The twin-screw trailing suction hopper dredger Apollo, recently delivered by Verolme Shipyard Heusden B.V. to J. P. Broekhoven of Zeist, is a sister ship, except as regards some machinery items, of the Poseidon, which was fully described in the article covered by Abstract No. 37,743 (Sept. 1974). The maximum dredging depth is 32 m, and the two suction tubes are 900 mm in diameter. The hopper, of 5,000-sq m capacity, can hold a maximum of 6,868 tons of spoil of relative density 1.5, equivalent to three weeks' continuous operation at sea. The dredger can operate in waves up to 6-m high. Propulsion is by two Bolnes type 18 V-DNL 150/600 Diesels, each developing 2,700 hp to 600 rpm and driving c.p. propellers. The combined pumping capacity of the two Vos dredge pumps is 9,900 sq m/h; each is driven by a Bolnes type 12V-DNL 150/600 engine developing 1,800 hp. The article, which includes general-arrangement drawings and a partial list of equipment suppliers, describes the dredging functions, dredging controls, hopper compartment, navigation equipment, engineroom, deck machinery, electrical installations, and accommodation. Order from: BSRA as No. 47,429.
