An arrangement for laying non-rigid product offshore that includes a dual long grip length clamp arrangement installed vertically into a tower in a similar manner to a J-lay trolley / clamp system. The invention differs from a J-lay arrangement in that two clamps are used and the clamps are configured for use with non-rigid product, i.e. they have a long grip length in order to spread the load evenly. Each clamp is mounted on a trolley and can travel vertically up or down. The upper clamp is arranged with a distance between it and the lower clamp such that the upper clamp can lower the non-rigid product a suitable distance before the lower clamp grips the non-rigid product so as to create as close as possible continuous movement as practical.

The present invention relates to methods and arrangements for locating services in a structured peer-to-peer distributed hash table, DHT, based, overlay communication network (310). The invention comprises two inter-related methods and nodes. The first method is used by a service node (321) to "advertise" to the overlay network (310) that it is providing a particular service (S1). This is done by distributing instances (351,352,353) of a service object (O1) that are stored in different nodes (331,332,333) in the overlay network (310) and where the instances (351,352,353) comprise an address to the service node (321). The other method is to locate at least one of these instances (351,352,353) with a predetermined probability and with a predetermined number of location request messages (390) from a user node (311) wishing to use the particular service (S1).
