The document discusses when boats are retired from service as the offshore support vessel market is experiencing a boom in newbuild construction. It notes that existing smaller and medium anchor handling tug supply vessels and platform supply vessels, totaling over 1,100 vessels, have an average age of 23 years. With around 50 new rigs on order and 206 new offshore support vessels also on order, it is estimated that around 105 older vessels will need to be retired to make way for the new ships. However, voluntary scrapping of older vessels is challenging due to low scrap prices of around $300 per lightweight tonne, which may not even cover mobilization costs. Alternative scrapping options discussed include selling machinery for reuse or grouping vessels together for scrapping
