    1 Introduction

    Introduction

    A seaport will be built near Port Ancient. A fictitious port at a fictitious location. The primary function

    of this port is the transhipment of containers. Moreover, the harbour will be accommodated with a

    LNG jetty, while area for dry bulk facilities will be reserved for future activity.

    The location is characterised by a few small islands, of which Rum Island is the closest as it is shown

    by following figure.

    Figure 1 New port location

    The purpose of this case study is to develop the layout of the port based on the available boundary

    conditions and the prognosis of the cargo throughput for the year 2015.

    2 Data and Boundary Conditions

    Data and Boundary Conditions

    All data are based on given study number that is 1357985.

    Throughput and Traffic Volumes

    The throughput and traffic volumes expected in 2015 are shown in the following table. It is assumed

    that a year consists of 8400 operational hours and required time for mooring is 2 hours.

    Determination the number of berths based on queuing theory.

    For Container transhipment

    Arrival rate () : 500 calls/year

    Service time : 2800/100 = 28 hours/ship

    Total service time : 28 + 2 = 30 hours/ship

    Service rate () : 8400/30

    = 280 ships/year

    Utilization () : /(*n) (n = number of berth)

    = 500/(280*n)

    From above calculation, number of berth for container terminal is 4 berths

    For LNG transhipment

    Arrival rate () : 80 calls/year

    Service time : 125.000/12.500 = 10 hours/ship

    Total service time : 10 + 2 = 12 hours/ship

    Service rate () : 8400/12

    = 700 ships/year

    Utilization () : /(*n) (n = number of berth)

    = 80/(700*n)

    From above calculation, number of berth for container terminal is 1 berth

    From chart E2/E2/n, it is obtained

    3 Data and Boundary Conditions

    For Dry bulk transhipment

    Arrival rate () : 275 calls/year

    Service time : 100.000/3.500 = 29 hours/ship

    Total service time : 29 + 2 = 31 hours/ship

    Service rate () : 8400/31

    = 271 ships/year

    Utilization () : /(*n) (n = number of berth)

    = 275/(271*n)

    From above calculation, number of berth for container terminal is 3 berths

    Design Vessels

    The cargo capacity of design vessels are given as follow. Based on PIANC report 121 2014, ship

    dimension can also be estimated.

    = (1.1 * 4 * (80% * 278 + 15)) + 15

    = 1059.56 m ~ 1100 m

    For LNG vessel

    Lq = Ls + 2*15 Ls = 80% LOA

    = (80% * 274) + 30

    = 249.2 m ~ 250 m

    For Dry bulk vessel

    Lq = (1.1 * n * (Ls + 15)) + 15 Ls = 80% LOA

    = (1.1 * 3 * (80% * 290 + 15)) + 15

    = 830.1 m ~ 840 m

    4 Data and Boundary Conditions

    Water Level

    Water level data are based on tidal data below.

    Table 2 Tidal data

    Currents

    Two normative current directions are north-east (NE) and south-west (SW). The maximum current

    velocity is 0.3 m/s. The data of current velocities for different water depths are shown below.

    Table 3 Current velocities

    Waves

    The dominant wave is 2.5 m which is situated around 140. This is also the maximum permitted for

    pilots boarding a vessel. The extreme wave condition has two dominant directions; west-south-west

    (WSW) and some less from east direction. Completely, the wave height exceedance and extreme

    frequency are given by table below.

    Table 4 Wave height exceedance and extreme condition

    The significant wave period is 12 s for the waves between 2,5 and 3,5. Moreover, long waves with

    small wave heights and periods between the 30 and maximum 80 s are registered.
