The winches destined for Pier IV at Vale do Rio Doce, are ready to be loaded in the port of Vigo. Vale do Rio Doce, which is in the process of renewing equipment at its loading terminal on Pier IV South, has chosen Ibercisa Deck Machinery to supply its winches for this new project which will allow the mining company to considerably increase its business thanks to improvements in security and reliability when docking the Valemax vessels. The equipment of this order is identical to the first order supplied by Ibercisa for the company's terminal in Sao Luis do maranhao, the optimum performance of which has led to this second contract.
A total of 26 hydraulically driven winches, each with its own hydraulic unit and control panel for operation either by remote control from a central command post, or locally, in situations where communication is lost. This order includes local remote control which allows the operator to control the machine with improved tracking of mooring manoeuvres.
The machines have a split drum with a total side capacity of 170 metres (150m of mooring rope plus 20m of wire) and the other side of the drum is reserved for working on the first layer. The Ibercisa system achieves speeds of up to 25m per minute at high speed and 4m a minute at slow speed with a full load. The braking capacity of the machines is 150 tons, proven by trials for the previous order at the Vigo factory, achieving up to over 180 tons.
The mooring system destined for South Pier IV includes a few modifications to the previous contract. Some changes have been made to the HPU and on the hydraulic unit to improve operation, and on the fairleads to give a better operating angle and improve working capacities.
The fairleads are designed by Ibercisa to the specific requirements of Vale. This model consisting of four rollers is able to support outflow angles of over 90º with tension levels of over 180 tons, and has sufficient room to allow for circulation of mooring links of 80 tons of SWL.
