Dof Subsea has signed new frame agreements for work in the North Sea, which the company said will secure utilisation of around 100 vessel days.

The pacts have a combined value of around NOK 80m ($9.1m) and comprise inspection, repair and maintenance (IRM) and survey work.

"The award of these contracts and frame agreements highlights Dof Subsea's versatility and ability to respond to differing client requirements using the extensive experience and competence within our resource pool," said Jan-Kristian Haukeland, executive vice-president of Dof Subsea Atlantic.

Separately, three Dof vessels have won contracts for work in the North Sea over the next few months.

Unnamed clients in the UK and Norway have chartered Dof's 35,024-bhp anchor handler Skandi Skansen (built 2011) and two platform supply vessels: the 4,900-dwt Skandi Hera (built 2009) and the 3,600-dwt Geosund (built 2001).

TradeWinds has learned that Skandi Skansen is employed by ConocoPhillips and Skandi Hera for Spirit Energy.

AIS tracking data shows Skandi Skansen is en route to the North Valiant gas field in the UK North Sea, which is operated by ConocoPhillips.

Skandi Hera's latest AIS update shows the ship is bound for the UK's Ensign offshore gas field, which is operated by Centrica.

Geosund, meanwhile, has been active during the past two weeks at Norway's Balder Field, which is owned by Var Energi, of which Eni Norge is majority shareholder.

Dof did not disclose the vessels' contract rates or duration.
