Global Marine Heritage operates as a specialized provider of commercial diving and subsea engineering services, functioning as a key technical resource within the West African maritime sector. Established in 2021, the company maintains its primary operational base in Conakry, Guinea, while simultaneously conducting activities through facilities in Lagos, Nigeria. This dual foothold allows the firm to service a broad range of maritime needs across the Gulf of Guinea, supporting both inland waterways and offshore environments.
The core of the company’s operations revolves around ensuring the structural integrity and operational efficiency of marine assets. Through a combination of professional divers and remotely operated vehicles (ROVs), Global Marine Heritage executes complex underwater tasks that are essential for the maintenance of commercial fleets. A significant portion of its workflow addresses vessel performance; the company provides comprehensive hull cleaning and propeller polishing services designed to remove marine growth. By mitigating the drag caused by biofouling, these maintenance interventions directly contribute to improved fuel economy and reduced emissions for shipping lines calling at regional ports.
Beyond routine vessel maintenance, the company engages in heavy marine construction and civil engineering projects. Its technical teams are equipped to handle underwater welding, cutting, and the placement of concrete structures, capabilities that are critical for port infrastructure development and repair. The organization also supports the offshore oil and gas industry by conducting subsea inspections of pipelines and platforms. Utilizing non-destructive testing (NDT) methodologies and advanced sonar imaging, the firm assesses the condition of submerged assets, identifying potential vulnerabilities in hulls, dams, bridges, and offshore rigs before they escalate into critical failures.
Global Marine Heritage further extends its maritime role through salvage and wreck removal operations, helping to clear navigable channels and mitigate environmental hazards. The company’s scope encompasses a wide array of subsea engineering challenges, ranging from cathodic protection installation to preserve metal structures against corrosion, to detailed underwater surveys for environmental assessments. By integrating human diving expertise with robotic technology, Global Marine Heritage facilitates the continuous operation of maritime trade and energy production infrastructure throughout West Africa, ensuring that vessels and subsea installations remain safe, compliant, and structurally sound.
