A cladding (10) for an elongate member to be deployed underwater includes multiple cladding sections (12, 26) each being configured to receive the elongate member and each having proximal and distal ends configured to engage with longitudinally neighbouring cladding sections (12, 26) enabling a continuous length of the cladding to be constructed from multiple cladding sections. At least one of the cladding sections is provided with a sensor module dock (28) configured to receive and releasably mount a sensor module (30) to the cladding.

An instrument hose support device includes a rod that supports an instrument hose at a position higher than an instrument that is held by a holder, a pulley support portion that is supported by a distal end of the rod, a pulley that is supported by the pulley support portion and over which the instrument hose is looped. The distal end has a groove in which a taper is formed. A first member of the pulley support portion has a shaft protrusion, and a gap is formed between the shaft protrusion and the groove. The gap serves as the range of motion of the pulley support portion, and the pulley support portion follows the movement of the instrument hose and, relative to the rod, swings freely toward the front and the back and toward the sides and rotates freely with a movable axis (X) as an axis.

The invention concerns a line guide device (100 . . . 1100) for lines like for example cables, hoses or the like, in particular for a clean room application, which has a flexible sheath (210 . . . 610). The sheath (210 . . . 1100) is designed in the manner of a corrugated tube and has a corrugated profile for the purposes of flexibility. The sheath (210 . . . 1100) has an asymmetric bending characteristic in relation to curvature about the direction-changing axis and to opposite curvature such that the permitted bending sag is considerably less than the desired curvature.

According to an aspect there is proposed a particular configuration of shell portions (331, 332; 1031, 1032; 1201, 1202) for constructing the sheath, in particular in respect of the corrugated profiles and the fixing of the shell portions (1201, 1202).

A further aspect concerns a supporting skeleton (440; 540; 640; 940) for a corrugated tube.
