Marine Biofuel Compatibility, Fuel Changeover & Engine Readiness Tool

Screen the actual barriers to introducing FAME or HVO blends: fuel specification, engine and auxiliary approvals, tank and seal compatibility, water and stability, cold-flow properties, purification, return-line segregation and a recoverable changeover. Build an evidence-backed transition plan rather than assuming that an ISO fuel grade guarantees machinery acceptance.

Fast fuel-transition screen: 11 inputsAssess the key permissions and practical safeguards before ordering bunkers. The default values are illustrative and do not imply approval. A missing OEM acceptance cannot be overridden by a low numeric score.

Fuel & System Snapshot

Engineering transition assessmentEnter supplier-tested fuel properties and maker-approved operating limits. Advanced registers capture equipment pathways, individual tanks and execution steps. Empty optional technical limits remain unverified rather than assumed compliant.

Operational boundary: This tool does not certify ISO compliance, engine acceptance, class/flag approval, MARPOL compliance or a safe changeover. It does not instruct valve operations. Any actual fuel change, viscosity/temperature setting, purifier adjustment, return-line configuration or trial must follow vessel-specific maker guidance, SMS procedures and authorized engineering review.

Equipment & Engine Compatibility Register

Record each fuel-consuming unit or fuel-treatment component separately. An unapproved main engine, critical auxiliary or return-flow pathway remains a hold point even when other systems are ready.

Use	Unit / equipment	Role	Maker acceptance	Seals / materials	Viscosity fit	Fuel supply route	Critical duty	Evidence reference	Exposure	Remove

Tank / Transfer / Return-Line Register

Record selected storage, settling, service and return arrangements. Mixing compatibility must be established by actual test/approval when necessary. Segregation is not automatically assumed safe.

Use	Tank / line	Function	Fuel residual	Clean / dry	Coating / seal	Blend compatibility	Water drain	Return isolation	Exposure	Remove

Controlled Trial & Acceptance Register

Build the ship-specific sequence, owners, verification evidence and hold points. Status is advisory. Unresolved mandatory tasks prevent a ready-to-proceed indication.
