Norway's Boa Offshore is reactivating two laid-up anchor-handlers for a government charter.

It said the Norwegian Defence Logistic Organisation (FLO) will use the 285-bp Boa Bison (built 2014) and 267-bp Boa Jarl (built 2015) for emergency response preparedness from 1 January.

The bareboat deals last five years, with five years of renewal options.
