Split Tank Retrofit for NOAA Research Vessel

Customer Overview

Our customer, a NOAA vessel, required an upgrade to replace their aging and rusted competitors system that was no longer serviceable. The goal was to install a new FAST® (Fixed Activated Sludge Treatment) to improve operational efficiency and reliability at sea.

The Problem

During the pre-sales process, it became clear that the vessel’s existing hatch openings were too small to accommodate the new MSD by Scienco/FAST® as a single unit. The confined space within the vessel’s structure prevented standard installation methods, making it impossible to bring the MDS assembly aboard in one piece. Traditional solutions – such as cutting larger hatch openings or using smaller, less capable equipment – were not acceptable due to cost, time, and vessel integrity concerns.

The Solution

To overcome this challenge, our engineering team developed a custom split tank design. The MSD was divided into two separate sections that could be individually transported through the vessel’s exiting hatches. A gasketed flange system was incorporated, allowing the two halves to be securely reassembled once inside the installation space. This approach maintained the full functionality and performance of the Scienco/FAST® MSD while meeting the tight spatial constraints of the vessel.

The Results

• The split tank system was successfully installed without any structural modifications to the vessel.
• The retrofit was completed efficiently and on schedule
• The NOAA team now operates with a modern, corrosion-resistant system designed for long-term durability and serviceability

Key Takeaway

Through innovative engineering and customer design, we delivered a practical retrofit solution for the marine environment where space limitations often complicate equipment upgrades. The split tank design not only solved the installation challenge but also demonstrated our commitment to adaptable, customer-focused problem-solving.
