Mooring analysis is an essential tool for vessel and Port operations personnel, especially when assessments are required to be undertaken to meet the requirements of governing bodies. The process helps Port and vessel operators understand how moored vessels behave in response to met-ocean conditions, so they can take the necessary precautionary measures. By helping to mitigate potentially harmful situations, the tool can help prevent downtime and ship breaks. Ultimately, this can make the difference between efficient, safe and profitable operations and costly, time-consuming ones. Equally important, Mooring Analysis can also help at the planning stage of a marine facility during optimisation.

Eka Infra’s expert onboard panel can accurately calculate and model the behaviour of moored vessels and provide valuable advice with regards to the type and number of mooring lines to be deployed during specific situations. Using this analysis, we can assist to optimise our clients’ marine facilities, which can help reduce costs, improve existing marine infrastructure and enhance cargo-handling efficiency. Our dedicated experts can help you with:

• Familiarisation and training of personnel

• Optimisation of Port layout

• Planning of mooring layouts

• Structural design of mooring facilities

• Analysis of moored vessel movements

• Calculating minimum safe passage distance

• Bollard and Fender selection

• Selection of Mooring lines

Eka Infra provides mooring analysis through OPTIMOOR software. This mooring analysis programme takes input data for a vessel and berth, and computes the mooring forces produced by defined wind, wave, current, and other forces as well as changes in draught and tide. The analysis allows several different moorings, environments, draught and tide situations to be quickly investigated so a vessel’s mooring arrangement can be planned accordingly. The software can be used for studying mooring of ships to a pier/jetty, ship-2-ship mooring, Turret and Single Point mooring and Solar Farms mooring to name a few.

The OPTIMOOR Dynamic version uses vessel hydrodynamic characteristics based on moving axes rather than earth-based axes, to perform a dynamic mooring analysis. With time-varying wind and current data input, the programme will calculate the corresponding time when varying forces are applied to the moored vessel and perform a dynamic analysis.

The OPTIMOOR Wave Response Module (previously called Seakeeping Option) uses special Hydrodynamic Coefficient data files (HCF) to calculate first-order wave induced vessel motions. Each HCF file comprises a set of 6 degrees of freedom hydrodynamic data, which were generated from the AQWA program. OPTIMOOR uses the HCF data to calculate the relevant response amplitude operators (RAO’s) for a water depth, vessel size, draft, trim, GM, and roll damping which are specified by the user.
