Our Official Performance Auditing offers quick and fair solutions, preventing costly disagreements and facilitating efficient communication to assist ship owners and charterers.
Auditing Support
At Weathernews, performance assessment is not limited to post-voyage analysis. We provide continuous insights throughout the voyage, combining real-time monitoring, objective weather analysis, and post-voyage evaluation to support fair, reliable, and legally sound vessel performance assessment.
During the voyage
After the voyage

In maritime charter party agreements, vessels are typically warranted to perform at specific speeds and consumption rates under good weather conditions. This warranty becomes effective when these favorable conditions are met.
Our auditing methodology aligns with English Case Law, which allows us to assess a vessel's performance in ideal weather conditions and then extrapolate this assessment to evaluate the vessel's overall voyage performance.
Under the common law system, decisions made by higher English courts establish principles that lower courts and arbitration tribunals are expected to apply. By aligning our methodology with English Case Law, Weathernews provides auditing support based on a consistent, objective, and legally sound approach.
At Weathernews, we recognize that vague charter party terminology often leads to disputes within the maritime industry. We have witnessed countless disagreements arising from ambiguous terms, particularly the inclusion of the Douglas Sea Scale in charter party agreements.
Drawing from our extensive experience in inspecting thousands of charter party agreements, we advocate for clearer terms to prevent disputes. To this end, we have proposed a Speed and Consumption Clause that defines good weather, performance measurements, and dispute resolution.
This clause, aligned with the Good Weather Method under English Case Law, offers objectivity, guidance in disputes, and adaptability for parties' needs.
We believe this approach can help significantly reduce disputes related to good weather interpretation, performance assessment, and voyage damage/savings calculations.
Claims Support
Performance disputes have the potential to cause tremendous strife between contracting parties, require many hours of discussion and negotiation between parties, and have led to significant legal costs over the years.
Drawing from extensive experience, Weathernews supports both ship owners and charterers in performance assessment and dispute resolution, helping them avoid costly disagreements through objective and reliable analysis.
Weathernews Voyage Audit Reports are developed independently of any party's position in a charter party agreement, supporting efficient discussions and fair settlements between contracting parties after a given voyage.
Live Insights
Ship owners are keenly interested in and aware of the performance of their vessels on a daily basis. Weathernews helps ship owners maintain a deep understanding of vessel performance across any given voyage.
Weathernews offers online platforms, mid-voyage reports, and live risk communicator assistance, enabling ship owners not only to monitor vessel performance after the fact, but also to identify and anticipate elements that may affect future performance.
Our services also help ship owners take proactive measures to ensure that vessels live up to their contractual obligations. Proactivity is a fundamental component of the services that Weathernews offers to the ship owning sector.


Quick Reporting
Organizations that charter vessels for their cargo-carrying capabilities face numerous tasks and challenges across any given voyage. Daily vessel operations require significant focus and time from operators, who must coordinate not only with the vessel and crew, but also with external parties such as port operators, fuel suppliers, and legal teams.
In addition to these responsibilities, vessel operators are tasked with monitoring a vessel's performance against the agreed charter party terms, while also keeping track of the vessel's estimated time of arrival.
Weathernews supports these tasks by monitoring vessel performance against charter party warranted terms. The same online and mid-voyage products offered to ship owners are also available to ship operators, helping them monitor vessel performance and anticipate upcoming conditions that may affect speed and/or consumption.
Furthermore, we ensure that charterers receive swift performance reports as soon as the vessel arrives, empowering them to make prompt decisions and proceed with post-voyage settlements efficiently.
Unbiased Reliability
By offering products that support both ship owners and charterers, Weathernews helps keep all parties informed and involved in performance monitoring. Transparency is key to minimizing disputes and supporting a safe, efficient, and charter party compliant voyage.
This objective approach allows Weathernews to offer multi-party nominations for the same voyage. Weathernews is well equipped to provide monitoring and communication services to both vessel owners and charterers on a single voyage.
With all parties monitoring vessel performance and watching the forecast along the projected route, transparency is maintained throughout the voyage, reducing the likelihood of unexpected discrepancies or disputes at the end of the voyage.
