Abstract

A METHOD FOR INSTALLING RISERS SO THEY EXTEND FROM A FPU (FLOATING PRODUCTION UNIT) TO MULTIPLE SUBSEA HYDROCARBON WELLS OF AN OIL FIELD, WHICH AVOIDS DAMAGE TO THE PIPE SECTIONS AND THAT IS ECONOMICAL. AS PIPE SECTIONS ARE CONNECTED TO A NEAR END (56) OF A PIPE STRING PORTION (688-680) THAT LIES AT THE FPU, A TUG BOAT (30) PULLS THE FAR END (65) OF THE PIPE STRING TOWARD A WELL HEAD. INITIALLY, A LONG PULL LINE (34) EXTENDS FROM A WINCH (32) ON THE TUG BOAT, IN A DOUBLE CATENARY CURVE TO THE FAR END OF THE PIPE STRING. THE WINCH IS OPERATED TO SHORTEN THE PULL LINE UNTIL THE PIPE STRING EXTENDS IN A DOUBLE CATENARY CURVE (60). TENSION IN THE PIPE STRING IS MAINTAINED AT A PROPER LEVEL DURING INSTALLATION BY MAINTAINING THE NEAR END PORTION OF THE PIPE STRING SO IT EXTENDS AT A NEAR END ANGLE (70) TO THE VERTICAL THAT CONTINUALLY LIES WITHIN A PREDETERMINED RANGE, SUCH AS FROM 3° TO 12°.
