Cementing 30" cond (subsea) without an inner string

Hi folks

We would like to know people´s experience of cementing 30” conductor
on a floater without using an internal stinger (particularly anyone
who has done this with a 20” or 13 3/8” swaged shoe)?

Prior to a DWOP, our drilling contractor experts have recommended to
do this based on the fact that this is how the rig has always
cemented conductors whilst operating for a previous client. Our
main concern if we go this way is ensuring that we displace the
cement to a point below our 30” x 13 3/8” swage and sufficiently
above the shoe to avoid a wet shoe and yet not leave too much cement
to drill out.

Comments and ideas are most welcomed.

Many thanks
James Gillan
