The certification allows Whitchampion to perform onboard blending of biofuels with petroleum distillates and residual fuel oils. The operation is authorised within UK coastal waters under a Tri-Partite Agreement between the Isle of Man Flag and the UK Maritime and Coastguard Agency (UKMCA).
A second Whitaker tanker, Whitchallenger, will be undergoing a similar approval process and is expected to be certified later this year.
At present, bunker tankers certified under MARPOL Annex I are limited to carrying blends no more than 30% FAME under IMO regulations. Oil Fuels with higher bio-content fall under International Bulk Chemical Code (IBC Code) and MARPOL Annex II, typically requiring full chemical tanker status. That regulation has, in effect, frozen out a significant portion of the conventional bunker tanker fleet from supporting mid-to-high-range biofuel blending.
