Synopsis

Using the latest Siemens 8000H gas turbine technology, this new 550MW combined cycle gas turbine (CCGT) unit has joined the eight existing gas turbines at the Black Point Power Station (BPPS) to boost local gas power generation to around 50% of the total fuel mix. This is part of CLP’s commitment to help Hong Kong meet its pledged environmental targets for 2020. Arup has acted as the Owner’s Engineer for CLP on this once-in-20-years project, offering architectural, landscape, civil, structural, geotechnical and building sustainability design services.

The key component of this project is the once-through cooling water (CW) system. The planning and design solutions have to suit the brownfield site where the works are heavily constrained by existing structures and geometries. The two key constraints in this case are the location of the intake and outfall defining the routing, and the array of eight CW pipes supplying the eight CCGT units in operation for the production of a total of 2,500MW which defines the methodology.

The construction itself is also challenging. For example, the seawater intake construction involved substantial modification of the existing intake culverts to form a branch connection to the new pumping station. This work is conducted wholly within an underwater excavation and lateral support scheme and the permanent work is made up of precast concrete units. Another challenge is the construction of the CW system that uses steel reinforced cylinder pressure pipes with an internal diameter of 2.6m. To avoid the deep rock fill layers formed during reclamation works in the early 1990s, a total of three launch/retrieval shafts with depths of 25-35m were constructed for two tunnel boring machines working at the same time. This includes approximately 400m long curved pipe jacking works, setting local records in terms of size and curved alignment.

In this talk, representatives from the Owner, CLP, and the Owner’s Engineer, Arup, will share how they have overcome these challenges in this fast-track project.
