Strength Analysis of Towing Hook Support Structure on TB. Khatulistiwa 01

Towing hook is one of the important components a tugboat. Its function to tow various types ships, namely containers, tanker and even barges. This activity affects undergo failure crack, especially support structure hook. Earlier research has analyzed stress characteristics, fatigue maximum stress, factor safety aimed both at whole profile tug. The aim determine value in brought by tensile load transferred from towing analysis done using finite element method Altair Hyper Works 2019. Structural strength 2 loading conditions, lightweight barge full barge. Two different approaches are used for comparison. first approach resistance, second utilizing tug horse-power speed ratio. Maximum acquired conditions 118.64 MPa; 121.80 230.90 329.86 MPa respectively. measured criteria, BKI permissible criterion Material Strength criterion. Results factors based on 1.644; 1.601; 0.845; 0.591. According Strength, 3.371; 3.284; 1.732; 1.212.
