Narcotrafic : Interception d'un go-fast en Méditerranée

29/11/2010

La préfecture maritime de la Méditerranée a annoncé,

samedi, l'interpellation de trafiquants de drogue en

Méditerranée. Leur embarcation, un navire rapide de type

go-fast, a été interceptée mercredi dernier par une action

coordonnée de la Marine nationale et de la douane. Quatre

hommes se trouvaient à bord et 30 kilos de drogue ont été

saisis. Les autorités françaises estiment qu'avant d'être

interpellés, les trafiquants ont jeté à la mer 1.8 tonne de

produits stupéfiants. L'enquête a été confiée à la juridiction

interrégionale spécialisée de Marseille, les quatre hommes

étant remis au service de la police judiciaire de Marseille.

Depuis 2006, 19 embarcations ont été interceptées et 15

tonnes de drogue saisies, 25 autres tonnes ayant, estiment

les autorités françaises, été jetées à la mer. Ces opérations

s'inscrivent dans le cadre de la lutte contre les trafics

illicites, conduites depuis 2006 par le préfet maritime de la

Méditerranée, elles se poursuivent en coordination avec la

douane, le centre de coordination de lutte anti-drogue de la

Méditerranée (CECLAD-M), le SRPJ de Marseille ainsi que

les procureurs de Toulon et de Marseille, siège de la

juridiction interrégionale spécialisée (JIRS).

Suite à la découverte de problèmes de structures sur les patrouilleurs du type Cyclone basés à Norfolk et Bahreïn, la marine américaine a décidé d'immobiliser les 5 unités déployées dans le golfe Persique (Typhoon, Sirocco, Chinook, Firebolt, Whirlwind). Les bâtiments ne reprendront pas leur activité avant deux mois. D'ici là, des travaux de réparations seront menés, indique l'US Navy. Un chantier similaire sera réalisé sur les Tempest, Hurricane, Monsoon, Squall et Thunderbolt, basés à Norfolk. Ces unités pourront naviguer mais, en attendant la fin des réparations, sont soumises à des restrictions (vitesse, état de la mer...) Une inspection est, enfin, actuellement en cours sur les trois patrouilleurs prêtés par la marine aux garde-côtes (Zephyr, Shamal et Tornado). Construits dans la première moitié des années 90 par les chantiers Bollinger, les bâtiments de la classe Cyclone mesurent 51.8 mètres pour un déplacement de 330 tonnes en charge. Capables de filer 35 noeuds, ils sont armés par 30 marins et disposent d'un canon de 25mm et quatre mitrailleuses de 12.7mm.

Incendio de la BAP Clavero en el Putumayo durante su primer despliegue operativo – Una crónica de los hechos

Tras zarpar el dia 18 de Mayo de la estación naval homónima instalada en Iquitos, la cañonera BAP Clavero (CF-15) inició su primer despliegue operativo en la Cuarta Acción Cívica Binacional Conjunta con la Armada Nacional de Colombia, a iniciarse el 01 de junio en la localidad peruana de Gueppi, donde reunirá al Buque Hospital BAP Morona (ABH-302) y a la cañonera ARC Leticia (CF-136).
La cañonera BAP Clavero (CF-15) en el día de su comisionamiento a la flotilla amazonica de la Armada Peruana.
La acción cívica, de 60 días de duración, tenía previsto recorrer 96 poblados rivereños: 55 peruanos y 41 colombianos, efectuando atenciones médicas, odontológicas, obstétricas, laboratorio, así como la entrega de DNIs, registros e inscripciones a cargo de la RENIEC, entrega de Pabellones Nacionales, víveres, útiles escolares, ropa, material deportivo y corte de pelo, destacando la entrega de 4,000 paquetes familiares de víveres a cargo del PRONAA y de 617 laptops escolares, proporcionadas por el Gobierno Regional de Loreto.
Emergencia en el Putumayo: Se ordena abandonar el buque
El día lunes 24 de mayo, a las 1530 horas, mientras navegaba en el río Putumayo en demanda del poblado de Gueppi, sufrió un incendio de gran magnitud a bordo y pese a que se activaron los procedimientos de Lucha Contra Incendio éste no pudo ser controlado, ocasionando averías de consideración, lo cual motivo que el personal de abordo evacue la nave.
Medios locales indican que el incendio se originó durante el mantenimiento de uno de los motores diesel del navío, en el cual resultaron afectados con severas quemaduras de segundo grado el Técnico de Tercera Motorista Desio Lachi Reátegui y el Oficial de Mar Tercero Maquinista Luis Gonzáles Pezo, los cuales fueron evacuados a la posta médica del poblado de ERE, para finalmente ser trasladados a Lima.
Tras el siniestro, los restantes miembros de la dotación fueron concentrados en el poblado de Belén, para ser trasladados a la ciudad de Iquitos. Cabe indicar que se contó con la participación de unidades de la Marina de Guerra del Perú y de la Armada Nacional de Colombia durante las operaciones de apoyo al control del siniestro.
Finalmente, la citada unidad arribó a la localidad de San Antonio del Estrecho, con la finalidad de continuar con las reparaciones necesarias para permitir que la unidad continúe con sus operaciones programadas. Asimismo la dotación de la unidad viene desplegando sus actividades propias de la situación producida a bordo de la unidad.
Objetivos del Operativo Binacional no fueron afectados por el siniestro

