Software for loading, stability, stress
WSLP2TM is a 3D Windows loading program written in Visual C++ by Ocean Motions.
- cargo planning and ballast control
- real-time tank level and draft inputs
- intact, damaged, grounded
- finds remedial solutions to refloat or bring upright
Quick Calc™
- instantaneous draft, trim, heel, KG and GM margins, max stress, torsion, deflections as you edit
3D on-the-fly
- drafts, trim, heel, KG, GM, GZ, downflooding, ground reaction, stresses, deflections….
WSLP2™ reports
- Loading detail and summaries
- Cargo manifests
- Drafts when intact, drafts throughout flooding, drafts at damage equilibrium, grounded drafts
- Comparison of computed to observed/sensed drafts
- Righting arm curves, tables, dynamic stability
- Shear force, bending moment, torsion and deflection distributions
- Primary stress distributions, intact and after structural damage
- Gyradii
WSLP2™ advantages:
- graphical
- draw, drag and drop new loads
- attitude graphics show vessel trimmed and heeled
Auto COG
- LCG, TCG, VCG, FSMT, FSML computed as tank levels, trim & heel change
Riser
- tension and riser side force
Moorings
- layout, tensions, moments, catenary, suction piles
Thrusters
- forces and moments, deployed and retracted
Winds
- heel for any wind direction and strength
Waves
- stability and strength in waves
Crane Lifts
- animated graphic as crane and hook load move
- instant stability and stress update
- instant comparison to maximum allowed KG or GM min
- monitoring in real-time when connected to sensors
- pick up and move a load on deck
- pick up a load from another vessel
- pick up a subsea load
- place load elsewhere
- warning of SWL exceedence
- simulate response to dropped hook load
Damage
- Graphical when you don’t know where the damage has occured, user draws openings to the sea using the mouse
- Check Box when you do know which tanks and spaces are damaged, select from the list of tanks, voids, spaces
- various stages of inflow/outflow through openings to the sea
- equilibrium drafts, trim, heel after all inflow/outflow has ceased
- downflood openings, vents automatically detected
- damaged GMT, damaged GML, damaged righting arms about any axis of inclination
- comparison to damage stability criteria MODU, HSE, IMO, USCG, MARPOL….
Ballast Advice
- program automatically computes how much to load in user specified tanks
Auto Draft
- user specifies target draft, program automatically figures out how best to achieve that draft
Auto Trim
- user specifies required trim, program automatically relocates loads to achieve this trim
Auto Heel
- user specifies required heel, program automatically loads ballast to achieve this heel
Auto Margin
- user specifies desired GM or KG margin, program keeps loading til this margin is achieved
Export
- to management and financial software, onboard and to shore sites
E-mail
- daily stability reports all in one concise SL2 file
Links
- bi-directional comms to your tank gauging, MetOcean consoles, instruments, sensors
Protocols
- COMMS_2000 | OPC | CSV | CLINO-PAK | Kongsberg | SAAB | GE Modbus………
Units
- Metric or Imperial, and can be mixed
References
- longitudinal references from a selected Frame, midships, AP or FP
Conventions
- TCGs can be positive to port or positive to starboard
LWT Trak™
- track growth in lightweight at sea
- track new location of lightweight LCG, VCG, TCG
- requires connection to the proprietary sensor, the Ocean Motions CLINO-PAK
