Plan change for salvage
Last week the Albatros Offshore Substation, weighing 1,200t, arrived in the heart of Rotterdam’s dock land by barge from Heerema Fabrication Group’s yard in Zwijndrecht. The self-propelled DP2 crane vessel Gulliver, owned by Antwerp based Scaldis, lifted the topside off the barge and transported it, suspended, across the Nieuwe Maas river to the Heysehaven where the Pacific Osprey was ready with sea-fastenings fitted on the after deck of the Heavy Lift Jack-up Vessel.
The Pacific Osprey sailed from Rotterdam on Wednesday midday bound for the EnBW Albatros Offshore Wind Farm in the German Bight where the DEME Offshore Vessel, Innovation, would also be arriving from Eemshaven. The wind farm is located next to the EnBW Hohe See Wind Farm, located 95 kilometres north of Borkum and 100 kilometres northwest of Helgoland.
Both the Innovation and the Pacific Osprey jacked up close to each other and the monotower substructure on to which the substation topside would be installed. The lift from the Pacific Osprey on to the monopile was made by the Innovation’s crane in the early morning yesterday, Wednesday 27 March. The Pacific Osprey will remain on location after the lift off to assist with outstanding coating and welding work. The Seafox 2 is due to continue thereafter with further commissioning work.
The Innovation has a Liebherr CAP 64000 – 1500 Litronic crated with a maximum lift of 1,500t at 31.5m. The Pacific Osprey is waiting to be installed with a new jib, after the jib tip fracture last year.

Plan change for salvage
TWD has designed a hammock to support monopiles during transport. This innovative seafastening is suitable for monopiles with a diameter between 7 and 11 metres. In addition, it divides the forces on the tube more evenly. This allows contractors to safely transport various wind turbine monopiles with a thinner and therefore more vulnerable wall thickness. An interview with Thijs Roethof of TWD.
Gulliver and Rambiz left their safe haven, Hanoytangen, at 07.00 and 09.17 this morning, Sunday 24 February, respectivly
