In-Water Surveys: A Cost-Effective Solution for Ship Management

Traditional dry-docking for hull inspections involves significant expenditures and unavoidable vessel downtime. However, there exists a highly efficient and budget-friendly alternative with widespread gains in popularity: in-water surveys. Through this technique, critical assessments of a ship’s condition take place beneath the waterline, while the ship remains operational. Let’s explore how in-water surveys transform ship management processes in West Africa and the broader maritime world.

What In-Water Surveys Entail

In-water surveys utilize diverse methods for comprehensive visual hull assessments. Some key components commonly observed during these specialized surveys include:

  • Hull Structure: Detailed survey of the hull for signs of damage, corrosion, excessive wear, or areas where coatings require remediation.
  • Propellers and Propulsion Systems: Inspection of propellers, rudders, shafts, and associated components for damage and fouling buildup.
  • Intakes, Sea Chests, and Anodes: Assessment of seawater intake systems, grating condition, and the status of sacrificial anodes protecting against corrosion.
  • Other Appendages: Visual observations of stabilizers, thrusters, and any other external hull-mounted systems or machinery.

Technological Tools Enhancing In-Water Surveys

In-water surveys leverage a range of specialized equipment to capture thorough evaluations:

  • Skilled Dive Teams: Teams of expertly trained divers with experience in ship inspections carry out visual assessments utilizing lights, measurement tools, and reporting mechanisms.
  • Underwater Photography and Videography: Real-time documentation of findings with photos and high-definition footage for review and reporting.
  • Remotely Operated Vehicles (ROVs): Deploying ROVs equipped with powerful cameras and imaging capabilities assists surveys in complex or challenging areas.

Reaping the Rewards of In-Water Surveys

The benefits of shifting from solely relying on dry-docking for inspections are substantial. The strategic use of in-water surveys unlocks:

  • Cost Savings: In-water surveys eliminate the expenses associated with dry-docking, potentially translating into thousands of dollars retained while preserving revenue generation.
  • Minimized Downtime: Inspections take place without removing a vessel from service, keeping your maritime assets actively engaging in profitable operations.
  • Increased Flexibility: Surveys can be scheduled strategically within operational parameters and in geographically convenient locations.
  • Regulatory Compliance Support: Regular in-water surveys support vessel adherence to classification society requirements and port regulations.
