Blanking off Sea Chests

Blanking off Sea Chests

The Tanker Kit is well proven as a cost-saving alternative to dry-docking. It is used world-wide for blanking off sea chests.

Miko Plaster® – the main component of the Tanker Kit – is a magnetic tarpaulin that provides a temporary, but reliable, watertight seal below the waterline. It is qualified by DNV GL for blanking off sea chests, water inlets and outlets directly in the water. The seal is achieved by the water pressure and the magnetic adhesion between the patch and the steel surface.

No hot work or hydraulic tools are required for the installation. Supplementary tools required for installation are included in the kit. One Tanker Kit can be used for several sizes of sea chests.

Installation Principle

The drum is used for the storage and transportation of the Miko Plaster®, as well as for its installation. Both the drum and the larger patches are close to neutral buoyancy in water.

One MAM-001 Miko Anchor Magnet is placed outside each corner of the sea chest or opening to be patched.

The drum is lowered into the water from the deck by using the handling ropes, while the diver positions it correctly. With the two first corners secured to a MAM-001, the Miko Plaster® is rolled out from the drum to blank off the sea chest. The diver can easily re-position the patch if necessary.

The last two corners are secured to the other MAM-001 once the patch is completely rolled out in the correct position.

The MPM-002 Miko Permanent Magnets are placed on top of the patch to further increase the seal and to prevent it from being peeled off by any current.
