Alternative to rig crane for deploying VSP air-gun

Dear members

At a recent virtual-DWOP in Aspac region, the team were discussing how to avoid tying up the rig crane for deploying VSP guns.  The reason is that the well-test spread is being rigged up and the use of a crane would delay the rig-up.

Without going into why the Welltest spread is being rigged up so close to being needed, we'd like to hear what effective solutions our members have used to deploy VSP air-guns.  This is a jackup in ca. 100 m water-depth.

One solution being looked at is using a “moon-pool” tugger.

So, what solutions have you applied and what (if any) lessons learnt?

Many thanks

Dave
