Commissioning Scope
Four Pivotal Phases in Commissioning & Delivery
Verifying that every machinery subsystem, auxiliary plant, and automated safety interlock performs rigorously under authentic marine operating loads.
- Comprehensive Commissioning Master Plan: Establishing testing matrices, pre-trial checklists, auxiliary system firing sequences, and safety interlock matrices.
- FAT & HAT Witnessing: Overseeing factory tests for critical propulsion, boiler, and steering equipment, followed by live dockside tests prior to sea trial clearance.
- Full Sea Trial Supervision: Stationed onboard throughout full endurance trials to verify engine power, vessel speed, specific fuel consumption, vibration, and noise levels.
- Punch List Management & Handover Dossier: Systematically classifying defects, supervising shipyard rectifications, and verifying complete statutory as-built documentation.
