anchorage, may be suspended in the harness for a length-of-
time if self-rescue or rescue by co-workers cannot be performed
Sustained immobility in a body harness may lead to
suspension trauma also known as harness induced pathology
as described in reference (a). Suspension trauma resulting
from the accumulation of blood in the veins commonly
called venous pooling. The symptoms (known as orthostatic
intolerance) of suspension trauma include lightheadedness,
dizziness, weakness and occasionally fainting.
Normally when an individual faints and collapses, the
pooled blood is now no longer being held down by gravity
and returns to the heart, where it is once again distributed to
the body. Assuming no injuries are caused during the collapse,
the individual will quickly regain consciousness and recovery is
likely to be rapid.
When an individual hangs in a harness in a vertical or near-
vertical position without moving his legs, the same thing can
happen; only this time when he passes out he remains vertical.
An accumulation of blood in the legs reduces the amount
of blood in circulation. After an initial speeding up of the
heartbeat, the heart rate then slows down and blood pressure
will diminish in the arteries. The reduction in quantity and/or
quality (oxygen content) of blood flowing to the brain leads to
unconsciousness and harmful effects on other vital organs. If
these conditions continue, they potentially may be fatal.
As one can see…the importance of a timely rescue of a worker
suspended in a harness or who has become incapacitated
due to an injury and/or heart attack mandates the need for a
written rescue plan. n

DIVER PRODUCTIVITY AT VARIOUS DEPTHS
In addition to diving operations, the cost of dry-condition
construction also increases with depth. Greater depths produce
larger hydrostatic pressures on the underlying system. To resist
these pressures, the amount of material and bracing required to
construct cofferdams and dikes will also increase.
ILLUSTRATION OF A TRADITIONAL COFFERDAM
The structural design and detailing of the traditional cofferdam
is typically conducted by the contractor’s engineer. Special
consideration must be taken to ensure the structural integrity of
the cofferdam. In addition to resisting hydrostatic pressure, the
engineer must take into account the effects of the river current,
channel bottom configuration, seepage pressures, water level
variation, and site restrictions. Cofferdam design and construction
may be further complicated by remains of previous cofferdams and
seals left in place and pier batter piles. The contractor determines
the maximum water elevation for design, weighing risk factors
such as seasonal river changes and work duration. Constructability

issues must also be examined by both the contractor and engineer
to ensure that the cofferdam can be erected and dewatered during
the course of work. Overhead clearance may limit installation of
sheet pile cofferdams around existing bridges. The use of vibratory
pile hammers reduces overhead clearance requirements, but room
must be sufficient to handle and position the sheets. Sheets can be
set in short sections with welded splices, but this is very expensive.
Additional concerns arise since the cofferdams are subject to, and
may aggravate, local pier scour.
Cofferdams will experience leakage and provisions must be
made for continued pumping. This may require personnel to be on
site even when construction activity is not underway.
Dikes can be constructed around work areas to provide a dry work
condition. A variety of materials can be used to construct the dikes,
including roadside barriers and plastic sheeting, sand bags, and
compacted clay. An advantage of using dikes includes construction
with the use of limited heavy equipment and inexpensive materials.
However, dikes are restricted to use in shallow water areas with
limited flow. In addition, compacted clay and other materials
used in dike construction may have to be disposed of as a
contaminated material after use.
PROPRIETARY BARRIER SYSTEMS
Several types of proprietary barrier systems are available for
use on marine projects. Some commonly available systems consist
of water filled bladders and membrane covered support frames.
These systems are typically limited to waters less than 10 feet

