Sediment Wastes from Ship Tanks and Waste Management of Shipyards

5th Eurasian Waste Management Symposium (EWMS) -- OCT 26-28, 2020 -- Istanbul, TURKEYSediment is the accumulation of sand and dirt that settles at the bottom of lake or the sea. Sediments are not only transported by water, but also the wind and glaciers. Beach sands and river channel deposits are examples of fluvial transport and deposition, though sediment also often settles out of slow-moving or standing water in lakes and oceans. Sediment's accumulation can cause some problems (i.e. cost increase in ship operation, tank corrosion, invasive species' transport) in ballast tanks. Ships should deliver dispose of sediments to shipyards and report in their annual or intermediate survey. The International Convention for the Control and Management of Ships' Ballast Water and Sediments (BWM Convention) was adopted in 2004 by consensus at a Diplomatic Conference organized at International Maritime Organization (IMO) Headquarters in London. And then, many guidelines were evolved to facilitate the implementation of BWM convention. For the control and management of ships' ballast water and sediments, BWM convention was split up into an annex and some articles including technical standards and requirements in the regulations. According to the convention, all shipyards must clean or repair ballast tanks, adequately built and safely operate, collect and dispose of sediments. In this study, authors investigate World and Turkish Shipyards which receive sediments from ships, prepare Sediment Management Plan for these shipyards and report about how many shipyards have completed responsibilities of the BWM convention.Yildiz Tech Univ, Environm Engn Dept,ISTAC Inc,Int Waste Working Grp,T C Cevre Sehircili Bakanligi,Turkish Airlines,Istanbul Convent & Visitors Bur,Cevre Norm,Artemis Aritim,Eced Cevre Danismanlik Muhendislik Hizmetleri San Ve Tic Ltd Sti,Ciftligim Gubre,MSB ARGE Cevre Enerji Teknolojileri Muh Egitim Dans Ltd Sti,Tin Muhendislik,Muhendislik Ar Ge Egitim & Danismanlik Ltd Sti,Aktan,GalaksiIstanbul Technical University Scientific Research Office (BAP) [MUA-2018-41105]This study was supported by the project (numbered as MUA-2018-41105 and titled as Turk Tersaneleri icin Sediman Atik Alim Tesisi Modeli Gelistirilmesi) funded by Istanbul Technical University Scientific Research Office (BAP)

Adaptation of port waste reception facilities to ballast water treatment system: Turkish port perspective

The introduction of invasive marine species into a new environment by ballast water attached to ship hulls has been identified as one of the four greatest threats to the world's oceans. Ballast water is water carried by ships to ensure stability, trim, and structural integrity. Shipping transports over 80% of the world's commodities, and each year transfers approximately 3 to 5 billion tons of ballast water internationally, which is, absolutely essential to the safe and efficient operation of modern shipping, providing balance and stability to unladen ships. However, it may also pose a serious ecological threat to the marine environment. The transferred species including bacteria, microbes, small invertebrates, eggs, cysts and larvae of various species may survive to establish a reproductive population in the host environment, becoming invasive, out-competing native species, and multiplying into pest proportions. Ballast water treatment is a technology for the treatment of ship ballast water from aquatic invasive species. Port waste reception facility should be modified to include ship ballast water treatment during this transitional phase until 2017. It provides onshore facilities in ports or terminals to transfer ballast water for cleaning or storage. This paper describes ballast water management, in general, and gives perspectives for the Turkish ports, and briefly suggests that the waste reception facilities must be modified for ballast water treatment

Prevention of invasive ventilation (PRiVENT)—a prospective, mixed-methods interventional, multicentre study with a parallel comparison group: study protocol

Abstract Background Invasive mechanical ventilation (IMV) is a standard therapy for intensive care patients with respiratory failure. With increasing population age and multimorbidity, the number of patients who cannot be weaned from IMV increases, resulting in impaired quality of life and high costs. In addition, human resources are tied up in the care of these patients. Methods The PRiVENT intervention is a prospective, mixed-methods interventional, multicentre study with a parallel comparison group selected from insurance claims data of the health insurer Allgemeine Ortskrankenkasse Baden-Württemberg (AOK-BW) conducted in Baden-Württemberg, Germany, over 24 months. Four weaning centres supervise 40 intensive care units (ICUs), that are responsible for patient recruitment. The primary outcome, successful weaning from IMV, will be evaluated using a mixed logistic regression model. Secondary outcomes will be evaluated using mixed regression models. Discussion The overall objective of the PRiVENT project is the evaluation of strategies to prevent long-term IMV. Additional objectives aim to improve weaning expertise in and cooperation with the adjacent Intensive Care Units. Trial registration This study is registered at ClinicalTrials.gov (NCT05260853). </jats:sec
