(Industrial Patent n°102016000036266)
- Elimination of added resistance from tunnels while at sea in all operational conditions
- Sensible reduction of acoustic noise due to fluid turbulence in the hull regions interested by the presence of thruster tunnels (efficacy proven on already refitted naval vessel)
- Improvement of thrust performance as a result of the elimination of conventional tunnel grids
- Turn-key services
- existing thruster region surface laser scan
- 3D modelling of tunnel hatches
- Consolidated partnership with engineering companies for CFD calculation and/or towing tank model tests aimed at new geometry pre-installation assessment
- new hatches structure design
- Hull Block layout
- Scantling plan drawings
- Parts and structure report
- Workshop documentation
- Mechanical installation details
- Closing mechanism and hydraulic pistons design
- Hydraulic system P&I diagrams
- Electrical & Automation P&I diagrams
- Installation Plan preparation
- On-site installation supervision
