Sullom Voe Terminal – Manufacture Pipeline Pig Cradle
Client: Sullom Voe Terminal
Location: Sullom Voe, Shetland


Changes in the equipment used for pipeline pigging created the requirement for a new, larger cradle to receive the pigging tools at Sullom Voe Terminal. The pig cradle sits upon a trolley, which runs on a short length of rail and can readily access the pig receiver. The assembly can be safely moved out of the way for cleaning and preparation of the pig for onward transportation.

Ocean Kinetics was requested to develop a new transportation cradle to suit a 22″ diameter tool of up to 6.25m length. A trolley was also to be developed which could hold either the existing transportation cradle or the new one. The assembly was to be designed to take a 5-tonne safe working load.


Ocean Kinetics developed a number of 3D models in Solidworks to present to the client. This methodology offered the benefit of being able to discuss options at an early stage and allowing the end users to have input into the best mode of operation, interaction with the existing facilities and also any hazards that could arise (such as pinch points).

Once a preferred solution was selected, this was fully developed in Solidworks. Stress analysis for lifting was undertaken as a combination of finite element analysis and hand calculation.

Traditional 2D fabrication drawings were generated from the 3D model. As full joint level traceability was requested by the client, this was incorporated at the drawing stage.

Manufacture was then undertaken by Ocean Kinetics with coded, full quality assurance, inspection & testing (including load testing), painting and delivery.

The client was happy with the end product and made recommendations to others within their organisation.