NOW THIS IS
Y es, we found this Picture immediately to your left as
“Unique” a Crawler as we had seen in a while. As
you can see from the Photo’s below left, you have
your Conventional Crawler Crane with Cab Body
Cab mounted directly above the tracks, as well as a Photo
of what a typical Crawler Mounted Excavator with the Cab
Body mounted directly above the tracks working in water,
placing Rip-rap. As you can see, such an Excavator has its
limitations; more specifically…deep water.
Obviously, ANY conventional Crawler Crane and/or Crawler
mounted Excavator has its limitations when working in the water.
One is basically limited to boom reach and then of course, the
water level and well, once it reaches the top of the tracks…that’s
the end of that! You go any further and the next thing you know
your Cab Body is under water, and we don’t need to explain to you
what happens next to your Diesel Engine.
Then we recently came across the following Photo…
Now this, we found UNIQUE! I must say, in my 30+ years of
being in the Marine Construction Industry I have NEVER come
across a “Crawler” with an Extended Cab Body as shown in the
picture above; hence the reason for wanting to share this Photo
with our readers. While I don’t know the exact height of the
“extension” itself, based on the individuals walking in the picture,
my best estimate would be 6 ft. at a minimum. I would not be
surprised if this set-up was able to install the ENTIRE sheet pile
breakwater in the background the ENTIRE length into the ocean;
thus, eliminating the need for a Crane Mounted Barge to complete
the work in deeper water.
I will say this, while my immediate thoughts were “what an
incredible idea”! But, if it is such a novel approach to the design
of a Crawler, then why hasn’t Link-Belt, American, Manitowoc,
Liebherr, P & H, Kobelco, Mantis or even CAT for that matter
producing such an animal?
Well, I could only imagine that an “extension” of this kind might
just play “hell” with the Mfgrs., suggested “Lift Capacity Ratings”.
Let alone, there goes any “Low Center of Gravity” with the Cab Body
Six (6) ft., higher than normal. Who only knows what the maximum
reach would be? I am by no means an expert on Crawlers; far from
it. However, we at MC Magazine would be interested in hearing
from any of our readers as to your comments. Feel free to send
them to the Attention of Chris Smoot - Editor, Marine Construction

NDATION ERICAN PILE
RESERVE, LOUISIANA - On October 16, 2018, after 38
remarkable years in the dredging industry, David Miller, SVP/COO
and part owner of DSC Dredge, LLC announced his retirement. Miller
embarked on his career in the early 1980’s when he began working
for Kenner Marine & Machinery (KMM). Following several consecutive
KMM positions, David completed his final 10 years there as a field
David Miller was one of the original founders of Best Equipment
Technologies, Inc. (BEST), established in 1998, located in Poplarville,
MS. BEST operated as a steel fabrication shop and dredge
manufacturer. Partnered with the Wetta family, Miller helped found
companies that provided essential services to the dredging industry.
In 2010, these companies were consolidated into DSC Dredge, LLC
(DSC) and the group forged ahead, enhancing its reputation as a
world leader in the manufacturing of portable cutter suction dredges.
With his career in the dredge manufacturing industry affording the
opportunity, Miller remains an avid traveler today. Bob Wetta, DSC
President and CEO explained, “David can boast that he has visited
all 50 USA states, as well as over 50 countries. We are proud to
recognize David for his unconditional dedication, commitment and
hard work.” Wetta continued, “David Miller will be deeply missed,
yet we can only feel happy for him after his many years of expert
service.” Fellow owner Bill Wetta, Senior Vice President of Product
Development and Chief Technology Officer added, “DSC Dredge is
simply a better company because of David’s valuable contributions
and incredible impact made during his career and within our
company. On behalf of everyone at DSC, we wish David the very
best. May this next chapter of life continue to allow new adventure
and continued travels!”n

The FIRST Amphibious “Long Reach” Excavator that CAN Actually Excavate while in a Floating State!
A “self-propelled” amphibious excavator/marsh buggy
specifically designed to maneuver in marshy, swampy, soft
terrain areas it can also float on water as an added safety
feature. With its self-propelled feature, it can access virtually
all terrains yet requires minimum supporting transportation
and hoisting equipment. More impressive, with its optional
Hydraulic “Spud System”, one can literally excavate while the
Tracks are in a Floating State!
HYDRAULIC EXTENDABLE PONTOONS
An optional design feature allows each pontoon to retract or extend
outward hydraulically. A fully retracted pontoon with reduced footprint
provides the added advantage and convenience of transporting the
machine by trailer without dismantling into modules.
SUPPLEMENTARY PONTOONS AND SPUDS
Supplementary pontoons can be easily attached onto the outer side of the primary pontoons to enhance
stability. The hydraulic-mechanical spuds system which is control from the operator cabin is a superb solution
to overcome buoyancy in deep water, providing additional stability and enhanced operability on water up
to 12’ deep. Users can choose to add the supplementary
pontoons and spuds system at the later stage when need arises.

