The performance of six of the ships fitted with the TM 410 medium speed engines attaining a significant number of running hours by 31st July, 1974 is tabulated. Details of the investigation into the nine exhaust valve failures that occurred early in the life of the m.v. Cape Grenville are given, together with the cause and its elimination. Performance of the re-engined ships has been re-assessed against the advantages envisaged in 1968, when the decision to use medium speed engines for bulkcarrier propulsion was taken. The results of a design study carried out in 1974, using figures taken from low speed and medium speed engines at sea, operating in similar ships and under the same management company are also mentioned. These results confirm that the most attractive installation for a bulkcarrier of about 26,000 dwt is one using twin medium speed diesels geared to a single propeller.
