Comprehensive Underwater Support for Vessels, Rigs & Offshore Assets

At Aroona Shipcare, we complement our lay-up and shipcare programs with specialised Underwater Support Services designed to maintain, inspect, and repair your asset without the need for drydocking. Through our trusted group partners and certified commercial diving teams, we provide a full suite of underwater operations—including UWILD, hull cleaning, underwater inspection, repair works, and critical maintenance to ensure structural integrity and regulatory compliance.

​

Whether your vessel is in lay-up, preparing for reactivation, or engaged in ongoing operations, our underwater services help reduce downtime, avoid costly dockyard delays, and maintain the long-term health of your hull and underwater structures.
