20 kL Diesel Tank Cleaning

Directed the cleaning of a 20 kL diesel fuel storage tank at a remote facility through PT Witanabe. The tank had accumulated sludge and contaminated fuel residue at the base and required full interior cleaning before returning to service. Confined space entry procedures governed the entire operation.

Remote site work removes your safety margin. At a location distant from emergency services, the confined space entry protocol is not a compliance formality. It is the actual emergency response plan. Gas testing before entry, continuous atmospheric monitoring during work, trained standby personnel at the manway, and a rescue procedure that the team has actually practised. Those requirements are the same whether the tank is 1 kL or 100 kL. The 20 kL scale just means more time inside the space, which increases the exposure window.

The tank was returned to service with clean internal surfaces, documented inspection findings, and fuel samples confirming the residual contamination had been cleared. The client's primary concern was timeline. The tank feeds a generator that the facility depends on. Delivering on time at a remote site requires bringing everything the team needs, because there is no resupply if something gets left behind.
