Retrofit of BWT and EGC systems

A meeting with Goltens Oslo AS under Nor-Shipping 2019 led to an exciting collaboration where BEIN Engineering AS was tasked with designing the electrical part of a retrofit of scrubber and ballast water management systems.

Goltens is an established system integrator that supplies Exhaust Gas Cleaning (EGC) and Ballast Water Treatment (BWT) systems to ships. As a result of the new IMO rules for emissions, many ships had to retrofit scrubbers for cleaning exhaust by year-end 19/20. See more about IMO 2020 here. This has opened up a market with great potential and short delivery times. It is exactly this kind of challenge that is a match for BEIN Engineering.

BEIN met Goltens during the NOR-Shipping trade fair 2019 and arranged a meeting for a mutual presentation. Both companies are located close to each other at Alnabru / Brobekk in Oslo. What was supposed to be just a meeting to get to know each other, turned out to be the start of a project collaboration on retrofit of EGC and BWT systems on a bulk carrier for one of the Goltens’ end customers.

The task was to design the electrical system for BWT and EGC, which had to be installed as a retrofit on board the vessel belonging to one of Goltens’ customers. The job included electrical engineering calculations, designs and drawings. We calculated a new load balance as the basis for selecting new switches and cables for the installation.

  • Electrotechnical calculations, designs and drawings
  • Documentation
  • Classification and approval of retrofit

We also performed cable calculations, selectivity analysis and wrote documentation for the class and yard duties. The biggest challenge was that since this was a retrofit, we had little space for the components, so we had to be careful to find an optimal solution. We also drew diagrams and layouts for new boards and changes in MSB / ESB, Ship Interface, IO and E-stop stations for both systems (BWT and EGC).

This project has added further valuable experience to our expertise in vessel electro, and we have become acquainted with a local player in a highly relevant area.
