OPTION 1

INSPECTION • REPORTING
 

Scope and Extend: Our technicians carry out an inspection onboard the vessel during dry docking or when in port in order to investigate feasibility of installation of the ERMA FIRST Ballast Water Treatment System (BWTS).

Estimated Time of Delivery: One (1) week after completion of the survey on board. Attendance on board lasts one day.

Deliverables: A report with the survey findings in electronic format (.pdf).

OPTION 2

INSPECTION • 3D LASER SCANNING • REPORTING

 

Scope and Extend: Two technicians carry out an inspection on board the vessel during dry docking or when in port in order to investigate feasibility of installation of the ERMA FIRST Ballast Water Treatment System (BWTS). All necessary areas will be scanned with a 3D Laser scanner and the generated PDF file will be used to evaluate/verify the different installation layouts.

Estimated Time of Delivery: One (1) week after completion of the survey on board. Attendance on board lasts one day.

Deliverables: A report with the survey findings in electronic format (.pdf).

 

OPTION 3

INSPECTION • 3D LASER SCANNING • FEASIBILITY STUDY • ENGINEERING STUDY • RETROFIT SPECIFICATIONS

 

Scope and Extend: Attendance by two engineers onboard the vessel during dry docking or when in port, in order to investigate feasibility of installation of the ERMA FIRST Ballast Water Treatment System (BWTS). All necessary areas will be scanned with a 3D Laser scanner and the generated point cloud will be used to evaluate/verify the different installation layouts.

After completion of scanning, 3D modeling of the main piping will be performed. The 3D modeling is being reviewed by using the output of the 3D scans of the areas chosen for new equipment components’ installation so as to evaluate their preliminary arrangement feasibility. These feasibility study results will be taken into consideration for the selection of the system, of which installation will be further studied and is considered to be the first stage of the installation study.

Performance of an engineering study for BWTS installation, based on available documentation and onboard survey results, including complete proposal with ballast water treatment system modeling, routing of piping (including piping isometric drawings, materials and parts list), specification of structure and outfitting modifications and Class required drawings.

Preparation of all necessary modifications of the “as built” drawings (structural, piping, outfitting, electrical).

Submittal of those drawings specified to the Client for their comment and approval. On receipt of the Client’s comments, ERMA FIRST will revise the affected drawings accordingly to obtain the necessary approvals.

Preparation of the required drawings, which will be submitted to vessel’s Classification Society and/ or Flag State as necessary, for approval.

Preparation of technical specification of modification/ retrofitting, in order to be submitted to various shipyards or repair facilities for receiving quotations.

Estimated Time of Delivery: Twenty (20) weeks after completion of the survey on board. Attendance onboard lasts one day.

Deliverables: A report with the survey findings in electronic format. Also, all 3D scan files will be given to the Client.

A detailed report with the preliminary arrangement for the BWTS, including 3D model of the equipment, the basic piping systems and their location in the point cloud created after 3D laser scanning, for reference, followed by a detailed report of the study’s outcome and a presentation at the Client’s premises or a teleconference (at Client’s discretion) will be this project’s deliverables.

The deliverable engineering study file shall include:

  • Isometric piping drawings (with materials’ and parts’ list)
  • Detailed piping sections/ spools
  • Modifications of the affected “as built” structural, outfitting, diagrammatic piping and single line electrical drawings
  • Class approved drawings
  • Technical specification of installation and related modification works

ERMA FIRST is committed to work closely with the Classification Society, with absolute confidentiality and continuous communication of information.

OPTION 4

SUPERVISION OF RETROFIT WORKS

 

Scope and Extend: One experienced ERMA FIRST Engineer will attend the modification works in order to survey them and to ensure that installation study and various drawings are being followed by the shipyard, repair facility or riding crew.
