BWT system guide plan

Goltens Green Technologies provides shipowners with the decision support they need when selecting a ballast water treatment system. Key considerations are space, power, ballasting capacity, voyage patterns and special requirements such as the need for meeting EX requirements.

An onboard survey to make a visual inspection of where to tie-in the system, take measurements and optionally make a 3D laser scan of the installation space ensures that subsequent engineering design is based on the actual configuration of the ship. Often, particularly for older vessels, existing drawings are inaccurate. The survey is also used to evaluate how the system can be brought on board and whether or not it will be possible to undertake all or part of the installation on voyage.

Back at the engineering centre, preengineering work is carried out to identify the key design issues, check load balance, modify ballast diagrams and prepare a detailed quote. There will be no surprises for the shipowner after this detailed analysis and the feasibility of the chosen system will be confirmed.

A detailed design phase includes preparation of the isometric drawings of piping and the construction drawings to meet class requirements. A part list and an updated ballast water management plan will also be prepared. Goltens has established a reputation for delivering highly skilled teams for the most critical repair projects that shipowners have. Our experience with class requirements and our on-going analysis of the technologies and legislative requirements helps shipowners achieve the milestone of class approval as smoothly as possible.

Purchasing of equipment and prefabrication of piping and foundations is made simple by the thorough specifications already developed. Assorted ancillary materials such as cabling and valves are included in the purchasing to ensure there are no delays once installation commences.

Goltens can provide installation, commissioning and crew training services worldwide. Our services include full electrical installation. Minimising operational downtime can involve various approaches in the way the installation stages are conducted including partial work done during drydocking, alongside or at sea. Worldwide availability of Goltens’ installation teams means voyage patterns can be maintained with minimal disruption.

Possibly the most critical step long-term, Goltens provides ongoing support and service worldwide. Goltens Green Technologies aims to be a longterm partner to shipowners as they meet the growing number of environmental requirements being enacted by IMO. In the future, these services will be expanded to cover equipment such as air emissions abatement and other technologies.
