Standard documentation packs to confirm class/flag compliance.
Proven durability and long-term support so replacements don’t just fit—they last.
4-Step Yard Workflow
STEP ONE ASSESS
Capture install space dimensions, access routes, utility connection locations, and class/flag requirements.
STEP TWO CONFIGURE
Engineer the retrofit package with options and recommended spares to fit your vessel program.
STEP THREE PROPOSE
Deliver a detailed plan with fit drawings, documentation package, and downtime estimate.
STEP FOUR DELIVER SUPPORT
Install and commission during service or short yard periods, with training, handover, and long-term support.

FREQUENTLY ASKED QUESTION
How fast can a replacement system be installed and brought online?
Our brownfield modules are designed around your existing tie-ins and access routes, so installation is measured in hours or days—not weeks. Systems are fully function-tested before shipment to minimize offshore hookup time and speed commissioning.
Can your systems fit through our hatches and stairwells?
Yes. All modules are dimensioned for offshore access limits. We break down systems into subassemblies sized to pass through hatches, ladders, and stairwells, then reassemble offshore for a clean tie-in.
Will the new system match our existing piping and electrical tie-points?
Replacements are engineered to your legacy connection dimensions. Tie-in points are confirmed during the assessment phase so you don’t face field modifications or unplanned hot work offshore.
