Feature Vessel Garibaldi Glass on L.A. Fireboat 2 Using a frameless window, direct-glaze tech- nique, Garibaldi Glass Industries supplied a tempered glass laminate combination to provide both strength and safety on the LAFD's newest vessel — L.A. Fireboat #2. The windows were coated with a baked on perimeter black ceramic frit during manu- facturing and were then bonded into place using a Sika polyurethane adhesive. The bonded window application will reduce long term maintenance and eliminate all potential for leaks, an important concern considering the 38,000 gallons per minute of water that can be launched into the air around them. Garibaldi's frameless glass has also been installed aboard vessels built for Navy, Coast Guard, and Fire/Rescue service. Circle 171 on Reader Service Card Wynn Installs Wipers Wynn Marine completed the installation of a window wiping system for a new Los Angeles Fireboat. The wiper system is based on the Type C Internal motor Straight line wiper from Wynn's heavy duty Ocean Range. Wynn wipers use materials such as 316 stainless steel. Good wipers are are particularly important for operation on the LA Fireboat, which can pump as much as 38,000gpm of water into the air, a condition that can seriously affect visibility on bridge windows. In conjunction with the wiper sys- tem Wynn has also installed its top of the range Series 3000 control system which comes with either a flat keypad or highly flexible touch screen LCD. The control sys- tem can handle up to 50 wipers on one cir- cuit. Circle 169 on Reader Service Card Ship Trio is Largest to Sail St. Lawrence River The largest ships ever to be deployed in the St. Lawrence River are on target to start services later this year with the keel laying in South Korea of Canada Maritime's 4,100 teu containership Canmar Spirit. The first ship in the newbuilding program, Canmar Venture, is on schedule for delivery in July with the Canmar Spirit following in September. The ships, which are being built by Daewoo Shipbuilding & Heavy Machinery, will each be 965 x 106 ft. (294 x 32.2 m), with a draft of 35 ft. (10.7 m). Their nominal capacity is 4,100 teu, with a service speed of 22 knots. These are two of three ships ordered to operate in Canada Maritime's Northern Service. OOCL, Canada Maritime's long-standing partner in the St. Lawrence Coordinated Service (SLCS) has ordered the third vessel. SLCS offers three weekly routes through the Montreal Gateway. Route 1 links Montreal with Thamesport, Antwerp and Le Havre; Route 2 links Montreal with Antwerp and Hamburg and Route 3 links Montreal with Liverpool. The Big One: L.A. Fireboat 2 The Los Angeles Fire Department (LAFD) has accepted its new fireboat, L.A. Fireboat 2, which is the largest in the U.S. according to its length of 105 ft. (32 m) and a fire-fighting capacity of more than 10,300 cu. m. /hr. Built to replace the 75-year-old Ralph J. Scott, it was designed by Robert Allan Ltd. And constructed in 18 months by Nichols Brothers Boat Builders. The basic principle of this ship was developed by Voith Schiffstechnik, Germany and it is based on the Voith Water Tractor. During fire fighting the pumps are running with 70 percent of the main engine power and the remaining 30% are sufficient for the vessel to main- tain an exact position. The vessel has a unique hull form developed by Robert Allan Ltd. in order to create very low wake wash profile at medium speed patrol operations within the Port of Los Angeles. According to Doug Moore, chief engineer at the LAFD's Fire Station #112, where the vessel will be home-ported, "The new fireboat was able to match the LAFD's needs for a design that incorporates the abilities of an escort tug with the latest in firefighting technologies." Moore, who also served as the fireboat's project man- ager, added that he was equally impressed with the vessel's efficient fuel savings, which can be attributed to its unique hull form and Detroit Diesel engines. "The cruising fuel economy of this vessel is twice than what we expect- ed," he said. A radio-controlled model was constructed and tested in order to verify that the wake profile was accept- able, and also to verify speed and maneu- verability characteristics. The forward hull is typical of a VSP propelled vessel, however the aft end has a quite different form, more reminiscent of the style of high-performance ASD tugs for which the designers are noted. Propulsion and steering control are provided by twin Voith cycloidal pro- pellers, Model 26 Gil/165, provided by Voith Schiffstechnik, each driven by an MTU/Detroit Diesel Model 12V4000 diesel engine, rated 1,800 bhp (1,343 kW) at 1,800 rpm, which also drive a fire pump through a front end PTO. In addi- tion, a pair of MTU/Detroit Diesel 8V- 4000 pump engines each drives two fire pumps. All machinery is resiliently mounted for minimization of noise and vibration transmission. The fire-fighting system delivers a total of 36,000 U.S. gpm at the system operat- ing pressures of approximately 10 bar (136,080 1pm or 8,165 cu. m. /hr.) deliv- ered from a total of six pumps to all the monitors. The entire fire-fighting pump and monitor system was provided by UnitorAB (formerly Svenska Skum AB). The main piping is a major design fea- ture, prominently mounted in a ring around the upper boundary of the deck- house, with the monitors mounted direct- ly above. The wheelhouse is designed to provide maximum possible all around visibility, with excellent overhead visi- bility through large visor windows. To keep a clear view, it is outfitted with a Wynn wiping system. The largest fireboats show their power. (Photo credit: The Port of Los Angeles) Main Particulars - L.A. Fireboat 2 Length, o.a 105 ft.
