Feasibility study
During the feasibility study the impact of modifying the Skandi Sotra to a cable laying vessel was investigated. The deliverables consisted of a new design matching client requirement. During this process, multiple redesigns of the vessel’s deck layout were executed. The main goal was to achieve an optimized cable laying layout. The redesigned general arrangements considered: required deck space reservations, cable laying equipment and increasing the original accommodation to 56 berths.
Updating documentation
Besides a new general arrangement, structural related items impacted by the conversion were investigated. Items such as required number of bulkheads, bow height, location of collision bulkhead, equipment number, required freeboard, bending moments and shear forces are all verified and are after conversion still in accordance with class and flag state, respectively.
Stability impact
In addition to above mentioned scope an investigation of the impact on stability due to the conversion was executed. A preliminary lightship weight and a new deadweight were conducted. The converted vessel has a carrying capacity of 1500 km of cable (repeater and repeaterless) for the SA type. A total of 13 loading conditions were evaluated and all were found sufficient which ensures stability of the vessel after conversion.
After delivering the results of our feasibility study, the client is now ready to investigate their options regarding different conversion solutions matching their budget. A process of requesting offers for the conversion by different shipbuilders will be the next phase.
