![]() ![]() Prior to commencing such work, a temporary guide frame should be built as shown in the construction method for solid breakwaters. Overstuffed bags, item B, should not be incorporated into the wall. The jute bags should be filled with just enough concrete to form a pillow of uniform thickness, item A in Figure 1. The major advantage of this type of construction is that an uneven sea bed or large boulders can be included in the foundation as shown in the front elevation in Figure 1. This structure does not require any major cranage and may be built with the sole assistance of one or two divers. The earth-retaining structure, as the quay wall is known, consists of a number of layers of concrete-filled jute bags placed on a rubble foundation in a brickwall fashion. ![]() Table 1 Draft requirements Draft at low tide Vessels metres Large canoes to small purse seiners Maximum loaded draft 1 metre 3.0 metres Trawlers and other coastal vessels Maximum loaded draft 2.5 metres 6.0 metres Ocean-going distant water trawlers Maximum loaded draft Solid quays minimum draft 1.5 metres Figure 1 illustrates one of the best ways to construct an artisanal quay with a draft of 1 to 1.5 metres. An artisanal fishing port hosting small fishing vessels having a loaded draft of no more than 1 metre would not normally require a draft of more than 1.5 metres at low tide unless large vessels visit the port during the peak fishing season. A key element inside a typical fishing harbour, however, is the draft, ranging from 1.5 metres to 6 metres may be required, depending on the type, size and number of resident fishing vessels (Table 1). The objective being that the reader will be able to appreciate the different applications of past and more recent technologies and be better prepared to assess the potential requirements for berthing and boat maintenance structures.Ģ 108 Fishing harbour planning construction and management Contents 8.1 Quays Solid quays minimum draft 1.5 metres Solid quays minimum draft 3 metres Solid quays minimum draft 6 metres and beyond Open quays minimum draft 1.5 metres Open quays minimum draft 3 metres and beyond Jetties Jetties any draft Floating jetties Slipways Traditional slipways Slipways on beaches Mechanical slipways all sizes Vessel repair facilities Bibliography and further reading 132ģ Quays and slipways QUAYS The construction of quays falls broadly into two classifications: quays with a closed or solid construction, and quays with an open construction, where the deck is supported on piles. This chapter reviews the cross-sections of a wide variety of quays and jetties to suit an even wider range of applications. On the other hand, inside fishing harbours, the recent technological advances in boat hoists has further widened the range of options available to a would-be designer of slipways. However, a beach is not always suitable or available for servicing a vessel, especially vessels larger than small canoes. The traditional slipway in many small beach-side communities is still the natural beach where boats are hauled ashore for scrubbing, cleaning and repair. ![]() In areas with a high tidal range, both quays and jetties are often of the floating type. In contrast to a normal quay, a finger jetty may be used on both sides. A pier or finger jetty is a quay that projects into the water. It is generally contiguous with the shore. Make long-term plans and enjoy your glory when they come true, and this last connection will force six planets to renew at the same time.1 Quays and slipways SUMMARY For the purpose of this chapter, a quay is a general term used to describe a marine structure for the mooring or tying-up of vessels, and for loading and unloading of goods and passengers. Align everything correctly and watch your planets evolve and grow, giving you even more opportunities for profitable trade. Colonize the planets, carefully select industries and connect everything so that the products of one planet serve the needs of another planet.