Con relación a la Acción Cívica Binacional con Colombia programada para iniciarse el 1ro. de junio, ésta se ejecutó de acuerdo a los objetivos y poblados programados con el Buque Hospital BAP Morona, habiéndose diferido únicamente, en coordinación con los pares colombianos, a esta unidad fué trasladada la totalidad del personal y del material que se encontraba embarcado en el BAP Clavero.

Buque Hospital BAP Morona (ABH-302) completó con la misión asignada para la Acción Cívica Binacional sin mayor novedad tras el siniestro
Con respecto a los valerosos marinos heridos que sufrieron quemaduras, actualmente vienen siendo atendidos en las instalaciones del Centro Medico Naval del Callao por médicos especialistas. Cabe mencionar que la Marina de Guerra del Perú, desde el inicio del incidente viene coordinando con los familiares de los tripulantes que sufrieron este accidente a bordo del BAP Clavero para hacer llegar la ayuda necesaria e información oportuna sobre su condición clínica.

Por otro lado, se ha dispuesto el inicio de las acciones administrativas correspondientes a fin de determinar las causas de este accidente, para lo cual desde el día martes 25 de Mayo ya se encuentran a bordo de la siniestrada cañonera los ingenieros del astillero SIMA Iquitos, especialistas en este tipo de incidentes con la finalidad de evaluar los daños y determinar las causas del siniestro.

La BAP Clavero (CF-15), perteneciente a la Comandancia de la Flotilla Fluvial y adscrita a la Comandancia General de Operaciones de la Amazonia, es una cañonera fluvial diseñada y construida por el astillero SIMA Iquitos, tiene una eslora total de 45,5 metros, manga de 10,6 metros y calado mínimo de operación de tan solo 0,61 metros; característica indispensable para que el buque sea capaz de alcanzar las guarniciones mas alejadas de la cuenca amazónica donde la escasa profundidad de los ríos impide la presencia de las restantes cañoneras nacionales. Su desplazamiento es de 340 toneladas.
Pese a sus reducidas dimensiones y desplazamiento, la BAP Clavero se encuentra fuertemente armada, tal y como se aprecia en esta fotografía tomada el día de su entrada en servicio.
La propulsión corre por cuenta de tres motores diesel Caterpillar 3408C turbo alimentados que generan un total de 1.365 CV y permiten una velocidad máxima de 14 nudos y una mínima, operando con un calado de 0,61 metros, de unos 8 nudos. Su tripulación está conformada por 51 efectivos: 3 oficiales, 28 especialistas y 20 efectivos del Batallón de Infantería de Selva Nº 1.
El armamento se compone de cinco ametralladoras Browning M-2 HB de 12,7 mm. y dos lanzagranadas CIS-40 de 40 mm. en montajes automatizados de fabricación nacional y al menos seis misiles MANPADS 9K38 Igla, para defensa aérea cercana. Cuenta ademas con 2 lanchas rápidas de asalto para el despliegue de las tropas embarcadas en la mencionada unidad fluvial.
El buque entró en servicio el 9 de Abril de este año tras haber superado exitosamente varios meses de pruebas de navegación y demás sistemas de abordo sin novedad alguna. Actualmente se halla en construcción una segunda unidad de la misma clase, llamada BAP Putumayo (CF-16) en el astillero del SIMA Iquitos.

