Probabilistic Specification of Metocean Criteria:
Generating and Searching N-Year Contours for Extreme Response Estimation
The HTCNTR, IFORM, and SURFIT Routines (Report RMS-32)
The source code file contains, in zipped format, files associated with the release of the HTCNTR routine. This is part of a suite of programs (HTCNTR, IFORM, SURFIT) that constructs and searches N-year contours of (Hs, Tp) seastate characteristics at different locations.
HTCNTR is the simplest of these programs -- it merely constructs the N-year contour -- i.e., gives (Hs, Tp) pairs -- for various sites.
Method: Inverse FORM.
To Compile: Compile and link the routines src/htcntr.f and src/hstp.f, create executable file htcntr.x
Usage: htcntr.x > htcntr.ctr
User will be prompted for input (site location and desired return period N). Output will be stored in htcntr.ctr
Subdirectories:
src contains the FORTRAN source code (htcntr.f, hstp.f)
examples contains output files *.ctr from running different cases (e.g., gom.ctr, statfjord.ctr, etc.)
Documentation: RMS Report 32
Status: Htcntr has been recompiled on a Mac using the public domain compiler GNU FORTRAN (see src/htcntr.cmp and src/htcntr.x)
Results from the examples directory have been confirmed.
