Numerical Analysis of Mooring Buoy for Securing N219A Aircraft in The Anchorage Area

Abstract

The development of Indonesia's N219 aircraft in recent years has been carried out on a significant scale. Likewise, developing an amphibious version known as the N219A aircraft continued. Considering that Indonesia is an archipelagic country that has potential in many sectors, such as marine tourism, the N219A aircraft is designed to be able to land on the water. Consequently, facilities are needed for the aircraft to be secured safely. The analysis of determining the configuration of the length of the anchor line on the mooring buoy to secure the N219A aircraft was carried out by varying the line length of the rope to 50 meters, 60 meters, and 70 meters by FAA recommendations. Based on the numerical calculation, the anchor line configuration with a length of 60 meters has maximum tension with allowable criteria according to API RP 2SK in intact and damaged conditions. The anchor line configuration also has a maximum offset value that is shorter than other configurations. Therefore, the result obtained from the analysis of the N219A aircraft's anchor spacing for the sea conditions of Gili Iyang, Sumenep, Madura, and East Java is 118.18 meters.
