I always have worked with container vessels. Actually my job is Marine operator, being part of a team who is in charge to plan the vessels schedule, port stay, monitor and give all the required support to the captains and local stakeholders, always looking forward to delivery the costumer's cargo as promised and to save bunker (fuel) as much as possible, which contributes to the environment and company's pocket :) The challenges faced in my job usually are related to the bad weather, which decreases vessel's speed performance at sea, suspends in/out maneuvers into the port and also affects the operation performance in the ports. Consequently it generates port congestion, which brings a cascade effect to the onward ports, and it turns an additional challenge for us. Besides we have to deal with local stevedore strike, vessel's, crew and cargo incidents, damages and repairs. It could seems simple, if we were not talking about of a lots of different service lines, vessels and ports simultaneously. But although it's hard and stressful, I confess I really like it.
