Our computer software programs for, amongst other applications, damage response and container lashing calculations are state of the art.
They are written by experienced Naval Architects and benefit from TMC's on-site surveying expertise. This means that, should the casualty situation require it, each program may be altered at very short notice to cope with a particular problem encountered.
The four software programs which are most regularly required to deal with a casualty situation or subsequent casualty analysis are:
The SEAMASTER program is a basic longitudinal strength, intact stability and cargo loading program. It is used as the basis for over 250 loading instruments installed onboard all types of vessels trading worldwide.Seamaster programs have been approved for ships classed with LR, DnV, BV, ABS, NKK and GL and is usually used as a basis on which additional programs can be seamlessly added.
The SEAFLOOD program allows any compartment in the vessel to be flooded (including those which would normally be dry, for example the engine room, cargo spaces etc.). Each space may be free flooded, or a hole of a specific size and position may be entered and the effect on the vessel over a period of time can be seen. In addition to this, the program allows the progressive flooding of adjacent compartments through pipe ducts and other non-watertight areas, so that the effects on the vessel's strength and stability can be analysed.
The SEADAM program allows rapid assessment of the residual longitudinal strength of a vessel following explosion aboard, grounding, collision or some such other accident which leaves the vessel structurally damaged. The software permits the analysis of longitudinal strength of the vessel after the total or partial failure of girders, frames, plating etc. SEADAM allows for the recalculation of bending moments and sheer forces, allowing for the effect of grounding. There is a facility to use soundings taken around the vessel to calculate the reaction force taking into account the rise and fall of the tide. The effects of wave loading on the vessel may also be seen, dependant on the height, period, direction and phase of the waves.
With the COMLASH program, the forces generated in any stack of containers can be calculated to see if the safe working loads of the lashing gear or of the container frame itself have been exceeded. The calculations can be carried out to all the major Classification Society rules, and investigations can be undertaken to see how various factors such as the weather conditions, the vessel's GM/draught etc. would affect the forces generated.
TMC have now supplied software to over 250 vessels trading worldwide of all types from container ships, bulk carriers and tankers through to more specialised vessels such as copper concentrate silo vessels and semi submersibles.
Added to this are over 400 programs supplied by TMC which have been used in various capacities such as on site for salvage operations, for container stow collapse/losses investigations, for investigations into alleged scuttling and various other litigation work.
