Reporting of dynamic positioning events has climbed 20% year-on-year as vessel masters feel more confident about reporting them.
There were almost 100 reported incidents, undesired events and observations with DP systems in 2017 compared to around 80 the year before.
The International Marine Contractors Association (IMCA) received 98 reports of DP stationkeeping events in 2017 from 75 vessels. IMCA technical advisor Andy Goldsmith said this included 17 incidents of loss of DP ability, 56 undesired events and 25 observations of faults.
He told Riviera Maritime Media’s European Dynamic Positioning Conference in London on 6 February that the largest percentage of incidents was due to thruster and propulsion issues, while position reference and computer issues were also common.
He told OSJ on the sidelines of the conference that the increase in reporting was around 20% from around 80 in 2016 and 78 in 2015. He attributed this to improvements in reporting as IMCA changed the name of the reporting scheme in 2017 to reflect that it was not just DP incidents, but included the undesired events and observations.
Also during the morning session, Nautical Institute chief executive John Lloyd updated delegates on the organisation’s DP certification and training centre accreditation schemes. He said Nautical Institute introduced accreditation for DP refresher training at the beginning of February this year.
The institute has accredited 96 training centres and expects to add another five this year, compared with around 85 in 2015, according to Mr Lloyd.
Capt Lloyd said there were around 22,500 DP operators with valid certificates worldwide and this is expected to peak at 24,000 people during the year ahead. However, there has been a considerable drop in the number of new certifications from more than 3,000 in 2016 to 1,650 in 2017.
Offsetting this, Nautical Institute has increased the number of DP operator recertifications from about 1,000 in 2015 to about 3,000 in 2017. It has reduced the processing and return time of DP operator certification applications from four weeks in 2016 to around 10 working days this year.
During the session, DNV GL SeaSkill service manager Torsten Schröder said the class society had introduced a competence assurance scheme regarding technical personnel that are involved in DP, including electro-technical officers, engineers that maintain DP and watchkeepers that may affect DP integrity of a vessel or offshore oil and gas installation.
This would be in addition to the DP operator certification and assessment scheme that DNV GL introduced in 2014. So far, more than 430 candidates have passed DNV GL’s DP operator competence assessment scheme.