PILE DRIVING the USCG requirements for “Lifting”.
RIGS The load rating of a floating crane/derrick shall be the
maximum working loads at various radii as determined by the
manufacturer or qualified person considering list and trim for
each installation. The load rating shall specifically reflect the:
design standard; machine trim; machine list; and dynamic/
environmental loadings anticipated for the operational
envelope of the floating crane/derrick or auxiliary shipboard
The load rating is dependent upon the structural competence
of the crane or derrick, rope strength, hoist capacity, structural
attachment to the floating platform, and stability and freeboard
of the floating platform.
When deck loads are to be carried while lifting, the situation
shall be analyzed for modified ratings.
When mounted on barges or pontoons, the rated loads
and radii of land cranes and derricks shall be modified as
recommended by the manufacturer or qualified person. The
modification should always be evaluated by the qualified
person specific to the floating platform mounting the crane.
Load charts should be generated based on the crane load rating
for floating service. In addition, the load charts for floating
service must comply with the specific standard it was designed
for and clearly explain the floating platform and dynamic/
environmental parameters that apply to the load chart.
The load chart should, at a minimum, identify the following:
¡¡ Draft limits (with deck cargo considered),
¡¡ Vessel motion limits,
¡¡ Vessel and crane list/trim limits, and

and property hazards result from the fumes, gases, sparks,
THE hot metal and radiant energy produced during hot work. Hot
work equipment, which may produce high voltages or utilize
BASICS compressed gases, also requires special awareness and
training on the part of the worker to be used safely. Arc welders
32 | ISSUE #1 - 2019 marineconstructionmagazine.com are trained to take appropriate precautions to prevent the skin
and eye burns that can occur as a result of exposure to the UV
emitted during arc welding. However, it is also important to
ensure that persons in the vicinity of the welding operations are
prevented from entering areas where arc welding is occurring
and are warned not to stare at the arc. The hazards associated
with hot work can be reduced through the implementation of
effective control programs.
PREPARING HOT WORK AREAS
Areas where hot work is done should be properly designated
and prepared. Combustible and flammable materials within
the work area should be protected against fire hazards and the
operation should not pose a hazard to others in nearby areas.
To help achieve this, the following controls should be used:
¡¡ Cutting and welding operations are performed only by
authorized, properly trained individuals;
¡¡ If possible, hot work must be performed in a properly
designed shop area equipped with all necessary controls
and adequate ventilation;
¡¡ Move combustible materials at least 35 feet from the work
site. If this is not possible, protect combustible materials with
metal guards or by flameproof curtains or covers (other than
¡¡ Cover floor and wall openings within 35 feet of the work site

to higher construction costs, underwater construction is also more
hazardous to the worker.
42 | ISSUE #1 - 2019 marineconstructionmagazine.com
Providing the contractor with schedule flexibility, within reasonable
project limits, may help mitigate some risk factors.
Insurance requirements become more complicated and expensive
when the work involves underwater construction. Separate policies
and riders are often required to provide additional coverage for
underwater work that is not specifically covered with a primary
policy. The following will address the different types of insurance
involved with underwater contractors and what owners need to
consider. Certificates of insurance should be provided to the bridge
owner for all policies in place.
Worker’s compensation is a no fault type of insurance that
provides compensation and medical assistance for workers who are
injured during the course of employment. It also pays death benefits
to dependents for job-related injuries. All employers in the United
States are required to carry worker’s compensation insurance.
Diving contractors pay higher premiums than most contractors.
Rates are based on amount of hours spent in the water by the
contractor’s divers. The insurance company underwriting the policy
audits payroll records each year to determine rates. Rates for
contractors providing diving services are usually 30-40 percent
higher than typical above water service rates. Subsequently most
diving contractors have wet pay and dry pay rates depending on
the type of work.
LONGSHOREMAN’S INSURANCE is communicated in detail on the design drawings and in the
United States Longshoreman’s & Harbor Work Act (USL&H) specifications. A significant amount of effort may be required
