Sleipnir Offshore Sdn. Bhd. offers a comprehensive package for the maintenance and repair of hydropower dams. This service is a specialized form of underwater civil engineering and construction, distinct from their more common offshore oil and gas work.
Their dam maintenance services are designed to address the unique challenges of subsea work within a freshwater environment. The complete package they offer includes:
- Civil Engineering: This involves the planning, design, and execution of structural repairs and modifications to the dam itself. This could include things like underwater concrete work or reinforcing existing structures.
- Survey: Before any work begins, a detailed survey is conducted to assess the dam’s condition, identify areas of damage or concern, and plan the scope of the project. This is crucial for precision and safety.
- Sediment Removal / Dredging: Dams and their intake areas often accumulate silt and debris. Sleipnir Offshore provides dredging services to remove this sediment, which can impede water flow, damage equipment, and reduce the dam’s efficiency.
- Stop/Log Installation: Stop logs are large beams or gates that are lowered into a dam’s sluiceway to block water flow, allowing for dewatering or repairs to be conducted in a dry environment. Sleipnir Offshore provides the expertise and equipment to install these safely and effectively.
- Plug Fabrication and Installation: Similar to stop logs, plugs are custom-fabricated components used to seal off a specific section of a dam for repair or inspection. Sleipnir Offshore handles the entire process, from fabricating the plug to its precise installation.
- Deep Diving (Saturation Diving): For tasks that require long duration or complex work at significant depths, the company employs saturation diving. This advanced diving technique allows divers to live in a pressurized environment for extended periods, enabling them to work for longer shifts at great depths without the need for lengthy decompression between dives. This is essential for deep-water dam maintenance and repair.
In essence, Sleipnir Offshore’s dam maintenance services combine their underwater engineering and diving expertise with specialized equipment to provide a complete solution for the inspection, repair, and upkeep of hydro-powered dams.
