Naval architecture sign-off pathway
Stability booklet updates, mooring approvals, hull girder reinforcement studies, compartment watertight recert flows run before steel cutting.
Drydock
Conversion & lengthening
Conversion and lengthening programs re-engineer hull structures, compartments, and systems so vessels adopt new cargoes, rules, or trading roles without greenfield orders. Naval architects steward stability cases, docking plans, weld procedures, coatings, sea trials, and class endorsements while the yard sequences steel, outfitting, and machinery vendors. The service fits owners modernising tankers into storage, extending container capacity, or inserting LNG-ready sections under supervised change control.
What you get
Heavy steel & outfit integration
Yard aligns block assembly, docking blocks, synchrolift choreography, blasting cycles, coatings, LNG tank conversions, mooring retrofit outfitting scopes.
Commissioning liaison with operators
Sea trials, horsepower verification, instrumentation recalibration, load computer checks line up alongside class surveyors preventing insurance gaps.
How it works
- 1
Baseline survey & class intent
Structural gauging captures wastage allowances, docking plan locks dates, naval architects reconcile conversion brief with IMO / flag rules before capex approval.
- 2
Engineering fabrication package
Detail drawings for inserts, lengthening sections, stern scoop blocks, LNG tank stubs get POs while outfit vendors schedule long-lead cranes and deck machinery deliveries.
- 3
Drydock execution & inspections
Alignment lasers track section seating, weld NDT regimes log evidence, blasting and coating inspectors release hold points only when climatic windows match spec.
- 4
Trials & redelivery dossier
Inclining tests refresh stability books, engine shop trials verify KPIs, handover binders consolidate certificates for charterers insurers port state MOUs alike.
