Ship’s mooring and towing fittings –Welded steel bollards for sea-going vessels.
ISO 13795:2012
Materials
Plates:weldable steel plates having a yield point of not less than 235N/mm2. Post tubes:weldable steel plates having a yield point of not less than 235 N/mm2 or equivalent steel tubes.Manufacturing and inspection
All surfaces of the bollards including welding shall be free from any visible flaws or imperfections. All surfaces in contact with the ropes shall be free from surface roughness or irregularities likely to cause damage to the ropes by abrasion. The bollards shall be coated externally with an anti-corrosion protective finish. A low-friction surface coating is not recommended so as to increase the holding force of the mooring ropes under figure-of-eight belay.Type
Type A :with compact base plate.
Type B:with wide base plate.
