JOPETWIL 250 Liftboat – Intact and Damage Stability Analysis

Description:
– Preparation of the trim and stability booklet for JOPETWIL 250 following replacement of the spudcans on its three legs with cookie-cutter spudcans.
– Development of the vessel hydrostatic model, tanks and watertight spaces in Bentley MOSES.
– Intact and damage stability assessments covering collision damage and individual compartment flooding.
– Calculation of allowable vertical centre-of-gravity (KG) limits across a range of drafts and heel axes.
– Windage-area and wind-heeling calculations incorporating hull, superstructure, legs, crane and helideck contributions, together with downflooding-point modelling.
– Evaluation of lightship, fully loaded departure and arrival conditions for ocean tow against the specified ABS and IMO MODU stability criteria.
– Revision of calculations and documentation in response to ABS review comments.
