Applying science to pressing conservation needs for penguins

first_imgMore than half of the world’s 18 penguin species are declining. We, the Steering Committee of the International Union for Conservation of Nature Species Survival Commission Penguin Specialist Group, determined that the penguin species in most critical need of conservation action are African penguin (Spheniscus demersus), Galápagos penguin (Spheniscus mendiculus), and Yellow‐eyed penguin (Megadyptes antipodes). Due to small or rapidly declining populations, these species require immediate scientific collaboration and policy intervention. We also used a pairwise‐ranking approach to prioritize research and conservation needs for all penguins. Among the 12 cross‐taxa research areas we identified, we ranked quantifying population trends, estimating demographic rates, forecasting environmental patterns of change, and improving the knowledge of fisheries interactions as the highest priorities. The highest ranked conservation needs were to enhance marine spatial planning, improve stakeholder engagement, and develop disaster‐management and species‐specific action plans. We concurred that, to improve the translation of science into effective conservation for penguins, the scientific community and funding bodies must recognize the importance of and support long‐term research; research on and conservation of penguins must expand its focus to include the nonbreeding season and juvenile stage; marine reserves must be designed at ecologically appropriate spatial and temporal scales; and communication between scientists and decision makers must be improved with the help of individual scientists and interdisciplinary working groups.last_img read more

Damen DOP150 Dredge Pump for New Power Plant Project in Brazil

first_imgImage source: DamenDamen has supplied a DOP150 submersible dredge pump to Brazilian civil engineering contractor BELOV. It is now in operation, creating an access channel into the sea for a new power plant currently under construction, the Dutch defense, shipbuilding and engineering conglomerate said. The access channel is for a critical pipeline for the plant’s cooling system and when completed it will extend 600 meters out into the sea. Over the course of the project the DOP150 is expected to remove around 30,000 cubic meters of material.The Damen DOP150 is being used to extract sand in the surf zone, varying in density from loose to medium fine.“Working in such a dynamic marine environment presents challenges when it comes to delivering the flat, even surface required for the pipeline. Cables and other obstructions in the area also need to be worked around. The dredge pump is mounted on the boom of a 30-tonne excavator, itself mounted on tracks running along a pier. Concrete walls are being added to the access channel as the work proceeds to protect the piping,” Damen said.Image source: DamenThis particular model of Damen submersible dredge pump was selected due both to its ability to run off the excavator’s hydraulic power plant and the ease and speed with which the sand mining head can be exchanged for the cutter unit when the density of the material requires it to be broken up. An additional factor is its low assembly weight.The Porto de Sergipe I power plant is a 1,516 MW combined cycle, natural gas-fired design located in the state of Sergipe in the north-east of Brazil.A floating storage and regasification unit (FSRU) positioned 6.5 kilometers offshore will receive the LNG from tankers and supply gas to the plant via a submarine pipeline. Due to begin operations in January 2020, it will be the largest gas-fired power plant in the region.The DOP150 is the smallest in Damen’s range of submersible dredge pumps with an hourly capacity of 600 cubic meters of mixture. The DOP150 was delivered with both a jet water-assisted sand production head to be used in free-flowing sand, and a cutter unit to be used in compacted sand.The exchange between the heads can be done swiftly due to the practical identical mounting flange, said Damen.The six-model range extends up to the DOP 450L, which can move 4,000 cubic meters an hour via a 450mm pipe.Image source: Damenlast_img read more
