EVALUATION FACTORS

BID EVALUATION FACTORS.

The following criteria are for bidding purposes:

a. The dredge will remove an estimated 1,200,000 cubic yards (917,500 cubic meters) of sediments from the Ohio River channel and associated tributaries. The sediments consist of primarily medium to coarse-grained sands with a d50 of 0.03 inch (0.8 mm).

Laboratory analysis of the sediment samples taken from the project area indicate an average sediment dry unit weight of 126 lb/ft3 (2.019 g/cc). This measurement indicates 34.50 percent voids, based on the assumption of a 165 lb/ft3 (2.65 g/cc) particle density for sand. In the saturated state, such as sediments on the bottom of the project area, the void space is filled with fresh water, resulting in a saturated sediment density of approximately 141 lb/ft3 (2.257 g/cc).

The dredge efficiencies for this project are given in Table I and depend on the dredge configuration.

TABLE I – DREDGE EFFICIENCIES

Dredge with walking spud De = 0.50 Dredge with spud carriage De = 0.75

Bank height efficiencies are listed in Table II for various dredge sizes.

TABLE II-BANK HEIGHT EFFICIENCIES

20-inch (508-millimeter) Dredge Be = 0.80 22-inch (559-millimeter) Dredge Be = 0.75 24-inch (610-millimeter) Dredge Be = 0.71

The production calculation is to be based on the capability of the dredge plant to pump a 78 lb/ft3 (1.25 g/cc) slurry at the point in the dredging cycle in which the cutterhead is engaging sufficient bank height for loading the pipeline with slurry. The dredge production will be calculated in volumetric production (cubic yards), with the calculations based on the saturated sediment density. The carrier water has an assumed water density of 62.4 lb/ft3 (1.0g/cc). The pump head reduction coefficient (K) is assumed to be 0.24. The dredge production is calculated by the following equation:

PRODUCTION (CUBIC YARD/HR) = C * Q * 133.33 * De * Be with C, or [CUBIC METER/HR = C * Q * 3600 *De * Be] the percent by volume of in situ material in the flow, defined by the following equation:

with, pm - pw C = ------pI – pw pm = The specified slurry density of 78 lb/ft3 (1.25 g/cc) pw = The specified carrier water density of 62.4 lb/ft3 (1.0 g/cc) pI = The specified saturated sediment density of 141 lb/ft3 (2.257 g/cc) and, Q = The discharge flowrate ft3/s, (m3/s) See Appendix B for procedure to determine Q

133.33 = A conversion factor from ft3/s to yd3/hr 3600 = A conversion factor from second to hour De = The stated dredge efficiency of the dredge plant Be = The stated bank height efficiency for the dredge size

APPENDIX B

EVALUATION OF THE DREDGE PUMP

I. The evaluation of a dredge pump's ability to perform under a given set of conditions will be as follows:

GIVEN: d50 - Median particle diameter millimeters ρs - Particle density in lb/ft3, (g/cm3) ρi - Saturated density in lb/ft3, (g/cm3) ρm - Slurry density in lb/ft3, (g/cm3) ρw - Carrier water density in lb/ft3, (g/cm3)

DREDGE PUMP CHARACTERISTICS (Contractor Defined):

dd - Diameter of discharge pipes ft, (m) ds - Diameter of suction pipe ft, (m) ls - Length of suction pipe ft, (m) ld - Length of discharge pipe ft, (m) SPd - Maximum power rating of drive in HP, (J/s, W) RPMp - Maximum RPM of pump at SPd deye - Diameter of pump impeller eye ft, (m) dimp - Diameter of pump impeller ft, (m)

II. Procedure

a. Determine critical suction velocity (Vscrit) as indicated below ft/s or (m/s):

Vscrit = FL × (2 × g × ds × (SGs - SGw))½ where

0.125

-6.9×d50

FL = (1.3 × Cvd ) × (1 - e ) g = Gravitational constant (32.2 ft/s2), or (9.81 m/s2)

SGm - SGw

Cvd = ------------------- Assume Cvd = Cvi

SGs - SGw

SGs = Particle specific gravity (lb/ft3 or g/cm3) SGm = Slurry specific gravity (lb/ft3 or g/cm3) SGw = Carrier water specific gravity (lb/ft3 or g/cm3)

Appendix B - ii

b. Determine equivalent pipe length due to a fitting or bend using loss coefficients and the formula as indicated below:

D × k Le = -------------

4 × C

Le = Equivalent pipe length of a fitting or bend ft, (m) D = Diameter of the pipe ft, (m) k = Loss coefficient (See Table 6.12, Ref. 5) C = 0.004 for pipe dia. > 20 in (50.8 cm)

The total equivalent pipe length for the suction and discharge fittings or bends are given below:

n

Lse = Σ Lsen

I=1 n

Lde = Σ Lden

I=1

Lse = Total equivalent pipe length for suction bends, entrance, or fittings ft, (m) Lde = Total equivalent pipe length for discharge bends, exit, or fittings ft, (m)

The total equivalent pipe length for the system is given as:

Ls = Lse + ls and Ld = Lde + ld where Ls = Total equivalent pipe for the suction side of the pump ft, (m) Ld = Total equivalent pipe for the discharge side of the pump ft, (m)

c. Determine cavitation limits of the pump:

