunya adalah kriteria yang membatasi gerak heave pada ujung crane boom dan gerak roll dan pitch pada crane vessel. Pada penelitian tugas akhir ini dilakukan studi eksperimen dan analisis numeris operabilitas crane pada crane vessel berlambung catamaran. Eksperimen dilakukan di Balai Teknologi Hidrodinamika BPPT dan analisis numeris menggunakan bantuan perangkat lunak MOSES. Sesuai kriteria yang digunakan yaitu Operational Limitations of Offshore Crane Vessels, crane pada floating crane catamaran memiliki operabilitas paling tinggi saat vessel heading 0o terhadap arah datang gelombang yaitu hingga Hs 1.45 m. ================================================================================================================== Crane vessel is a floating structure equipped with accommodation facilities and one or more cranes to do work in the field. Crane vessel continue to be developed so that they can lift large structures and can also operate safely in certain environmental conditions. The work that is usually done by crane vessel is to lift heavy or light loads from land to ship, from ship to land, from ship to sea, from sea to ship, or from ship to ship. The process of moving loads carried out by a crane vessel is usually called the lifting process. In carrying out its work, a crane vessel is limited by certain criteria for safety reasons. One of them is the criterion that limits the heave motion at the end of the crane boom and roll and pitch motion of the crane vessel. In this final project, an experimental study and numerical analysis of crane operability were carried out on catamaran hulled crane vessel. Experiments were carried out at the Balai Teknologi Hidrodinamika BPPT and numerical analysis using the MOSES software. According to the criteria used, namely Operational Limitations of Offshore Crane Vessels, cranes on floating crane catamaran have the highest operability when the vessel heading is 0o to the direction of the incoming waves, which is up to Hs 1.45 m.
