The Sapura T-9 is a purpose built barge-type self-erecting tender assisted drilling (TAD) rig with a flat bottom, raked stern and bow hull shape. The rig is designed as a cost efficient solution for development drilling involving multiple well slots on fixed wellhead platforms. The mooring system is designed to enable it to work on TLPs and SPARs in up to 6,000 feet of water depth with pre-laid mooring.
