Perancangan Rescue Boat Berbahan Komposit untuk Penyelamatan Bencana Banjir
According to BNPB, floods are the most common natural disaster in Indonesia in 2022.
Therefore, sandwich composite flood rescue boat is needed. The main dimensions of this rescue boat is
obtained from trial and error method resulting in L:6m, B:2 m, H:1 m, T:0.25m and Vs:13 knots. After
designing two hull models with the same main size, resistance analysis is carried out using Maxsurf
Resistance software. Based on this analysis, the pram hull model was chosen because the resistance of
the pram hull model is smaller at 3 knots and just need 85 HP engine. Meanwhile the boxy hull model
has a resistance at 5.1 knots and need 150 HP engine. The construction thickness that meets the
thickness requirements of the sandwich composite, the DWT is 0.630 tons and the LWT is 0.562 tons.
The results of the stability calculation with reference to the IMO A.749(18) regulation, on the full
loadcase and empty loadcase have met the requirements. Based on the calculations, the estimated cost
of building a rescue boat is IDR 136,016,142.00. The design of the 3D rescue boat model was made
using Sketch-Up software and made a miniature rescue boat.
