Introduction
Purpose of Project Purpose of Project Assess and possibly implement the leasing of a new vessel in the leasing of a new vessel in 2012 to replace the existing icebreaking research vessel icebreaking research vessel NATHANIEL B. PALMER
National Science Foundation (NSF) • Is an independent U.S. Government agency Is an independent U S Government agency • Invests over $5.6 billion each year in about 20 000 research and education projects in 20,000 research and education projects in science and engineering • One of the programs is the United States • One of the programs is the United States Antarctic Program
NSF’s S s Office of Polar Programs • Supports basic research in a wide range of scientific disciplines in both the Arctic and scientific disciplines in both the Arctic and Antarctic • Additionally, provides logistics, operational and Additionally, provides logistics, operational and laboratory support both shore side and in the marine environment • Current marine activities in the Antarctic are provided by two vessels: – NATHANIEL B. PALMER NATHANIEL B PALMER – LAURENCE M. GOULD
NATHANIEL B. PALMER - 1992 to present
LAURENCE M. GOULD - 1997 to present
U.S. Antarctic Research Vessel HERO - 1968 to 1984
U S Department of Transportation U.S. Department of Transportation Maritime Administration (MARAD) • Memorandum of Agreement between NSF g and MARAD • MARAD to provide technical support MARAD to provide technical support including naval architecture and marine engineering services, technical g g , management, acquisition support, construction oversight and acceptance tests and trials for the new vessel
Initial Requirements l New Vessel for V N
Science Requirements • Bottom mapping during icebreaking • Geotechnical drilling capability • Geotechnical drilling capability • Enhanced towing of nets and instruments in ice • Moon pool (completely enclosed) to deploy – Autonomous Underwater Vehicle (AUV)/Remotely Operated Vehicle (ROV) – Diving – Conductivity, Temperature, Depth (CTD) rosette – Ocean-Bottom Seismograph (OBS) • Accommodation for 50 scientists Accommodation for 50 scientists • Provision for a helicopter deck and hangar • Traditional set of A-frames, winches, cranes • Inter-deck science/cargo elevator Inter deck science/cargo elevator
Operational Requirements p q • Enhanced level icebreaking @ 3 knots -- 1.4m • Capable of independent operation in multiyear ice p p p y • Suitable for operations in both polar regions • Excellent seakeeping capability • Endurance at 12 knots -- 80 days/20,000 miles • Endurance at 12 knots -- 80 days/20 000 miles • Comply with new International Maritime Organization (IMO) Guidelines for Arctic Vessels [effectively a double h ll hull vessel] l] • Improve ship’s self-generated noise signature for better scientific acoustic sensor performance • Reduce exhaust emissions from diesel engines and incinerator • Clear view aft from starboard pilot house control station Clear view aft from starboard pilot house control station

Podded Propulsion System Currently Preferred • Direct drive diesels are hard • Direct drive diesels are hard to fit into a ship with a large moon pool – electric plant provides flexibility provides flexibility • Diesel generators can be “floated” on isolation mounts for low noise/vibration • Twin azimuthal propulsors give greater maneuverability in ice and open water station in ice and open water station keeping

To achieve the 2007 goal -- there is a g need to reduce the quantity of sulfur in diesel fuel oil in diesel fuel oil. Sulfur inhibits the use of NO x and particulate matter emission reduction particulate matter emission reduction equipment (such as catalysts and filters) which are needed to meet filters) which are needed to meet U.S. Environmental Protection A Agency regulations for air quality. l ti f i lit
