1.0 GENERAL

1.1 Introduction This report presents a full transport analysis on request of SPT Offshore b.v. for the EXAMPLE PROJECT Demo run for reviewProject. The report presents the used input data and a full report of the analysis.

This box can be used to enter your project specific text in the introduction of the report.

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 Bollard-pull calculation

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 International (NDI), 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

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 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. For this transport the following conditions has been used:

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

The wave drift forces will not be calculated for this analysis. An estimate will be used based on the following empirical formula: Fwave = 1.5 x Barge Width (Ton).

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.

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

ratio of 1.40 can be met.

4.3.2 IMO Criteria

The hydrostatic analysis revealed that all intact stability requirements as set IMO ref. 2, have been met.

The following checks have been performed:

Range of Stability The range of intact static stability for the transport is 58.00 degree. The minimum required range of stability is: 20.00 degree


Stability Curve Area Check Area under the righting lever curve up to the angle of maximum righting lever is 86.06 m.Degree. The minimum required Area is: 4.58 m.Degree

It can be concluded that the Area under the righting lever curve is adequate for this transport.

Wind Heel check The intact wind heel for the transport is 0.34 degree. The maximum allowed wind heel is: 7.22 degree

It can be concluded that the wind heel criterion is met for this transport.

4.4 Damaged Stability Check

4.4.1 Range of Stability The range of damaged static stability for the transport is 58.00 degree.

The minimum required range of stability is: 15 degree


4.4.2 Wind overturning check The found area ratio for the damaged condition is 56.49, which shows that the minimum requirement area ratio of 1.4 can be met.

4.5 Barge Longitudinal Loading

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

The following Stillwater loadings have been found: Maximum bending moment = 2.75099E4 Ton.m Minimum bending moment = -102.6 Ton.m Maximum Shear loading = 1151.2 Ton Minimum Shear loading = -993.0 Ton

The following governing loadings have been found for the Hogging and Sagging load condition:

Maximum bending moment = 6.54409E4 Ton.m Maximum Shear loading = 2171.0 Ton

A detailed report and plots of the longitudinal loading calculations can be found in the MOSES output included in attachment 1.

4.7 Bollard Pull analysis Minimum towline pull required (TPR) has been 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

The wave drift forces have not be calculated for this analysis. An estimate has been used based on the following empirical formula:

Fwave = 0.5 x Barge Width x Barge Draft = 57.0 Ton

Found Minimum towline pull including estimated wave drift force is:

TPR = 84.7 Ton

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.

BP = 84.7/ 0.75 = 112.9 Ton

For the design speed of 7.0 kn, the drag at transport draft is: 73.6 Ton.

The Froude number at this speed is FR = v/(g.L)^0.5 = 0.12 . For Froude numbers large than 0.11 wave resistance will start to dominate and should be added to the above reported drag resistance to find the total resistance during tow at the design speed.
