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.
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.
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.
Scope of work:
- General arrangement
- Reviewing delivered general arrangement
- Investigating different design solutions
- Updating/amended the general arrangement resulting in an improved layout
- Investigating impact of new design on relevant rules and regulations
- Cable carrying capacity
- Cable tank sizing
- Loading conditions
In an interview with Offshore Energy Magazine our CEO Sander Broekmeulen shares his vision on vessel conversions and its potential to be the ‘win-win’ our industry is looking for when it comes to costs and environmental impact. Read the full article here.
