Renewable Energy Project

Posted to Marine Propulsion Report (by Keith Henderson) on October 16, 2010

Lloyd's Register is collaborating on a project to create a fleet of commercial coasters powered by a combination of sails and marine engine using biogas as a fuel. The project was instigated by B9 Shipping, based in Northern Ireland. part of the B9 Energy Group.

First HAM for Norwegian fishing industry

Posted to Marine Propulsion Report (by Keith Henderson) on October 3, 2010

For more than 10 years the Viking cruise ferry MV Mariella has been successfully operating her four S.E.M.T. Pielstick 12VPC2.6.diesel engines with Humid Air Motor . This year the, Norwegian owned, purse seiner/trawler and factory vessel MV Kvannøy built in 2002…

LNG storage tanks on ships

Posted to Marine Propulsion Report (by Keith Henderson) on October 3, 2010

The widening of the exhaust control and sulfur emission control areas in European and American  waters requires new solutions to enable vessels to comply with these requirements. Although use of MDO as a fuel is one way towards compliance, another possible and less expensive alternative is LNG.

Wärtsilä 3C Communication and Control Center

Posted to Marine Propulsion Report (by Keith Henderson) on September 25, 2010

Wärtsilä unveiled it’s new fully integrated vessel control system earlier this month at the SMM exhibition in Hamburg, Germany. The Wärtsliä Communication and Control Center (Wärtsilä 3C), connects all the separate systems used on board a vessel…

First Container Ship with Auxiliary LNG Power

Posted to Marine Propulsion Report (by Keith Henderson) on September 24, 2010

Announced during the recent SMM exhibition in Hamburg, the third generation German family container fleet owner Reederei Stefan Patjens is to retrofit a 5,000 TEU container vessel, the MV Maersk Drury for LNG operation. The 5,000 TEU container ship was built in 2006 by Hyundai Heavy Ind.…

Reducing Engine Noise

Posted to Marine Propulsion Report (by Keith Henderson) on September 19, 2010

At this year's CIMAC conference Wärtsilä presented a paper following a five year research program on noise reduction of medium speed engines. The test engine used was a seven cylinder 32 series engine of  3.5MW at 750 rpm with 320 mm bore and stroke of 400 mm.

Plug-in Shore Power

Posted to Marine Propulsion Report (by Keith Henderson) on September 18, 2010

A major factor slowing down the more widespread use of plug-in shore power to permit cold ironing is the lack of a safe, troublesome and easy to use standard for the shore to ship connector. Further complicating the problem is the abundance…

Hydrogen Power

Posted to Marine Propulsion Report (by Keith Henderson) on September 18, 2010

Cruising round the narrow canals of Amsterdam on a hot, airless, summer day sometimes involved passing through an exhaust cloud as the hundreds of boaters toured the sights. In a bold attempt to cut down exhaust emissions to zero, a new canal…

Black Magic for Green Vessels

Posted to Marine Propulsion Report (by Keith Henderson) on September 5, 2010

Following on from the design of his hybrid mega yacht Transcendence, Richard Sauter the founder of Sauter Zero Carbon Design, is showing a way forward for commercial ships of the future featuring a design for a zero carbon vessel with greatly reduced emissions of greenhouse gases (GHG).

Automatic Engine Tuning

Posted to Marine Propulsion Report (by Keith Henderson) on August 27, 2010

Automatic optimization of marine diesel engine performance using loop control of the cylinder pressure process has been under development for a number of years at both MAN Diesel & Turbo and Wärtsilä. Targeting the slow speed two stroke engines…

Royal Caribbean Stewardship

Posted to Marine Propulsion Report (by Keith Henderson) on August 26, 2010

The recently issued annual “Stewardship Report” from Royal Caribbean Cruises Ltd includes some detail of its efforts and successes in implementing efficiencies across its fleet of 38 cruise ships. Already achieving an average fuel consumption reduction of 4 per cent in 2008…

Detonation Gun Engine

Posted to Marine Propulsion Report (by Keith Henderson) on August 25, 2010

Any engineer will tell you that detonation in an engine is a bad thing and should be avoided otherwise destruction of the engine is a question of time. That’s because abnormal combustion, actually explosion, is taking place inside the combustion…

Ultrasonic Anti fouling

Posted to Marine Propulsion Report (by Keith Henderson) on August 23, 2010

The UK Ministry of Defence recently announced that they are going to use ultrasonic anti fouling technology to help maintain the performance of three of its LCVP landing craft. Each craft is to be fitted with three transducers, protecting not just their hulls but also the stern gear.

Wind Engine

Posted to Marine Propulsion Report (by Keith Henderson) on August 22, 2010

In an earlier blog Reducing Air Drag, I was talking about a wind related project by the UK based shipping environmental charity called Greenwave. They have another project using wind power that is reaching the final development stage and also…

Reducing Air Drag

Posted to Marine Propulsion Report (by Keith Henderson) on August 22, 2010

Since 2008, there is a UK based shipping environmental charity called Greenwave that strives to develop policies that not only encourage but reward ship owners for the early adoption of technologies designed to reduce emissions. Greenwave’s…

Mechanical Energy Storage

Posted to Marine Propulsion Report (by Keith Henderson) on August 17, 2010

The international combustion and engineering consultants Ricardo has been actively involved for a number of years in development of hybrid propulsion systems, including mechanical and electrical energy storage, and fuel cell systems for a number…

Exhaust Gas Scrubbers

Posted to Marine Propulsion Report (by Keith Henderson) on August 16, 2010

The expansion of Emission Control Areas (ECA) in North American and European waters leaves ship owners using HFO with little choice other than to use a more expensive low sulfur HFO, change to MDO completely or use a dual fuel arrangement. The…

Why do people make mistakes?

Posted to Marine Propulsion Report (by Keith Henderson) on August 4, 2010

Mistakes cause accidents. That is the inevitable sequence of events and we humans are the people making the mistakes, but why? What are the reasons that people make mistakes? Following on from my earlier blog on accidents and NK’s guidelines how to prevent them…
