Hull Cleaning & Underwater Marine Growth Removal Services
MaxiDive provides industry-leading hull cleaning services across Thailand and the Gulf of Thailand.
Marine growth, barnacles and aquatic fouling significantly increase drag and fuel consumption, reduce speed, and shorten coating life. Our commercial hull cleaning services are executed by certified industrial divers using state-of-the-art hydraulic cleaning systems with flexible rotating shafts and rubber-based brushes — enhancing cleaning performance while protecting antifouling coatings.
Surface cleaning is tailored to vessel type and operating profile, helping owners improve fuel efficiency, meet regulatory compliance and reduce unplanned downtime. MaxiDive’s hull cleaning programs operate in all major Thai ports including Laem Chabang, Sattahip, Sriracha and Bangkok Port, delivering safe, efficient and cost-effective underwater maintenance.
Key benefits:
-
Enhanced vessel performance and speed
-
Lower fuel consumption and emissions
-
Extended antifouling coating life
-
Safe underwater execution without dry-docking


Propeller Polishing
& Repair Services
Efficient propulsion depends on smooth, hydrodynamically optimized propeller surfaces.
Even minor surface roughness on propeller blades can lead to vibration, increased fuel usage, engine stress and reduced thrust. MaxiDive’s propeller polishing and repair services use multi-stage polishing with diamond discs to achieve near-Rupert scale “A” finishes. Our certified divers perform detailed inspections, micro-polishing, static balancing and corrective repairs.
Every project includes photographic documentation and written reports suitable for class, insurance and technical review — ensuring propeller optimization and long-term efficiency gains.
In-Water Survey / Post Grounding Inspections / UWILD
Underwater inspections are a core part of proactive vessel maintenance and damage assessment.
MaxiDive delivers professional in-water survey (UWI) and post-grounding inspection services for commercial vessels. Our certified divers use closed-circuit television (CCTV) and HD video to capture condition data, enabling shipowners and classification societies to effectively review hull integrity, structural components and underwater appendages.
Inspection files include measurements and footage that support class surveys, insurance claims and technical decision-making. These services minimize the need for dry-dockings and provide precise insight into underwater condition and performance.


Class Approved Temporary and Permanent Repairs
MaxiDive performs class-approved underwater repairs and temporary maintenance.
Our certified industrial divers are equipped to undertake:
-
ICCP (Impressed Current Cathodic Protection) system replacement
-
Sacrificial anodes replacement
-
Underwater welding and burning (Class approved)
-
Hull repair / structural correction
-
Sea-chest blanking and intake isolation
All repair procedures are executed in accordance with major classification society standards and accompanied by detailed reports and photographic evidence for submission to class, insurers and port authorities.
Internal Ship Repair Services
MaxiDive’s internal ship repair capabilities support complex underwater mechanical work.
Our specialised internal ship husbandry team performs a variety of critical tasks without the need for dry-docking, including:
-
Underwater valve removal and installation
-
Seal replacements and gasket installation
-
Internal system adjustments during anchorage or port operations
Each intervention is executed by certified commercial divers using industry-grade tools and best practices to ensure safety and operational continuity.


New Zealand (MPI) / Australia & USA Marine Inspections
MaxiDive offers specialised Marine Performance Inspections (MPI) aligned with international guidelines such as the Craft Risk Management System (CRMS) used in New Zealand and similar programs in Australia and the USA.
MPI services assess hull condition and fouling levels in adherence to regional regulatory standards, providing fleet operators with timely condition reports that streamline compliance and vessel readiness.
Surface Husbandry Services
Surface husbandry is a targeted maintenance service focused on shallow waterline areas.
MaxiDive’s surface husbandry integrates heavy-duty hull cleaning with targeted removal of marine fouling above and near the waterline. These services improve hydrodynamic performance, extend coating life and prepare vessels for inspections or dry-docking sequences.
Surface husbandry includes comprehensive marine growth removal supported by a fully equipped surface husbandry team with fabrication and lifting capabilities.
