The occurrence

On , the bulk carrier Golden Cecilie was anchored at Anchorage C in Plumper Sound, British Columbia, with 20 people on board, when it collided with the bulk carrier Green K-Max 1 anchored at Anchorage B, after reporting a dragging anchor due to gusting wind. Following the collision, both vessels’ anchor chains became entangled. With the direction of a pilot on each vessel, and the assistance of two tugs, the anchor chains were disentangled and the two vessels returned under their own power to their respective anchorages and were secured in place. No pollution or injuries were reported, though both vessels sustained damage to their hulls.

TSB investigation process

There are 3 phases to a TSB investigation

  1. Field phase: a team of investigators examines the occurrence site and wreckage, interviews witnesses and collects pertinent information.
  2. Examination and analysis phase: the TSB reviews pertinent records, tests components of the wreckage in the lab, determines the sequence of events and identifies safety deficiencies. When safety deficiencies are suspected or confirmed, the TSB advises the appropriate authority without waiting until publication of the final report.
  3. Report phase: a confidential draft report is approved by the Board and sent to persons and corporations who are directly concerned by the report. They then have the opportunity to dispute or correct information they believe to be incorrect. The Board considers all representations before approving the final report, which is subsequently released to the public.

The TSB is an independent agency that investigates air, marine, pipeline, and rail transportation occurrences. Its sole aim is the advancement of transportation safety. It is not the function of the Board to assign fault or determine civil or criminal liability.
