14. A method of well intervention comprising lowering a flexible hose into a well through a stuffing seal which engages around the hose during lowering, at least one tool being provided at a downhole end portion of the hose, and a plurality of individual tubes extending along an inside region of the hose and connecting to the at least one tool, each individual tube providing a fluid path for fluid communication between outside of the well and the at least one tool inside the well, and each individual tube being laterally supported in said inside region such that its lateral movement is restricted;
wherein the flexible hose includes a bottom hole assembly disposed at the downhole end portion of the hose, and the bottom hole assembly has a sealing arrangement that includes a seal disposed around the downhole end portion of the hose and a pair of wedge members, each wedge member extending a circumferential distance around the hose, wherein the sealing arrangement is configured so that the wedge members compress the seal into sealing engagement with the hose.
