Mobile cranes are widely used in the engineering industry for the construction and assembly of heavy machinery, infrastructure and other large payloads. ASPEC has developed modelling and calculation tools to easily assess the suitability of cranes early in the design process.
Bridges and culverts are important assets in road systems. They allow safe travel of vehicles over obstacles and cater for effective water flow of rivers and drains. Understanding the requirements and the need to undertake inspections is vital in maintaining the key assets.
Aspec Engineering has conducted several loading chute projects for Port Waratah’s Shiploader 07.08 to help improve its performance, reduce down-time and to help comply with environmental guidelines.
March 2021 marked the 10th anniversary of ASPEC’s Perth office. This article outlines some of the key projects and personal contributions over that time that enabled us to deliver quality services for our clients and enjoy our work.
Conveyor noise is generated by bulk material impacts, drives, vibrating structures, ancillary equipment and conveyor idlers. Previously, idler noise was evaluated with self-noise experiments. More recently, idler noise experiments have changed to measure operating-noise which is created by the interaction of the conveyor belt and the idler.
Inspection of industrial structures utilises a condition rating system to track the degradation level of steel and concrete over time, using a 1 to 5 scale rating (pristine to unserviceable). The system allows for a consistent rating from any inspecting engineers. The paper gives background on the condition rating from the inspection system developed by ASPEC’s engineers.
This article describes design considerations for offshore marine bulk loading terminals. A form of construction using prefabricated steel jackets like those used in the offshore industry for drilling platforms is looked at in detail including design and construction requirements for application to large offshore dry bulk materials handling berths.
At many existing bulk material handling facilities, equipment such as stackers, reclaimers and ore car dumpers are nearing the end of their design lives. Owners are faced with the decision on whether to refurbish existing or procure replacement machines. ASPEC’s program called FULS (Fatigue Useful Life Simulation) helps determine when to carry out machine replacement or major refurbishment.
ASPEC is extremely proud to see the ongoing success of the Surf Lakes Full Scale Prototype, located in Yeppoon, Queensland, which has now been shortlisted as a finalist for the 2020 Australian Engineering Excellence Awards. The prototype has successfully delivered fantastic surfing waves, demonstrating the strength of this amazing concept.
