The invention discloses a
lofting production method of an anchor recess of a planking thickness line of a
hull. The
lofting production method comprises the following steps: (1) line type
lofting of an anchor recess region adopts a method of deducting the planking thickness line of the
hull; (2) the line type of the anchor recess takes an A-A section of a center line of a hawse
pipe as a reference, and projection is carried out on a three-directional line type deducting the planking thickness; (3) the protection of a section of an anchor mouth takes a 7# section and a 3# section of the center line of an anchor
pipe as reference, and an origin of the outlet of the anchor
pipe is a constant value; (4) the center line of the anchor pipe and a rib position of a water line are marked on a tapping sample; (5) the anchor mouth is located on the outlet point of the anchor pipe of the planking of the
hull; (6) values are reasonably corrected by a cat anchor test; (7) the anchor recess is installed. According to the lofting production method, the validity and the success rate of the cat anchor test are improved, the design quality is improved, the production cost is reduced, the
production cycle is shortened, the production design is matched with a production method of a
production department, so that anchor release, anchor raise and
mooring of a ship can be successfully carried out after the anchor recess is installed.
