LNG/Water Maritime Tanker Composite Rocket Fuel Tank Derived Moss tank

December 25, 2014

LNG/Water Maritime tanker Composite Rocket Fuel Tank derived Moss tank

Hypothesis; (A)The Maritime LNG and water trade could benefit from advances   in both Methane rocket propulsion launch vehicles and composite tanks and possibly the launch vehicles industry might learn from the maritime LNG water transport trade.(B) The launch industry can learn from accident and safety studies by the LNG maritime trade in t case of arbitrarily large Methane Powered extended launch vehicles( ALMPELV’s)

In the case NASA/Air force launch sites environmental impact studies for large Methane powered launch vehicles might be minimal but new commercial sites environmental impact studies might very well be informed by the DOE LNG safety research report to congress in 2012 at the bottom of this page.

 

 

Options,

several very large composite maritime Moss tanks

  • Poor fit in ship’s hull – ball in a box. Horizontal end caps from composite rocket tank design?
  • High windage on ships – slow speed manoeuvrability difficult. Horizontal end caps from composite rocket tank design?
  • Tank temperatures must be carefully controlled (equatorial tank temperature must be < -119C for loading).
  • Cool-down rate usually about –6C per hour.Cool down for composite rocket tank?
  • Wall thickness varies between 28-32mm at Poles and 160mm at equatorial ring. For a composite tank?
  • Tank weight about 800 tonnes.Weight for  composite rocket tank is half of this?
  • Superstructure has to be high to see over tanks – airdraft becomes limiting factor at some ports.
  • Horizontal end caps from composite rocket tank design? With many smaller 5 to 10 Meter tanks RO RO; commonly with launch vehicle propellant tanks?

LIQUEFIED NATURAL GAS SAFETY RESEARCH

 

LNG Cargo Tank Breach and Spill Analyses

 

LNG Cargo Capacity 140,000 m3 260,000 m3. Much larger than SLS or Methane powered SpaceX or ULA vehicles

 

Table 2. LNG Cargo Tank Breach Sizes Considered
Type Breach Area Breach Dimension
Very Small 0.005 m2 (0.25 ft x 0.25 ft)
Small 0.5 m2 (2.3 ft x 2.3 ft)
Medium 2-3 m2 (5.0 ft x 5.0 ft)
Large 5 m2 (7.3 ft x 7.3 ft)
Very Large 15 m2 (12.7 ft x 12.7 ft)

 

Large LNG Pool Fire Experimental Results

• Determining the Surface Emissive Power (SEP) of large LNG pool fires;
• Determining the fuel vaporization rate of LNG fires on water; and
• Determining the flame height to diameter ratios for large LNG pool fires.

$65 Billion gas pipeline is a great deal of money but amortized over 60 to 70 years, A LNG trade with San Diego with ships built-in san Diego is a much smaller investment but more expensive per unit delivered,does it benefit san Diego water rate payers to do  so?
