Cost analysis and improvements after design change of overflow protection for tanker vessels (English)
Abstract [en]

This report covers a project conceived by and performed for Aspervall Instruments AB in collaboration with Vimex AS. It is a part of the course degree project of Bachelor of Science in Mechanical Engineering, MSGC17, at Karlstad University, the faculty of health, science and technology.

The overflow protection for primary tanker vessels has been on the market for many years, and it is viewed as unique and dependable construction. The product measures and indicates the level of liquid petrochemical products, and the most common model has three levels of indication: 95 – 98,5 – 99  %. During the last few year other manufacturer from Asia have started competing with cheaper products. Due to this, Vimex who sell the products have to reduce the prices to be able to compete.

A design update have therefore been launched by Vimex with the objective to reduce production costs with 20%. This degree project aim to investigate how much the new design would cost. The project also involve looking at the whole value chain during manufacturing, and how this can be streamlined.

The project passed four different stages. The first was project planning with a time chart, risk management and description of organization. The second and third were current and future design and production. During these stages information regarding design and production were collected and a future scenario was sketched. The economic parts were calculated and compiled. Last stage assembly were focused on the assembly.

As a conclusion the cost reduction target of 20 % is almost achieved with the new design, but during the project it appeared that Vimex wants to reduce the cost another 10 %. To accomplish this more changes have to be done, both in design and manufacturing process.