vessel was discovered some 20 feet below street level

In New York City, an even greater surprise awaited excavators at the World Trade Center site: On July 13, an 18th century sailing vessel was discovered some 20 feet below street level, the possible result of property owners using it as landfill to extend the edge of Manhattan Island during the 1700s. Given the accelerated rate of deterioration of the wooden structure now that it’s exposed to the air, archeologists worked with Corinthian Data Capture to scan the vessel using infrared lasers. The resulting data digitally depicts every detail and feature of the hull, enabling further study and future creation of a 3D model of the vessel.
Reuters provides the best images I’ve seen so far of the vessel and the site.
Even the Titanic is back in the news, with a team of scientists scheduled to launch an expedition to the wreck site on August 18 to determine the current state of deterioration of the legendary ship. State-of-the-art imaging technology will be used to map both the wreck itself and the large debris field, as one of the goals of the expedition is to “virtually” raise the doomed vessel for the public to see.
In the October issue of (mt), we’ll be delving into the use of laser scanning in the upgrading of existing vessels. Gerald Moore, of Daphne, Alabama-based Ship Architects, Inc., will share with us the work his organization is doing with Todd Pacific Shipbuilding Corp. to upgrade two Coast Guard ice breakers, the Polar Sea and the Polar Star. Using laser scanning tools to capture dimensional data on the vessels, Ship Architects, Inc. creates 3D, “as built” models of the ships, which can then be used to model sister ships less labor-intensively and more accurately.
It’s part of the October issue’s special focus on technology transfer and will include everything from 3D immersive virtual reality design tools to the ways in which the U.S. Navy’s Manufacturing Technology program is developing and transitioning enabling technologies to industries that support production and sustainment of Navy weapons systems.
We’ve grown accustomed to technology that enables faster, cheaper, and more accurate vessel design. But tools like 3D laser scanning give us the opportunity to capture and bring forward the past—and the present—and leverage that data, that learning, to visualize and build ships that otherwise might remain on the drawing board.

AIRCRAFT CARRIERS FROM THE FUTURE

Four of the world's 10 largest navies are preparing for new classes of aircraft carriers.
The UK is getting ready to take a huge leap forward with the HMS Queen Elizabeth, the People's Republic of China is moving ahead with the Varyag, India is taking onboard the $2.34bn Admiral Gorshkov carrier and the US is changing its tactics with the Gerald Ford-class.
Royalty for the UK
When it comes to new carriers, the UK is arguably preparing to take the largest step forward. When it enters service, probably sometime in 2015, the HMS Queen Elizabeth will be the largest ship in the Royal Navy's long, long history.
"The British learned a lot in the Falklands war of 1982 where they saw the limitations of small aircraft carriers," Eric Wertheim, author and editor of the US Naval Institute's Guide to Combat Fleets of the World,says.
At 65,000 tons and just a bit smaller than an American Nimitz-class carrier, the Queen Elizabeth-class carriers (there will be two in total) are 284m long and can carry up to 50 aircraft. Replacing the Invincible class, the BAE-designed ships will use cheaper, integrated full-electric propulsion with Rolls-Royce Marine Trent MT30MW gas turbines.
"When it enters service, probably sometime in 2015, the HMS Queen Elizabeth will be the largest ship in the Royal Navy's long history."While few specifics regarding technology are yet known, the ship is expected to far outclass the Invincible, and offer the Royal Navy a strategic push forward in naval warfare.

FUTURE AIRCRAFT CARRIERS China chooses Soviet power

China is also moving ahead with a carrier and may be nearing entry into the world's flat-top club. After years of speculation about what exactly is happening with the incomplete former Soviet carrier the Varyag, the Chinese navy may be only a year or so away from beginning sea trials. The Varyag was an Admiral Kuznetsov-class carrier, but construction was halted in 1992 with the break-up of the Soviet Union. The ship eventually became property of the Ukraine, which later sold it to China, supposedly with the stipulation it would never be made operational as a carrier.
An August 2009 US Department of Defense report on the state of the Chinese navy stated the carrier is expected to become operational between 2010-2012, and will likely be used to develop basic proficiencies in carrier operations. "Speculation is that the new Chinese carrier will carry an air wing of either [Sukhoi] SU-33 or a derivative of [Shenyang] J-11 aircraft," it said. Jane's reported in 2008 that the Chinese carrier will be called the Shi Lang.
Although there's been no official announcement of any kind from the Chinese government, Wertheim said a domestically produced Chinese carrier is likely "sometime after 2015". The Japanese news network Nippon reported in January that development work on one or two 50-60,000-ton new Chinese carriers is underway at a military facility in the city of Wuhan, with future construction planned at a Shanghai shipyard

FUTURE AIRCRAFT CARRIERS India and Russia

India is preparing to accept a Russian carrier.
In a visit to the country in mid March, Russian Prime Minister Vladimir Putin signed three defence contracts with his Indian counterpart, Manmohan Singh. In the largest agreement, India agreed to pay Russia $2.34bn for the 45,000-ton Admiral Gorshkov carrier.
"India is far too reliant on Russia and this is costing it domestic shipbuilding expertise."The Admiral Gorshkov was first commissioned by the Soviet Union in 1987, but since a 1994 boiler room explosion it has been unused, with the exception of a period between late 1995 and early 1996 when it briefly returned to service with the Russian fleet. In 2004, the Indians agreed to purchase the ship for $974 million, but the Russians later negotiated the sales price upwards in return for making modifications to the long-dormant carrier. It is expected to be delivered in mid-2012. Once accepted by the Indian Navy, the ship will be known as the INS Vikramaditya.
"The Indians have some very impressive plans for the future, but are seeing very slow progress on their carrier programmes," says Wertheim. "I think they are far too reliant on Russia and this is costing them domestic shipbuilding expertise in the long run."
The two other agreements signed by Putin and Singh were a $1.2bn deal for India to purchase 29 more Mig-29K aircraft from Russia and a $600.7m cooperative venture on a new transport aircraft.
In a December 2009 news conference, India's top admiral, Nirmal Verma, told reporters that the Indian Navy will launch a 40,000-ton domestically built carrier sometime in 2010. However, while the keel of that ship was laid down in March 2009, the Indian Navy has now called for a commissioning date of 2014, although many analysts are sceptical that even this revised deadline can be met.
India’s lone existing carrier, INS Viraat, will mark its 50th year of active service later this year.

