A trailer jacking system includes a trailer that has a pair of axles, a first lateral side and a second lateral side. A pair of bars is provided and each of the bars is coupled between each of the axles. A jack is selectively positioned beneath the bars for jacking the trailer. Each of the bars is oriented collinear with an associated one of the first and second lateral sides. In this way each of the bars facilitates the trailer to be leveled between the first and second lateral sides when the trailer is jacked. A plurality of u-bolts is provided and each of the u-bolts bolts is coupled between the bars and an associated one of the axles to retain the bars on the axles.

A control system detects a loaded state for a lifting device. The control system receives a current load value from a load sensor corresponding to a load on the lifting device and compares the current load value from a previously received load value to determine a change in load. The control system receives a current displacement value from a displacement sensor corresponding to a displacement of the lifting device and compares the current displacement value with a previously received displacement value to determine a change in displacement. The control system compares the change in load with the change in displacement to determine a current load slope. The lifting device in identified in a loaded state based on a comparison of the current load slope with a load slope threshold. The control system may stop extending the lifting device after reaching the loaded state and start extending all of the lifting devices in unison to lift the load off of a base surface after all of the lifting devices reach the loaded state.

An underwater operation platform, including: a main body; two ducted propellers disposed at the tail end of the main body; a living building; pile legs; a tower crane; a submergence module; lifting devices; and a gantry crane. The main body includes a deck and a moonpool. The submergence module includes a support plate, a plurality of truss members, and a base plate. The living building disposed on the front end of the deck. The pile legs are disposed at the four corners of the main body, respectively. The deck includes two parallel pathways which are located at two sides of the moonpool, respectively, for supporting the gantry crane. The lifting devices are disposed on the deck and are close to four corners of the moonpool. The support plate and the base plate are integrated with the plurality of truss members.
