As the days count down to the entry into force of the 2020 0.5% sulphur cap, preparation is key. DNV GL offers a free web-based application of the Ship Implementation Plan (SIP) that ship owners and managers can use to prepare vessel-specific SIPs and maintain an overview of their fleet. While not mandatory, the SIP is an IMO guidance which all ships are encouraged to prepare and implement to be ready for 1 January 2020.
