Installation Sequencing
● Translate machinery arrangements, vendor installation/alignment manuals, and shaft line calculations into step-by-step installation work instructions.
● Define installation sequence relative to hull construction and erection, including what must happen before erection, after hull closure, or only once the vessel is afloat.
● Coordinate with structural, electrical, piping, and HVAC planning to ensure foundations and interfacing systems are ready at the right stage.
Foundation & Alignment Procedures
● Specify foundation chocking, grouting, and bolt torque/sequence requirements.
● Define alignment procedures (sag/gap, laser/optical alignment, bearing load checks) and sequence shaft line installation relative to hull deflection, launch, and dock trial milestones.
● Define rigging, lifting, and handling plans for heavy machinery moves.
Anchor & Ramp Systems Planning
● Define installation and sequencing requirements for anchor handling systems, including windlass/winch foundations, chain locker and hawsepipe arrangements, and anchor stowage and deployment components.
● Plan installation, fit-up, and functional test sequencing for bow/stern ramp systems and ramp lowering/actuation systems specific to LCU-type vessel programs, including hydraulic or mechanical actuation components, hinge and pin arrangements, and ramp locking/securing mechanisms.
● Coordinate ramp and anchor system installation with structural closure, coatings, and electrical/hydraulic system planning to ensure components are installed and tested at the correct build stage.
Quality & Acceptance Criteria
● Specify inspection hold points and acceptance criteria (foundation flatness, alignment tolerance, bolt torque, NDT of critical welds) across propulsion, anchor, and ramp systems.
● Define functional test and operational checkout requirements for anchor handling and ramp lowering systems prior to sea trials.
● Coordinate with quality assurance and vendor technical representatives on inspection and acceptance.
● Ensure instructions reflect ABS, USCG, NAVSEA requirements, vendor warranty terms, and documentation needs through sea trials.
Production Support & Continuous Improvement
● Support first-article installations and witness alignment checks, functional tests, and sea trials where needed.
● Refine installation procedures based on floor feedback, vendor guidance, and lessons learned.
● Maintain installation and alignment documentation standards across the program.
What Success Looks Like
● Propulsion and machinery installations meet alignment and tolerance requirements on the first attempt.
● Anchor handling and ramp lowering systems are installed and function correctly on the first functional test.
● Shaft line alignment remains valid through launch, dock trials, and sea trials.
● Installation sequence avoids rework from hull deflection or premature installation.
● Inspection hold points catch issues before they compound into equipment damage.
● Production, quality, and vendor representatives trust the installation plan as an accurate reference across all machinery systems.
