Muhammad, Fahmi Pratama. 2025. "Handling of Low Sulphur Waxy Residue LSWR
Cargo When Solidified in the Marpol Line After Discharge Process on MT. Sanggau"
Low Sulphur Waxy Residue (LSWR) is a type of petroleum cargo produced from crude
oil distillation with a low sulfur content, characterized by its tendency to solidify under
48°C, especially when not handled with proper post-discharge procedures. This study
aims to analyze the handling of LSWR solidification that occurs in the Marpol line after
the discharge process on MT. SANGGAU. A qualitative descriptive method was
employed, with data collected through direct observation, interviews with ship officers,
and documentation during sea practice. The findings show that the solidification of
LSWR was caused by the incomplete drying of the Marpol line, worsened by limited
operational time and a lack of coordination between the ship and the terminal. In addition,
corrective action in the form of manual cleaning was found to be inefficient, timeconsuming, and posed a high safety risk. Therefore, the recommended solution is the
installation of a heating coil system on the Marpol line, along with adjustments to the
operational schedule to allow for optimal drying procedures. The implementation of this
solution is expected to improve both the efficiency and safety of cargo discharge
operations on oil tankers.
