Purse seiners for China FISHING
T HE 180,000m2 area of the Fujian Southeast Shipyard is crowded with coastal freighters
in for repair and a series of modern anchor handling tugs in various stages of construction, writes Alan Haig-Brown. This ISO9001- certified yard has the capability of building ships to 10,000tonnes but also it has a long history of building fishing boats. At one of the fitting out docks, several 24m
tuna long liners await delivery to their French owners. At another dock, half a dozen purse seiners are rafted alongside each other. The purse seiners are part of a 36-boat
order from an owner on the island province of Hainan, located off China’s southeast coast. Each of the identical boats has a cabin aft with a long forward deck that includes the hold and forepeak, with a wide platform over which the seine can be set. While definitions of the actual fishing
method were somewhat limited by shipyard knowledge and technical translation it appears that the seine is pursed with a pair of capstans mounted on deck just under the wheelhouse. The seine would then be retrieved over the side and piled on deck ready to be reset over the bow. A skiff that will be suspended from davits
over the transom is used to aide in setting the net. Large banks of light sockets are mounted in rows to both port and starboard of the cabin for attracting the squid, which are the boat’s primary target.
A 36-boat order of 24m purse seiners is being built by Fujian Southeast Shipyard.
In the engineroom a Cummins NTA855
engine mounted port-side powers a 250kW generator to support the significant electrical demands of the banks of lights. Another Cummins NTA855 is mounted over the keel and turns a 1200mm propeller through a
300A Hangzhou Advance gearbox with 7:1 reduction. A third NT855 with slightly lower horsepower is mounted starboard side in the engineroom and turns an 800mm propeller through the same make and model of gearbox, but in this case with a 4:1 reduction.
Two fish farming workboats delivered T
OWARDS the end of last year, Grovfjord MekVerksted AS delivered the second of
two aluminium 8.85m salmon fish farming boats for Nordlaks AS, Norway. The boats, Toppsund and Øysund, are now used for the daily tending of salmon, and are equipped with a small crane and capstan winch. The fish farming workboats are operator-
friendly and rugged, and can be outfitted and equipped for a variety of uses. The hull provides a stable smooth ride with the ability to perform in the harshest conditions. Installed on both vessels was a single UltraJet
UJ305, driven by an Iveco NEF 370 330hp diesel engine at 2800rev/min via a ZF220

The boats have also been fitted with
Interceptor trim control units which work well even at the modest boat speeds.
