Anchor handling is an anchor installation services that assist in the sea
offshore oil drilling operations. Ship and Anchor Handling Tug Supply (AHTS)
vessel is one serving anchor handling services. Work wire is a special equipment
used in anchor handling operations. Such tools make use of machinery auxiliary
hydraulic power powerpack.
The research was conducted during the author implement work practices
in marine AHTS TRITON ARJUNA vessels owned company Triton Global
Maritim and manage by PT Indoliziz Marine for twelve months. Types of writing
using a qualitative and SWOT analysis. Way with the kind of primary data
obtained directly from the research as well as secondary data obtained from the
literature related to the thesis title. Method of data collection is done by direct
observation, interviews conducted by the author to the engineer on board and get
documentation on the results of the study.
From the results of this study indicate that there has been a decline in the
performance of the hydraulic pump powerpack. This is due to the observed
damage to the piston pump and the pump cavitation phenomenon. This causes
symptoms of cavitation erosion cavitation in the valve plate. Then the issue of the
effect on employment than wire work, so the impact on the length of anchor
handling operations. Piston pumps and replacement parts as well as the valve plate
to prevent cavitation done to improve the performance of the hydraulic pump
powerpack.
