Fresh Water Volume Calculation
Papua New Guinea water usage = 64.3 m3/person/year Engine Power (kW): 1000
Source: http://www.fao.org/nr/water/aquastat/countries_regions/PNG/Tables.htm 200
Ship Construction and Design says 170 litres/person/day
Source: Ship Design and Construction, page 11‐26
Upper bound of fresh water consumption for passenger ships = 82.125 m3/person/year
Source: Marine Auxilliary Machinery by H D McGeorge, page 93
→ Assume 73 m3/person/year = 200 litres/person/day (to match with Lloyds Black + Grey water)
Specifications dictate freshwater supplies for 1000 nm; assume 14 knot speed
→ Assume speed of 14 knots
Total travel time = 71.42 hours
Total fresh water volume = 200 litres/person/day x 215 persons x 3 days / 1 m3/1000 l = 129 m3
→ Assume a reverse osmosis unit has been installed which is in use for 12 hours per day.
Required freshwater production rate = 200 l/person/day x 1 day/12 h x 1 h/60 minx 215 p = 60 l/min = 16 gal/min
Choose : Vantage® M41‐006 Reverse Osmosis Systems ‐‐> rated at 7.5 gal/min ‐‐> produces 61.24 m3 over 1000 NM
Dimensions: 0.826 x 0.87 x 1.867; Weight: 245 kg
http://www.water.siemens.com/en/products/membrane_filtration_separation/reverse_osmosis_systems_ro/Pages/vantage‐m41‐ro.aspx
→ Required fresh water tank volume = 129m3 ‐ 61m3 = 68 m3
Sewage Retention Tank with Aeration Calculation
Black water flow rates for passenger ships range around 15 litres/person/day. (Assuming vaccuum flushing)
Grey water flow rates for passenger ships range from 184 litres/person/day. (175+((85+40)*15(Crew)/215 (Total)))
Source: Lloyd's Part 2, Chapter 7, 2.10
→ Assuming use of a Biological Sewage Treatment System ‐ Sludge storage is required.
Liquid wastes are treated and recirculated for toilet and urinal flushing.
Solid waste holding tank capacity is close to 2 litres/person/day.
Source: Marine Auxilliary Machinery by H D McGeorge, page 108
Total sludge retention tank storage = 2 litres/person/day x 215 persons x 3 days / 1000 l/m3 = 1.3 m3
Total black+grey water flow rates = 184 litres/person/day x 215 persons = 39,500 litres/day
→ Choosing model ST25‐C by Wartsila Hamworthy.
Dimensions: 4.62 x 3.22 x 2.50
Weight = 27,830 kg
→ Sewage tank calculation:
Assuming sewage treatment system is broken
for longest trip between ports + 25% extra:
Sewage Tank Size = 200 l/person/day x 215 people x 1.25=
V = 54 m3

Lube Oil Calculations
Lube oil values for medium speed diesels can be approximated at 20 t
Source: Ship Design and Construction, page 11‐26
Typical lube oil consumption for medium speed diesel = 1.0 g/kWh
Assuming 1 1,500 kW engine, lube oil required for 1 trip
= 1.0 g/kWh x 1500 kW x 144 hours/trip x 1 kg/1000 g x 1 m3/890 kg = 0.25 m3
V= m3
Sludge Tank Calculations
Regulation 17(1) of MARPOL states:
V = K*C*D where V = sludge tank volume (m3)
K = 0.005
C = 7200 (daily fuel oil consumption ‐ metric tons)
D = 3 (maximum period of voyage between ports where sludge can be disposed; we need design for 1000 nm)
→ V = 200 g/kWh x 24 h x 1500 kW x 1 ton/1000000 g x 1 m3/1 ton
.
V = m3
Bilge Water Holding Tanks
Source: http://www.imo.org/blast/blastDataHelper.asp?data_id=14478&filename=511.pdf
→ V = 1.5 + (P‐1000)/1500
V = m3
Hot Water Tank
Crew Showers Stalls= 8
Passenger Shower Stalls = 20
Showerhead flow rate = 2.5 gpm or 10 L/min
Say 10 minutes per shower; 10 crew showers per day & 80 passenger showers per day
→ 100 L/shower x 90 showers/day x 10% margin = 10 m3
→ V = 2.5 m3 based on an educated guess

Comparison of Righting Arm Curve obtained manually to Paramarine results
Manual Derivation of Righting Arm Curve (with Displacement Held Constant)
[Heel Angles of 0, 5, 10, 20, 30, ... 80°]
The righting lever curve of a two-dimensional trimaran section was calculated and
compared with that of a similar hullform at the same draft obtained using Paramarine.
The derivation of the manual curve as well as the curves themselves may be found below.
Paramarine Hullform Model
The integrals of the righting arm curves
seen above are approximately 6%
different in magnitude, with the
Paramarine curve providing a more
conservative value for the same
conditions. It can be concluded that the
Paramarine stability software adequately
accounts for the complex hullform of a
trimaran. Paramarine will thus be used
with confidence for stability evaluation
throughout this report.

As seen, the vessel passes SOLAS 90 two-compartment damage criteria. A probabilistic method should be used on further design iterations to verify these results.

The table below details the performance of Damage Case 1 with the following load conditions
Arrival with passenger overcrowding + asymmetric cargo Arrival with passenger overcrowding + passengers assembled at one side
As seen, the vessel still passes SOLAS 90 two-compartment damage criteria under these extreme conditions. The passengers assembled at one side scenario is unlikely as the passengers must be dispersed throughout the vessel to accommodate the high level of overcrowding. Such a passenger-induced heeling moment is likely impossible.
The table below details the performance of outrigger damage with the following load conditions
Arrival with passenger overcrowding The cases analyzed represent the worst survivable damage that the side hull may take. The righting arm curves for these cases as well as their hydrostatics are detailed in the figure and table at right, respectively.
