Songa Offshore has informed that the scope of work for the Songa Dee Special Periodic Survey (SPS) has progressed according to plan, including the budget of 60 days and USD 90 million.
The rig has during the yard stay achieved its certification on hull and structure by DNV, the BOP has been overhauled and lifted back on-board. The commissioning of the BOP, as well as the winch upgrades, are in its final stages.
During the yard stay the Songa Dee has, however, experienced unexpected failure on one of the four main engines. Critical parts for the engine are currently being prepared for re-installation. The rig is expected to leave Invergordon, Scotland, on 7 November 2014, allowing it to be back on day rate a few days later. The costs related to the engine incident will be claimed against the insurance and are not expected to impact the overall yard stay costs beyond the budget.
Songa Dee is an 112 by 80 meters wide Norwegian operated semi-submersible rig. The rig was moored at the Invergordon facilities deep water quay Queens Dock in September 2014 for a Special Periodic Survey work.
