With all equipment, maintenance is required. With all equipment there is a limited lifespan. Vessels are no different. There comes a point that replacement is the answer. Cost to keep a aging vessel in service is not the only factor. New technology in ships design allows a company to offer the latest in safety and lower operating costs. Along with planned maintenance there should be a planned replacement program. At ten years a vessel should be changed out. The results are twofold. New vessels require less maintenance. New vessels suffer less breakdowns.The vessel being replaced will command top dollar on the used boat market.

Don't agree with all that ,sorry
Limited Lifespan ..compared to aircraft ,trains, tugboats and other vessel's..these vessels are midlife..the space shuttles were older with more mileage..
New technology?.. these newer Stena liners don't even sport Azipods..twin variable screw coupled to Man diesels..nothing new there...the bulbous bow goes back as far as Yamato and the Japanese empire..55-60 year old technology.. Yes the newer Ro-Ro super's have ice breaking capability that allows the bulb to ride under busting the ice under its own weight ..of which the Smallwood and Caribou are in league ..the Finnjet also sported this when she was built in 1977..nothing new there in ice breaking capability..
The hulls are an existing design that goes back decades with tweaks to allow for draft,breath,length,HP,and tonnage..nothing new..
Other companies around the would continually flip vessels in/our commission the next latest and greatest, but then when a half dozen companies are in a pee'n contest for foot and lane traffic ..with the high volume of transport...the money is there to re-coup this and it make's sense to get rid of a vessel after 10 years just to keep up with the next guy..Which is how we got the Ericson ..beat half to death .been run aground...and we got her cheap ...and paid almost as much as another Caribou to fix her up ...Companies over in Euro ..dont get rid of a vessel thats making them money ,regardless of age ..they get rid of them because they are junk ..
