This 120’ x 40’ aluminum SWATH crew boat was built
in 1999 for Trico Marine to quickly shuttle as many
as 250 passengers to offshore platforms. She was
built by Eastern Shipbuilding Group and designed
by Petrobras. The goal was to create an offshore
crew transport vessel that would phase out costly
helicopter rides and rough voyages on convention,
mono-hull crew boats. The SWATH design provided
a smooth ride and met the requirements of an
average speed of 25 knots. This vessel is
capable of speeds over 30 knots.

The ergonomic requirements were defined to limit
the incidence of seasickness to less than 5% in 4 hours
exposure in the 2- to 3- meter seas so common to the
Campos Basin where the vessel would operate. They
also required comfortable seating, ample legroom
and an HVAC system with a relatively high rate of
exchange. The final design presented a number of
challenges, while incorporating many high tech features,
such as a gas turbine coupled to controlled pitch
propellers via a 27:1 reduction gear and an active fin system.