In the absence of Net Positive Suction Head (NPSH) data for the pump, the cavitation limit will be expressed as a function of the impeller eye speed and diameter. The impeller eye speed should be between 40 and 44 feet/second, (12.192 and 13.411 m/s). The cavitation speed (RPMmax) of the pump is calculated as follows:

Veye × 60

RPMmax = -----------deye × π

Veye = Impeller eye speed in ft/s, (m/s) π = PI 60 = Conversion from seconds to minutes

Appendix B - iii

d. The diesel driven engine is essentially a constant torque machine which results in the power output being directly proportional to engine speed. As a result, the maximum diesel driven power available in order to avoid cavitation (SPmaxavail) is calculated according to the following in horsepower:

RPMmax

SPmaxavail = ------------- × SPd

RPMp

e. The Total Dynamic Head (HTDH) requirements for the system will be determined as indicated in the following equations ft, (m) of slurry:

HTDH(units of slurry) = Hs(units of slurry) + Hd(units of slurry)

Hs(units of slurry) =Head requirements on suction side of pump Hd(units of slurry) =Head requirements on discharge side of pump and f×Ls×Vs

1.75 Vs

2 Dd×(SGm-SGw)

Hs(units of slurry) = ------------------- + --------- + -------------------ds×2×g 2×g SGm

Vd

2-Vs 2 f×Ld×Vd

1.75

Hd = ------ + Z + ----------------- 2×g dd×2×g ds

Vd = -----× Vs dd g = Gravitational constant 32.2 ft/s2, (9.81 m/s2) f = 0.028 friction factor for dredge slurries Vs = Suction velocity in ft/s, (m/s) (Vs > Vscrit) Dd = Dredging depth 33 ft, (10.058 m) Vd = Discharge velocity in ft/s, (m/s) Z = Terminal discharge elevation above reference datum 10 ft, (3.048m)

Appendix B - iv

f. The flowrate (Q) at V is calculated as follows in ft3/s, (m3/s):

π×ds

Qmin = ----- × Vscrit ds = diameter of suction pipe ft, (m) vscrit = critical suction velocity ft/s, (m/s)

Determine the minimum and incremental values of the flowrate (Q) and HTDH(units of slurry) by starting with the Vs equal to Vscrit and increasing the Vs in increments of hundreths of a ft/s by repeating paragraphs (e) and (f).

g. Determine the pump head reduction factor (RH) due to the solids effect in the pump as

Cvd dimp

RHo = K × -------, RH = RHo × (-------)-0.9

0.20 do

K = Pump head reduction coefficient, 0.24 RHo = Pump reduction factor for reference pump do = 1.15 ft, (0.351 m)

h. Determine the Pump Efficiency reduction factor (Re) due to the solids effect in the pump as

Re = 0.7 * RH

i. Since the pump head reduction factor (RH) is defined as follows:

HTDH(units of slurry)

RH = 1 - ----------------------------

HTDH(units of water)

The following is implied and should be calculated for all values of HTDH(units of slurry) in order to account for solids effect in pump:

HTDH(units of slurry)

HTDH(units of water) = ---------------------

(1 – RH)

j. Create a plot of HTDH(units of water) versus corresponding flowrates overlapping pump

Appendix B - v characteristic curves. This is the system curve. Determine an operating point, HTDH(units of water) , and flowrate (Q), and corresponding pump efficiency (Ep) in decimal format to the nearest thousandth from the system curve .

k. The Brake (Shaft) Power Required (SPreq) at an operating point is calculated as follows in horsepower or watts:

Q×HTDH(units of water) ×SGm Q×HTDH(units of water) ×SGm SPreq hp = ------------------------------- SPreq W = ------------------------------ × g

550 × 3960 ×(Ep - Re) 3960 ×(Ep - Re)

Q = flow rate ft3/s, (m3/s) HTDH= total dynamic head of water ft, (m) SGm = slurry specific gravity lb/ft3, (g/cm3) Ep = pump efficiency Re = pump efficiency reduction factor G = acceleration due to gravity 32.2 ft/s2, (9.81 m/s2)

l. In accordance with the governing affinity laws, the power demand of a centrifugal pump varies as the cube of the RPM. Therefore, the required pump speed (RPMreq) at an operating point for a centrifugal pump can be calculated as follows:

Procedure: Find a reference RPM and P, brake power in horsepower, from pump manufacturer's characteristic curves along a line of constant pump efficiency (Ep). Calculate RPMreq as indicated in the following equation:

SPreq

RPMreq = RPM × (--------- )1/3

P

m. As explained in part II-d, the diesel driven brake (Shaft) power available (SPavail) at RPMreq is calculated as follows in horsepower:

RPMreq

SPavail = ---------- × SPd

RPMp

n. The system operating point will correspond to the maximum flowrate that satisfies the following inequalities:

RPMreq < RPMmax SPreq < SPmaxavail SPreq < SPavail

Appendix B - vi

HTDH(Q) < HTDH(Qmax) HTDH(Q) > HTDH(Qmin)

o. Calculate Production based upon the operating point that satisfies all of the system parameters and utilizes the maximum flowrate.