FUTURE AIRCRAFT CARRIERS The US's 'evolutionary' Gerald Ford class

The US is taking an "evolutionary step" with the new Gerald Ford class. Similar in size to the Nimitz class, the 100,000-ton Ford is due to enter the US fleet in 2015 and will be able to accommodate the new F-35 multi-role fighter. With two higher-power nuclear reactors and a design created to reduce the ship's radar profile, the Ford will give its commanders new flexibility and capability, says Wertheim.
"Improvements such as better catapults allowing for greater launch potential, increased sortie rates, smaller crew size and decreased maintenance requirements will give a more capable platform that is also easier to maintain and keep on station then previous carrier designs," Wertheim says.
The US Navy currently maintains a fleet of 11 carriers – 10 Nimitz class and one Enterprise class. Wertheim says he expects the fleet to be relatively stable in size for the next decade or so.
"I see the number of large-deck US Navy carriers remaining relatively stable during the next 10 years, but decreasing slightly, perhaps by 20%, during the next 20 years," he says. "The carriers are getting more expensive to build and there is simply not enough aircraft to fill their flight decks anymore."

Composite Materials Development and Processing

•The United States Office of Naval Research is currently funding a project designed to develop polymer composite materials to be used in naval vessel construction. The program is also focused on creating manufacturing methodologies for these materials that will be time- and cost-effective. Exactly what these materials will be is unclear, as a polymer is any material made of countless molecules of different elements. Polymers behave according to their composite molecules. The primary goal of the project is to develop fire-resistant materials with low smoke emission.

Cleaner and safer operation

An innovative triple screw hybrid mechanical/electrical propulsion system combines a central controllable pitch propeller (CPP) with two Azipull thrusters with nozzles for the best in propulsive efficiency. The system allows the UT790 CD to use the minimum fuel to do the job in its various operating modes, with maximum flexibility.
Modes range from sailing in diesel-electric mode at 10 knots and sailing in mechanical mode using only one engine at 14 knots, to combined systems for maximum pull and an efficient system with a high level of redundancy for dynamic positioning. Click to view main modes.
Rolls-Royce Bergen engines meet Clean Design class rules without further exhaust cleanup. Catalytic converters can be fitted to the generator sets, giving ninety per cent NOx reduction.
With its special redundant drive solution, the forward azimuth thruster can be powered by two independent switchboards, enabling the UT 790 to achieve the same DP2 capability with three thrusters than conventional solutions with four.
The UT 790 CD comes with a full Rolls-Royce Safer Deck Operations (SDO) system, including anchor-handling cranes, chain wheel changer and torpedo anchor-handling system. SDO introduced four years ago is seen as standard equipment on high-end anchor handlers. It improves safety by keeping the crew away from danger zones, while maintaining operational flexibility and efficiency.

UT 790 CD Deepwater anchor-handler

Stability with efficiency
Normally a larger beam for greater stability would imply extra hull resistance, but the UT 790 benefits from a new 23m form that has lower resistance than traditional 20 and 22m designs and combines a wave piercing bow that pierces through the water rather than riding on top of the waves.
This allows the vessel to run continuously at service speeds regardless of sea-state and eliminates slamming. At speeds of 14 knots and violent storm conditions (waves higher than 9m), tank tests show no water above forecastle deck level. In extreme wave heights, water will be visible at the forecastle long before the situation gets critical, allowing power to be reduced and the maintaining of generous safety margins.
The UT 790 CD re-thinks anchor handler layout, moving the engines further aft and locating the secondary winches low down, where the engine room would traditionally be, to help improve stability and free-up space.
The UT 790 CD has the same fibre and rope capacity operating with four secondary winches as a traditional anchor-handler has with six. The vessel has the power and capacity to handle cable, chain and rope down to 2000 metres, and fibre rope down to 3000 metres.
Another notable feature is the extra buoyancy in the cargo railings, providing further stability and safety in case of extreme heeling levels.
Locating the engine room astern also reduces engine noise and permits shorter exhaust ducting which includes a Mecmar wet exhaust system, with cooled exhaust leaving the ship at sea level.
As there are no exhaust casings the enhanced 360-degree view from the bridge significantly improves safety.
