Based in Riga, Latvia, ASPTR Ltd. functions as a specialized provider of commercial diving and underwater technical services for the maritime and offshore industries. Established in 1992, the company has operated for over three decades, building a specific profile around emergency response and complex subsea engineering. It serves a diverse client base that includes shipowners, port authorities, and maritime infrastructure operators within the Baltic region and beyond.
The company’s core operational focus lies in underwater technical works, where it employs certified divers and technical experts to maintain vessel integrity and efficiency. A primary component of its service portfolio involves the maintenance of commercial vessels, specifically hull cleaning and propeller polishing. These activities are critical for shipping operators seeking to reduce fuel consumption and maintain hydrodynamic efficiency. Furthermore, ASPTR Ltd. conducts underwater inspections in lieu of dry-docking (UWILD), allowing vessels to meet classification society requirements without the logistical disruption of dry-docking. These surveys utilize video and photographic documentation to assess the condition of hull plating, welding seams, and propulsion systems.
Beyond ship-specific services, the organization supports port and harbor infrastructure through hydrotechnical engineering. Teams perform comprehensive surveys of berths, piers, and other hydraulic structures to detect structural erosion or damage. The company is also equipped to handle the search and recovery of sunken objects, utilizing side-scan sonar technology to locate items on the seabed before initiating recovery operations.
A defining characteristic of ASPTR Ltd. is its operational philosophy centered on immediate deployment. The company maintains equipment and personnel in a state of constant readiness to address urgent maritime casualties or sudden repair needs. This "immediate start" capability is supported by duplicated mechanical systems and a fleet of specialized diving gear. The firm’s competence is acknowledged by major classification societies, ensuring that all underwater surveys and repairs adhere to rigorous international safety and quality standards. Additionally, the company preserves a connection to the history of its trade by maintaining a diving museum, reflecting its long-standing engagement with the evolution of underwater technology. Through these varied activities, ASPTR Ltd. acts as a key support entity for maritime safety and technical continuity in Northern Europe.
