LONGITUDINAL STRENGTH OF SHIP HULL 



LANGUAGE 

 COMPUTER 



FORTRAN IV 

 IBM 7090 



EXTENDS THE STATIC BALANCE METHOD OF CALCULATING SHEAR AND BENDING 

 MOMENT RESPONSES TO INCLUDE A WIDE RANGE OF WAVE HEIGHTS, LENGTHS, 

 AND POSITIONS WITH RESPECT TO AMIDSHIPS FOR A SHIP VERTICALLY BALANCED 

 IN HEAD-ON TROCHOIDAL WAVES. THE PROGRAM HAS THE OPTION OF INCLUDING 

 OR OMITTING THE SMITH CORRECTION, AND THE FINAL DATA MAY BE PRESENTED 

 IN EITHER TABULAR OR GRAPHICAL FORM. PROGRAM YP04 PROVIDES A MEASURE 

 OF THE LONGITUDINAL STRENGTH FROM THE STATIC BALANCE. YP05 IS A METH- 

 OD OF PLOTTING THE LONGITUDINAL STRENGTH CURVES, PROGRAMMED BY MRS.

 COMPUTER 



FORTRAN IV 

 IBM OS/360 



DETERMINES WAVE STATISTICS OF A SEA RECORD. THE STATISTICS INCLUDE — 

 NUMBER OF WAVES, R.M.S., MEAN, MAX., AND SIGNIFICANT WAVE HEIGHT, AND 

 SPECTRAL DECOMPOSITION OF THE SEA SURFACE. OUTPUT — PRINTOUT OF WAVE 

 STATISTICS, AND PLOT OF SPECTRAL ESTIMATE. AUTHOR — J. E. MAMRING.

REFRACTION OF WAVES APPROACHING A COASTLINE 



LANGUAGE 

 COMPUTER 



FORTRAN IV 

 IBM 7090/94 



A PROGRAM TO CONSTRUCT REFRACTION DIAGRAMS AND COMPUTE WAVE HEIGHTS 

 FOR WAVES MOVING INTO SHOALING WATER. CONSISTS OF MAIN PROGrAm WAVES 

 I AND SUBROUTINES RAYCON, REFRAC, CURVE, DEPTH, HEIGHT* ERROR, WRITER. 

 SOLVES THE REFRACTION EQUATION AND THE WAVE INTENSITY EQUATION FOR AR- 

 BITRARY BOTTOM SHAPES. SOLUTION WAS SOUGHT BY USE OF THE NUMERICAL 

 METHODS OF FINITE DIFFERENCES. ONE OF THREE HYDRAULIC ENGINEERING 

 PROBLEMS DESCRIBED IN TECH. REPT. NO. TR-80 ( JUN 67, 185 P) BY R. S.
