In-Water Survey LNG Tanker Thailand Using Real-Time CCTV Inspection

LNG tanker under Thai flag during in-water survey inspection in Thailand

In-Water Survey LNG Tanker Thailand – Project Overview

MaxiDive successfully completed an in-water survey (UWILD) on an LNG tanker under the Thai flag, with live inspection footage transmitted in real time to representatives of the Thai Marine Department.

The inspection was conducted using a professional CCTV system, enabling immediate evaluation of hull condition, marine growth, and structural integrity without dry docking.

In-Water Survey LNG Tanker Thailand – Key Findings

The inspection covered the full underwater hull including bow, flat bottom, bilge areas, propeller, rudder, and sea chests.

Key observations:

• No structural damage or contact deformation detected

• Hull coating condition generally good (≈80% remaining)

• Soft marine growth up to 95% coverage

• Hard marine growth (barnacles, oysters) up to 30–100 mm

• Sacrificial anodes active but significantly depleted (50–95%)

• Propeller and rudder in good condition with no major damage

These findings highlight the importance of timely maintenance supported by services such as Hull Cleaning Services, which help remove marine growth, restore hull performance, and prevent increased fuel consumption and operational inefficiencies.

In-Water Survey LNG Tanker Thailand – Inspection Process

The inspection included:

• Bow and bulbous bow assessment

• Hull surface condition analysis

• Bilge keel and flat bottom inspection

• Propeller and rudder detailed examination

• Sea chest and rope guard inspection

All findings were verified in real time via CCTV transmission  as part of our UWILD Inspection.
