Horizon Shipbuilding has been awarded a contract under which it is to build up to four escort/rescue tugs for[ds_preview] McAllister Towing & Transportation. The hull of the first vessel, called »Capt. Brian A. McAllister«, has been flipped and set on the shipbuilding ways. Prior to the flip, a considerable amount of work was performed while the hull was upside down including installation of all major pipe runs and manifolds, fabrication and installation of cable trays and bulkhead penetrations and fender installation. Each tug will be 30,5m x 12m. The vessels built for escort and rescue operations are powered by a pair of Caterpillar 3516E Tier 4 engines with Schottel SRP4000 FP azimuth thrusters. The package will produce a total of 6,770hp and 80 metric tons of bollard pull. The hull design from Jensen Maritime is for enhanced shipdocking in addition to direct and indirect escorting.
