Export version of the 63 meters FMPV Trimaran (photo : Navy Recognition)

The Fast Missile Patrol Vessel (FMPV) Trimaran was designed by North Sea Boats, an Indonesia based shipyard, with input from New Zealand and Swedish engineers as well as the Indonesian Navy. The vessel employs a modern “Wave Piercing” trimaran design and some "stealth" characteristics.

An export version of the 63 meters FMPV Trimaran is available. North Sea Boats partnered with SAAB for this version, as a consequence most weapons and sub-systems are provided by the Swedish Defence group as shown in the picture below which was displayed on SAAB booth during Indodefence 2012.

FMPV Trimaran in export configuration would come with:

» Saab RBS15 Mk3 anti-ship missiles

» BAE Systems Bofors 40Mk4 40mm main gun

» Saab Sea Giraffe LT radar

» Saab CEROS 200 radar and optronic tracking system

» Saab 9LV Combat management system

“Wave Piercing” trimaran design: This allows the vessel to cut-through waves rather than rise up and over them, and the increased beam provides inherent stability. This combination of features reduces both pitching and rolling, creating a stable weapons platform, and enabling the vessel to comfortably and safely maintain higher average speeds in adverse conditions.

The FMPV has “Stealth” design characteristics, and incorporate features that minimise detection by reducing Radar, Infra-Red, Acoustic and Magnetic signatures. Stealth properties are further improved as there are no reverse-angle bow overhangs to reflect radar signals, as seen on conventional hull forms. Weaponry, including missiles and naval guns, and the ships 11 m high-speed RHIB, are discreetly concealed or shaped to meld into the superstructure profile.

Construction is from strong and highly durable, lightweight composite carbon fibre sandwich, utilising vinylester modified epoxy resin and the vacuum resin infusion process. Thus ensuring improved fuel efficiency, and reduced operational, maintenance, and life cycle costs.

KRI Klewang-625 sepanjang 63 meter, berbahan dasar vinylester carbon fiber (infused), menggunakan teknologi maju di bidang pembuatan kapal perang antara lain kemampuan tidak terdeteksi oleh radar, tidak mengandung unsur magnet, serta tingkat deteksi panas dan suara yang rendah. (photo : fallenpx)

Surabaya(ANTARA News) - TNI AL menyiapkan personel yang akan mengawaki kapal canggih terbaru KRI Klewang-625 lewat pelatihan di galangan PT Lundin Industry Invest, Kabupaten Banyuwangi, Jawa Timur. Ini adalah kapal berlunas tiga (trimaran) bahan komposit sepanjang 65 meter dengan teknologi rancang bangun terkini.

Masalahnya tinggal melengkapi persenjataan, navigasi, dan sistem komunikasinya sesuai dengan kelasnya. Tanpa itu semua, kecanggihan kapal buatan dalam negeri yang setara dengan kualitas buatan Amerika Serikat itu bisa sia-sia belaka.

Kepala Dinas Penerangan Komando Armada RI Kawasan Timur, Letnan Kolonel Khusus Yayan Sugiana, di Surabaya, Senin, menjelaskan pelatihan itu saat ini sudah berjalan dan akan berakhir pada pertengahan September 2012.

TNI AL pada 31 Agustus lalu meluncurkan kapal cepat rudal jenis trimaran di Selat Bali, Kabupaten Banyuwangi. Meskipun sudah diluncurkan, kapal yang diklaim tidak bisa terdeteksi radar lawan itu masih memerlukan penyempurnaan dan nantinya akan bergabung dalam jajaran Koarmatim.

"Ada33 personel calon awak KRI Klewang-625 yang saat ini ikut pelatihan. Pelatihan ini penting agar personel itu mampu mengawaki kapal canggih itu secara baik," kata Sugiana.

Sementara Komandan Satgas Proyek Pengadaan KCR Trimaran, Kolonel Teknik Heru Sriyanta, diharapkan setelah pelatihan tersebut para pengawak KRI Kelewang-625 dapat mengoperasikan kapal dengan penanganan terbaik.

