DSV Saturation Diving Systems

Unique Hydra has an excellent track record in manufacturing classed commercial saturation diving systems.  As part of the Unique Maritime Group, and in co-operation with world-leading specialist sub-contractors, Unique Hydra is ideally positioned to continue manufacturing state of the art DSV saturation diving systems.  The Unique Hydra DSV diving systems typically include the following features:

  1. The system layout and chamber configuration will largely depend on the client requirements, the vessel layout and available spaces.
  2. The chamber system layout is designed such as to be ergonomically maximised as well as ensure the minimal noise and vibration transmission.
  3. Chamber complex design is to be integrated to the vessel design.
  4. Modular building blocks configurable to meet client and vessel requirements.
  5. Modular concept defines two compartment types, being a wet and a dry compartment with all supplies/controls arranged to service each type of compartment.
  6. Side mate or top mate bell configurations as this determines the bell trolley design.
  7. The bell handling system design – 2 wire/3 wire, hydraulic or electrical.
  8. Passive & active heave compensation systems.
  9. Chamber sizes from 2.3 to 2.4m in diameter.  Doors ranging from 700 to 900mm.
  10. Chamber dedicated sleeping and dedicated day areas with larger systems.
  11. Modern chamber fit-out with fully integrated work and entertainment systems.
  12. 6 to 8m3 bells.
  13. Twin bell or single bell.
  14. Considerations for fiber rope designs.
  15. Conventional two winch system or triple winch system.

Unique Hydra is actively developing Dive System Automation with much success.  Some salient features of how Unique Hydra will use this tried and proven technology to assist our clients include:

  • Primary focus is to support the operator in repetitive procedural tasks, system monitoring and logging.
  • Chamber monitoring includes – (Pressure, O2/CO2 content, Temp, RH, Fire Detection, Door positions, Gas supply pressure and analysis, SPHL status).
  • Chamber functions – (Pressure control, Oxygen make-up, Remote operation lights/scrubbers, Sewage system, Hydraulic door operation).
  • Diver/Dive Bell Monitoring – (Diver depth, Bell Depth, Hot water flow and temp, Breathing gas pressure and analysis, Bell power supply incl. batteries, onboard gas storage, dive logging).
  • Dive Machinery monitoring– (Compressor status, Hydraulic system status, Power supply status, Chamber and Diver reclaim status, ECU status monitoring, ambient O2 control).
  • Safety Critical Functions that could be automated include.
  • Monitor Oxygen Concentration
  • Monitor Carbon Dioxide Concentration
  • Monitor Pressure Gradient
  • Monitor Deco Rest Periods
  • Fire Alarms
  • Over Pressure Alarms
  • Manual Shut Down

Saturation Systems

HD Series Modular DSV System

Model No: 300 HDS 18 Twin Bell DSV

Description:
The HDS series of saturation systems is designed as the reliable solution to built-in DSV systems. Looking for a full enclosed saturation dive system with a twin bell system and two SPHL's, manufactured to the exacting requirements of the latest DNV regulations, then this is the one for you! The HDS systems are easily integrated on purpose- built medium to large DSV's for continuous saturation work-scopes. The HDS 18 DNV / IMCA system is designed for launching two bells through independent moon-pools utilising a gantry system. The SPHL's are deployed directly over the side of the vessel making it an easily integrated system. The chamber system consists of five separate chambers, all twin lock configurations. There are four separate living areas, two are capable of sleeping 6 persons and two are capable of sleeping 3 persons. The come-out chambers are fitted with a dedicated medical bunk and independent sanitary facility lock. The SPHL's are fitted out as dedicated 18-person SPHL's. The dive and sat control rooms are fitted into their own dedicated ship spaces with conveniently positioned windows. All of the machinery for the system is fitted in and around the diving system. The hydraulic systems are our proven DNV approved / IMCA compliant, 15 ton and 7.5 ton winch combinations with a dual redundant power- pack. Our saturation dive systems come complete with a full IMCA Audit package, asset list and PMS software package. The system is also extensively tested through use of the latest FMEA methodologies in our yard before being shipped, thereby ensuring first- time operation during mobilisations and low commercial risk on your project.

Saturation Systems

HD Series Modular DSV System

Description:

The HDS series of saturation systems is designed as the reliable solution to built-in DSV systems. Looking for a full enclosed saturation dive system with a single bell and two SPHL's, manufactured to the exacting requirements of the latest DNV regulations, then this is the one for you! The HDS systems are easily integrated on purposebuilt medium to large DSV's for continuous saturation work-scopes. The HDS 15 DNV / IMCA system is designed for launching the bell through a moon-pool utilising a gantry system. The SPHL's are deployed directly over the side of the vessel making it an easily integrated system. The chamber system consists of a triple-lock 6-man chamber with the living area fitted out for 6 people, and two twin-lock chambers with a 6-person habitat facility and a 3-person come-out facility with independent wet-pot facility. The SPHL's are also fitted out as dedicated 16-person SPHL's. The dive and sat control rooms are fitted into their own dedicated ship spaces with conveniently positioned windows. All of the machinery for the system is fitted in and around the diving system. The hydraulic systems are our proven DNV approved / IMCA compliant, 15 ton and 7.5 ton winch combinations with a dual redundant powerpack. Our saturation dive systems come complete with a full IMCA Audit package, asset list and PMS software package.

Saturation Systems

HD Series Modular DSV System

Model No: HD-SE 12 DNV

Description:

The HD series of saturation systems are designed as the modular DSV add on system. Looking for a full enclosed saturation dive system, yet do not want to buy another vessel. This is the answer! The HD systems are easily deployed on medium to large DSV's for occasional saturation work-scopes. The HD-SE 12 DNV/IMCA system is designed for launching the bell through a moon-pool utilising a gantry system. The SPHL is deployed directly over the side of the vessel making it an easily integrated system.
