New Tool For Marine Geology
The Chelsea Technologies Group has recently delivered a Nu-Shuttle system specifically configured for marine geology applications. Working with Sequoia Scientific (Bellvue, WA) a redesigned compact version of the LISST 100x instrument has been installed in the NuShuttle undulating towed vehicle. This is complimented with a Sontek MiniADP, OBS3+ optical backscatter sensor and MINIpack CTD-fluorimeter package. The system will be towed behind a survey vessel enabling real time profile of suspended sediments throughout the water column. The standard LISST 100x, redesigned into two smaller pressure housings resulting in a more compact
unit with better flow orientation, provides real time data on particle size distribution and volume concentration. The Sontek ADP 1.5 MHz was selected due to its small, compact size and ability to provide water current data during the survey.

COOEC Chooses New ROVs
In a major breakthrough into the Chinese oil and gas industry, Saab Seaeye has sold two Panther Plus electric work ROVs to China's largest off-shore engineering company, COOEC. It follows an earlier sale of a Panther Plus and represents an expanding capability for COOEC who are part of China National Oil. Of the two vehicles sold to the Chinese off-shore company, one will operate from a Tether Management System, while the other is free-swimming. Technical support will come from Saab Seaeye's distributor in the region, Blue Whale Offshore Engineering Technology Company. The ROV can cut wire rope and soft line up to 1.5 inch (38mm). It can carry out visual operations with high quality video systems. Perform pre and post drilling site survey. Undertake guidance and orientation for BOP and riser connection, depth and orientation of wellhead and BOP stack. It can also clean wellhead and bulls eyes, and change out AX wellhead gaskets.
