CNG and Low Emissions

Seaphantom will be able to use CNG in most countries of the world. Of all the fossil fuels, CNG is the cleanest mass produced fuel.

seaphantom’s cng option

The CNG fuel option for our Phantom fleet is an option probably soon wisely explored, especially given the likelihood of CNG being readily available on offshore oil rigs for our offshore operators. With CNG widely available in the United States, SPI would base its fuel supply on greener, cleaner fuel that would not be vulnerable to Mid East and other crude oil disruptions.

Manufacturers produce kits for almost all gasoline and diesel engines and are widely available for around $2,500 (plus installation by certified mechanics locally available).

Adding another $7,500 (per engine) for special fuel tanks and “marinization” brings the cost to an estimated $12,500 per vessel. These systems are designed for simple selector switch control to quickly change back to the engine’s original fuel. Finally, we would estimate that there would be an infrastructure cost of $85,000 for small scale land based high-pressure pumps and tanks.
