Tank maintenance & Treatments
Maintaining tank integrity and operational reliability
Tank maintenance focuses on assessing the real condition of onboard tanks and applying targeted protection measures to preserve structural integrity and operational reliability. A planned and controlled approach helps reduce downtime, prevent unexpected issues and avoid scope and budget overruns during dry dock.
Technical inspection
Assessment of tank condition and coating integrity
Surface preparation
Cleaning and preparation of tank surfaces prior to treatment
Localised repairs
Targeted structural and anticorrosion interventions where required
Protective coatings
Application of certified coating systems suited to tank type and use
Quality control
Final inspections, detailed reporting and complete technical records
Tank control plan
Assessing condition, planning protection and reducing operational risk
The Tank Control Plan is a planned maintenance system designed to manage the condition of onboard tanks over time, rather than reacting to isolated issues during dry dock periods or unexpected inspections.
It provides a clear and controlled framework to assess tank condition, define priorities and schedule maintenance actions in a predictable manner. By shifting from reactive interventions to planned monitoring, the Tank Control Plan supports better preparation, improved coordination and more efficient use of maintenance windows.
Objectives & Benefits
- Planned cost control.
Clear budgeting through scheduled inspections and defined maintenance scopes.
- Reduced unplanned dry dock time.
Early identification of issues avoids last-minute interventions and delays.
- Service available across the Mediterranean.
Consistent execution supported by multiple operational bases and mobile teams.
- Higher coating quality, reduced maintenance frequency.
Timely interventions extend coating life and reduce the need for repeated works.
- External technical management support.
Ongoing support for the Captain, Chief Engineer and Yacht Manager throughout the maintenance cycle.
How the Tank Control Plan works
- Reduced dry dock uncertainty.
Clear visibility of tank condition before entering dry dock.
- Controlled scope definition.
Fewer unexpected scope changes and budget deviations during execution.
- Improved coordination.
Aligned communication between crew, surveyors and shipyards.
- Informed decision-making.
Up-to-date tank condition data supporting timely maintenance actions.

Quality control at every underwater stage
What sets us apart is the application of measurable and verifiable Quality Standards through our own management model, the NautiStandard — specifically adapted for underwater and corrosion-critical operations.
The NautiStandard is built on a comprehensive system of controls, inspections and performance tests carried out throughout every phase of underwater works, from surface preparation to final coating application.
These procedures ensure that each stage meets strict technical criteria, guaranteeing long-term protection, structural integrity and reliable performance below the waterline.
This model is based on the principles of ISO 9001 and aligned with the technical guidelines of ICOMIA.
Our standards go further, incorporating stricter internal protocols specifically developed for corrosion control, surface preparation and underwater coating systems.
