Marine Propulsion HAL to Study Seawater Scrubber Technology While cruise ships are a relatively miniscule percentage of the world fleet of ships, these high-value, high-profile floating resorts are under arguably the highest scrutiny by environmentalists and legislators regarding air emissions. Cruise ships often sail into some of the world's most pristine aquatic sanctuaries, making meaning that adherence to high environmental standards are analogous with business success. To determine the feasibility of new technology designed to reduce air emissions on seagoing vessels, Holland America Line (HAL) plans on conducting a seawater scrubber feasibility project aboard one of its cruise ships thanks to the assistance of a $300,000 EPA/West Coast Collaborative grant and $100,000 contribution from Puget Sound Clean Air Agency. The total cost of the installation is more than $1.2m. The project is intended to demonstrate how advanced seawater scrubbing reduces air emissions on large oceangoing vessels. The results will determine whether this technology could be rolled out to new oceangoing vessels, as well as retrofitting existing vessels. "Holland America Line has always had a vigorous environmental program and we believe in being proactive on environmental issues," said Stein Kruse, president and CEO. "A scrubber has never previously been installed on a vessel engine of this size." "EPA is proud to be joining the Puget Sound Clean Air Agency, Environment Canada and others in supporting Holland America Line's demonstration of this innovative emissions reducing technology," said Michelle Pirzadeh, Acting Deputy Regional Administrator for USEPA's Region 10. "This effort joining Holland America Line with other members of our West Coast Collaborative shows once again the power of public/private partnerships in supporting a healthy environment and a vibrant economy." Partners in the project include Puget Sound Clean Air Agency, Environment Canada, Port of Seattle, Port of Vancouver and Caterpillar. Caterpillar will support the project with research about the impact of scrubber technology on engine performance, reliability and service life. The current plan is to install the scrubber on the ms Zaandam in Spring 2007. Following installation, the effectiveness of the scrubber will be analyzed and a final report submitted by June 2008. HAL will work with Puget Sound Clean Air Agency, who will be responsible for providing EPA funding and matching funds as a sub-recipient of the EPA grant award, as well as providing reports to the EPA and funding partners. This technology is expected to partially reduce nitrogen oxides (NOx), almost entirely eliminate sulfur dioxide (SOx) and significantly reduce particulate matter (PM). Heavy fuel oil is pretreated to reduce the NOx and PM formed during combustion. The engine emission enters the scrubber and the reaction between the SOx in the emission and the calcium carbonate (CaCO3) in seawater reduces the SOx in the smoke to almost zero. Largest Mobile Oil Drilling Unit Under Construction MPF Corp. Ltd. has ordered a MultiPurpose Floater - the MPF 100 offshore drilling vessel, which is being touted as the largest mobile oil drilling unit in the world, when completed. Wärtsilä won the contract to deliver a total power system the MPF 1000, which is planned to be completed and delivered from Dragados Offshore SA, Spain in the fourth quarter of 2008. The contract for Wärtsilä involves detail design, products, systems and commissioning of the power plant, propulsion, electrical and automation systems. "To deliver a total integration of power plant, power distribution, automation and propulsion systems for one of the first vessels that combines drilling and FPSO capabilities, our systems will ensure maximum performance, environmental friendliness and optimal lifecycle benefits both for the owner and the operator," said Magnus Miemois, Vice President of Wärtsilä Ship Power Solutions business. "Wärtsilä has over time been committed to MPF Corp. during various project stages with an influential and convincing understanding of our needs, and we are happy to conclude with Wärtsilä as one of the main sub-contractors for our Multi-Purpose Floater" said Tore Nedregaard, President and COO of MPF Corp. Wärtsilä will deliver eight 16-cylinder Wärtsilä 32 diesel engines with a com48 1000 can combine floating production, storage and offloading with drilling. It is designed for simultaneous drilling and production in deep waters and harsh environments including ultra deep water. The vessel is 951 ft. (290 m) long and has storage capability of one million barrels of oil. Gas Fueled Engines for Coastal Ferries Wärtsilä will deliver a total power system for the Multi-Purpose Floater, the MPF 1000, which is reportedly the largest mobile drilling unit ever built. bined power output of 58,880 kW, generators, medium voltage switchgear, low voltage distribution boards, frequency converters, safety and automation systems (including emergency shut down, fire and gas, power management, vessel automation), a DP3 dynamic positioning system, thruster control and information management systems. Wärtsilä's own frequency converter technology became part of Wärtsilä's product portfolio in conjunction with the acquisition of Wärtsilä Automation Norway. The systems will mainly be delivered as complete, fully-equipped factory-tested modules. The MPF 1000 is being touted as the largest and most versatile offshore drilling unit ever built. The vessel gives the oil companies a new tool in the exploration and development phases of offshore oil and gas fields. The MPF The first ship sets of Bergen gas engine powered generator sets have been delivered for ferries fueled by liquefied natural gas (LNG). The KVGS-12G4 gensets form part of the order for power plant for a series of five double-ended ferries which will provide vital links in the main road system on the west coast of Norway. The choice of LNG as fuel for these ferries was driven by two main considerations: reducing exhaust emissions of CO2 and NOx and creating a base load demand for LNG around which a broader local land gas distribution network can be built up. Five vessels are under construction: three will operate on the Halhjem/Sandvikvåg route connection south of Bergen and these will be powered for a 21-knot service speed; two will operate on the Arsvåg/Mortavika route north of Stavanger where a 17knot service speed is needed. In developing the new vessels the designer, LMG Marin, has worked closely with the operator, Fjord1. The design challenge was to combine a high service speed with a double-ended hull design which also has to fit the standard Norwegian Road Administration shore vehicle ramps. They are the first series production LNG fuelled passenger vessels in the world and they will also break new ground in passenger vessels by having the gas engines below the main deck. In addition to designing the vessels, LMG Marin also carried out the risk analysis with a special focus on gas hazards in passenger vessels. The conclusion is that the safety levels on board will be equal to or even higher than those of traditional diesel powered ferries operating on the Norwegian coast at present. The three faster vessels will each have a total of 12,370 kW of engine power provided by two 16-cylinder Bergen gas engines and two 12-cylinder units. The other two ferries have a much lower power requirement, which will be met by two of the KVGS-12G4 units each producing 2,650 kW. Maritime Reporter & Engineering News
