This article describes the various components and circuits used for large hatchways on vessels with restricted stowage distance between hatch and coamings. Earlier multi-folding hydraulic hatch covers incorporated internal actuators involving hydraulic piping within the hatch opening. Special cargoes such as newsprint or chemicals were vulnerable to damage from oil leaks. The main feature of the new system is the use of external hydraulic components and piping.
