Responses Of Tension Leg Platform (Tlp) Due To Wave Spectrum

Tension leg platform (TLP) is among the compliant platforms that vertical
moored with excess buoyancy. The design of TLP is as the same design of other
moored structures in horizontal plane. First order wave force is presented as the
dynamics response of TLP and considered the degrees-of-freedom surge, sway,
heave, roll, pitch and yaw. Included in this report are the history and the
fundamental design of the tension leg platform. Besides that, the basic concepts
of the buoyancy force and wave spectrum are also included in this TLP. The
calculation of horizontal force and vertical using the Morison equation and RAO
(Response Amplitude Operator) are included in chapter 3. The scale model
dimension and drawing of Ram Powell is provided in this report. The effects of
different parameters that influence the response of the TLP are then investigated.
There are graphs in the result consisting of the P-M and JONSWAP spectrum
graph, wave elevation graph, time series of horizontal forces graph, RAO
(Response Amplitude Operator) versus frequency graph, surge, heave, pitch
spectrum graph and surge, heave and pitch response graph. All this graphs are the
result from calculation using the Ram Powell Tension Leg Platform criteria and
specification. Based on the analysis of the real platform, it gives idea on the
response of tension leg platform model prototype due to the wave spectrum.
Attached in this report is the work schedule for the task needed for the way
forward. Included in this report is the model testing of fabrication model at
Offshore Laboratories. From the model testing, graph of fabrication model
responses due to wave is plotted
