Efficiency Analysis of the Deck Boiler on FPSO Marlin Natuna Vessel of Vertical Water Tube Marine Type According to ASME PTC-4 Standard

Abstract:

The FPSO Marlin Natuna is the first conversion vessel in Indonesia to be transformed from an FSO to an FPSO, equipped with various facilities for processing crude oil and gas from the Forel and Bronang wellhead platforms (WHP). One of the most critical facilities is the deck boiler with a capacity of 25 tons per hour, which functions as the driver for two crude oil pump units, one ballast pump unit, and to maintain the temperature stability and inert gas condition in the cargo oil tank. This study aims to analyze the efficiency of the dual-fuel deck boiler (diesel and gas) on the vessel. Testing was conducted based on the ASME PTC 4-2013 standard using the direct method during the commissioning phase. Test data were obtained at a maximum load of 40% (diesel) and 50% (gas), including steam and fuel flow rates, steam pressure and temperature, and other test parameters. The data were analyzed to determine the deck boiler efficiency by comparing the output energy to the input energy. Results showed that the deck boiler efficiency was 74.94% with diesel fuel and 63.63% with gas fuel, with a diesel consumption of 632 kg/h and gas consumption of 627 kg/h. These findings are expected to serve as a basis for evaluation efforts aimed at improving the deck boiler system efficiency on the FPSO Marlin Natuna.
