Based in Singapore, Master Tech Diving Services Pte Ltd is a specialist provider of commercial diving and marine engineering solutions, supporting the global shipping, offshore oil and gas, and submarine cable industries. Established in 1994 by Steven Tan, a figure deeply rooted in the local diving sector, the company has operated for over three decades, evolving from a diving contractor into a comprehensive underwater service organization. Currently led by a second generation of management, the firm maintains its headquarters in the Tuas industrial district, a strategic location that facilitates rapid deployment to vessels and marine structures throughout the region.
The company’s core operations focus on underwater ship maintenance and repair, services critical for maintaining vessel efficiency and meeting regulatory standards. Recognizing that biofouling on hulls and propellers significantly increases drag and fuel consumption, Master Tech performs mechanical underwater hull cleaning and propeller polishing. These activities are designed to restore hydrodynamic performance without the need for dry-docking. Beyond routine cleaning, the company conducts detailed underwater inspections, including Underwater Inspection in Lieu of Dry-docking (UWILD), which allows shipowners to satisfy classification society requirements while the vessel remains afloat. The firm holds approvals from major classification societies, enabling its divers and technicians to certify the structural integrity of ships through visual checks and non-destructive testing methods like ultrasonic thickness measurement.
In addition to ship husbandry, Master Tech Diving Services Pte Ltd plays an active role in the civil engineering and offshore energy sectors. Its teams execute complex underwater construction and repair tasks, such as hyperbaric welding, cutting, and the installation of cathodic protection systems to prevent corrosion. For port infrastructure, the company inspects and maintains wharves, jetties, and piling systems, ensuring the longevity of coastal assets. The organization also supports the submarine cable industry by assisting with cable laying, burial, and protection, as well as providing support for offshore oil rigs and platforms.
To execute these varied missions, the company utilizes a workforce of certified commercial divers and deploys specialized equipment, including Remotely Operated Vehicles (ROVs) and hydraulic brush karts. Maintaining a twenty-four-hour operational readiness, Master Tech mobilizes personnel and gear across the Asia Pacific and Middle East regions, addressing both scheduled maintenance and emergency salvage or repair requirements for international maritime clients.
