The article presents a study which examines the spectrum of embedded suction anchors (ESA) for mooring of a floating breakwater which is being built in southern Korea as part of the Wonjeon Harbor reconstruction plan. ESA is a type of permanent offshore foundation that is installed through a suction pile with the same diameter that is used to drive it into the sea floor. The design loading capacity of embedded suction anchors was validated by subsequent proof test.

This article focuses on the line of draw warper beams being offered by Korea-based Hyung Jae Precision Machinery Co. Ltd. for Raschel & Tricot machines. The flanges of the forged beams are made of high strength aluminum alloy and manufactured by high pressure forging press, and so it has excellent rigidity and durability. The barrel as an extruded pipe of heat-treated aluminum has high strength and precision. The welding is done with a high precision automatic welding method by ROBOT system. Because of dynamic balancing function, a good compatibility with weaving loom is maintained in spite of high-speed rotation. Through hard anodizing coating treatment, corrosion and surface scratching are entirely prevented. Durability and precision are maintained even after several years' utility.
