THOR Systems

(Thrust Hyperbaric Offshore Recovery) Systems

THOR Systems are used for the recovery of HRC's (Hyperbaric Rescue Chambers) and SPHLs (Self Propelled Hyperbaric Lifeboats).  
​
THOR Systems have been designed to suit a wide variety of vessels allowing rapid installation.  Typically they are fitted to Anchor handlers (AHTS), or Platform Supply Vessels (PSVs), although they can also be fitted to smaller lighter vessels.
​
Thrust Maritime have two THOR Systems available for rent; they are identical and have a 50t SWL (design load of 81t, which allows for a 25t SWL capacity when carrying people). They are fully certified to DNV 2.22 Lifting Appliances for use in the Offshore environment, with specific man-riding / personnel lift and subsea lift certifications.
​
Our THOR systems are:
  • Available globally for project based rental;
  • Specifically designed for HRC, SPHL and lifeboat recovery;
  • Provided with a Patented Winshackle System for handsfree SPHL / HRC / lifeboat Hook up;
  • Designed to control swing in accordance with IMO LSA impact requirements;
  • Easily mobilised on 2 x 40 ft flat rack containers;
  • DNV certified with design capacity of 81t; allowing high sea state recovery;
  • Certified for Man-riding / Personnel lifting;
  • Suitable for a broad range of vessels; and
  • Suitable for a broad range of marine lifting operations.
​
Provided with full vessel integration, including:
  • Support in vessel selection;
  • Classification Society Approval;
  • Stability, motion, structural and metocean analysis;
  • Experienced, dedicated installation team with specialist tooling; and
  • Rapid installation and removal.
​
Differentiators:
  • Designed for SPHL recovery;
  • Field proven in harsh Bass Strait conditions;
  • Fitted with our Patented Winshackle;
  • Economical project based rental;
  • Focused, agile and responsive team;
  • Equipment certified by DNV (or equivalent at client request); and
  • ISO 9001, 14001, 45001 and AS/NZS 4801 certified by Bureau Veritas.
 
Past performance:
  • Commenced in 2011, with in excess of 30 installations /operations completed;
  • End clients have included: Total, Woodside, Chevron, Santos, Quadrant and Origin Energy.
Optimally THOR systems are configured for over the side recovery. Over the side recovery provides the following significant benefits:
  • Allows both SPHL and HRV to head into weather during recovery;
  • Locating THOR at midships reduces motions; and
  • Allows steering of SPHL as water passes over rudder.
The THOR System modular design allows efficient mobilization on a B-double truck or 40ft flat rack containers.
 
The slideshow to the left details typical installation steps.  Installation typically takes 1.5 to 3 days depending on a variety of factors.
 
We have a specialist team to engineer the interface to the host vessel.  Normal connection detail is either through down bolting or side bolting with welded bolt plates.  As part of this process we conduct structural, motion and stability analysis for the host vessel.  We then generate installation drawings, procedures and a supporting integration design report.
