Abstract
A technique which enables construction and operation of a subsea landing string system having a system manifold or manifolds unprotected by a dielectric fluid compensated enclosure. The manifolds contain directional control valves and corresponding solenoids which are able to operate while being exposed to environmental fluids such as seawater. The ability to operate manifolds in an unprotected environment enables the manifolds to be positioned in a variety of locations along the subsea landing string system or in cooperation with the subsea landing string system. The subsea landing string system also may be a modular system in which manifolds are added or removed according to the parameters of a given operation.
