01. Project Overview
PROJECT 001 | MARINE ENGINEERING
Two LNG dual fuel vessels experienced recurring fuel system failures and operational reliability concerns, creating substantial technical and financial exposure for the shipowner.
Following the expiration of the original equipment warranty, a comprehensive technical investigation was undertaken to establish the underlying causes, assess manufacturer responsibility and develop a substantiated technical claim.
Through detailed engineering analysis, structured documentation and direct manufacturer negotiations, a corrective resolution was secured covering critical component replacements and fuel system upgrades across both vessels, with the associated costs funded by the manufacturer.
02. The Technical Challenge
The vessels were experiencing repeated failures of critical high pressure fuel pump components, resulting in unreliable dual fuel engine operation, recurring maintenance interventions and increased operational expenditure.
Previous replacement efforts had not delivered a permanent solution, while the continued recurrence of similar failures raised concerns regarding component integrity, system design and the effectiveness of the manufacturer's corrective measures.
The situation was further complicated by the expiration of the original equipment warranty, leaving the shipowner exposed to substantial repair and replacement costs without an established contractual basis for further warranty coverage.
The principal challenge was therefore not simply to restore equipment functionality, but to establish a technically defensible link between the recurring failures and their underlying cause, supporting a claim for manufacturer responsibility beyond the original warranty period.
03. Investigation & Root Cause Analysis
A comprehensive engineering investigation was initiated to establish the technical origin of the recurring high pressure fuel pump failures and determine whether the observed defects were attributable to operating conditions, maintenance practices or inherent equipment deficiencies.
The assessment focused on reviewing historical failure patterns, maintenance and replacement records, component performance, technical correspondence and the manufacturer's previous responses. Particular attention was given to identifying recurring characteristics across both vessels and evaluating the effectiveness of earlier interventions.
The findings were consolidated into a structured technical assessment, distinguishing the consequences of repeated component failures from the underlying engineering concerns. This provided the foundation for challenging the manufacturer's previous position and requesting a permanent corrective solution rather than further isolated component replacements.
The investigation formed the technical basis of a comprehensive claim, enabling the shipowner's position to be presented through documented engineering evidence, clear identification of technical responsibilities and a defined corrective action strategy.
04. Technical Claims & Manufacturer Negotiations
With the technical investigation completed, the findings were developed into a comprehensive engineering claim challenging the manufacturer's position regarding the recurring equipment failures.
The claim brought together documented failure history, supporting technical evidence, engineering assessments and a clearly defined corrective action proposal. Rather than pursuing compensation for individual failed components alone, the objective was to establish manufacturer accountability and secure a permanent technical resolution across both vessels.
Direct discussions and technical negotiations were conducted with the manufacturer, addressing the underlying equipment deficiencies, the recurrence of failures and the inadequacy of previous corrective interventions.
A particularly significant aspect of the negotiations was that the original warranty period had already expired. The technical evidence was therefore essential in establishing a credible basis for requesting manufacturer support beyond the contractual warranty arrangements.
The negotiations resulted in the manufacturer accepting responsibility for the identified deficiencies and agreeing to fund the corrective measures, including critical component replacements and fuel system upgrades for both vessels.
This outcome demonstrated the value of combining independent engineering judgment, structured technical claims management and commercially focused negotiations to protect the shipowner's interests.
05. Corrective Actions & System Upgrades
Following the technical investigation and successful manufacturer negotiations, a comprehensive corrective action programme was agreed for both vessels.
The proposed resolution went beyond the replacement of failed components. It addressed the wider fuel supply system, with the objective of eliminating recurring deficiencies, improving equipment reliability and reducing the risk of further operational disruption.
The corrective action program included:
Replacement of critical high pressure fuel pump components affected by recurring failures.
Technical modifications and upgrades to the associated fuel supply systems, addressing the deficiencies identified during the investigation.
Coordination of the manufacturer's corrective action requirements across both vessels to ensure a consistent technical solution.
Review of the proposed modifications and their intended effectiveness in preventing the recurrence of similar failures.
Establishment of a structured technical framework for implementing the agreed corrective measures and monitoring subsequent equipment performance.
A key achievement was securing the manufacturer's financial responsibility for the agreed component replacements and system upgrades, despite the expiration of the original warranty period.
The resulting programme provided the shipowner with a defined engineering solution while avoiding the financial burden of funding the agreed corrective measures independently.
06. Results & Client Value
The project delivered a significant technical and commercial outcome for the shipowner, transforming a recurring equipment reliability problem into a structured manufacturer-supported corrective programme.
Through comprehensive engineering investigation, substantiated technical claims and direct negotiations, manufacturer responsibility was established despite the expiration of the original equipment warranty.
Key Project Outcomes
Manufacturer Accountability
Secured recognition of manufacturer responsibility for the identified equipment deficiencies, establishing the basis for corrective action beyond the original warranty period.
Financial Protection
Obtained manufacturer funding for the agreed corrective measures, protecting the shipowner from bearing the associated component replacement and system upgrade costs.
Comprehensive Technical Resolution
Secured a corrective action programme covering critical fuel pump components and wider fuel system improvements across both vessels, rather than relying on repeated individual component replacements.
Fleetwide Consistency
Extended the agreed technical approach to both affected vessels, allowing the identified deficiencies to be addressed through a coordinated programme.
Operational Risk Reduction
Established a structured corrective strategy intended to improve machinery reliability, reduce recurring technical exposure and support more stable dual fuel operation.
The Value Delivered
The principal achievement was not simply obtaining manufacturer support after warranty expiration. It was the ability to connect engineering evidence with technical accountability and commercial negotiations, delivering a corrective solution that protected the shipowner's financial interests while addressing the underlying machinery concerns.
This project demonstrates how rigorous technical investigation and effective claims management can turn complex equipment failures into measurable commercial value.
07. Engineering Evidence. Commercial Results.
Complex machinery failures require more than technical repairs. They demand a clear understanding of the underlying causes, a defensible assessment of responsibility and the ability to translate engineering findings into effective commercial action.
This project reflects the technical investigation, claims management and negotiation experience now brought together through Seaworthy Dynamics.
From recurring equipment failures and disputed manufacturer responsibility to technically substantiated claims and corrective action strategies, our approach focuses on protecting shipowners' interests and delivering practical, commercially meaningful outcomes.
