"SHIPMOOR" WHARF OR PIER SIDE MOORING ANALYSIS & DESIGN SOFTWARE
SHIPMOOR is an easy-to-use wharf or pierside mooring analysis computer program for use of port engineers and naval architects. It is based on the OCIMF and UFC recommendations, guidelines and procedures and includes OCIMF wind, current and wave drift coefficients for tanker moorings and gas carriers mooring. SHIPMOOR can be used in advance for planning of vessel’s mooring . it is very useful to optimize the mooring at the berth. |

At terminals, SHIPMOOR can be used to check the adequacy of terminal mooring equipment’s and to access if extra resources are required for adequate mooring. The need for and effectiveness of additional mooring lines can be decided. Otherwise Wind or current limitations can be decided for existing mooring setup. Tide tables, draft variations and trim variations can be fixed for future time step analysis in advance and then used to check mooring line tending adequacy.
Vessel crew can use SHIPMOOR for advance planning of mooring line arrangement and can check line tending requirements.
Vessel owners and operators can use SHIPMOOR to check the adequacy of vessel mooring equipment placement on new and existing vessels. It can help determine if vessels can be safely moored at various terminals, and if special limitations are necessary.
Vessel and terminal personnel can train on SHIPMOOR to learn proper techniques of arranging and tending mooring lines. Advantages and problems of various mooring arrangements can be demonstrated. The time-forward feature with tide, draft and trim changes will illustrate how to anticipate line tending and what is the best tending action.
Key Features
SHIPMOOR is a simple but extensive spreadsheet based programme, using the formulae recommended by OCIMF and UCF, which is very user friendly for crew and non-technical persons.
SHIPMOOR, describes vessel’s mooring arrangement and the placement of terminal mooring bollards locations are prepared on simple "spread sheets". The wind and current velocities and directions are then input to analyse planned mooring system, by using newton-raphson approximation method.
Lines that are loaded more than there safety limits are highlighted in red.
SHIPMOOR has provision for input of initial and final draft and trim conditions and times. It also has provision for tide tables and local correction factors and even for tidal currents. Line tending requirements can be checked in future arrangement. At different times it will show lines tension level and will notify if there is any possibility of tension limit excursion.
SHIPMOOR minimizes the need for the user to gather, calculate, and input other data, relating to wind and current forces and mooring line strengths and elasticities.
A data base of wind and current coefficients includes OCIMF ,API and UCF wind and current coefficients for load calculations. SHIPMOOR has the option of auto calculation of windage areas based on the vessel , present draft and trim. It then calculates the forces and moments applied by the specified wind and current. Other external forces also can be applied.
SHIPMOOR database has the breaking strength and load-extension characteristics of mooring lines. Data are provided for wire, aramid/HMPE, nylon double braid, nylon plaited and stranded, polyester, and polypropylene. Both new and used characteristics for the synthetic ropes are provided, based on TTI and OCIMF test data. Synthetic tails on the ends of mooring wires are also included.
SHIPMOOR actually considers non linear extension property of synthetic ropes used for tail line which increases the accuracy of calculation.
SHIPMOOR considers the actual length of Main mooring line and tail line in its calculation by getting the inputs of winch, choke and bollards on the pier side. It calculates effects of fairlead and bollard elevations relative to vessel and pier decks.
Winch break limits can be set as limit of pay out tension which will help to reduce the possibility of damage to winch.
