Jumbo Offshore’s core business is the transportation and installation of subsea structures and mooring systems in water depths up to 3,000m. Structures we transport and install include:

  • Templates and manifolds
  • Mooring systems for FPSOs and offloading buoys (including driven and suction piles)
  • Smaller jackets and topsides (installation and removal)
  • Transition pieces and foundations (e.g. tripods, jackets and monopiles) for offshore wind turbines

Heavy-lift offshore vessels

Jumbo has access to 12 heavy-lift vessels. Two vessels have DP2 and are used for a wide range of subsea installation work: Jumbo Javelin and Fairplayer. Both ships have a 17kn transit speed, a flat working deck of 100m × 26m and a large, adjustable cargo hold. Two 900t mast cranes are mounted on the starboard side. For transportation services these cranes can lift 1,800t in tandem operation; offshore they can handle up to 1,100t.

Deepwater-structure lifting and installation system

With its patented deepwater deployment system (DDS) Jumbo can lift large and heavy structures from deck and place them on the seabed without the need for subsea transfer. Typical weights and depth ranges are:

  • 1,000t in 1,000m
  • 600t in 1,700m
  • 200t in 3,000m

QHSE for heavy-lift offshore vessels

Working safely is always at the forefront of Jumbo’s methods and mentality. We approach QHSE with total dedication. Our Stay Well programme aims at safety awareness and incident prevention. Both ship crews and office staff follow courses at regular intervals, with the crews also training with Jumbo’s in-house dual crane simulator.
