‘Etesco Millennium’ at Gibdock

Gibdock says that it has completed work on its first offshore platform project in almost 15 years, as well as its first PCTC job for a long time.

The semi-submersible accommodation platform Etesco Millennium was at the yard for an eight-month stay, arriving in October 2011. The yard worked closely with owner Nazca Floatel and shipmanager Okeanos, both of the Netherlands, in carrying out an initial inspection and then more detailed surveys. Subsequently, ultra high pressure work was carried out by subs supplied by the owner, with the yard providing 11,000m3 of staging. This part of the job incorporated extensive blasting and cleaning, including work in the submerged tank areas, and necessary steel repair works to the cross braces on the columns of the rig.

Gibdock says it is targeting offshore rig repairs as a significant new area of business and believes it can capitalise on its geographic location to win more orders in this sector. The technical side of the job brought out the best in the yard, according to John Taylor, Gibdock production director: “It was quite a complicated repair job to get the rig into the condition required by the owner. Our steelwork and welding skills were the key to getting this right to the satisfaction of ABS, as the classification society involved, as well as Okeanos.”

The 22,604gt modified semi-submersible rig, Etesco Millennium is now being marketed for a new offshore deployment. Originally built by Marathon LeTourneau in 1976, the rig is 88m long and 66m wide at its maximum point and is consequently one of the biggest structures ever handled by Gibdock.

Other recent projects at Gibdock include extensive repairs to the German-owned containership Westerburg and the Norwegian offshore accommodation vessel Edda Fides. Jubilee Hope, a former Royal Navy tender is being converted into a floating medical centre to serve on Lake Victoria in Tanzania. Vehicle carrier CSAV Rio Aysen, which docked at Gibdock in June, became the first of its type to be handled at the yard for many years. Managed by UK-based Zodiac Maritime, the 46,800gt PCTC was built in 2007 and visited for routine repair and maintenance including a significant amount of steel work. Chemical tanker Dubai Star visited Gibdock in July for general repairs and drydocking work, while PSV Hugin Explorer, on charter to Fugro Offshore, visited for minor repairs and repainting. The 75t BP tug Tron docked in July for work on its Voith Schneider propulsors. Having liaised with owner Boluda and Voith Schneider, Gibdock undertook modifications to the struts that hold the base plate in place. The old struts were cut off and replaced with new struts in a different arrangement. The work was carried out during a 15-day docking at the yard, during which other minor repairs were carried out.
