Frequently Asked Questions — Maritime Energy & Decarbonization
What does VISSH MARINE specialize in?
VISSH MARINE delivers data-driven maritime decarbonisation, energy efficiency, and regulatory compliance solutions. We offer Energy Saving Devices (ESDs), digital analytics, AI/ML, and consulting for shipowners and operators worldwide.
Which vessel types benefit most from your solutions?
Deep-sea bulkers, tankers, and container ships on long-haul, steady routes (13–16 knots) achieve the highest ROI (2–5 years). Short-sea feeders benefit mainly for regulatory compliance upgrades.
What regions do you serve?
We operate globally, with strong demand in Europe, China, USA, and projects across Asia, Middle East, South America, and Africa.
What is EEOI (Energy Efficiency Operational Indicator)?
EEOI is an IMO metric that measures CO₂ emissions per ton-mile, helping operators monitor real-world operational efficiency and identify improvement areas.
What is EEXI (Energy Efficiency Existing Ship Index)?
EEXI measures the technical efficiency of existing ships' design and propulsion. Compliance may require technical or operational upgrades.
What is CII (Carbon Intensity Indicator)?
CII rates a ship's annual operational efficiency (A–E) based on CO₂ emissions per transport work. Low ratings require corrective actions for compliance.
What is EDVI (Energy Efficiency Design Value Index)?
EDVI benchmarks the energy efficiency of newbuilds during design and construction, ensuring emission standards are met.
What are Energy Saving Devices (ESDs) and how do they work?
ESDs are retrofittable technologies—like propeller ducts, fins, and air lubrication systems—that improve hydrodynamic efficiency, reduce fuel use, and cut emissions.
What is the ROI for ESDs and EETs?
ROI typically ranges from 2–5 years, depending on vessel type, operating profile, and fuel costs. Long-haul vessels and high-utilisation ships see the fastest returns.
What are the typical downtime requirements for ESD installation?
Propeller devices: 2–5 days (docking required); Hull-based ESDs: 4–7 days (drydock); Air lubrication: 7–14+ days; Wind-assisted propulsion: 5–10 days; Advanced coatings: 2–4 days. Installations are aligned with drydock cycles and cargo schedules.
What certifications must shipyard personnel have for ESD installation?
Energy awareness & IMO compliance (EEXI, CII, SEEMP); Certified Energy Manager (CEM) for supervisors; Welding, coatings, automation, and rigging certifications; OEM-specific installation modules; Annual recertification per ISO 50001/14001.
What QC and inspection procedures are required?
Material certification, dimensional inspections (3D scanning), non-destructive weld testing, Factory Acceptance Tests (hydrodynamic, load, calibration), pre-install checks, mock assembly, function testing, class and flag witnessing before release.
What is a Digital Twin and how is it used in shipping?
A Digital Twin is a virtual replica of a ship or system, enabling real-time monitoring, predictive maintenance, and performance simulation to optimise operations.
How do IoT and IoE enhance energy efficiency?
IoT/IoE connect shipboard systems for seamless data collection and analytics, improving decision-making and supporting predictive maintenance.
How do AI and ML improve maritime operations?
AI/ML enable predictive maintenance, route optimisation, anomaly detection, and automated compliance—reducing downtime and increasing efficiency.
What is predictive maintenance?
Predictive maintenance uses real-time data and analytics to predict equipment failures, minimising downtime and repair costs.
How does performance monitoring contribute to efficiency?
Performance monitoring analyses shipboard data to track energy use, identify inefficiencies, and provide actionable optimisation insights.
What is an Energy Management System (EMS)?
An EMS monitors, controls, and optimises onboard energy use, integrating data for efficient operations and regulatory compliance.
What are the benefits of digital monitoring?
Digital monitoring provides real-time performance tracking, remote troubleshooting, and automated reporting, enhancing efficiency and compliance.
What is Superintendent AI?
Superintendent AI refers to advanced analytics tools for fleet managers, enabling predictive maintenance, compliance tracking, and performance optimisation.
What is the EU Biocidal Products Regulation (EU BPR) and does it apply to my vessel?
The EU BPR (528/2012) applies to all biocidal products (chemicals, coatings, MGPS) used on vessels in EU waters, regardless of flag or build location.
What is Article 95?
Article 95 is the EU's official list of authorised suppliers for biocidal substances. Only products from Article 95-listed suppliers are legal in the EU.
Does the EU BPR apply to MGPS, paint, or coating systems?
Yes. All marine growth prevention systems and coatings must comply with EU BPR if used in EU waters.
Does the EU BPR apply to ICCP systems?
No, ICCP systems are not covered by the EU BPR.
What are the penalties for non-compliance with EU BPR?
Penalties vary by country (e.g., up to £5,000 in the UK), and may include fines or imprisonment.
Is special crew training required for EU BPR compliance?
No special training is required for EU BPR.
What is FuelEU Maritime?
FuelEU Maritime (effective 2025) is an EU regulation promoting decarbonisation of shipboard energy. It sets lifecycle GHG intensity limits, mandates on-shore power supply (OPS) for certain vessels, and requires use of renewable fuels.
Who is responsible for FuelEU Maritime compliance?
The ISM company (DOC holder) is responsible, regardless of whether it is the shipowner, manager, or bareboat charterer.
What ships are covered by FuelEU Maritime?
Ships over 5,000 GT arriving at or departing from EU/EEA ports.
How is GHG intensity calculated and confirmed under FuelEU Maritime?
GHG intensity is calculated on a lifecycle (well-to-wake) basis for CO₂, CH₄, and N₂O. Data is collected under the FuelEU Monitoring Plan and verified annually.
What is banking, borrowing, and pooling in FuelEU Maritime?
Banking: Carry forward surplus GHG compliance to the next year. Borrowing: Use future compliance credits in advance (with penalty). Pooling: Offset deficits and surpluses among ships in a fleet for the same year.
What are the OPS and RFNBO requirements?
OPS: From 2030, containerships and passenger ships >5,000 GT must use on-shore power at designated EU ports. RFNBO: From 2034, if sector-wide usage is below 1% in 2031, ships must use at least 2% RFNBO annually.
What are the penalties for non-compliance with FuelEU Maritime?
Penalties are calculated based on excess GHG, energy use, or failure to use OPS/RFNBO. Persistent non-compliance can result in expulsion from EU ports.
How are FuelEU Monitoring Plan and FuelEU Report managed?
The ISM company submits a Monitoring Plan via THETIS-MRV before the start of each year, and an annual FuelEU Report after year-end. Compliance is verified before a Document of Compliance is issued.
What is your project management approach?
We define CRM milestones (outreach → ROI validation → negotiation), assign clear roles, provide bi-weekly updates, and use version-controlled documentation.
What is your pricing model?
We offer fixed-fee and subscription-based pricing. Typical contracts are $5,000–$10,000/month; custom ESDs are $5,000–$20,000 higher than standard.
What payment terms are available?
Standard: 20% on order, 50% before delivery, 30% after delivery but before vessel departure.
Can you share project outcomes?
Our ESD projects have delivered 6–8% fuel savings for clients such as GMS and Kyra. Over 20% of clients return for further improvements.
