A deck plate extension for a row unit of an agricultural harvester. The deck plate extension configured to attach to the return side of the row unit side thereby preventing a kernel crop from dropping to the ground during harvesting. The deck plate extension is further provided with a kernel channel configured to direct the kernel crop along the return side of the row unit side to the harvest side of the row unit side. The deck plate extension may be provided as part of a deck plate of a row unit side or may be provided as a second plate added to the row unit side. The deck plate extension is configured to be added as original equipment and as a retrofit to existing row units.

The invention discloses a method for integrally renewing a deck of an oil tanker in a floating state, which comprises the following steps of: a, carrying out staged design on a renewing area of the deck of the original tanker, and carrying out overall strength and load regulation calculation according to the staged design; b, designing new deck subsection division according to the staging design; c, according to a load regulation calculation result, pumping ballast water into a ballast tank in the middle area; d, installing a first-stage new deck segment, and adjusting the deflection of the deck; e, installing a second-stage new deck segment, and adjusting deflection; f, installing a third-stage new deck segment, and adjusting deflection; g, installing a fourth-stage new deck segment, and adjusting deflection; and h, after welding of the transverse segmentation joints and the longitudinal segmentation joints of the fourth-stage deck is finished, finishing replacement of the whole deck replacement area. According to the deck replacement process method for the oil tanker in the floating state, the problem that the oil tanker occupies a large dock period to replace a deck is solved, the dock period is saved by 35-40 days, and the competitiveness of a company is greatly improved.

The invention relates to a LNG gas ventilation mast for a ro-ro passenger ship, which comprises a barrel, a first ventilation pipe and a second ventilation pipe, and the barrel inclines towards the stern direction and is fixedly installed on an exposed deck and provided with a first channel and a second channel which are spaced from each other and extend in the length direction. The top of the first channel and the top of the second channel are provided with a ventilation net and a rainproof cover, the first channel is divided into a plurality of cavities which are separated from one another, the size of the cavities is in positive correlation with the caliber of the first ventilation pipe, the caliber of the second ventilation pipe is smaller than that of the first ventilation pipe, and the diameter of the second ventilation pipe is smaller than that of the second ventilation pipe. The first vent pipe penetrates out of the exposed deck and then extends by a preset length in the cavity, and the second vent pipe penetrates out of the exposed deck and then extends to the top in the second channel. The internal structure is reasonably divided, the structure is compact, the occupied space is small, and functionality and attractiveness are both considered.
