Abstract:
1. A method of connecting a tension leg platform (TLP) to a tender-assisted drilling (TAD) vessel comprising: a) attaching a first connector to a first end of a first support line; b) attaching an opposing, second end of the first support line to the TAD vessel at a first, higher location proximate the midline of the TAD vessel; c) attaching a first end of a second support line to the first connector; d) attaching an opposing, second end of the second support line to the TAD vessel at a first, lower location proximate the midline of the TAD vessel; e) attaching a first end of a first hawser to the first connector; f) attaching a second, opposing end of the first hawser to the TAD vessel at a first hawser connection location; g) attaching a first end of a second hawser to the first connector; h) attaching an opposing, second end of the second hawser to the TLP at a second hawser TLP connection location; i) attaching a second connector to a first end of a third support line; j) attaching an opposing, second end of the third support line to the TAD vessel at a second, higher location proximate the midline of the TAD vessel; k) attaching a first end of a fourth support line to the second connector; l) attaching an opposing, second end of the fourth support line to the TAD vessel at a second, lower location proximate the midline of the TAD vessel; m) attaching a first end of a third hawser to the second connector; n) attaching a second, opposing end of the third hawser to the TAD vessel at a third hawser connection location; o) attaching a first end of a fourth hawser to the second connector; p) attaching an opposing, second end of the fourth hawser to the TLP at a fourth hawser TLP connection location.
