Abstract

The Mobile Floating Structure (MFS) is an innovative floating wind turbine concept that utilizes a catamaran hull design to enhance mobility and operational efficiency. Unlike stationary platforms, the MFS can relocate to areas with higher wind energy density, making it a promising solution for optimizing wind energy harvesting in offshore environments. This study focuses on the preliminary design and energy production of the MFS. Maxsurf is used to analyze hydrostatics and assess the hydrodynamic performance of the MFS hull after the dimension of the MFS is determine with key considerations including rotor diameter and the weight of the wind turbine. Furthermore, four wind turbines are installed in the MFS. Those aspect were integrated into the design process to ensure realistic operational adaptability. As result. the resulting dimensions of the MFS were determined utilizing Maxsurf. Moreover, different with the previous study that use satellite data, the present study employs reanalysis data to estimate the energy density and power production of MFS. the energy density map is also produced in the present study to determine the monthly location of the MFS. The energy production of the MFS with four turbines has been calculated, and the energy production map is also drawn. Finally, the energy production of the MFS in the chosen location has also been estimated. The energy production map can be utilized to develop MFS in other location.

Abstract

Setiap kapal sebelum dioperasikan wajib dilakukan pengukuran untuk menentukan ukuran panjang, lebar, dalam dan tonase kapal sesuai dengan metode pengukuran kapal yang telah diatur dalam PM Perhubungan Nomor 8 Tahun 2013 tentang Pengukuran Kapal. Salah satu ukuran utama kapal yang harus dihitung pada kapal yang dibuat adalah Gross Tonage (GT) yang berfungsi untuk pendataan kapal dan system administrasi yang berkaitan dengan pajak, sewa pelabuhan, asuransi dan docking space. Melalui program pengabdian ini kami bermaksud untuk mengadakan pelatihan pengukuran kapasitas Gross Tonage pada kapal nelayan traditional. Manfaat yang diperoleh dari program pelatihan ini adalah peningkatan kemampuan mitra sebagai pemilik kapal dan masyarakat untuk mampu menghitung tonase kapal yang dimiliki. Mitra yang terlibat dalam kegiatan ini adalah nelayan pada Kelompok Usaha Bersama (KUB). Mitra Nelayan Muara Baru di Muara Tunan, Tanjung Tengah, Penajam Paser Utara. Harapannya, para nelayan yang merupakan anggota dari kelompok nelayan tersebut melalui kegiatan ini akan dapat bersinergi dengan pemerintah daerah berkaitan dengan sertifikasi kesempurnaan kapal. Program-program untuk pengembangan kualitas dan peningkatan produksi kapal tradisional dapat berjalan seiring yaitu dengan memanfaatkan data ukuran utama kapal untuk analisa unjuk kerja kapal tradisional.

Abstract

Challenges in procuring wood as the primary material for ships have led to a decline in overall quality. Meeting the demands of shipbuilding often involves neglecting consideration for the quality and characteristics of construction materials. Additionally, the shipbuilding process commonly overlooks technical and operational aspects associated with construction specifications. Ship damages frequently result from the selection of wood types, sizes, and ages that do not meet construction criteria or fall below the standards for achieving optimal construction. Many ship constructions are identified that fail to meet the requirements for ensuring the safety and security of the crew, ship, and cargo during operations. This research aims to numerically assess the transverse strength of fishing vessels operating in Penajam Paser Utara using Ansys software. Survey results indicate an average size of fishing boats in this area as 10 – 20  meters in length. 2.6 - 3.5 meters in width, and 1.6 – 2.5 meters in height. The stress analysis results from Ansys Workbench were recorded at 2.3402 MPa
