Sleipnir Offshore offers specialized services related to hyperbaric and wet welding, which are critical techniques for underwater construction, maintenance, and repair. This capability is supported by a dedicated hyperbaric testing system that allows them to ensure the quality and safety of their underwater welding procedures and personnel.
Here’s a breakdown of their service and what it entails:
- Wet Welding: This is the most common form of underwater welding, where the welding process is performed directly in the water. While it is efficient for many tasks, the quality of the weld can be affected by the surrounding water, which cools the weld rapidly.
- Hyperbaric Welding: This is a more advanced technique where a dry, pressurized environment is created around the weld site using a habitat or a cofferdam. This “dry” welding in a hyperbaric (high-pressure) environment results in a higher quality weld, comparable to those done on the surface. It is used for critical structural repairs where weld quality is paramount.
- Hyperbaric Testing System: Sleipnir Offshore operates a purpose-built hyperbaric system that is central to their welding service. This system is a controlled environment that can simulate the pressure and conditions at various depths. Its key specifications are:
- Lloyds Certified: This certification is a globally recognized standard for quality and safety, ensuring that the system and the procedures carried out within it meet rigorous international benchmarks.
- 8-Man Saturation System: This indicates that the system is large enough to support a team of up to eight divers in a saturation-diving scenario, where they can live and work under pressure for extended periods.
- 200-meter Depth Rated: The system can replicate the pressure experienced at depths of up to 200 meters, allowing for accurate testing of welding procedures for deep-water projects.
- Work Chamber (48” Pipe): The system has a dedicated work chamber that is large enough to accommodate a 48-inch pipe, making it suitable for testing welding on large-diameter pipelines and other structures.
- Life Support Units: The system is equipped with all the necessary life support units to sustain the divers safely throughout the testing and training process.
In summary, Sleipnir Offshore uses its advanced hyperbaric testing system to provide a full-service solution for underwater welding. This allows them to certify their welders and welding procedures to the highest standards, ensuring that they can perform critical wet and hyperbaric welding tasks with exceptional quality and reliability.
