The project includes the design, procurement, construction, testing and commissioning of a seawater cooling pipeline network.
The main items of work comprise:
Supply and return seawater cooling pipelines to and from Yanbu Industrial City II together with a spare supply / return pipeline. These pipelines (3 nos.) will each be approximate 5 Km in length and of equal diameter and to be laid in a common trench and will run in the Royal Commission Corridor. The mechanical works consist of valves including isolation (butterfly) valves, air valves and pressure reducing valves.
Actuators for operation of butterfly valves greater than 600mm diameter together with local cabinet for electrical isolation and connection point for a mobile electrical generator.
Earthing for valves / actuators.
Cathodic protection will be provided for underground and submerged metallic structures.
