1.0 GENERAL

1.1 Introduction This report presents a full transport analysis on request of SPT Offshore b.v. for the EXAMPLE PROJECT Project. The report presents the used input data and a full report of the analysis. This report has been created online without any human interference. The client should carefully check the input and output before the results can be used. It is the sole responsibility of the client to assure that the results are correct.

1.2 Scope The scope of this report is to present the hydrostatic characteristics of this transport. The analysis includes: • Floatation analysis • Stability check according Noble Denton • Hydrodynamic motion analysis • Bollard-pull calculation • Barge Longitudinal Loading

1.3 Design Criteria This section presents the design criteria used for the transport.

1.3.1 Floating condition, - Static heel should be smaller than 0.5 degree. - Pitch should be between 0.0 to 0.2 degree aft down.

1.3.2 Stability requirements, The criteria as recommended by Noble Denton Association (NDA), ref. 1, will be followed. The following criteria will be checked for intact and damaged condition: 1. Intact Stability

• Minimum range of intact static stability: 36 Degree • Dynamic safety factor should be larger than 1.4

Alternatively, if maximum amplitudes of motion for the transport has been derived from motion response calculations, the intact range of stability shall be not less than;

(20 + 0.8θ) degree where θ = the maximum amplitude of roll or pitch caused by the design seastate, plus the static wind heel or trim caused by the design wind, in degrees. Furthermore the IMO intact stability requirements for pontoons, ref.2, need to be adhered to as well. • Area under the righting lever curve up to the angle of maximum righting lever should not be less

than 0.08 meter-radian ( = 4.58 m.degree) • The static angle of heel due to wind with speed 30 m/s (=58.4 knot) should not exceed and heel

angle corresponding to half the freeboard. For this transport the maximum wind heel should not exceed 7.2 Degree

• The minimum range of stability should be: • For L =< 100 m PRS>20 degree • For L= > 150 m PRS>15 degree • For intermediate length PRS by interpolation • For this pontoon minimum range = 20.0 Degree

2. Damaged Stability The transport will be checked for one compartment stability using the following criteria:

• Minimum range of damaged static stability: 15 Degree • Dynamic safety factor should be larger than 1.4

1.3.3 Environmental conditions Design Storm For a weather unrestricted tow, the design storm for the transport shall be the 10 year return period monthly extreme storm for the planned route, reduced as appropriate for exposure of less than 30 days. The transport can also be classed as a weather restricted operations which allows the design environmental conditions to be set independent of extreme statistical data. The analysed design storm together with the planned route, duration and season determine weather this transport should be classed as restricted or unrestricted. The following conditions have been used for this analysis: Design Seastate Seastate Hs = 6.0 m, 8.8 < Tp < 13.4 sec The Tp range follows the recommendation of the Noble Denton Guideline reference 1. , To represent the seastate a Jonswap spectrum with a peak shape factor of 3.3 will be used without spreading. The following 5 headings will be used: 0 Stern 45 Quartering stern SB 90 Beam SB 135 Quartering bow SB 180 Head on MOSES will use T01 to define the seastate spectrum. The relation Tp/T01 has been based on the recommendation from Torsethagen et all, reference 4. Design Wind Intact The 1 minute mean wind velocity at 10 m above sealevel for the design storm shall be used for the overturning moment calculations. In the absence of appropriate wind data the following wind data shall be used:

• Intact condition: 100 kn • Damaged condition 50 kn

For this analysis the following wind data have been used:

• Intact Condition: 40.0 kn (1 min mean velocity @ 10 m above sealevel) • Damaged Condition: 40.0 kn (1 min mean velocity @ 10 m above sealevel)

Wind profile has been based on ABS.

1.4 Bollard pull requirement Minimum towline pull required (TPR) will be computed for zero forward speed against the following conditions acting simultaneously: • 20 m/s (40 kn)wind

• Hs = 5.0 m seastate • 0.5 m/s current Minimum required static bollard pull of the tug(s) will be calculated as follows: BP = TPR / Te where Te = the tug efficiency factor. For this analysis a Te of 0.75 is used.

1.5 Design Velocity The design transport velocity will be 7 kn. This value will be used to estimate the tow resistance.

1.7 Barge Characteristic The following cargo barge have been used: Name = Barge AMT Discoverer Model name = amt_Disc Length = 91.7 m Width = 30 m Depth = 7.6 m Lightship = 2325.00 Ton with VCG at 4.40 m above keel

1.8 Barge Longitudinal Loading The barge longitudinal loading has been calculated considering the weight distribution of the barge, cargo and ballastwater and the loading due to a hogging and sagging wave.

The following wave has been used to calculate the longitudinal loading on the barge: Wave Length = 91.7 m Equal to the length of the barge Wave Height = 5.8 m Wave height has been based on the following empirical formula: 0.607*L^0.5 m

3.0 COMPUTER MODEL

3.1 General This chapter presents the description of the model that has been used for the hydrostatic analysis of the transport. For the marine analysis, MOSES from Ultramarine, has been used. MOSES is a multipurpose marine and structural simulation computer program widely used for transport and installation design of offshore structures. See the ultramarine internet website for more information on MOSES, address is: http://www.ultramarine.com/ The computer model used for this run has been developed by Online Marine Engineering and bears revision code M.1.5.A.1.14.. The definition of the co-ordinate system for the marine analysis is as follows: Origin at barge centre, keel level and centre line. X-axis : Positive from barge bow towards stern Y-axis : Positive towards Starboard side Z-axis : Positive is upwards See figure 3.1.

Figure 3.1 Definition of marine co-ordinate system

3.2 Description of the barge model To calculate stability a single body model is used. This model consists of one rigid body composed of several compartments with the following properties: Compartment Type Remark Barge Standard Strip theory model Barge Ballast Tanks

Standard All tanks have been modelled
