J. Underwater Engineering and Marine Technical Services

Based in the industrial port city of Tema, Ghana, J. Underwater Engineering and Marine Technical Services functions as a specialized provider of subsea and general marine solutions within the West African maritime sector. Established in 2007, the company was formed to address the growing demand for professional commercial diving and vessel husbandry services along the Gulf of Guinea. Over the years, it has expanded its operational footprint to support commercial shipping, port authorities, shipyards, and the offshore oil and gas industry, conducting operations in key regional hubs such as Takoradi and Tema. The company’s core expertise lies in underwater engineering, where it deploys teams of certified professional divers to execute complex tasks below the waterline. A significant portion of its daily operations focuses on vessel maintenance and performance optimization. This includes underwater hull cleaning and propeller polishing, services critical for reducing hydrodynamic drag and improving the fuel efficiency of merchant vessels. Additionally, the firm conducts sea chest cleaning and anode replacement, ensuring that cathodic protection systems remain effective against corrosion. Beyond routine maintenance, J. Underwater Engineering and Marine Technical Services performs detailed underwater inspections and surveys. Utilizing closed-circuit television (CCTV) and high-resolution photography, technical teams assess the structural integrity of hulls and submerged infrastructure. These in-water surveys are conducted in accordance with the rigorous standards set by major international classification societies, such as the American Bureau of Shipping (ABS), Lloyd’s Register, and Bureau Veritas. This compliance ensures that vessel operators can meet regulatory requirements without dry-docking. The organization also provides technical repair capabilities, including underwater cutting, wet welding, and waterproofing services. While its primary focus remains subsea intervention, the company’s scope extends to general marine engineering, encompassing marine electrical and mechanical works. Operations are governed by a strict internal diving safety manual and environmental policies designed to mitigate risks to personnel and the marine ecosystem. By integrating diving proficiency with technical engineering skills, the company serves as a support node for the regional maritime logistics chain, facilitating the continuous operation of vessels trading in West African waters.
