Polar multi-purpose workboat based on ice prying operation

Abstract

The invention provides a polar multi-purpose workboat based on ice skiing operation, the workboat includes a hull body which enables the ship to move on the sea surface, the bow column of the hull main body is inclined to the rear side of the hull, the part of the bow below the design waterline is the same as the X-bow, the acute angle between the longitudinal section line in the bow column and the waterline surface above the design waterline is taken as 30 degrees, and the part of the bow column above the design waterline adopts the concave longitudinal section line. The stern of the hull issquare stern, and the rear side of the square stern is provided with an oil spill recovery door which is provided with an oil spill recovery device, and the bottom of the stern of the ship is providedwith a propeller. The workboad has an efficient operation mode of breaking ice and recovering oil spill backward, and has good open water resistance performance and low fuel consumption rate when navigating in an ice-free area, and can more economically transport necessary materials for an offshore platform in an ice area, and has strong capacity of recovering and treating oil spill on the sea.

Description

technical field [0001] The invention belongs to the field of marine engineering ships, and in particular relates to a polar multipurpose working ship based on ice prying operations. Background technique [0002] Since the beginning of the 21st century, with the rapid development of the global economy and the increasing demand for energy, the pace of exploration and development of offshore oil and gas resources has gradually accelerated. At the same time, with global warming, the Arctic ice is melting year by year, and the ice situation has weakened. Large-scale development of Arctic resources has become a reality. Countries are paying more and more attention to the oil, gas and mineral resources in the Arctic. [0003] Polar regions are rich in oil and gas resources. It is estimated that the potential recoverable oil reserves in the Arctic region are 100-200 billion barrels, natural gas is 50-80 trillion cubic meters, and the recoverable natural gas resources in northern Sib...

Problems solved by technology

However, in order to improve the ice-breaking capability, the traditional gravity-type ice-breaking bow with full forward tilt is usually adopted, and the bulbous bow is no longer set at the bow. Difficult to meet

At the same time, in order to improve the transportation capacity of the multi-purpose offshore engineering ship, its own square coefficient and Froude number are relatively large, and the resistance performance will be further deteriorated after the ice-breaking bow is fully tilted forward.
