Techniques and methods to reduce downtime in an offshore platform (100), such as an offshore semi-submersible drilling rig (310) or drillship. Through the use of one or more movable platforms (322, 324) in a moon pool area, work on a riser string (5) passing through the moon pool area may be performed without exposing workers directly to the open sea below. Accordingly, the use of the one or more movable platforms (322, 324) in the moon pool area may provide protected access to the riser string (5) during, for example, harsh weather conditions.
