Stern Seal Replacements Without the Downtime

Engineered for Precision. Delivered with Speed.

Every stern seal repair project begins with a detailed assessment of the seal system, liner condition, and vessel operating requirements. Our modular cofferdam systems allow us to safely isolate the shaft and perform full seal replacements without the delays and expense of dry docking.

From bonding and profiling to liner inspections and shaft runout measurements, every repair is executed with precision and quality control—so you can trust the results.

Anywhere, Anytime. No Dry Dock Needed.

With offices in over 14 locations and rapid mobilization capabilities, our teams are equipped to deliver seal replacements wherever your vessel is berthed. Whether it’s a commercial port, offshore anchorage, or industrial terminal, we bring the expertise and equipment to you.

We support critical operations with minimal disruption and flexible scheduling—day or night.
