Class-Approved Temporary Underwater Services
MaxiDive Co., Ltd delivers certified and class-approved temporary underwater services for commercial vessels operating across Thailand and the Gulf of Thailand. Our highly trained industrial diving teams provide safe, efficient, and fully documented interventions that comply with international classification society requirements. MaxiDive supports shipowners, fleet managers, ports, and insurers with critical subsea operations designed to minimize vessel downtime and preserve asset value.
Underwater ICCP Replacement
Impressed Current Cathodic Protection (ICCP) systems are essential for controlling corrosion on submerged hull surfaces. MaxiDive performs class-approved ICCP replacement and maintenance using certified procedures and industry-grade components. Our divers assess system integrity, replace electrodes and anodes, and conduct post-replacement verification to ensure optimal corrosion protection. All work is documented with detailed reports suitable for submission to classification societies, insurers, and technical managers.
Sacrificial Anodes Replacement
Sacrificial anodes play a key role in corrosion control on commercial vessels. MaxiDive conducts underwater sacrificial anodes replacement as part of routine maintenance or scheduled dry-dock avoidances. Our certified divers remove spent anodes, install new units, and verify correct placement to maximize cathodic protection efficiency. Comprehensive photographic and video documentation is provided for class, port, and insurance records.
Underwater Welding & Burning (Class Approved)
MaxiDive offers class-approved underwater welding and burning services for urgent repairs and structural corrections below the waterline. Our commercial divers hold qualifications and certifications required to execute hot-work tasks underwater, including welding and cutting on hull plating, brackets, struts, and other critical components. All welding and burning operations are executed in compliance with classification society guidelines and industry safety standards, supported by full technical documentation.
Underwater Hull Repair
From minor dents to more significant hull surface damage, MaxiDive provides reliable underwater hull repair services to restore vessel integrity without unnecessary dry-docking. Our trained divers perform detailed assessments, execute precision repairs, and generate high-definition inspection reports. Repairs are carried out with close adherence to class requirements, ensuring results that meet expectations of shipowners, classification societies, and insurers.
Sea-Chest Blanking & Isolation
Sea-chest blanking (temporary sealing) is a critical procedure during underwater maintenance or emergency interventions when sea intake isolation is needed. MaxiDive’s certified divers perform class-approved sea-chest blanking to prevent water ingress while work is performed. This service is essential during internal system overhauls, cooling system repairs, or when conducting safe inspection work, providing operational security and regulatory compliance.
