Modern battery systems represent a significant investment for vessel owners and operators. As battery fleets mature, understanding their condition, performance, and remaining operational life becomes increasingly important.

OceanGrid provides independent battery health and lifecycle advisory services to help operators maximize asset value, reduce operational risk, and make informed decisions regarding maintenance, refurbishment, and replacement strategies.

Whether supporting a single vessel or an entire fleet, our focus is simple: maximize reliability, extend service life, and ensure batteries continue to perform safely and efficiently throughout their operational lifecycle.

OceanGrid performs comprehensive battery health assessments designed to provide a clear understanding of system condition and future performance.

Assessments may include:

• State of Health (SOH) evaluation
• Capacity degradation analysis
• Operational performance review
• Historical trend analysis
• Remaining Useful Life (RUL) estimation
• Risk identification and mitigation recommendations

Deliverables include a detailed technical report outlining current system condition, identified concerns, and recommended actions.

Battery replacement is not always the most economical solution.

OceanGrid assists owners in evaluating whether refurbishment, repair, module replacement, or system upgrades can provide a viable alternative to complete system replacement.

Studies may include:

• Technical viability assessments
• Repair versus replacement evaluations
• Cost-benefit analysis
• Lifecycle extension opportunities
• Operational and safety considerations

Our objective is to provide practical recommendations based on technical and commercial realities.

OceanGrid acts as an independent technical representative for vessel owners, operators, financiers, and project stakeholders.

Support may include:

• Warranty investigations
• Battery failure assessments
• FAT and CAT witness services
• Technical dispute support
• Acceptance testing reviews
• Independent technical opinions

Our independence ensures recommendations are based on operational performance and technical evidence rather than product sales objectives.

OceanGrid supports the commissioning of new battery systems and the recommissioning of existing installations following refurbishment, repair, relocation, or major upgrades.

Services include:

• FAT and CAT support
• Installation verification
• Functional testing
• Operational readiness assessments
• Documentation review
• Owner acceptance support

Our experience helps ensure systems are commissioned safely, efficiently, and in accordance with project requirements.

As battery fleets grow, long-term planning becomes critical.

OceanGrid assists operators in developing lifecycle management strategies that improve predictability, reduce risk, and optimize capital expenditure.

Services may include:

• Fleet condition monitoring
• Replacement forecasting
• Lifecycle planning
• Performance benchmarking
• Refurbishment scheduling
• Asset management support

OceanGrid combines practical field experience with independent technical expertise gained through battery commissioning, troubleshooting, system integration, and operational support across marine energy storage applications.

We understand the challenges faced by vessel owners because we have worked directly with operators, shipyards, system integrators, and battery manufacturers throughout the lifecycle of complex energy storage systems.

Our focus is not selling batteries.

Our focus is helping clients protect the batteries they already own.
