Project facts

Ship Type: Offshore Supply Vessel

Gross Tonnage: 4071

Length Overall: 88.8 m

Class: Bureau Veritas

BWTS: 250 m3/h

13 BWTS experts: 1 Scan & Survey Team + 1 Design Team + 1 InstallationRiding Crew

2 days – Feasibility

15 days – Complete Design

25 days – Installation during voyage

 

Key factors for a successful installation

  • Excellent planning & logistics management
  • Detailed preparation of all the required materials and pre-checking of Vendor’s deliveries
  • Adopting optimized strategy for connecting with Vessel’s existing systems without affecting functionality
  • Preparing Installation Procedure and daily list of works

 

 

Phase 1: Feasibility Study & 3D laser scanning

Team: 1 experienced marine surveyor + 1 laser scan technician

Dedicated team deployed to Cyprus where ship was berthed.

Phase 2: Basic and Class

Approval

Team: 1 Lead Piping Design Engineer + 1 electrical design engineer Engineering team prepared documents for basic design in accordance with international regulations. The focus is placed upon engineering an optimal integration of the BWTS in the ship systems, making sure that all previous systems are operating without any problems and the electrical monitoring is performed correctly.

 

Phase 3: Detail Design

Team: 1 Team Leader + 1 Piping detail design engineer

Dedicated team deployed to Cyprus where ship was berthed.

Detail design started right after basic design was completed. Class approval contact was maintained, and detail design finished before class approval was received with no impact from class comments.

 

Phase 4: Prefabrication &

procurement

Team: 1 PM + 1 Procurement Manager

GLO MARINE provided prefabrication of piping spools and outfittings according to approved documentation.

We also provided full procurement & logistics for all elements required in the

installation: electrical panels, cables, pumps, valves, free routing pipes including prefabricated air manifold.

 

 

Phase 5: Installation

Team: 1 Technical Supervisor, Riding Crew of 5 Pipe Fitters and 1 Team Leader Electrician

 

The complete system installation was carried out using a riding crew of 7 people

during a short voyage of only 25 days. Our installation team overcame all minor

setbacks and managed to complete the job successfully in precisely the agreed timeframe.

 

The result

The installation of the ballast water treatment system was completed only during voyage in an excellent timeframe of 25 days, as demanded by the client, in order not to have even a day of downtime.

As a result of the accuracy of the scanning and the excellent collaboration between the planning and engineering departments, the project was executed millimeter level accuracy.

Relevant details:

materials were prefabricated / procured in Galati

mobilization of equipment – Spain

mobilization of personnel – Spain and Gibraltar

the system was ready for commissioning in 25 days before reaching its destination
