Sector 03
Marine, Vessels & Conversions
Owner-side and shipyard engineering across the full vessel lifecycle — to 10+ class societies. Newbuild vessel design from concept through class approval, OSV-to-WSV conversions, pre-purchase assessments that deliver measurable cost savings, and life-extension of in-service vessels.
Capabilities
Newbuild Vessel Design
- Concept design — GA, lines plan and parametric studies
- Hull form optimisation and CFD — resistance, propulsion, EEDI/EEXI (OpenFOAM / ANSYS Fluent)
- Class approval packages — ABS, DNV, LR, BV, IRS, NK, KR, BKI, RINA, CCS
- Production engineering — nesting plans and fabrication support drawings
Conversions & Modifications
- OSV → WSV / Walk-to-Work conversion — deckhouse structure, gangway integration
- Barge → Pipe-Lay Barge — and mission-specific modifications
- LNG Carrier → FSRU conversion — naval architecture scope, stability, mooring
- Vessel modification, refit and structural life extension
Stability, Hydrodynamics & Advisory
- Intact and damage stability — IMO IS Code, SOLAS, MARPOL, MODU; deterministic and probabilistic
- Seakeeping and global performance analysis — RAOs, motion criteria, air-gap
- Mooring and DP capability analysis — OCIMF MEG4, IMCA M 166, OrcaFlex
- Pre-purchase and pre-charter condition assessment
