Underwater Maintenance & Repairs

Blanking of Sea Valves

Blanking of sea chests/plugging of intakes or overboard discharges to assist with inboard repairs. This is a very cost-effective method of changing defective valves and repairing sea chest plating, while afloat during normal ship operations.

Utilizing our extensive array of blanks consisting of solid flat aluminum patches, flexible solid back eductor mats, vacuum boxes, and a large assortment of mechanical and inflatable plugs we can seal off any size or configuration of sea inlet or overboard discharge with ease.

It is an advanced and high-risk underwater service but also especially important for the vessel. The first leg of the work is to remove the Thruster and after the repairs to proceed with the underwater installation.
