Active Chief EngineerMANTIS is built by a working Chief Engineer who remains directly involved in vessel construction and operations.Why MANTIS was built

More than a decade at seaProduct decisions come from practical maritime and IHM experience, not a software-only view of the work.

Purpose-built for IHMDesigned to replace outdated options and the hours spent rebuilding evidence from disconnected files.

How MANTIS works

From vessel change to survey ready.

MANTIS vessel IHM inventory screen — MANTIS interface shown with demo vessel data: inventory, certificates, supplier evidence, audit trail, and exports.

01Record the change

Log materials, equipment, coatings, refrigerants, stores, certificates, and findings as work happens.

02Attach the evidence

Send secure no-login upload links for supplier MD, SDoC, SDS, certificates, photos, and supporting files.

03Hand over the proof

Export the inventory and change log as a PDF, or build a ZIP with evidence files, certificates, a spreadsheet backup, and an optional audit trail.

MANTIS keeps the IHM maintenance loop visible: record what changed, attach the evidence, and export the proof when class, flag, PSC, or management asks.

Actual export

Inspect the survey pack before you start a trial.

Choose the nine-page survey summary for a quick review, or download the full evidence archive. Both are generated from the same fictional vessel dataset using the exporters in MANTIS.

HKCHong Kong Convention

International IHM framework for ships within the Convention's scope.

EU SRREU Ship Recycling Regulation

EU-flagged ships and the Article 12 route for in-scope third-country port calls.

MEPC.379(80)Current IMO guideline

Part I/II/III structure, declarations, and supporting evidence.

BoundarySoftware, not certification

The flag administration or an organisation it authorises performs formal verification and certification.

Data ownership

Your vessel data stays yours.

MANTIS is built so the IHM record remains portable. Records, supplier evidence, uploaded documents, audit history, and survey packs can be exported when your team needs to hand over, review, or leave the system.

Full archive exportDownload structured records with uploaded evidence files, not just a spreadsheet.

Survey and transfer packsProduce reviewer-ready exports for class, flag, PSC, management, or vessel handover.

No inbox dependencySupplier files and upload history stay attached to the vessel record.

Operational features

The workflows operators actually need.

MANTIS covers the daily operating work behind IHM maintenance: fleet visibility, supplier document chasing, change history, and exports that can be used outside the app.

Fleet operationsSearch, filter, and review vessel readiness across the fleet.

Owned and shared vessels, relationship badges, risk signals, archived vessels, and role-aware actions in one operational view.

Supplier evidenceRequest MD, SDoC, SDS, and certificates without inbox chasing.

Saved suppliers, secure no-login upload links, delivered-document history, request status, and audit context.

Export controlKeep usable copies of the record and evidence.

Excel backups, survey packs, transfer packages, and full archive exports keep the IHM record portable.

Audit trailTrace changes, uploads, reviews, and sensitive events.

Material changes, supplier activity, export requests, billing events, and role changes are designed for reviewability.

Self-serve access

Why MANTIS?

MANTIS fills the gap between spreadsheets, class-specific tools, and managed HazMat services: a class-agnostic IHM workspace your team can keep current vessel by vessel.

Class tool	Ideal for single-class workflows. Less flexible across mixed vessels, flags, or societies.
Managed service	Ideal when IHM maintenance is fully outsourced. Higher cost and less ownership of the live record.
Spreadsheet	Ideal for simple records with low change volume. The pack still has to be rebuilt from folders and inboxes.
MANTIS	Ideal for operators who need control of the live IHM record. Supplier evidence, audit trail, and survey exports stay in one place.
