Sonsub's I10 and I11 ROVs assisted a pipe lay set at 2,175 m, said to be a world record, during the Canyon Express project in the Gulf of Mexico. Both ROVs working off SaiBos's FDS conducted more than 200 dives logging more than 3,500 hours between the two, with I10's longest dive at 143 hours and I11's longest at 201 hours. The ROVs performed touchdown monitoring up to 650 m behind the vessel, bathymetry, and pipe tracking survey. They supported the mud mats and inline sleds settings. The company's I3 and I12 recently helped install a dozen hydraulic leads on the same field. The ROVs latched onto the 800-lb leads and flew them to their locations for installation from the MSV Maxita. Electrical leads installed included a hybrid of fiber-optic end connectors. TotalFinaElf operates the Canyon Express field. Sonsub agreed to supply tooling for the project and to assist with a single methanol distribution line and two 12-in. installed flowlines and electro-hydraulic umbilical installations in up to 7,200-ft water depth.The umbilical system controls four subsea wells at the King's Peak field, three to four subsea wells at the Aconcagua field, and two subsea wells at the Camden Hills field.
