Where Manifesto fits in the IHM process
The IHM Part I development process for existing ships is defined in 5 steps by MEPC.379(80) §4.2.1. Manifesto formally delivers step 3 — the Visual/Sampling Check Plan (VSCP) — feeding the accredited surveyor who carries out steps 4 and 5.
Collection of necessary information
Technical documentation of the ship: plans, manuals, certificates, supplier MD/SDoC, maintenance records, sister-ship data. Conducted by the shipowner.
Assessment of collected information
Document analysis to identify equipment, systems, and areas that contain or potentially contain Table A and B materials. Mandatory coverage of Table A; Table B as far as practicable.
Preparation of the Visual/Sampling Check Plan (VSCP)
← Manifesto delivers hereClassification into 3 lists: (a) visual check; (b) laboratory sampling; (c) PCHM — Potentially Containing Hazardous Material. This is the step delivered by Manifesto, enriched with a photogrammetric 3D model, AI-assisted visual screening, and cryptographic attestation.
Onboard visual / sampling check
The accredited surveyor executes, based on the VSCP, visual inspection and sample collection in prioritized areas and equipment. Samples go to an ISO/IEC 17025-accredited laboratory.
Preparation of the official IHM Part I
The surveyor compiles IHM Part I based on the results of the previous steps and supplier declarations. The official document is issued by the Recognized Organization (RO) or flag Administration.
PCHM — Potentially Containing Hazardous Material
MEPC.379(80) §4.2.7.1.3 and §4.2.8.3 formally provide for the PCHM classification of equipment, systems, and areas that cannot be visually verified or sampled without compromising operational safety or unit efficiency.
These points — confined spaces, materials under insulation, internal casings, submerged areas — receive georeferenced mapping by Manifesto and a formal justification of inaccessibility for aerial inspection. The accredited surveyor revisits these points within an appropriate window (drydock, refit, conversion).
Technical gaps of the photogrammetric layer are not product weaknesses — they are valid regulatory classifications which Manifesto documents in a structured way.
Equipment varies by unit class
The Manifesto photogrammetric layer is dimensioned according to the unit's size and complexity. For units outside the range served by a civilian drone, we integrate with a specialized provider of industrial RTK drone or inspection ROV.
| Unit class | Appropriate equipment | Coverage |
|---|---|---|
| Up to 100m (PSV, AHTS, tug, barge) | Consumer-grade civilian drone (DJI Mini 2 or equivalent) | Topside and emerged hull in calm waters |
| 100–200m (small bulk feeder, small container) | Industrial RTK drone (Mavic 3 Enterprise RTK or equivalent) | Topside and emerged hull with centimetric precision |
| Above 200m (FPSO, drillship, semi-sub topside) | Industrial RTK drone + operator authorization + airspace planning | Topside and emerged hull, within authorized window |
| Submerged areas (hull, risers, manifolds, mooring) | Inspection ROV via specialized partnership | Out of aerial survey scope |
| Confined internal areas (cofferdams, tanks, double bottoms) | Indoor drone (Skydio X10, Flyability Elios 3) or traditional inspection with PPE | Out of aerial scope — eligible for PCHM |
The cryptographic attestation layer (TEE) implemented in Manifesto is proprietary technology under Brazilian-registered Intellectual Property. The methodology for generating the VSCP via photogrammetric digital twin with AI-assisted visual screening and cryptographic audit chain constitutes an intellectual asset of Veridis Ambiental.
The document generated by Manifesto, carrying TEE cryptographic attestation, is itself a protected artifact — any reproduction or methodological replication is subject to Veridis Ambiental's intellectual property rights.
