Professional Mariner - April 2018

この号では

Call it ice for the ages, the frigid opening to winter that took a toll on shipping interests from the St. Lawrence Seaway to the Ohio Valley. In its April issue, Professional Mariner covers barge breakaways caused by ice jams, a bulk carrier trapped in a lock, and multiple icebreaker rescues of vessels in distress. In the never-ending battle against hull fouling, we examine slippery liquid-infused porous surfaces (SLIPS), a new technology inspired by the pitcher plant that researchers hope will save maritime operators billions of dollars. Maritime tech developments are also extending into the sky, with a Dutch tugboat company employing drones to connect towlines to assisted vessels – find out how this project could soon improve safety on a tug near you. Our April issue also focuses on Davie Shipbuilding's Asterix, a converted containership now serving the Royal Canadian Navy; the threat posed by hackers manipulating loading data to endanger bulk carriers; and a difficult salvage near a busy Hawaii beach using a foam application technique common in the waters of Alaska. Turn to Professional Mariner for these stories and more, including full maritime casualty coverage.
