Salvage/Wreck Removal
TMC's own in-house software provides capability for, amongst other applications: emergency response, damage assessment calculations and container securing.
Our computer programs are written by experienced naval architects and benefit from TMC surveyors’ practical expertise combined with TMC naval architects academic knowledge and experience. This means that, should it be required for a casualty situation, each program may be tailored to suit a particular problem encountered, and this can be done at short notice.
Our software programs most regularly required to deal with a casualty situation, or subsequent technical investigation, are:
Seamaster
The SEAMASTER program is a naval architecture suite of programs for assessing longitudinal strength and intact/damage stability, and can also be used as a cargo loading program. This program is currently used as the basis for over 250 loading instruments installed on many vessel types, trading worldwide. It is approved by all the major classification societies including LRS, DNV, ABS, GL, BV, NKK and CCS. The program is normally used as a basis on which additional programs can be seamlessly added.
Seaflood
The SEAFLOOD program allows any compartment in the vessel to be flooded (including those which would normally be dry, e.g. engine room, cargo holds). Each space may be free flooded, or a hole of a specific size and position may be incorporated and the effect upon the vessel, over a specified period or time steps, can be seen. The program also allows for progressive flooding of adjacent compartments directly or via adjoining spaces (e.g. pipe ducts, other non-watertight areas), in order to investigate the effect on global strength and stability.
Seadam
The SEADAM program allows rapid assessment of the residual, longitudinal strength of a vessel following severe structural damage due to explosion, grounding, collision, etc. and subjected to applied loads. The software permits the analysis of structural strength after the total or partial failure of girders, longitudinal stiffeners, plating etc. SEADAM re-calculates the bending moments and shear forces, allowing for effects of applied loads such as cargo, flooding, sea loads and grounding reaction. The program has a functionality to include soundings taken around the vessel for calculating the grounding reaction force and also takes into account tidal effects. The effects of wave loading on the vessel can also be incorporated and allow for wave height, period and angle of incidence.
Comlash
With the COMLASH program, the forces and moments 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 vessel stability, draught and environmental conditions affect the forces generated.
