Abstract

The Natuna Sea, a critical fishery zone for Indonesia, is persistently threatened by Illegal, Unreported, and Unregulated (IUU) fishing activities. Effective maritime law enforcement in this region demands patrol vessels that combine exceptional seakeeping stability with high-speed pursuit capabilities. This study responds to this requirement through the design and hydrodynamic evaluation of a novel 23-meter asymmetric catamaran hull form specifically optimized for patrol missions in Natuna waters. The vessel's intact stability was rigorously assessed according to the IMO Intact Stability Code (A.749(18)) for full and partial load conditions, while its resistance characteristics were analyzed across a speed range of 12 to 40 knots using the Savitsky Planning method. The results demonstrate that the proposed design significantly exceeds regulatory safety standards, with stability safety margins of 500-800% above the IMO minimum. The area under the righting lever (GZ) curve (0-30°) was calculated as 21.48 m·deg, significantly higher than the required 3.15 m·deg, indicating robust energy absorption in rough seas. At the maximum operational speed of 40 knots, the total resistance was 110.11 kN, corresponding to a required brake horsepower of 7,224 HP, which can be feasibly delivered by a twin-engine configuration. The design also incorporates a step water deflector, reducing spray resistance by approximately 15%. This study concludes that the asymmetric catamaran configuration presents a technically viable and superior alternative to conventional monohulls, offering an optimal blend of high-speed performance, exceptional stability, and enhanced fuel efficiency for extended patrols in the challenging Natuna Sea environment.

Özet

Endonezya için hayati bir balıkçılık bölgesi olan Natuna Denizi, yasa dışı, kayıt dışı ve düzensiz (IUU) balıkçılık faaliyetlerinden sürekli tehdit altındadır. Bu bölgede etkili denizcilik hukuku uygulaması, olağanüstü denizde tutunma stabilitesi ile yüksek hızda takip kabiliyetini bir araya getiren devriye gemileri gerektirmektedir. Bu çalışma, Natuna sularındaki devriye görevleri için özel olarak optimize edilmiş, 23 metrelik yeni bir asimetrik katamaran gövde formunun tasarımı ve hidrodinamik değerlendirmesi yoluyla bu gereksinime yanıt vermektedir. Geminin sağlam stabilitesi, tam ve kısmi yük koşulları için IMO Sağlam Stabilite Kodu (A.749(18))'na göre titizlikle değerlendirilirken, direnç karakteristikleri Savitsky Planlama yöntemi kullanılarak 12 ila 40 knot arasındaki bir hız aralığında analiz edilmiştir. Sonuçlar, önerilen tasarımın düzenleyici güvenlik standartlarını fazlasıyla aştığını, IMO asgari değerlerinin %500-800 üzerinde stabilite güvenlik marjlarına sahip olduğunu göstermektedir. Doğrultma kolu (GZ) eğrisi altındaki alan (0-30°) 21.48 m·derece olarak hesaplanmış olup, bu değer gerekli olan 3.15 m·derecelik değeri önemli ölçüde aşmakta ve fırtınalı denizlerde sağlam bir enerji absorpsiyon kapasitesine işaret etmektedir. Maksimum operasyonel hız olan 40 knot'ta toplam direnç 110.11 kN olup, bu da 7,224 HP'lik bir gerekli fren beygir gücüne karşılık gelmekte ve bu güç ikiz motor konfigürasyonu ile sağlanabilmektedir. Tasarım ayrıca, püskürtme direncini yaklaşık %15 oranında azaltan bir basamaklı su saptırıcı içermektedir. Bu çalışma, asimetrik katamaran konfigürasyonunun, zorlu Natuna Denizi ortamında uzun devriyeler için yüksek hız performansı, olağanüstü stabilite ve gelişmiş yakıt verimliliğinin optimal bir karışımını sunarak, geleneksel tek gövdeli gemilere kıyasla teknik olarak uygulanabilir ve üstün bir alternatif olduğu sonucuna varmaktadır.
