constituted a major milestone in DeJong
& Lebet, Inc.’s entrance into the high-performance workboat field.
totally new design is a significant milestone in establishing DeJong
& Lebet, Inc. as a major player in the design of high-performance
workboats. The design parameters for
this unique vessel included shallow draft and specific speed requirements, all
of which were met. To accomplish
this, the vessel was designed with three soft mounted MTU/DDC 16V 4000
propulsion engines each rated at 2,380 HP @ 2100 RPM, each driving a
model 811 water jet. The drive
train between the engines and jets consisted of remote, hard mounted, ZF model
BW755 reverse/reduction gear coupled to the engines through a flexible Centa
coupling. Cardan shaft assemblies
manufactured by Driveline, Inc. completed the link between the gears and
waterjets. The combined components
resulted in a high speed, vibration free vessel.
than 300-gross ton vessel is of all aluminum construction and has an ABS
unlimited loadline. The unusual
vessel is fitted with a Hydra-Pro model 40/18K hydraulic pedestal crane with a
capacity of 18 L. tons, at 10’ and 4 LT @ 40’.
The helo deck, designed to handle a 6,000 lb. helicopter also provides
shelter for two 20’x8’ scientific modules.
Special deck reinforcements allow movement of these modules around the
aft deck and over the stern to shore.
is equipped with two tender vessels. The
larger vessel is a 28’ aluminum Packman jet drive landing craft, built by
Munson Manufacturing. The second
tender is a smaller RIB type vessel.

crew/scientist accommodations below Main Deck consist of six four-person cabins
and one VIP stateroom. A laundry
room and two heads complete the below deck accommodation spaces.
The Main Deckhouse includes a full Galley, large Mess Area, Captain’s
Cabin with private head, a Wet Locker, Survey Room, Walk-in Cooler/Freezer,
Common Head, and large Dry Stores/Pantry area.
The Pilothouse, located above the Main Deckhouse, features 360º
visibility. The electronics package
was state-of-the-art designed for unlimited oceans service and extensive weight,
trim, and speed/power calculations resulted in a vessel that met displacement
and speed requirements dead-on. At
the vessel’s lightship displacement of 191 LT, plus minimum liquids and crew,
the design speed of approximately 32-knots was achieved.
Fully loaded, the vessel is expected to displace 370 tons and run at
The vessel has successfully operated for more than eight months and has
met or exceeded all design requirements in every aspect, a tribute to the
combined efforts of the Owner, the Designers, and the Builder.

involved in the engineering for this modification.
