SEACOR CHEETAH: Fastest workboat on the water
hai guyss, sebelum ni aku ade share pasal apa itu FCB. So kalini aku share pasal FCB yang terpantas di lautan
The cheetah is the fastest animal on land, capable of top speeds of 70 mph in short bursts. Speed is no doubt why Seacor Marine LLC, of Houma, La., named the newest addition to its fleet of offshore vessels Seacor Cheetah. It’s the first in what the company calls its CrewZer series.
While unable to travel quite 70 mph, the new 170-foot crew/supply boat did reach speeds of 42 knots during sea trials in the Gulf of Mexico, making it by far the fastest workboat ever built and challenging the dominant role played by helicopters as a fast, safe way to transfer workers out to rigs and platforms.

With a 38-foot beam, it is also the widest crew/supply boat ever built. Due to its catamaran design, the hull is 14.67 feet deep.
The key to the speed of any vehicle, whether on land or at sea, is to look under the hood, or in this case inside the two slim hulls on which this vessel is built.
Each contains a pair of MTU 16V 4000 engines developing 3,305 hp and working into a Twin Disc Nico gear that reduces engine revolutions at a ratio of 2.17:1. The engines power Hamilton HM811 waterjets. In each hull there is also a 290 kW genset powered by a Cummins QSM11 engine and a 360°, 200 hp azimuthing bow thruster by Thrustmaster.

The ability to transport a relatively large number of passengers at 40-plus knots changes the equation of using crew boats or helicopters for crew transport. With Cheetah, owners can carry more than twice the number of crew (149 versus 60 to 70 for a typical crew boat) at a speed differential of about 15 knots over existing boats.
At 42 knots, Seacor Cheetah consumes 644 gallons of diesel per hour at 2,000 rpm. In cruising mode, at 38 knots, fuel consumption is 474 gph at 1,800 rpm. Even at economy speed, running at 1,500 rpm, the vessel scoots along at 31 knots using 265 gph — and Seacor Cheetah’s economy speed is several knots faster than the top speed of the vast majority of crew/supply boats.
Seacor Cheetah can carry up to 150 tonnes of cargo on its 91 by 30-foot rear deck. The rear deck is also approved for carrying combustibles in approved tanks.
Special equipment includes a pair of remote-controlled fire monitors with a capacity of 5,300 gallons per minute. While rig fires are not common, Seacor felt these would be helpful since, with its speed, Seacor Cheetah may be first on the scene of a fire.
Seacor Cheetah carries 25,900 gallons of fuel oil, about 50 percent of which is transferable. To document offloads, a 2-inch fuel meter with a ticket printer monitors the flow and delivers a receipt. Discharge rate is 120 gpm at 288 feet. Other liquids on board include 3,600 gallons of potable water, sewage, bilge oil, gear oil and main engine lube oil. Deadweight tonnage is estimated at 182 long tons.
Safety systems abound on Seacor Cheetah. For firefighting on board there is a fixed CO2 system in all machinery spaces. A closed-circuit television system covers the rear main deck, engine room and thruster room. There are 10 deck lights totaling 6,500 watts plus two forward searchlights and one 12-inch searchlight aft with a remote control. Smoke and heat sensors are located throughout the ship.
The pilothouse contains two Furuno depth recorders and engine control and steering by Hamilton, the waterjet manufacturer.
Navigation equipment in addition to the DP-2 system includes two Furuno 2127 radars and a ComNav 2001 autopilot. Communications gear includes two Icom M504 radios, a Furuno FS1503 SSB, International marine Sound Powered internal telephone, a Raytheon 430 loud hailer, VSAT Internet e-mail, and a Furuno NX700 Navtex.
