LIGHTING SYSTEM
The RRDF lighting system consists of four trailer-mounted light towers which are stowed in two 20 ft ISO
containers. Each light tower is powered by a 6 KW diesel generator and supports four metal-halide lamps. Each lamp
delivers 1000 watts of light intensity. Lamps are a high pressure sodium bulb with a NEMA 6 design for large area
coverage. The aluminum reflector housings have tempered impact resistant glass lenses. The lamps come with
weather resistant twist-lock connections for connecting floodlights to the light tower.
The light tower is a three-section telescoping mast which extends from 12 ft to 30 ft and has a rotation range of 360o
with a position lock. The mast is easily extended with dual hand-operated winches that incorporate an automatic
safety brake. The tower retracts and stows horizontally for travel.
The light system comes with a 30 gallon translucent polyethylene fuel tank, single point lifting bail, forklift slots,
heavy-duty outriggers, leveling indicator and removable drawbar. The control panel comes with one Ground Fault
Interrupter (GFI) protected, 120 volt, 20 amp duplex receptacle; one 240 volt, 25 amp receptacle; individual lamp
switches and a non-resettable hour meter to track records for periodic maintenance.
The overall length is (in./cm) 174/442, width is (in./cm) 79/201, height is (in./cm) 89/226 (travel position), standard
tower height is (ft/m) 30/9 and shipping weight is (lbs/kg) 2010/912.
LIFELINE SUBSYSTEM
The lifeline subsystem is installed along the sides of the RRDF platform to protect personnel from falls overboard.
The stanchions for the lifelines are installed in the turn-tube fittings and ISO corner fittings of the section modules.
The lifelines are installed on the inboard side of the lifeline stanchion. Chain is used to span the gap between
the sections.
COMMUNICATIONS EQUIPMENT
The communications equipment consists of eight VHF/FM handheld transceivers. The transceivers have a frequency
range of 156.025 to 163.275 mHz. All channels currently allocated in the USA, Canadian and International channels
are available for use, plus ten weather channels.
The VHF/FM handheld transceiver has an RF power output with the CNB350 battery of 5.0 watts (high) and
1.0 watts (low). The operating voltage is 7.2 volts DC. The current drain in standby mode is 40 mA, in receive mode
200 mA, in the transmit mode 1.8 amps (high power) and 0.7 amps (low power). The battery life (5% Tx, 5% Rcv,
90% standby) is approximately 10 hrs (high) and 15 hrs (low).
The dimensions of the unit are 5.51 in. H X 2.17 in. W X 1.50 in. D. The weight is 1.0 lb.
The transmitter has a conducted spurious emissions of 65 dB (high) and 55 dB (low).The audio response is within
+2/-8 of 6 dB/octave pre-emphasis characteristic from 300 Hz to 3000 Hz. The AF harmonic distortion of the
transmitter is 3%. The transmitter has a hum and noise rating of 37 dB and a frequency stability (-20° to +50°C)
of +/- 0.0005%.
The receiver has a sensitivity rating of 20 dB quieting at 0.35 uv and 12 dB SINAD at 0.30 uv. The squelch
sensitivity (threshold) is 0.20 uv. Modulation acceptance bandwidth is +/- 4.5 kHz receiver selectivity: spurious and
image, rejection 60 dB, intermodulation regulation 60 dB and channel spacing 25 kHz.
RIGID HULL INFLATABLE BOAT
The rigid hull inflatable boat, which is stored in a 20 ft ISO container, provides transportation for the crew of the
RRDF. It has a seven person capacity and is fitted with a 70 horsepower gasoline outboard motor. The boat is
approximately 15 ft 5 in. (4.70 m) long and has a beam of 6 ft 7 in. (2.01 m). The inflatable tube has a diameter of
20 in. Lifting weight is approximately 1000 lbs. The max loading capacity for the boat is 1903 lbs.
