Projects

Blast and shock modelling Phase 3 (2021 - 2023)$364,769
Description
The objective of this project is to further develop blast and shock modelling capability to assist in the through-life assessment and management of a surface vessel. This is particularly relevant for the SEA5000 future frigate platform as Australian Defence consider the design service life of the new warship and current fleet. The key questions for operational and life cycle management of a platform include: how you assess the Assessed Age of a current warship, how you determine whether the service life of a warship can be extended (Life-of-Type (L-o-T) Extension) and what operational or management practices can a warship manager use to enhance the life of a warship and to correctly assess its vulnerability.

Description
The project aims at conducting a high-level analysis and a comprehensive literature review on three potential zones for offshore wind developments in Tasmania in terms of site-specific environmental parameters and supporting information about supply chain and logistics. The outcomes of this study will better inform decision-makers and developers on the feasibility and suitability of such zones for offshore wind developments in Tasmania.

Thermal Oil Heating System Energy Balance: Spirit of Tasmania Vessels (2020 - 2021)$8,261
Description
The Spirit of Tasmania operated by TT Line Company Pty. Ltd. uses a low sulphur fuel oil to comply with the 1 January 2020 low sulphur limit. This new fuel type has resulted in operational changes on the vessel that affect the Heating Load requirements of the installed Thermal Oil Heating System. The thermal oil heating system on the vessels provides heating for hotel services, auxiliary equipment and most importantly heating required for burning traditional bunker fuels in the ships diesel engines.The low sulphur fuel oil does not require as much heating in comparison to heavy fuel oil. The projects aim is to undertake an energy balance on the thermal oil heating system to quantify the savings at sea and port. The energy audit will further provide answer for the following questions.1.How much has been saved in energy, fuel consumption and greenhouse gas terms due to the reduction in fuel heating because of burning low sulphur fuel oil?2.Can any improvements be made to the 20-year-old Thermal Oil System to optimise its performance due to the reduced demand for heating?3.Are there any operational changes that could be affected due to the reduced heating demand?4.Can the thermal oil system be heated to a temperature lower than 190 ⁰C?5.Knowing what we know now, are there any new technologies that could be implemented to make further savings?