"Sehingga seluruh peralatan yang ada di kapal dapat dipelihara dengan baik dan dapat memperpanjang usia pakai kapal mejadi lebih lama," katanya. (*)

KRI Klewang 625 (all photos : North Sea Boats)

At 12.00 hours on Friday, the 31st of August, 2012, North Sea Boats Ltd successfully launched one of the most innovative warships in the world into the straits between East Java and Bali, at Banyuwangi, in the Republic of Indonesia.

Measuring 63m in overall length, the vessel will he named KRI Klewang - after a traditional Indonesian single edged sword. It combines a number of existing advanced technologies into a single, unique platform; a wave-piercer trimaran hull form, constructed exclusively of infused vinylester carbon fibre cored sandwich materials for all structural elements, with external "Stealth" geometry and features intended to reduce detection.

The result of a 24 month research, design and development collaboration with New Zealand naval architects, LOMOcean Design Ltd, the ship represents a significant step forward in the use of advanced warship building technologies in countries outside of Europe and the United States.

Offering stability and shallow draft, the vessel is designed for patrolling the littorals. The hull shape is intended to permit high speeds to be maintained and thus maximize crew operational capability in the short, steep seas characteristic of the coastline around the Indonesian Archipelago. The design borrows elements from previous trimarans from the same designer, including the 24m Earthrace (later Ady Gil), holder of the record for the fastest circumnavigation of the globe by a power boat.

The underwater sections have been optimized for extended range at fast patrol speeds; the length, transverse and longitudinal positions and immersion of each of the three hulls have been carefully tailored for least resistance using both slender body analysis and towing tank testing. Powering and propulsion is courtesty of multiple MAN V12 diesel engines, coupled to MJP 550 water jets, located in both the centre hull and each of the two side hulls for maximum propulsive thrust and manoeuverability.

The use of carbon foam sandwich composites on this scale in naval application is unprecedented outside or Scandinavia and is representative of the current state of the art in both maritime composites structural engineering and production technology.

The structural design was subject to third party approval by Germanischer Lloyd in Hamburg, using design and approval methodologies tailored specifically for the unusual geometry of a large, wave-piercing trimaran. The construction medium offers multiple benefits, including reduced weight (laminated carbon fibre has a density nearly half that of aluminium alloys), reduced maintenance (carbon composites cannot corrode and exhibit extremely high fatigue limits), tailorability of radar cross section (true flat panel geometry can be attained due to no distortion during assembly), extremely high geometrical accuracy (permits as-built hull shape to remain faithful to theoretical optimums), nil magnetic signature, reduced thermal and acoustic signatures etc.

Production engineering methodologies were selected and tailored to the local labour environment, with emphasis placed on the use of advanced manufacturing techniques and a combination of excellent training and robust systems guaranteed to offer high part quality, repeatability and geometrical accuracy. The use of infusion technology in particular offers high level of  confidence in the quality and consistency of fiber wet out, high resin to fiber ratios, low void content and excellent bond quality between skins and core as well as at core joints.

Traditionally, achieving high levels of quality in composite construction on a large scale has been problematical without a highly skilled, specialist workforce. The high volume, vacuum infusion systems introduced by North Sea Boats almost completely mitigates such risks and offers high confidence in the integrity of the structures involved. The flat, facetted panel geometry of the ship lends itself well to high volume production systems, minimizing tooling costs. And advances In numerically controlled milling machine technology also create extremely high levels of assembled part accuracy.

Accommodation is provided for a complement of twenty nine (officers and crew) on three internal decks (including bridge and combat control centre), with facilities and equipment also provided for deployment of special forces troops, including an 11 m high speed 50 knot RIB, also manufactured and supplied by North Sea Boats.

Trimarans offer very stable weapons platforms, and can carry various Missile systems; including Type 705 (up to 8), RBS15, Penguin or Exocet, and 40-57mm Naval Guns, or a CIWS (Close In Weapon System). These can be mounted high on the superstructure, giving better range and firing arc. Sensors can also be installed high up without concerns for stability. This first ship will carry a turn-key system delivered by CSOC and CPMIEC China, including rapid fire CIWS, combat control and missile systems. The exact configuration of this system is still classified.

Completion will take place after launching, and extensive sea trials and tests will commence in October. KRI KLEWANG is expected to be fully operational 2013.
