M/V CONDOR EXPRESS WAKE WASH MEASUREMENT TRIALS

February 2, 2002

EXECUTIVE SUMMARY

Worldwide ferry traffic has simultaneously increased in both volume and in vessel speed,

the resulting negative effects of wake wash on shorelines has become an increasing

environmental concern. Consequently, wherever expanded ferry service is contemplated,

there is a need to measure the contribution that a specific ferry will make to the wake

wash environment.

All American Marine requested that Fox Associates measure the wake wash of a new

vessel design, anticipated for use as a ferry in one or more routes. The vessel, M.V.

CONDOR EXPRESS, differs from most catamarans in that its fitted with foils that

provide dynamic lift. This feature, dynamic lift, is known to reduce water resistance and

therefore reduce the amount of energy that is used to make waves.

The tests were conducted in Bellingham Bay on 22 February 2002, in water depths that

are similar to those found in several west coast waterways such as Rich Passage in Puget

Sound and the high-speed vessel lanes in San Francisco Bay. Wind conditions were

minimal and the investigators were able, using proven computer techniques, to filter out

the effect of the wind driven waves from the vessel waves. The vessel was loaded to

approximate the weight and weight distribution of an average passenger load for a vessel

with a capacity for 149 passengers1. The investigators used a procedure that theyve used

in measuring wake wash on more than 40 vessels in the last ten years, assuring thereby

that the results would be comparable with those of other vessels.

1 149 passengers is a threshold established by the U.S. Coast Guard for certain features, and CONDOR

EXPRESS was compared with other vessels in this category.


3/65

The results of these measurements showed that M.V. CONDOR EXPRESS, at the

loading of the test day, has exceptionally low wash characteristics, both in height and in

energy. Specifically:

At full speed, 39 knots, CONDOR EXPRESS has a lower wash energy2

(776joules/meter of wave front) than any vessel with a capacity of 149 passengers or

more tested to date by the investigators, at any service speed.

At full speed, 39 knots, the wash height is less than 20 cm. and 28% below the

threshold established by Washington State Ferries for Rich Passage2

At speeds below 12 knots and above 23 knots, CONDOR EXPRESS meets the

standard for operation in Rich Passage.

2 There is not a universal standard for wake wash height or energy. Washington State Ferries has

established a threshold of acceptability for Rich Passage of 2450 joules/meter of wave front and a height of

28 cm.

M/V CONDOR EXPRESS WAKE WASH MEASUREMENT

TRIALS, 2/22/2002

BACKGROUND ESTABLISHMENT OF WAKE WASH STANDARDS

The advent of fast ferries in restricted waters has generated concern, real or perceived, about the

wake wash of these vessels and the impact on sensitive shorelines, structures and other vessels.

For example, in 1991, after introduction of two monohull ferries into service from Seattle to

Bremerton, WSF was forced to slow these ferries to a speed of 12 knots through Rich Passage, a

narrow (800 yards) protected passage between the Kitsap Peninsula and Bainbridge Island, lined

on both sides by the beaches of private residences. Many of these residences have constructed

bulkheads and retaining walls on the beach to protect their property from wind and vessel driven

waves. A comprehensive study by shorelines experts concluded that, given all other sources of

wave energy impacting these beaches and bulkheads, the WSF monohull ferries at 12 knots had a

negiligible effect in the long term. WSF then measured this acceptable level of wash from thesevessels in deep water (eliminating shallow water and critical depth effects) to establish a WSF

Rich Passage wash standard, measured 300 meters from centerline of vessel travel. This

standard is a wake wash height of less than 28 cm peak-to-trough wash height and wake wash

energy of less than 2450 joules per meter energy density in the tallest wave in the wave train.

The standard described in the example above is appropriate for Rich Passage only. It would be

erroneous, incorrect and environmentally undefendable to apply this criteria to other locations.

The number of variables involved, such as passage widths, shoreline slope and configuration,,

waterway topography, marine life, and aquatic beds, weather patterns, wind fetch and vessel

traffic almost certainly will define a different environment for a different location and therefore

call for a different criteria..

PURPOSE

To measure the wash signature of the M/V CONDOR EXPRESS for All American Marine and

to determine its characteristics in approximately 60 feet of water depth, simulating the shallowest

depth in Rich Passage mid-channel.

DEFINITION OF TERMS USED IN ANALYSIS

Wake Wash Height: the height, measured in centimeters, from peak to trough, of the highest

wave in the series of waves produced by the passing of the measured vessel. Wake wash heightis measured or mathematically normalized to a distance of 300 meters perpendicular to the

centerline of travel of the vessel. 300 meters is chosen to provide a basis for comparison

between various vessels measured under similar circumstances by the investigators.

WakeWash Period: the time, in seconds, for one complete wave cycle to pass a fixed point.

The period of the highest wave in the series of waves produced by the passing of the measured


7/65


22

vessel is determined by the time difference between the zero crossing of the start of the highest

wave and the zero crossing of the start of the next wave in the series.

Wash Energy : Wash energy is calculated from the standard formula in numerous texts (the

U.S. Army Corp of Engineers Shore Protection Manual for one) of:

E g H L=

2

8

where is the density of water, g is the acceleration due to gravity, H is the wash height, and L is

the wash wavelength. The term for wavelength in this formula is to be replaced by a function of

wash period from the relationship given below:

LgT

=

2

2

resulting in the following equation:

Eg H T

=

2 2 2

16

In metric units, with H in meters and T in seconds, this formula reduces to:

E H T = 1961 2 2

with the output expressed in joules per meter of wavefront.

