Marine scrubber application Classification of Marine Scrubbers On the basis of their operation, marine scrubbers can be classified into Wet and Dry scrubbers. Dry scrubbers employ solid lime as the alkaline scrubbing material which removes sulphur dioxide from exhaust gasses. Wet scrubbers use water which is sprayed into the exhaust gas for the same purpose. […]
Costs of scrubbers on ship What are the costs of scrubbers? Scrubbers are increasingly being fitted to newbuildings but the majority now in operation have been retrofits. The time for a retrofit is currently more than a typical scheduled drydocking meaning that extra lost earning days add to the capital outlay. The capital cost of […]
Scrubbers on ships really work Long before scrubbers or even before SOx was considered an issue for the shipping industry it was being regulated around the globe in connection with the use of large diesel engines in power production and other shore-based industries. As a consequence, exhaust gas cleaning or scrubbing technology is already a long […]
Open loop and closed loop scubber system for ship Classification of Marine Scrubbers On the basis of their operation, marine scrubbers can be classified into Wet and Dry scrubbers. Dry scrubbers employ solid lime as the alkaline scrubbing material which removes sulphur dioxide from exhaust gasses. Wet scrubbers use water which is sprayed into the […]
A guide to scrubber system on ship Scrubbers or Exhaust Gas Cleaning Systems (EGCS) are used to remove particulate matter and harmful components, such as sulphur oxides (SOx) and nitrogen oxides (NOx) from the exhaust gasses generated as a result of combustion processes in marine engines, to implement pollution control. These scrubbing systems have been developed and employed […]
Types of Modern Anti Vibration Components Used in Piping Installations There are two basic categories of anti-vibration components, these being in-line and hanging. 1. In-line Devices Bellows These consist of a set of accordion-like steel bellows that are designed and rated for different weights of piping. The bellows are encompassed between two flanges used to bolt […]
Ship Anchor Classification Anchor Classification There are Certification Authorities such as Lloyds, ABS, and DNV who class and certify anchors for use in naval and commercial ships. There are two classifications used; HHP (High Holding Power) and SHHP (Super High Holding Power) and these are noted on the relevant certification. There are also two basic […]
Bulk Oil Cargo The standard defence put forward by a shipowner to a cargo shortage claim used to be that the loss was below or equal to 0.5% of the total cargo. This figure, which originally stemmed from the cargo insurance deductible, was used by shipowners and cargo insurers as a yardstick for in-transit losses […]
Completion of Documentation For Bulk Oil Cargoes Completion of Documentation Once calculation of the ship’s figures has been completed, the shore installation will provide a shore figure. It is generally this figure that is used on the B/L. It is most unlikely that the two figures will precisely coincide, although in practice, and in the […]
Shortage and Contamination Claims For Bulk Oil Cargoes Claims arising from the carriage of oil cargoes are often substantial and may allege either shortage or contamination or both. This chapter provides guidance on how tanker operators can minimise the risk of cargo loss or damage and defend themselves should claims arise. Oil Shortages In general, […]
