Chinese operator CNOOC Ltd has asked contractors to submit fresh prices in a subsea facilities tender for its deep-water Lingshui 17-2 gas field development in the South China Sea's Qiongdongnan basin.

Sources said CNOOC Ltd initially set a workscope that included subsea trees for 11 production wells plus five spare units and four manifolds, a subsea distribution unit, connections, an umbilical termination head, umbilical termination assembly, subsea umbilical termination units as well as umbilicals.

There were suggestions that there had been some changes in the workscope but sources said these did not concern anything significant.
