Failure analysis of sea water cooling pump's shaft (SWCP) on board anchor handling tug supply (AHTS) Abdul Hamid, Sri Nugroho, Gunawan Dwi Haryadi, Agung Nugroho Aip Conference Proceedings, 2019 The pump shaft generally exposed either to liquids, which pumped continuously, or in certain locations along the shaft. The shaft material is Duplex Stainless Steel AISI 329H (UNS S32900). The purpose of this study is to determine the failure of the seawater pump shaft used in the engine cooling system on the ship anchor Handling Tug Supply (AHTS). Visual observation is the study of SWCP (Sea Water Cooling Pump) shaft material. The SEM test used to determine the initial crack (crack initiation). The EDS test used for chemical composition and the Brinell Hardness Tester hardness test also used to determine material hardness. Voltage analysis used to find out how much load received by the shaft. These five tests support in analyzing pump shaft failure. The conclusion of this failure analysis is that the shaft material has porosity. Fatigue cracks originate from the outer surface area of the shaft.The pump shaft generally exposed either to liquids, which pumped continuously, or in certain locations along the shaft.

Failure analysis of shaft circulating water pump (CWP) used in power plant Abdul Hamid, Sri Nugroho, Gunawan Dwi Haryadi, Khaeroman Matec Web of Conferences, 2018 Pump shafts are generally exposed to the liquid being pumped either on a continual basis or at certain locations along the length of the shaft. The shaft material is austenitic stainless steel, description ASTM AU 79 TY 316. The purpose of this study is to determine the failure of the water pump shaft used in the power plant. Metallography is the study of structure metal shaft can used as a means for CWP metal pelleting (Circulating Water Pump), for the purpose of damaged or deeply degraded areas. SEM test is used to know the beginning of the crack (crack initiation). EDS test is used to chemical composition and Vikers hardness test is also used to know the hardness material. These three tests to support in analyzing the failure of the pump shaft. The conclusion of this failure analysis is the shaft material has porosity. Fatigue cracking comes from the outer surface area.
