Marine fuel is a blended fuel, which has become the dominant energy source for deep-draught commercial vessels. Fuels used in marine applications are quite diverse in their properties. Low-viscosity distillate fuels and high -viscosity residual fuels can both be considered as marine fuels. The applications though, would differ and could include use in direct injected diesel engines, boilers and gas turbines. Also high speed, medium-speed and slow-speed engines can be found in marine applications. Fuels used in marine applications include marine gas oil, marine diesel oil, marine intermediate fuels and marine residual fuels and bunker fuel oil. The critical properties related to marine fuels include ash content, carbon residue, calculated carbon aromatically index, density, sulfur, total sediment and viscosity.

A marine gangway to enable handicapped users to move between floating and fixed landings may include a gangway ramp extending between the floating and fixed landings and at least one rail carried by the gangway ramp. The marine gangway may further include a drive unit coupled to at least one rail and movable between the floating and fixed landings and a handicapped user lift unit carried by the drive unit and pivoting with respect to the level at least one of the floating and fixed landings. As such the lift unit may remain level in a loading/unloading position at the floating or fixed landing despite changes in inclination of the gangway ramp, which prevents damage to the lift unit as a result thereof.

Marine Breakaway Couplings are specifically designed to be installed within a hose string where the coupling would have the length of the hose on both sides. Typical operations include ship to off shore platform and ship to ship product transfer. Available in ball, disc, or check valve styles. The coupling has additional external features that provide increased resistance to bending moments and trosional forces which may be exerted upon the coupling and therfore preventing premature activation.
