TOWHEAD MANIFOLD

The overhead shows a model of a typical integrated towhead manifold that can be towed and installed in the field with the bundles. The pipework and valving for each well within the manifold is a series of repeated modules for water injection or production. The towhead manifold can incorporate pigging loops and electric hydraulic control systems for the manifold valves and associated trees. A typical structure will be 30 m (98 ft) long, 4 m (13 ft), wide and 3 m (10 ft) high with a weight in the region of 100 tonnes (110 US tons). It can be designed either as a gravity-based structure or (as shown above) piled in position. Overhead protection can be provided by hinged grillages or separate protection structures as required. As mentioned previously the towhead on the Jura Project installed in 2007 weighed approximately 500 tonnes.
