Ship to Ship Transhipment Network Optimization


Ship to Ship Transhipment Network Optimization
Gede Wahyu Yoga Dana


Ship to ship (STS) is type of ship operation where cargo is transferred from mother vessel to feeder vessel. This operation occur due to several contrains, one of those is draft contraint, channel draft or port draft. Mother vessel load the cargo from supply port then sailing to selected location where STS operation is allowed.  After that, the cargo is transferred from mother vessel to several feeder vessels then transported to demand ports. The mother vessel which is used,  STS location, and the number of ship to service demand ports and should be determined so that the total transportation cost is minimized. To obtain that, the transhipment network model is developed using mix integer linear programming (MILP). Then, the case study in bulk shipping carrier is used to validate model with real STS transhipment problem.
