Abstract
The conversion of Landing Craft Tank into Livestock Carrier as an alternative solution was conducted by performing technical and economic assessments. The conversion analysis of LCT vessels to Livestock Carrier was achieved by performing layout rearrangement, stability test, seakeeping, and resistance test to measure the technical change occurring due to the modification. The economic added-value analysis was conducted by calculating the payback period to determine the estimated time needed to recover the cost of an investment. The result showed that the conversion of LCT ships has a good technical assessment. The intact and damage stability performance qualifies the standard criteria given by the IMO standard. The motion result qualifies the standard according to the type of vessel in terms of heave, pitch, and roll motions. Moreover, the resistance of the Livestock Carrier is reduced due to a decrease in displacement and draft. In terms of economic assessment, the Livestock Carrier conversion project qualifies for investment projects and improves the use-value and economy of a business segment.
Highlights
The Landing Craft Tank (LCT) ship was designed to carry combat and heavy equipment during World War II
To comprehend the safety aspect based on the decision of the Directorate General of Sea Transportation of Indonesia, LCT ships are forbidden to be used as ferry transportation
The ship conversion is evaluated by conducting technical measurements, including redesigning the ship layout, measuring the ship's structural weight, and considering the ship’s performances numerically, including resistance test, stability, and ship motion
