An independent route and performance monitoring bureau, upon their nomination prepares a post voyage analysis either on charterers or owners behalf by making all efforts so as to arrive to an accurate result and to provide objective ship performance reports. Interoutes’ stance is to assess the performance of the vessels on voyages, in accordance with the High Court decisions and the latest Awards in Maritime Tribunals.

As it happens in a customary way, on vessels being monitored in real-time performance assessment, the Performance and Claims team has extensive experience in preparing the voyage reports, which are ready to be used in case of arbitration and legal proceedings.

The Performance Evaluation method is based on a Good Weather Analysis, a methodology for speed and bunker analysis calculations in good weather, as set out in three English Law precedents, namely:

- “The Didymi” case [1988]. 2 Lloyd's Rep 108 [Didymi Corporation vs. Atlantic Lines and Navigation Inc.]
- "The “Gas Enterprise” case [1993]. B.P. Shipping Ltd. vs. Exmar N.V. [The Gas Enterprise) -    Court of Appeal. LMLN 0357]
- “The Gaz Energy” case. [Hyundai Merchant Marine Company Limited v Trafigura Beheer BV vs Daelim Corporation (The “Gaz Energy”)  English Commercial Court: Flaux J: [2011] EWHC 3108 (Comm) 29 November 2011 and English Commercial Court: Teare J: [2012] EWHC 1686 (Comm): 21 June 2012]
 
 as well as on the following cases and awards in London Arbitration:
 
- London Arbitration 13/97. LMLN 465: 30 August 1997.
- LMLN 533. 2000 Linden Navigation Corp v Grand Eastern Co Ltd (The ‘Dimitris Perrotis’)

- London Arbitration 15/05. LMLN 670, 20 July 2005.

The final and completed post performance evaluation report is produced without prejudice to any party by taking into account the relevant charter party/fixture recap, voyage abstracts and daily noon reports, which are requested form the very beginning and made available together with other documentation.
