Statoil commits newbuild semis to Troll

Statoil has contracted Songa Offshore to build two new semisubmersibles for drilling operations offshore Norway. The $2.47-billion contract for the two category D rigs covers a fixed eight-year charter period. However, the value could increase following commencement of the drilling program due to escalation provisions taking effect from 2011.

The category D rig is designed to operate in 100-500 m (328-1,640 ft) of water and to drill wells to 8,500 m (27,887 ft). It will serve as a workhorse on Statoil’s mature fields, mainly drilling and completing production wells, allowing Statoil to produce more oil from the fields.

Various topside suppliers, yard, and rig owners helped develop the concept. DSME in South Korea will build the rigs, with Aker Solutions supplying the drilling equipment.

Mobilization to the North Sea will take around three months. The rig hand-overs are scheduled for 1Q and 3Q 2014. First field to be serviced by the new rigs will be Troll in the North Sea, which last year produced on average over 120,000 b/d of oil.

Although both rigs are under eight-year contracts, these are extendable with four three-year options, which could lead to a 20-year contract for each rig. Statoil says this long-term approach should ensure rig capacity for its growth needs, as well as providing predictability for the rig contractor.

Statoil is also considering adding two further category D rigs via an option with Songa Offshore, although it continued to evaluate offers from other bidders. Later this year Statoil will consider contractual options for construction of the extra semis, which could include taking an ownership position.

Jumbo expands heavy-lift fleet

Jumbo Shipping has commissioned the Brodosplit shipyard in Split, Croatia, to construct a new heavy-lift vessel. This will be 152.6 m (500 ft) long with a beam of 27.40 m (90 ft), and will be equipped with two 1,100-metric ton (1,212-ton) cranes providing 27.5 m (90.2 ft) outreach. In tandem the cranes will be able to lift up to 2,200 mt (2,425 t).

For offshore operations, the vessel will be prepared for DP-2 installations, and it will be built to ice class to allow it to work in Arctic regions. Jumbo expects to take delivery in March 2013, with the vessel being operational three months later. It has an option to build a second vessel at the Brodosplit yard. The investment will expand Jumbo’s fleet of heavy lift vessels to 13, with lifting capacity in the range of 500-2,200 tons.
