Heerema's Deepwater Construction Vessel, The Thialf

Description

Overview

Thialf is a deepwater construction vessel (DCV) owned and operated by Heerema Marine Contractors, flying a Panamanian flag.

She is also often referred to as a crane vessel, of which she currently holds the record as the world's largest, having a lift capacity across her two cranes (tandem lift) of 14,200 t (15,600 short tons).

Thialf was constructed by Mitsui Engineering & Shipbuilding Co., Ltd. Japan and delivered to McDermott in 1985.  McDermott and Heerema joined forces to form HeereMac, but this joint venture ended, with Heerema taking on the Thialf.

Notable offshore work includes:

  • Shell's North Sea Brent Spar decommissioning (1998)
  • Shell's North Sea Shearwater topsides installation (2000)- a world record of 11,883 t
  • BP's Gulf of Mexico Holstein topside installation-world's largest spar (2004) - a Gulf of Mexico record: 7,810 t.
  • Chevron's Belize Benguela compliant tower foundation pile installation (2005) 

The name Thialf, comes from Thjálfi, the name of a servant to the Norse mythological god Thor.

 

Design & Capabilities 

Thialf is a semi-submersible by design, with a displacement of 198,750 t.  The hull is constructed of two pontoons with four columns on each.

She is equipped with class III dynamic positioning systems

Although Thialf can take on multiple roles within offshore construction including, including diving and act as an accommodation barge, her primary role is as a heavy lift vessel.  For this Thialf is equipped with two cranes that in a tandem lift, have the capacity to lift 14,200 t (15,600 short tons) to a height of 31.2 meters, making her the largest crane vessel in the world.

Thialf has an accommodate capacity of 736.
