The Mahakam Delta in East Kalimantan is crucial for oil and gas exploration in
Indonesia. However, the reliance on a single chart datum (CD) at Handil for sea level
measurements has led to operational disruptions due to the uncertain sea level values.
To address these issues, developing a robust system to better define sea level values is
essential. One effective solution is to build a hydrographic separation model.
The offshore hydrographic separation model is essential for accurately describing and
transforming the positions of tidal datums relative to an ellipsoid. This model is
particularly useful for converting the position of Mean Sea Level (MSL) to Lowest
Astronomical Tide (LAT). In this project, the goal is to create such a model for the area
extending from the Mahakam Delta to Peciko-Bekapai, leveraging Global Mean Sea
Surface (MSS) models and tidal models.
The hydrographic separation model was developed to address the challenges of sea
level uncertainty in the Mahakam Delta, crucial for oil and gas exploration and
maritime operations. The project utilized the CNES CLS2022 MSS model for Mean
Sea Surface (MSS) and the TPXO9v5a tidal model for Lowest Astronomical Tide
(LAT) due to their minimal absolute mean error values. The model was implemented
as a WebGIS application to enhance accessibility and usability. The implementation of
hydrographic separation model as a website application has facilitated real-time,
accurate sea level predictions, greatly enhancing shipping operations and safety. The
product analysis yielded results indicating an 111.94% increase in the frequency of
ship shipping operation windows around the Mahakam area.
