The comprehensive onboard safety measures, including medical facilities and decompression chambers, significantly mitigate operational risks, prioritizing the safety of all personnel. This aspect renders DSVs not just a practical option for intricate underwater projects but also a safer alternative. Additionally, the ability of DSVs to facilitate operations using remotely operated vehicles (ROVs) broadens the range of tasks they can undertake, rendering them indispensable across various sectors such as oil and gas, marine infrastructure, and scientific exploration.

Chartering a DSV provides access to these specialized assets without the hefty investment in ownership and maintenance, offering a cost-effective solution tailored to specific project requirements.

Types of DSVs available for charter

The spectrum of Diving Support Vessels (DSVs) available for charter is designed to accommodate the diverse requirements of marine projects, offering specialized capabilities for a range of underwater operations. The main categories include Saturation DSVs and Air Dive DSVs. Saturation DSVs are tailored for deepwater and extended duration dives, featuring advanced systems that enable divers to work at significant depths for prolonged periods.

These vessels have been pivotal in operations such as the North Sea oil field maintenance, where their ability to support divers for long durations at great depths is unmatched. Conversely, Air Dive DSVs are optimized for shallower, shorter duration dives. They are frequently employed in projects like the inspection and repair of underwater pipelines in the Gulf of Mexico, where their agility and rapid deployment capabilities are highly valued.

Each type of DSV boasts specific features like dynamic positioning systems, advanced dive system capabilities, and comprehensive onboard safety measures. These attributes ensure the vessels’ ability to conduct a wide array of underwater tasks efficiently and safely, rendering them invaluable for projects in the oil and gas sector, underwater infrastructure development, and marine research.

Saturation DSVs

Saturation DSVs are specifically designed for deepwater and extended duration dives. These vessels are equipped with complex saturation diving systems, enabling divers to undertake missions at depths exceeding 100 meters for prolonged periods. An example of their use includes the installation of subsea wellheads and the laying of pipelines in deepwater projects off the coast of Brazil, where their advanced capabilities provide the necessary support for divers under extreme conditions.

Saturation DSVs offer the advanced capability needed for challenging deep-sea endeavors, providing a safe and controlled environment for divers during extensive operations.

Air Dive DSVs

Air Dive DSVs are tailored for shallower, shorter duration dives, equipped with air diving systems that are optimal for operations up to approximately 50 meters in depth. These vessels have been effectively used in the recovery of objects from the seabed and in the inspection of ship hulls in the Mediterranean Sea, showcasing their versatility and efficiency in less demanding diving conditions. Air Dive DSVs present a practical and efficient solution for projects that do not necessitate the extensive capabilities provided by saturation diving, making them a preferred choice for a wide array of marine and underwater construction tasks.

Key features to look for in a DSV for charter

When selecting a Diving Support Vessel (DSV) for charter, certain key features are essential to ensure the vessel meets the demands of your underwater operations. Dynamic Positioning Systems are critical, as they allow the vessel to maintain a precise position over the dive site, crucial for the accuracy and safety of the operations. For instance, the use of advanced dynamic positioning systems, such as those developed by Kongsberg and Wärtsilä, has been pivotal in the successful completion of complex underwater installations and repairs, where precision is paramount.

The vessel’s Dive System Capabilities are equally vital; this includes having advanced saturation dive systems for deepwater operations, air dive systems for shallower tasks, and the capability to deploy Remotely Operated Vehicles (ROVs) for inaccessible areas. Technological advancements in dive systems, like those from companies such as Subsea 7 and TechnipFMC, have significantly expanded the range of feasible underwater projects, enabling safer and more efficient operations at greater depths. Onboard Safety Measures are of paramount importance, including comprehensive medical facilities, decompression chambers, and established emergency protocols to protect the health and safety of the crew and divers.

The integration of advanced medical and safety equipment, alongside rigorous safety protocols, has been instrumental in minimizing risks during diving operations. For example, the inclusion of hyperbaric rescue facilities and the adoption of stringent safety standards, akin to those set by DNV GL, underscore the industry’s commitment to ensuring the utmost safety of all personnel involved.
