Appts has two catamaran hull joined by a bridge. There is a plant for preparatory treatment of incoming gas on the bridge. The final treatment plant is mounted on at least one hull.

A heat pump has an evaporator connected to an output air heat exchanger, while its condenser transmits heat to a water usage circulation circuit which contains at least one main hot water accumulator. A separate heat exchanger is fitted between the condenser and the accumulators, in which heat from the heat pump work medium on the hot side is transmitted to incoming cold tap water and from which t...

The holder mechanism (7) bridges over the hole mouth, and is retained fixed in that position by fixtures (11) in contact with the uppermost well ring inner wall. The holder part in turn retains the actual manhole cover (2) with the aid of at least one upwardly directed part (6) which passes through a hole in the cover. A hang lock (12) prevents the cover being lifted away by unauthorised persons.

The container has an extraction opening (2) disposed in an end wall containing a door. The container can be set down so that the wall rests on a receiving vessel. To allow automatic extraction from the container, the door has a locking mechanism (13,14) operated from outside by a component (17) on the receiving vessel when the container is set down onto the vessel.
