The California Air Resources Board (CARB) has implemented several regulations to reduce emissions from both oceangoing vessels and harbor craft, and they’re not about fuels of the future; they’re about the here and now. The regulations in California, which have begun to phase-in, may ultimately impose standards even tighter than the EPA’s Tier 4.

Against the considerable hoopla surrounding new fuels, and demon- stration projects, internal combustion engines are alive and well. In the inter- national deepsea realm, methanol fuel- ing for conventional engines has been gaining traction, notably with orders for large containerships by giants like

Maersk and CMA CGM. Methanol may soon ? gure into larger vessels in the Jones Act landscape; Overseas Shi- pholding Group (OSG) recently an- nounced the purchase of the laid-up tanker Alaskan Frontier, which will see extensive engine refurbishments including “[preparing] the engines for possible methanol fuel in the future.”
