The design of work Boat have become very important in the world especially in the Niger Delta region of Nigeria, now that oil exploration is moving gradually from the onshore to the offshore. Hence the stability of the vessel at sea becomes critical for the safety of life and properties onboard the work boat. The design of a 2500 Tonnes offshore work boat, determination of optimal scantling for good stability characteristics, estimation of principal dimension and the analysis of the stability of the work boat in an offshore working condition was carried out. The stability characteristics of a rectangular work boat of dimension 42m x 7.5m x 5m were determined and analyzed using International codes and standards. The hydrostatic curves for the boat were plotted and used to determine the optimal values for safe operation of the work Boat. Furthermore the analysis of the stability of the entire work boat was done to ascertain the maximum load the vessel could carry not to exceed a safe value this shows the design is worth will. This was also verified using an inclining experiment model.
