Abstract
Kondisi cuaca dan gelombang tinggi berkontribusi signifikan terhadap kecelakaan
kapal. Hal tersebut juga menjadi salah satu faktor penghambat operasi SAR (Search And
Rescue) untuk melakukan pertolongan pada korban kecelakaan kapal. Untuk menunjang proses
operasi SAR, BASARNAS memerlukan sebuah desain self-righting rescue boat yang mampu
berakselerasi tinggi dan dapat menembus berbagai kondisi laut yang ekstrem. Dengan konsep
stabilitas self-righting ini, memungkinkan rescue boat tetap dapat beroperasi pada perairan
yang memiliki ketinggian gelombang yang cukup besar karena kapal akan dapat kembali
keposisi semula walaupun kapal mengalami oleng hingga sudut 1800. Payload yang digunakan
adalah kapasitas crew dan penumpang dari self-righting rescue boat. Ukuran utama awal kapal
ditentukan dengan menggunakan metode Geosim Prosedure. Kemudian dilakukan perhitungan
teknis yang meliputi koefisien bentuk lambung, hambatan, berat dan titik berat kapal,
freeboard, trim, stabilitas self-righting, dan MSI (Motion Sickness Incidence). Ukuran utama
yang memenuhi kriteria teknis dan regulasi adalah LoA: 14.32 m, Lpp: 13.6 m, B: 4.0 m, H:
2.3 m, dan T: 0.8 m. Untuk metode self-righting yang digunakan adalah inherent self-righting.
Metode ini diperoleh dengan cara membesarkan volume bangunan atas rescue boat dengan
variasi lebar bangunan atas. Dari analisis MSI dengan parameter ISO 2631, rescue boat dinilai
nyaman untuk beroperasi pada ketinggian gelombang 2.5 m hingga 4 m (sea state 5) atas
pertimbangan 2 jam pelayaran dan dinilai nyaman untuk beroperasi pada ketinggian gelombang
4 m hingga 6 m (sea state 6) atas pertimbangn 30 menit pelayaran. Estimasi biaya pembangunan
self-righting rescue boat adalah sebesar Rp 2,619,236,881.22.
============================================================
Weather and high wave conditions contribute significantly to ship accidents. It is also
one of the inhibiting factors for search and rescue operations to help victims of ship accidents.
To support the SAR operation process, BASARNAS requires a self-righting rescue boat design
that can accelerate high and can penetrate various extreme sea conditions. With this selfrighting
stability concept, it allows rescue boats to operate in waters that have a fairly large
wave height because the ship will be able to return to its original position even though the ship
undergoes shaking up to of 1800. The payload used is crew and passenger capacity of selfrighting
rescue boat. The initial main size of the ship is determined using the Geosim Procedure
method. Then a technical calculation is carried out which includes the hull shape coefficient,
resistance, weight and center of weight, freeboard, trim, self-righting stability, and MSI (Motion
Sickness Incidence). The main dimension that comply the technical and regulatory criteria is
LoA: 14.32 m, Lpp: 13.6 m, B: 4.0 m, H: 2.3 m, and T: 0.8 m. The self-righting method used
is inherent self-righting. This method is obtained by raising the volume of the rescue boat
superstrucure with the variation of the superstructure width. From the MSI analysis with ISO
2631 parameters, a rescue boat is considered comfortable to operate at a wave height of 2.5 m
to 4 m (sea state 5) on the consideration of 2 hours of voyage and considered comfortable to
operate at a wave height of 4 m to 6 m (sea state 6) on the consideration of 30 minutes of
voyage. The estimated cost of building a self-righting rescue boat is Rp. 2,619,236,881.22.
