Container ships Hatch covers Lashing bridges The best container stowage solutions are built around their intended cargo An efficient container stowage solution can only be achieved by treating the ship’s hull and its cargo handling system as a single optimised entity. Consequently, parts of the container stowage system, such as the hatch covers, lashing bridges, container stanchions, loose and fixed container fittings on deck and in the holds, and the cell guide system in the cargo holds, should be considered from an overall container stowage solution point of view, not as separate products....

The design criteria for a feeder vessel’s container stowage solution differ completely from the criteria for an ultra large container carrier, and so do their container securing systems. Whatever the size of the vessel, MacGregor knows how to design and deliver an efficient cargo handling and stowage system for containerised cargo. MacGregor knows how to get all the parts of a cargo handling system to work in unison, ensuring that a vessel sails with the best possible performance. Building a new container vessel is a major investment and the decisions taken at the early design phase will define...

Container ships Lift-away Hatch Covers The purpose of lift-away hatch covers on container ships is to carry deck cargo, split the container stack between hold and deck and to prevent excessive water ingress into the cargo hold. Depending on a container ship’s width, one to five panels cover each hold opening. The weight of an individual panel can be up to 45 tonnes. Lift-away panels are handled with a spreader using either shore-side container cranes or a vessel’s own cranes. The panels can be stacked together on the quay and/or on the ship’s de

Hatch cover technical details Sealing solutions Lift-away hatch covers can be either weathertight or non-tight. Non-tight panels are permitted for use on large container ships, while the hatch covers on smaller ships need to be weathertight. Weathertightness between hatch covers and coaming is generally achieved by a sliding seal, which is fitted to the panels and tightens against the top of the coaming. Sliding seals can be fitted to the panel joints, enabling both sequential and non-sequential operation. In the case of non-weathertight hatches, a labyrinth-type gasketless seal and/or an open...

According to class regulations, hold-down cleats can be omitted in some cases (IACS regulation 14). Quick-acting cleats Quick-acting cleats are actuated from above or below...

Photo: Hapag-Lloyd Guides and stoppers Optimised guiding and stopper arrangements are essential for the proper operation of lift-away covers. Initially, the panels are guided into position by the guides, with final guidance designed into the stoppers. The stoppers are located to provide minimum relative movements between the coaming and hatch covers. For stacking hatch covers, stack marks are provided on the covers. Fixed container fittings Fixed container fittings comprise the container foundations, lashing plates and lifting foundations for the container spreader. Special fittings Lift-away...
