Testing of SHHP Anchors
Anchor Proof Test
The SHHP anchor is to be proof tested with the load required by Table 2 for an anchor mass equal to 2 times the actual mass of the SHHP anchor. The proof loading procedure and examination procedure for SHHP anchors are to comply with those for ordinary anchors,
Anchor inspections and Additional Tests
After the proof load test, all SHHP anchors are to be surface inspected by the dye penetrant method or by the magnetic particle method. All surfaces of cast steel anchors are to be surface inspected. The surface inspections are to follow Guidelines for NDE of Hull and Machinery Steel Castings. All cast steel anchors are to be examined by UT in way of areas where feeder heads and risers have been removed and where weld repairs have been carried out.
The UT inspections are to follow Guidelines for NDE of Hull and Machinery Steel Castings. Welded steel anchors are to be inspected at the welds.
At sections of high load or at suspect areas, the Society may impose volumetric nondestructive examination; e.g ultrasonic inspection, or radiographic inspection.
At the discretion of the Society, additional tests of the anchor may be required. These tests include the hammering test and the drop test, and are usually applied to cast steel anchors.
