Long shafting arranging and installing method of platform work ship

Abstract

The invention discloses a long shafting arranging and installing method of a platform work ship. The long shafting arranging and installing method of the platform work ship includes the following steps that a base line of a ship body is assigned, and other auxiliary lines which are parallel to the base line are pulled out; axis centering is performed with an irradiation method, an irradiation datum point of a shafting theory center line is determined, and a shafting primary pulling line and a tail shaft irradiation datum point are determined; a dummy shaft is used for simulating a tail shaft to perform primary shafting arranging and installing; the position of a reduction gearbox is determined according to a shafting positioning datum line, the dummy shaft and the reduction gearbox are centered, and the position of a high-speed transmission shaft and the position of a main machine are determined in the direction from the gearbox to a ship head; the high-speed transmission shaft is centered and installed; the main machine is centered and positioned, the position of the main machine is accurately adjusted, axial, radial and zigzag numerical values of a flange of the high-elastic and high-speed transmission shaft of the main machine conform to specified values. The long shafting arranging and installing method of the platform work ship is reliable, easy to perform, and capable of improving the installation efficiency and improving the shafting installing precision.

Description

technical field

[0001] The invention belongs to the technical field of ship engineering, and in particular relates to a method for arranging and installing the length shafting of a platform working ship. Background technique

[0002] With the development of offshore oil platforms, the demand for platform workboats that provide various characteristic operation services for offshore oil projects is gradually increasing. The platform workboat needs to be able to cruise near the offshore oil platform, be able to carry out anchor handling operations and haulage operations of platforms and large barges, and have first-class external fire-fighting and fire-fighting capabilities, sea surface oil pollution removal capabilities, and rescue operations capabilities. Pick up rescued people. And carry out towing and fishing oil pipeline operations on the oil storage ship and the arriving oil pick-up ship, and assist them to carry out oil pick-up. This type of operation requires ships to...
