Damen Delivers the Patrol Boat Valiant Damen Shipyards Gorinchem deliv- ered the Damen Stan Patrol 4207 Valiant to H.M. Customs and Excise. Following the earlier delivered Seeker, Searcher and Vigilant, Valiant is the fourth Damen Stan Patrol 4207 for H.M. Customs and Excise. The Damen Stan Patrol 4207 is one of the bigger types in the Damen standard range of patrol boats, starting from 12 m in length and reaching up to 52 m. The steel hull and aluminium super- structure were subcontracted to Scheepswerf Made in The Netherlands and the outfitting was carried out at Damen Shipyards Gorinchem. The twin screw propulsion system consists of the following components: Caterpillar main engines; Reintjes gear- boxes; and Kamewa CPP propellers. Although the ship will sail at patrol speeds between 12 to 17 knots most of the time, the maximum speed is 26.5 knots. For slow speed maneuvering in harbors a bow tunnel thruster is fitted. During design and construction of the ship much attention has been given to minimise vibration and noise levels. For this purpose the engines are fitted on flexible mounts. Floating floors are used throughout the ship and walls are of the "box in box" principle. As a result, the noise levels are remarkably low for such a light and high-powered ship: Wheelhouse helmsman position 59 dBa Messroom 57 dBa Cabins 54-59 dBa Galley 65 dBa Circle 34 on Reader Service Card IZAR Christens LNG Ship Izar's Puerto Real Shipyard christened the LNG carrier Cadiz Knutsen, with representatives of the owners Knutsen OAS and Marpetrol and the final client, Union Fenosa Gas. This ship will trans- port up to 138,000 cu. m. of gas at - 163°C, and is the fourth LNG carrier built at IZAR, and the second one of those built at Puerto Real facilities. There is a third unit under construction at this shipyard for the shipowner Fernandez Tapias. The vessel will trans- port gas from the Damieetta port lique- faction plant in Egypt to the gasification terminals in Ferrol and Sagunto. Izar has three similar LNG carriers, two from the Sestao Shipyard and one more at the Puerto Real yard Cadiz Knutsen has a time charter con- tract signed in the year 2000 between Union Fenosa Gas and the owners Marpetrol from Spain. Knutsen will operate the LNG carrier by bareboat charter. The LNGs built by Izar conform to all existing regulations, including double hull, double bottom in the cargo area, and the four cryogenic cargo tanks with GTT Membrane Type No. 96 E2, where the natural gas is transported at atmos- pheric pressure and at a temperature of - 163° C. This membranes, directly attached to the ship's double hull/double deck, etc., have two missions: To reduce the transfer of heat to the atmosphere and the cargo tanks to minimize the evaporation of liquefied natural gas and thermally insulating the structural steel and transmitting the cargo's weight to the steel structure. Each of the 0.7 mm thick and 500 mm large membranes, made of Invar sheets (metal alloy with a 36% content of nickel), counts with an insulating barrier of two layers of perlite (aluminium oxide of granular shape with silicon)-filled plywood casings to prevent water and humidity. WITH SAMSON ROPES the cost of mooring just went down Today's high performance synthetic ropes are stronger than equivalent sized wire ropes, without the problems. They last several times longer in the same application, don't fish hook, and require no re-lubing. Lightweight synthetic lines are flexible and easy to handle - usually requiring fewer crewmen for most operations, and they won't damage deck equipment. That translates into reduced costs, and increased efficiency and safety. Call, write, or visit our website, you'll find real solutions to real problems using high performance synthetic ropes engineered and manufactured by the stongest name in rope 2090 Thornton Street, Ferndale, WA 98248 360.384.4669 www.samsonrope.com £ THE STRONGEST NAME IN ROPE Circle 213 on Reader Service Card June 2004 25
