Description
SRK Consulting (Russia) Ltd commissioned CGR to prepare an outline cost estimate for a ship loading facility on the island of Novaya Zemlya off the north coast of Russia. The facility is required for loading 8,000 to 10,000 tonne vessels with fine and loose mined lead an zinc concentrates from a covered, heated stockpile facility.
The proposed facility is located on the western coast of Novaya Zemlya in the Fjord of Bezymyanaya Bay and is planned to handle approximately 200,000 tonnes of zinc concentrate and 45,000 tonnes of lead concentrate per annum. In addition the facility will also need to handle and store 20,000 tonnes of fuel and up to 25,000 tonnes of reagents, bulk bags and other consumables per year.
The region is located within the arctic zone requiring the outline design and cost estimate to account for permafrost conditions as well as thick sea ice (up to 650mm) for up to 5 months of the year, severely limiting access to the facility. The location is dominated by rocky ground with overlaying rubble of up to 3m thickness, with surrounding area consisting of low hills with narrow, steep river valleys between.
The port facility proposed by CGR consists of a 160m long suspended deck structure capable of berthing up to 10,000 DWT vessels. An access bridge supported on piles connects the wharf to the shore. A minimum berth pocket of 7m depth was provided for berthing of a single vessel with sufficient space for unloading of consumables and conveyor system for the handling of the bulk concentrates.
A heated storage facility was included with a capacity of approximately 31,700m3 of bulk material. Three further building where also included: one for storage of consumables, another for storage of port operating plant and an additional small building for use as a port control office.
A yard area was also incorporated, with sufficient space to store 40ft containers. Plans also included a refuelling area, comprising of a fuel storage tank with 20,000 tonne capacity, connected to a delivery pipe leading to the wharf to allow filing from a liquid supply vessel.
