Exhaust Economizers: A Silent Contributor to Green Technology
Next generation economizers are being introduced by Ulmatec Pyro. This will carry on the history of 35 years of heat recovery from ship’s exhaust – a technology that’s still unknown for many in the marine industry. You can’t ignore waste energy recovery systems if you want to participate in discussions about efficient marine designs. That statement is based on the fact that most diesel engines on board a vessel still operate on an efficiency scale in the 30 percent range. The remaining 60-70 percent represents losses, converted into heat.
Hyundai Samho Heavy Industries Delivers Green VLCC
Hyundai Samho Heavy Industries (HSHI) has completed building a scrubber-equipped Very Large Crude oil Carrier (VLCC), the first of two ships ordered by Greek shipowner Almi Tankers in August 2016, reported the Pulse. The affiliate with South Korea's largest shipbuilder Hyundai Heavy Industries (HHI) said that the VLCC is fitted with an exhaust gas cleaning system that can meet stricter restrictions on sulphur oxide emissions that will come into force in 2020. HSHI on Tuesday held a naming ceremony for the oil tanker. The 310,000-ton VLCC - which is 336 meters long, 60 meters wide, and 30 meters deep - is loaded with various facilities…

New Compact Genset Muffler
Equipment noise can quickly spoil the ambiance of even the most luxurious craft. Such problems are a thing of the past for lovely 130' Lady Kath, according to her captain, Bill Hipple. A new Marine Exhaust Systems G-19 water drop generator muffler significantly reduced genset exhaust noise, creating more peaceful days and nights for all onboard. After the installation, Lady Kath's 65 kW naturally aspirated Northern Lights generator exhaust was only 74 dBA. This allows normal tone conversation.
ClassNK Updates Scrubbers Guidelines
Classification society ClassNK said it has released the second version of its Guidelines for Exhaust Gas Cleaning Systems. Based on the first version Guidelines released in August 2014, the latest version includes the results of joint research and testing on actual Exhaust Gas Cleaning Systems. In an effort to reduce SOx and PM emissions from ships, MARPOL Annex VI limits the maximum allowable amount of sulphur contents of fuel oil used onboard globally, as well as place stricter requirements in geographically defined Emission Control Areas (ECA). Last October it was determined that stricter global sulphur limit of 0.5 percent is to be started on 1 January 2020.
New Diesel Soot Filtration System
Problems caused by inefficient regeneration of a Diesel Particulate Filter (DPF) can be eliminated with the installation of a SeaClean Soot Filtration System (shown above) by marine exhaust system engineering, design, fabrication and service company DeAngelo Marine Exhaust. The SeaClean system monitors the exhaust gas temperature and varies the power going to the heater element so that exhaust gas temperatures are constant. This allows a DPF to work properly so that collected soot is burnt off at high temperature, leaving only a tiny ash residue.

Wärtsilä Launches Inline Scrubber System
Wärtsilä said its new inline scrubber system is designed to offer notable benefits over conventional exhaust gas cleaning systems, and its compact form saves considerable space, which is particularly important in smaller vessels and when being retrofitted, while the lower cost structure of the new design offers CAPEX advantages. With just one scrubber system per engine, installation is faster and easier, Wärtsilä said, which consequently reduces the out-of-service time for the vessel. Operational flexibility is also improved.

ClassNK's Guidelines for Exhaust Gas Cleaning Systems
Leading classification society ClassNK announced that it has released Guidelines for Exhaust Gas Cleaning Systems. These guidelines cover class safety requirements as well as safety requirements stipulated in the IMO guidelines. The MARPOL Convention Annex VI has placed phased limits on the maximum allowable amount of sulphur in fuel oils used by vessels globally, as well as stricter requirements in geographically defined emission control areas. Under the regulation, more stringent limits will be enforced over time. In the face of these more stringent limits, the industry has begun to look towards alternative solutions to the expensive low sulphur content fuel oils currently required by the regulations.

DNV GL Approvals for SAACKE Scrubbers
Classification increases planning certainty for exhaust gas scrubber operators. The classification society DNV GL has certified the SAACKE exhaust gas scrubber based on soot separation using a dry process. This ensures that the innovative system, which was initially installed in 2013 on the tanker MT Levana, owned by the Carl Büttner shipping company, can now be operated without restriction. "Many scrubbers manufactured by market competitors currently operate with special permits. This means that the operator is exposed to the risk that the investment may not pay off.
