fires including Yantian Express, APL Vancouver, Grande America, E.R. Kobe and KMTC Hong Kong. The escalation is of growing concern and the International Union of Marine Insurance (IUMI) has called for an urgent improvement to onboard firefighting systems.


Be open to new cargo categories and new routes. The shape of global supply and demand is shifting, and shipping companies will need to be ready to adapt. Companies should make sure all routes and types of cargo are in the scope of research, including those with which they are not yet familiar. Companies that can get ahead of developing route or commodity trends may be able to pick up a considerable amount of new business. For example, China accounts for a large proportion of soybean imports, which it currently sources mostly from the United States and Brazil. In the future, however, the evolving global trading environment and domestic policy changes mean that emerging regions are likely to account for an increased portion of China’s soybean imports.

Get closer to customers. Customers are important sources of data and insight. Shipping companies that can cultivate strong customer relationships will have a better chance of understanding their future plans, and therefore of finding ways to serve them—both through core shipping and through value-added services (such as blending and transshipment).

, large floating device for underwater excavation. Dredging has four principal objectives: (1) to develop and maintain greater depths than naturally exist for canals, rivers, and harbours; (2) to obtain fill to raise the level of lowlands and thus create new land areas and improve drainage and sanitation; (3) to construct dams, dikes, and other control works for streams and seashore; and (4) to recover subaqueous deposits or marine life having commercial value.

Dredges are classed as mechanical and hydraulic. Many special types in both classes, and combinations of the two, have been devised. All types of dredges may have living quarters on board. Though dredges have been constructed to remove many kinds of deposits, the bulk of material removed has consisted of sand and mud.

, or clamshell, dredge lowers, closes, and raises a single bucket by means of flexible cables. In operation the bucket is dropped to the bottom, where it bites because of its weight and the action of the bucket-closing mechanism. A grab dredge can work at virtually unlimited depths. A ladder dredge employs a continuous chain of buckets rotating around a rigid adjustable frame called a ladder. When the ladder is lowered to the bottom at a slant, the empty buckets descend along the underside to the bottom, where they dig into the mud; the loaded buckets return along the ladder’s upper side and dump at the top. The scraper dredge, also called a dragline, handles material with a scoop suspended from a swinging boom. The scoop is drawn forward by a line attached to the front, while a second line attached to the rear holds the scoop at the proper angle to slice the earth away as the device is pulled along. A hydraulic dredge makes use of a centrifugal pump. In the pump casing, an impeller expels by centrifugal action a mixture of solids, water, and gases. As a partial vacuum is created within the pump, atmospheric pressure on the outside water surface and the weight of the water itself (hydrostatic pressure) both act to force water and suspended solids from the bottom through the suction pipe into the pump. The materials emerging from the pump are conveyed into barges or through another pipe to the shore. Long stakes, called spuds, are frequently used to pinion a dredge to the bottom.

Groin, in coastal engineering, a long, narrow structure built out into the water from a beach in order to prevent beach erosion or to trap and accumulate sand that would otherwise drift along the beach face and nearshore zone under the influence of waves approaching the beach at an angle. A groin can be successful in stabilizing a beach on the updrift side, but erosion tends to be aggravated on the downdrift side, which is deprived by the groin structure of replenishment by drifting sand. Partly to counteract this tendency, often multiple groins are built in so-called groin fields, which can stabilize a larger beach area. See also breakwater; jetty.

used sails and oars as propulsion methods. The introduction of steam-powered trawlers and the subsequent improvements in propulsion had a dramatic effect on the efficiency of fishing vessels, their spatial reach, and on landings; perhaps best documented in the Northern Atlantic (11). Whereas the focus nowadays is on industrial fishing operations, a vast portion of global fishing still occurs at artisanal levels (12, 13). Furthermore, as the research on fisheries is biased toward the developed world, the impact of the unpowered artisanal fishing fleet is often overlooked in academic studies. As up to a quarter of fishing vessels are unmotorized globally (1), neglecting this component of the fleet and its transition through technological advances results in vast underestimates of the impact of fishing, particularly, in the poorest parts of the world. Improved understanding of the motorization of the fishing fleet and taking a step back from focusing almost exclusively on detailed industrial fleets are fundamental for both reconstructing the past and for predicting the future evolution of fishing fleets. In this paper, we compiled data from various sources to fill in the gaps in the knowledge of global marine fishing fleets, particularly, their history and level of motorization, the separation to artisanal (both motorized and unmotorized, referred hereafter as “powered-artisanal” and “unpowered-artisanal”) and industrial sectors, and their fishing effort.
