IOGP high potential event report

Incident description:

On Thursday, 13 September 2018, vessel was requested to support cargo offloading at a platform. She left the location at 10.42 hrs and expected to reach destination (55.5 km. from starting location) at speed of 8.0 knot (14.8 km/hr). Handover process from Chief Officer (C/O) to Master was performed at approx. distance 1.1 km from the platform (around 600 m. before entering 500 m. zone),but, with higher speed than recommended safe practice of 500 entering procedure and limit distance,the vessel speed could not be decreased in the limit time. Master tried to reduce speed to reach final speed at 0.6 knot (1.1 km/hr), but, the vessel could not be sopped. The master decided to activate reverse steering instead of drift away from platform. The vessel could not be fully astern and collided with a Platform and caused the platform label damage, support pipe broken and boat landing corner distorted.

What Went Wrong:

(1) No enforcement to follow the navigational offshore location procedure i.e. offset distance of vessel route and offshore platform and not follow 500m. zone entering safety check list (2) Competency of key person. Technical training was not provided to crew.

Corrective Actions:

- Conduct a 500m. zone re-entry audit to verify correct safe practices of PF approaching operation. Quarterly audit is considered. - Capt. Competency and vessel 500m. entering process shall be assessed and verified. Re-correct practice and process if found & required. - All Capt. And C/O shall be trained on how to use CPP controlling system and functional. This shall also including when emergency situation arise - All crews shall be communicated for the risk of not follow the steering asset / waypoint but not limit to other MAE of vessel operational. - Vessel owner is required to implement MOC reviews to determine the adequacy of temporary or permanent changes with respect to their HSE MS;
