In this study, we report a fluorescent probe (CBT) for detecting SO2 derivatives in ratiometric fluorescence manner.

A simple but effective fluoresecent probe for the detection of bisulfite based on Michael addition reaction.

It is common to use the shuttle tanker to transport the oil in the marginal oilfield development. However, a reused shuttle tanker needs to reappraise its mooring safety. For certain water depth, after considering the various directions of wind and wave, a comprehensive analysis should be done on the mooring force of the shuttle tanker mooring system. We use different seed value waves and quasi dynamic analysis method to determine the shuttle tanker limit operating condition by changing the environmental parameter. The result shows that when the included angle of the horizontal projection of two chains and the direction of tanker length is 30 °, the mooring force of the mooring system is smaller than when it is 60 °. At the same time, in the case of 11.8 meters depth and 1.74 meters wave height, the tanker is unable to meet the requirements of safety operation. After step by step analysis, tanker mooring system can guarantee the safe operation when the wave height is no more than 0.6 meters, so as to accord with the safety operation condition.