METHODS

Wave heights and periods of vessel wash are measured using a submerged instrument package

that measures pressure 4 times per second and records data to a HEX file in computer memory in

the package. The instrument package is anchored to the bottom, typically in 200 feet of water,

and suspended from a buoy that is held 6 to 10 feet below the surface of the water by a taut line

to the anchor. A marker buoy on the surface is used for location and recovery. This test setup is

depicted in the following illustration:

PROCEDURE

The site chosen for these trials was in Bellingham Bay, southeast of Portage Island as shown in

the chart below.

The site was chosen for its protection from the NW wind and where the vessel would be passing

over a changing water depth with a depth of about 60 feet at the point where the vessel passed the

measuring buoy. During the trials, wind was primarily from the northwest at speeds from 10

knots, diminishing to 5.

To gather data, the test vessel passed the deployed instrumentsat a convenient distance at various specified speeds. The actual

distance is measured using a laser rangefinder. Wash measurement

runs were conducted at nominal speeds of 10, 16, 22, 28, 34 and

40 knots with the vessel in the nearly fully loaded condition

(46.4 tonnes). All data that was consistent and repeatable was

analyzed. Each runs data was normalized to a distance off

centerline of travel of 300 meters (~1000 feet) and, where


10/65


55

possible, the multiple run data for each speed was averaged.

Data from the last run (a semicircle at maximum speed to develop a combination wave) was

plotted at the actual distances taken. Plots were then developed of wash height

vs. speed, wash period vs. speed and wash energy vs. speed.

RESULTS

Based on the plots presented in Section 3, Summary Graphs, CONDOR

EXPRESS, in approximately 60 feet of water, at a distance off

centerline of travel of 300 meters:

At a speed of 39.0 knots, produces an average maximum wash

height of 20 cm at a displacement of 46.4 tonnes.

Produces a wash energy density of 776 joules per meter at a

displacement of 46.4 tonnes at a speed of 39.0 knots. This

wash energy density is measured for the tallest wave in the

wave train. Hump speed for CONDOR EXPRESS is 16.5 knots

The following graphs present the wake wash performance of CONDOR

EXPRESS. Plotted values less than zero should be ignored as a

charting software anomaly. Dynamic trim, which was measured on

board by an electronic device which averaged trim over a 30

second period, is presented first so that the reader can note the

point (at 29 knots) where the aft trim foils broach the surface

and limit the lift at the stern.

COMPARISON TO OTHER VESSELS

The following graphs compare the wash height and energy density

of CONDOR EXPRESS to other vessels that have been measured by the

authors. For this comparison, vessels which commonly transit

Rich Passage in Puget Sound were used as well as the M/V ST.

NICHOLAS, a comparable 149 passenger vessel for which the wake

wash data has been publicly released.

During the conduct of the test, two pleasure boats (~50 ft. power cruisers) passed the

instrumented buoy at about 15 knots and their wash was recorded for analysis and comparison.

Their wash was also normalized to a standoff distance of 300 meters. The wash characteristics of

these vessels is noted on the comparison charts.

ANALYSIS AND DISCUSSION OF RESULTS

Trim and Wash Period

At speeds above 29 knots, the mid foil of CONDOR EXPRESS lifts the stem clear of the water

and the broaching of the after foils keeps the waterjet inlets submerged. This action of the foils

has two effects on the wake wash of the vessel:

Lifting the stem clear of the water reduces the waterline length of the vessel which

reduces the period of the bow wave. Bow wave periods of about 4 seconds could be

expected for a vessel of this size. Reduction of the bow wave period to about 3

seconds results in wash of significantly lower energy than would be expected otherwise.

With the stem just clear of the water, traveling through wind waves or slight porpoisingcauses variations in the effective waterline length. The result is that the tallest wave or

the most energetic wave is not always the same wave in the wave train and there are more

than the usual variations in the period of the tallest wave. Normally, in our analysis, we

can overlay most of the six runs at any one speed to obtain an average tallest wave on

which to base the summary curves. In the case of CONDOR EXPRESS, overlays were

not possible and the averages were obtained after individually plotting each run.

Combination Waves

For the last run on the trials, the vessel circled the observation boat for 180 degrees to create a

combination wave on the inside of the turn. We observed two distinct wave patterns with

characteristics as follows:

PATTERN HEIGHT (CM) ENERGY (J/M)

1 43 22892 59.1 4001

These combination waves can clearly signiificantly exceed the straiught line waves, and these

measurements illustrate the importance of carefully planning the point in a transit where course

changes are made.

Comparison with M/V ST. NICHOLAS

The wash height of CONDOR EXPRESS at 39 knots is more than that of ST. NICHOLAS at

27.7 knots but CONDOR EXPRESSs wash energy is significantly less. The lower energy is due

to the shorter period bow wave of the CONDOR EXPRESS. This table gives the values:

CONCLUSIONS

CONDOR EXPRESS exhibits the typical magnitude of wash pattern for an aluminum catamaran

of its length and displacement. The maximum wash height and energy density occurs at a speed

of 16.5 knots followed by a decreasing wash height and energy, up to 29 knots. Though there

are variations in these characteristics above 29 knots, the curves are essentially flat from 29 to 39

knots.

At speeds below 12 knots and above 23 knots, CONDOR EXPRESS, at 46.4 tonnes, meets the

wash acceptability criteria established for Rich Passage in Puget Sound by Washington State

Ferries. Compared to other ferry vessels transiting Rich Passage, all admitedly larger, CONDOR

EXPRESSs wash at maximum speed of 39 knots is superior and is sufficiently below the

acceptability standard for Rich Passage that the risk of exceeding the standard due tomaneuvering is very low. Route planning for any ferry transiting Rich Passage must pay careful

attention to the direction of travel of combination waves from the point where course changes are

made.

CONDOR EXPRESS has the lowest wash energy at service speed measured to date by the

consultants on any passenger vessel with a capacity of 149 passengers or more. Other vessels in

this size range have a lower wash height, however.
