The pipe laying program required 120 lineal metres of trench to be dredged and backfilled per day. The volume of material involved to meet the program required both the Nu Bounty and Nu Endeavour to be engaged on site. The trenching and pipe laying was undertaken with both Nu Endeavour and Nu Bounty, the pipe lay barge and both spreader barges working\u201c in train\u201d together working across Botany Bay. The pipeline trench was 6,970metres long, starting from Kyeemagh on the northern side of Botany Bay finishing at Kurnell on the south west side of Botany Bay. The design of the pipeline trench required 710,000 m3 of material to be dredged and back filled during this phase of the project.\u00a0 This part of the project required significant interfacing
