Cranes

Description

BHC is seeking to enter into a framework agreement with a service provider for the provision of: (a) one or more new rail mounted four wire grab crane(s), to be used in the unloading of grains, animal feedstuffs and other dry bulk materials from ocean going vessels into a rail mounted hopper, controlled by an operator in the operator cabin; together with (b) parts/spares packages and training; and (c) options for the supply of support and servicing. The value below therefore represents the best estimated total value, taking into account the total number of cranes which may ultimately be purchased and all of the options described. BHC is seeking to enter into a framework agreement with a service provider for the provision of: (a) one or more new rail mounted four wire grab crane(s), to be used in the unloading of grains, animal feedstuffs and other dry bulk materials from ocean going vessels into a rail mounted hopper, controlled by an operator in the operator cabin; together with (b) parts/spares packages and training; and (c) options for the supply of support and servicing. The estimated value therefore represents the best estimated total value, taking into account the total number of cranes which may ultimately be purchased and all of the options described. The crane must derive its electrical energy from a connection point on the quay. BHC is currently reviewing its options in this regard, and it is anticipated that bidders shortlisted following the PQQ stage of this procurement process will be asked to submit tenders providing options for both a high and low voltage connection. Further information will be provided within the Invitation to Negotiate. The crane must be designed to meet the following minimum requirements: • the crane must be capable of discharge rates of a minimum 600 tonnes per hour based on feedstuffs with a bulk density of 600 kg/m3. BHC's preference is also for a discharge rate of 850 tonnes per hour based on grains with a bulk density of 750 kg/m3. The crane will have an outreach from the axis of rotation of the crane to the centre of the grab of 10 m to 30 m and will have a lifting capacity of approximately 25 tonnes including the weight of the grab. • the crane rails have a span of 5 486 mm and an allowable maximum load of 24 tonnes/running meter. • design standards according to the standards specified in the Pre-Qualification Questionnaire. • design lifetime: 25 years (with an expected number of cycles being 2 000 000). The crane will need to be designed to meet this lifetime/expected number of cycles, however BHC cannot specify the exact number of cycles that will be required. Three heavy duty four rope attachments are to be supplied with the crane. It is currently anticipated that these will comprise one hook with a rated capacity of 25 t and two clam shell grabs with a capacity to achieve the preferred discharge rate of 850 tph for products with a bulk density up to 750 kg/m3 for grain products. BHC may, but gives no commitment that it shall, also purchase support and/or servicing from the successful bidder. BHC is seeking the shortest overall delivery programme (subject to BHC being reasonably satisfied that the delivery programme is achievable) and for operational reasons, BHC's preference is a maximum lead time for delivery and commissioning of the crane of 18 months from order confirmation by BHC. Both within and outside the warranty period for the crane, anticipated to be a minimum of two (2) years from handover, BHC must be able to call upon the successful bidder to attend the harbour to provide on-site technical assistance within the next working day following such a request. Bidders should note that, in relation to the duration of any order placed under the framework agreement, it is anticipated that there will be an option for BHC to place an order for a maintenance and servicing contract (including the purchase of parts or spare parts) with the successful bidder (for up to a maximum of 25 years), but this is an option only at this stage. At the Invitation to Negotiate stage of this process, qualified bidders will be provided with BHC’s specific functionality requirements for the crane, in relation to which bidders will be asked to provide their proven design and demonstrate how the crane will operate including (if requested by BHC) by way of a site visit at the bidders’ cost.
