【 摘 要 】

Natuna Sea is one economy strategic outer area, which connected into archipelagic international sea lanes (ALKI I). The research area is in that area using two specifics observation Naval base stations: (South) Dabo Singkep and (North) Ranai. Wave characteristics are needed to be conducting a secure the naval operation cruises. The statistical analysis is carried out using 2016 ECMWF 6 hourly datasets with 14 km grid spatial resolution. The variable of significant wave height (SWH), period and wave direction has been analyzed by monthly-yearly averages. Maximum SWH during rough wave period is range of 5.1 m (January) and 2.3 m (February). The minimum SWH is range of 0.2 m (April) and 0.1 m (July). The predominantly wave direction at Dabo Singkep is coming from southeast (135°; mostly in July), and at Ranai is coming from the northeast (45°; mostly in January). During the rough wave period, it is highly recommended using the KRI warship with length > 82 m and high hull > 2.3 m for surveillance cruise in the southern part of Natuna Sea. While in the northern part, would be needed KRI with a length > 146 m, and the high hull > 4.8 m.
