CONTAINMENT SPECIAL
CASE STUDY - 8 NOT SO NEUTRAL
SITUATION: WELLBOAT COLLISION
INCIDENT: WELLBOAT LEFT IN SLOW AHEAD COLLIDED WITH PEN
RESPONSE: TRAINING The situation:
Wellboat use in Scottish fi sh farming is a very common activity. Wellboats are used not just for stock transfers, but also for assistance with grading and oth- er husbandry issues to provide a secure holding and transport facility for farm- ers to work their pens.
On the day in question, the weather conditions were good. The vessel was ap- proaching the pens – 70m circles – with the intention of mooring up adjacent to a specifi c pen to start work.
The incident:
At this point in time, the wellboat skipper went to put the engines into neu- tral to halt the vessel for a few moments prior to approaching the pens. An entire- ly routine operation – and something he would have done a thousand times before. On this occasion, however, although he thought he’d selected neutral, he’d inadvertently left the vessel in ‘slow ahead.’ Thinking that his vessel was stopped, the skipper briefl y looked else- where. But, in the intervening few sec- onds, the vessel slowly crept towards the nearby pen. A few seconds later he looked up and desperately put his vessel in to full astern. However, the collision was imminent and the resulting breach of the net allowed fi sh to escape.
THE RESPONSE
This is the only incident of its type that we’re aware of – suggesting that this is a ’one-off.’ However, it serves to remind us that we need to work with our contractors to address containment. And, no matter how good our contrac- tors, that human fallibility is an issue that’s diffi cult to design away. When discussing this incident for these case studies, the company highlighted the importance of training – not just for their own staff but also for those working in and around their sites.
