The Castoro 7 was a work ship that sailed under the flag of Panama and was used as a seagoing pipeline ship. The ship, built in 1975 in the Dutch shipyard IHC Gusto Schiedam under the name Viking Piper , was last owned by the Portuguese subsidiary of the largest Italian offshore service provider Saipem , a former subsidiary of the energy company Eni . The ship was scrapped in Alang (India) in June 2016 .

The ship changed hands several times over the years and with it the name. The ship was also known as the McDermott Lay Barge 200 . J. Ray McDermott resold the ship to Acergy . In 2009 the sale of the ship, which last operated under the name Acergy Piper , to Saipem was completed.

Structure and technology

Hull and drive

The Castoro 7 was designed as a semi-submersible ship , like many large work ships in the offshore industry, to vary its draft by controlled flooding of ballast tanks. The draft of the overpass was around 11.5 m. During work, the draft was increased to up to 20 m in order to increase stability .

A diesel-electric drive was used to move and position the Castoro 7 . The power generation was done by eight diesel engines from Wärtsilä (type: 9L20C3 ).

14 anchor winches attached to 3000 m long steel cables with a diameter of 76 mm (3 inches) were used for anchoring . Eight 22.5 t, five 20 t and two 15 t anchors were used.

Pipeline laying and other equipment

The pipelines were laid using the S-Lay method and were possible up to a diameter of approx. 1.5 m (60 inches). The five tensioners from Western Gear achieved a pulling force of 340 t. 2000 t of pipelines could be transported on the deck. The laying rate was up to five kilometers per day.

Accommodation and helicopter deck

The living module offered space for 401 people. The accommodation complied with international safety standards and, in addition to the cabins, offered relaxation areas, offices, an infirmary, a cafeteria, a cinema and a fitness center. The helicopter deck was approved for helicopters up to the size of the Sikorsky S-61 .

Projects
