As the radial distance from the wellbore increases, pressure drawdown and upward dynamic force decrease, and the height...

.... The calculation results show that the ship operates at a speed of 10 knots to 11 knots, which can maintain a relatively high speed and profitable status, but also to achieve a lower level of CO 2 emissions from ships. However, this method of finding the best balance point of ship's speed and fuel consumption...
