Seakeeping Test of Yacht |
Oceanic conducts seakeeping evaluations
on a wide range of marine systems, from supply vessels and motor
yachts to warships and large oil production and storage structures.
Knowing the performance of a vessel in a seaway can be significant
for the design of hull structure and for the placement of crucial
on-board equipment. In addition, with the increasing concern for
passenger comfort, knowledge of wave-induced motions and accelerations
is becoming increasing important for designers of passenger-carrying
vessels.
During physical model testing, Oceanic can record measurements
for a wide range of parameters, limited only by the size of the
model. On the structural side, measurements of global (hull-girder)
loads and local (e.g. slamming) loads can be recorded in real-time
along with propulsion system response (thrust, torque) and rudder
angles. Measurements of rigid-body and localized accelerations
are also commonly recorded. In multi-directional seas in
Offshore Engineering Basin, model position and attitude
are recorded via a non-contact optical tracking system to eliminate
interference. For all tests in waves, high-quality video recording
is offered, and video results can be time-scaled to reflect the
performance of the full-scale vessel.
While direct measurements on scale models is perhaps the more
common approach to seakeeping studies, the physical capabilities
at Oceanic are enhanced by numerical
analysis using a proprietary 3-D time domain simulation
code. The optimum method of evaluating a particular design is
generally some combination of these elements, adjusted to meet
the requirement of the client. By benchmarking numerical results
with model data in critical areas allows a designer to explore
vessel and sea conditions that would be prohibitively expensive
or even impossible with a physical model.
