TRANSOCEAN NORGE – RE ACTIVATION TRIAL_ ACTIVITY REPORT

Introduction
This report illustrates the tests completed during sea trial conducted on the Semisubmersible Drilling Rig
– West Regel. This report is solely based on my personal understandings and observations made during
the trial.
West Regel, A semisubmersible Drilling Rig which is built by Sembcorp Marine for the client (Sea Drill).
The original sea trial was completed in year 2015 from 27th Oct2015 to 7th Nov 2015 at South China Sea
and accepted by DNVGL and (Previous) Owner. Due to some unforeseen circumstances the owner of the
rig was changed to Transocean. The rig was only reactivated in 2018 for new client (Transocean). Since
the rig was ideal/not operational for a large period of almost 3 years combined with the owners request
SCM had to conduct a reactivation sea trail.
The second sea trails/reactivation sea trail was conducted from 9th Nov 2018 to 17th Nov 2018 at South
China Sea. During this second sea trial, not all tests were carried out whereas only few of the major
system activations/commissioning along with the few tests requested by the new owners were
conducted.
Note: This document does not contain the detail procedure neither the results of the sea trial.
