Abstract: A system and a method for seawater pre-treatment and injection are disclosed. The seawater pre-treatment and injection system comprises at least one subsea water well connectable to a seawater injection system comprising at least a water injection pump in flow communication with a water injection well, wherein the subsea water well is made as a hole into a groundwater holding strata under the mud-line with a water permeable or non-permeable completion using the seafloor soil for filtration, with an inner tubing connectable to the seawater injection system via a valve.

Abstract: A cable reeling apparatus includes a plurality of reeling stations, a reel at each reeling station and a winding mechanism at each station for winding a cable onto the reel at the same station. The apparatus further includes a guide mechanism for selectively guiding the cable onto a first one of the reels and for transferring winding to a second reel when a sufficient length of cable has been wound on the first reel. The apparatus further includes an eccentric at each station for generating a loop in the cable when winding is commenced at a station.
