Seiso Indonesia operates as a specialized industrial service provider known principally for its expertise in maintenance, cleaning, and engineering support within the energy and maritime logistics sectors. Legally incorporated as PT Suci Energi Solusi Indonesia, the company was established in 2013. Its name is derived from the Japanese 5S methodology term Seiso, translating to neatness or shine, which underpins its operational focus on industrial hygiene, decontamination, and asset integrity.
The company functions as a critical support entity for the maritime, oil and gas, and petrochemical industries. Its primary relevance to the marine sector lies in its comprehensive tank cleaning and maintenance solutions. Seiso Indonesia deploys teams to execute high-stakes cleaning operations for fuel oil (FO) and lube oil (LO) tanks, cargo holds, and storage vessels. These services are essential for ensuring that ships and port terminals maintain cargo purity, prevent cross-contamination, and adhere to strict safety regulations regarding hazardous waste. Beyond standard cleaning, the company provides sludge oil recovery services, utilizing technology to separate oil, water, and solids to recover usable hydrocarbons from marine and industrial sludge.
In addition to vessel and tank care, Seiso Indonesia manages infrastructure that directly interfaces with maritime operations. The company performs maintenance on jetty pipelines, employing methods such as pigging and high-pressure water jetting to clear blockages and ensure the efficient transfer of liquid bulk cargo between vessels and shore facilities. Its portfolio includes engineering projects for major energy distribution terminals and petrochemical plants, where it handles tasks ranging from catalyst loading and unloading to column decontamination and coating.
In 2025, the company underwent a significant corporate development by becoming a member of the PT AJK Group (AHA Jaya Kontruksi), a holding entity focused on engineering, procurement, and construction (EPC). This integration aligned Seiso Indonesia with a broader network of infrastructure firms, expanding its capacity to deliver large-scale maintenance solutions. Through its certified management systems and specialized workforce, the company sustains the operational readiness of storage and transfer assets across the Indonesian archipelago.
